About This Product
A Global Medium-Duty Rubber Flexible Cable for Indoor and Covered Portable Power
Medium Duty Rubber Flexible Cable is the global product family commonly specified as H05RR-F in European harmonised cable language and 60245 IEC 53 in IEC references. In China, the regional equivalent is normally referred to as YZ. The product is designed for flexible power connection of portable and movable equipment at 300/500V, where rubber flexibility and abrasion tolerance are needed but the application does not require a weather-resistant chloroprene outer sheath.
The construction is intentionally straightforward: fine-stranded flexible copper conductors, rubber insulation, and an ordinary rubber outer sheath. This gives the cable better flexibility and handling than many PVC cords, particularly in workshops, appliance leads, indoor extension sets, cleaning equipment, light portable tools, and covered commercial equipment. The important boundary is the absence of the N or W weather-resistant sheath. For routine outdoor use, long-term UV exposure, wet construction sites, or equipment that remains exposed to rain and sunlight, the correct upgrade is H05RN-F / 60245 IEC 57 / YZW rather than H05RR-F / YZ.
For international buyers, the safest way to specify this cable is to state the harmonised designation, voltage grade, core count, conductor size, sheath colour, and required documentation. A typical enquiry might read: H05RR-F, 3G1.5 mm², 300/500V, rubber flexible cable for indoor portable equipment, EN 50525-2-21 / IEC 60245-4 documentation required. If the destination market requires a specific approval mark, certification file, or local plug/cordset assembly standard, state that requirement at quotation stage so the cable, marking, packing, and test report can be aligned before production.
Cable Structure
Flexible Copper, Rubber Insulation, Ordinary Rubber Sheath
H05RR-F / 60245 IEC 53 is a medium-duty rubber flexible cable, not a heavy industrial feeder and not a weather-resistant neoprene cable. The construction below keeps the terminology conservative: conductor, insulation, cabling, and ordinary rubber sheath. Exact wall thickness, OD, and mass depend on size, core count, and the referenced production standard.
-
1
Conductors - Class 5 Flexible Copper
The conductor is normally fine-stranded annealed copper, typically aligned with IEC 60228 Class 5 flexible-conductor requirements. Tinned copper can be quoted where corrosion resistance or customer specification requires it, but bare copper is the standard choice for most appliance and workshop applications. Final strand construction should be checked against the factory datasheet for the exact size.
-
2
Insulation - Rubber Compound
Each conductor is insulated with a flexible rubber compound suitable for 300/500V rubber flexible cable service. In harmonised European specifications this is normally associated with H05RR-F construction under EN 50525-2-21. Core colours follow the required market convention, commonly including green-yellow for protective earth in G-type cables, blue for neutral, and brown/black/grey phase colours where applicable.
-
3
Core Assembly - Flexible Multi-Core Cabling
Insulated cores are cabled together to form a round, flexible construction suitable for portable equipment leads. Depending on the size and production design, fillers or separator materials may be used to support roundness and sheath extrusion. This layer is important for repeated handling because a well-cabled core assembly reduces twisting stress during coiling, uncoiling, and equipment movement.
-
4
Outer Sheath - Ordinary Rubber, Not Neoprene Weather Sheath
The outer sheath is an ordinary flexible rubber compound intended for medium-duty indoor, damp indoor, and covered portable-equipment use. This is the key difference from H05RN-F / YZW, which uses a chloroprene or equivalent weather-resistant sheath. H05RR-F is a good choice for flexible handling and moderate abrasion, but it should not be sold as a long-term outdoor UV/weather cable unless a project-specific datasheet and standard explicitly support that use.
Key Features
Rubber Flexibility for Medium-Duty Portable Equipment
This product is best positioned as a practical, cost-effective rubber flexible cable for global buyers who need 300/500V portable-equipment leads without paying for a weather-resistant chloroprene sheath. The six features below are written with that boundary in mind.
Flexible Rubber Handling
Compared with many PVC cords, rubber flexible cable remains easier to handle in workshops, appliance leads, and movable equipment connections. The fine-stranded conductor and rubber compound help the cable bend, coil, and route around equipment without feeling stiff or memory-prone. This is the main reason buyers choose H05RR-F over a basic PVC flexible cord.
300/500V Medium-Duty Rating
H05RR-F / 60245 IEC 53 sits above light 300/300V appliance cords and below heavy 450/750V industrial rubber cables. It is suited to small and medium portable loads, appliance leads, and indoor equipment wiring where 300/500V is the specified voltage class. For heavy three-phase feeders or demanding site power, move up to H07RN-F or equivalent heavy-duty cable.
Recognised Global Designations
The same product family can be discussed with different naming systems: H05RR-F in European harmonised language, 60245 IEC 53 in IEC references, and YZ in China. Presenting all three names helps international buyers, OEM engineers, and procurement teams recognise that they are discussing the same medium-duty ordinary rubber flexible cable family.
Good Fit for OEM Cordsets
The cable is commonly ordered for appliance leads and portable-equipment cordsets where the buyer controls plug type, cord length, sheath marking, packaging, and documentation. For OEM customers, the key quotation details are core count, conductor size, cable marking, sheath colour, approval requirement, packing length, and whether the cable will be supplied as bulk cable or assembled cordsets.
Lower Cost Than Weather-Resistant Rubber Cable
Because the sheath is ordinary rubber rather than chloroprene/neoprene, H05RR-F is normally more economical than H05RN-F of a comparable size. That cost advantage only makes sense when the environment is appropriate. If the cable will be exposed to sunlight, rain, oil-rich outdoor conditions, or harsher mechanical abuse, paying for H05RN-F or H07RN-F is the technically safer choice.
Clear Application Boundary
The product should be marketed honestly: medium-duty, rubber flexible, suitable for indoor and covered portable use, but not a permanent outdoor cable. This clarity reduces misapplication risk and improves buyer confidence. For distributors, the simple rule is: H05RR-F for ordinary rubber indoor/covered service, H05RN-F for medium-duty weather-resistant service, H07RN-F for heavy-duty outdoor industrial service.
How to Choose
Six Checks Before Specifying H05RR-F / 60245 IEC 53
Selection starts by confirming environment and voltage class. Once those are correct, the remaining decisions are core count, conductor size, certification, and packaging. If any answer points to outdoor weather, heavy mechanical stress, or fixed installation, select a different cable family rather than forcing H05RR-F into the wrong role.
Confirm the environment is indoor, damp indoor, or covered
Choose H05RR-F for indoor appliances, workshops, covered portable equipment, and general rubber cord use where the cable is not left in direct sunlight or rain. For routine outdoor work, gardening equipment, event power exposed to weather, or equipment stored outside, specify H05RN-F / YZW instead. The sheath difference matters more than the small price difference.
Check that 300/500V is the right voltage class
H05RR-F / 60245 IEC 53 is a 300/500V medium-duty cable. It is not intended to replace 450/750V heavy-duty rubber cable in industrial distribution circuits. If the project specification calls for H07, heavy-duty site power, construction feeders, generator leads, or higher mechanical stress, use H07RN-F, H07RR-F, or the relevant regional equivalent.
Select core count by equipment wiring
Two-core versions are used for double-insulated equipment that does not require a protective earth. Three-core G-type cables are used for earthed single-phase equipment. Four-core and five-core versions may be specified for small three-phase equipment or control-related portable leads, subject to the local standard and manufacturer size range. Always match the conductor colour code to the destination market.
Size the conductor from load, length, and installation condition
Do not choose conductor size from appearance alone. Current, cable length, ambient temperature, duty cycle, voltage drop, plug rating, and whether the cable is coiled all affect the final choice. For a professional quotation, provide equipment power, operating voltage, cord length, core count, country of use, and whether the cable will be used on a reel. Final ampacity should be checked against the project datasheet and local wiring rules.
Specify the exact designation for your market
For European or internationally written specifications, use H05RR-F and reference the required EN / IEC documentation. For China-focused specifications, YZ may be used as the regional designation. For buyers using older UK trade terminology, 318-TRS may appear in enquiries. If certification marks are required, confirm them before order; do not assume every rubber cable carries every local approval.
Plan marking, packaging, and documentation early
For OEM cordset buyers, sheath marking and packaging are part of the product. State the cable legend, brand marking, metre mark requirement, drum or coil length, packing label language, and required test reports. For distribution stock, standard black sheath and standard coil/drum lengths are usually simplest. Custom colours, private-label marking, and plug assemblies should be quoted separately.
Applications
Where H05RR-F Makes Sense - and Where It Does Not
The strongest applications are indoor and covered portable-equipment leads where rubber flexibility improves handling but a weather-resistant sheath is not necessary. The four groups below are typical, not exhaustive. Always check the equipment manual and local wiring rules before final selection.
Household & Commercial Appliances
Rubber flexible leads for appliances, kitchen equipment, cleaning machines, portable heaters where allowed, fans, and commercial-use equipment that requires better flexibility than PVC. H05RR-F is appropriate when the cord is used indoors or under cover and the equipment standard permits a medium-duty rubber flexible cable.
Light Workshop Tools
Indoor drills, grinders, bench tools, small portable machines, inspection lamps, and temporary power leads in dry or damp workshop conditions. For tools used outdoors, on construction sites, or in oil-rich environments, move to H05RN-F or H07RN-F depending on mechanical duty and voltage class.
Covered Event & Audio Equipment
Flexible leads for indoor stages, covered audio equipment, portable lighting, exhibition booths, and temporary commercial setups where cables are handled frequently but not exposed to open weather. For outdoor festivals, wet grass, road-crossing cable routes, or generator distribution, specify weather-resistant and heavier-duty rubber cable.
OEM Cordsets & Portable Leads
Bulk cable for OEM cordset manufacturing, private-label appliance leads, replacement equipment cords, and distributor stock. Buyers commonly specify conductor size, core count, cord length, plug type, sheath marking, packing method, and destination-market documentation together so the finished cordset is compliant and ready for sale.
Not appropriate for: Long-term outdoor weather exposure (use H05RN-F / YZW or H07RN-F / YCW depending on duty). Heavy construction-site feeders and generator leads (use heavy-duty 450/750V rubber cable). Fixed building wiring (use the specified building cable such as XLPE/PVC or LSZH cable). Welding circuits (use dedicated welding cable such as H01N2-D / YH). Mining portable equipment (use certified mining cable). Continuous immersion or submersible pumps (use a cable specifically approved for water immersion).
Technical Data
H05RR-F / 60245 IEC 53 Ordering Range
The table below is intentionally conservative. It gives common ordering families and selection notes rather than unverified OD, weight, or ampacity values. For final engineering use, request the project datasheet for the exact conductor size, core count, sheath thickness, outside diameter, mass, DC resistance, and current-carrying capacity under the actual installation condition.
| Common Configuration | Voltage Class | Conductor | Typical Use | Selection Note |
|---|---|---|---|---|
| 2-core small sizes | 300/500V | Flexible copper, usually Class 5 | Double-insulated appliances and portable equipment without protective earth | Confirm whether the destination-market equipment standard permits 2-core connection. |
| 3G small sizes | 300/500V | Flexible copper, usually Class 5 | Earthed single-phase appliances, light tools, cleaning machines, portable lamps | The G designation normally indicates a green-yellow protective earth conductor. |
| 4-core configurations | 300/500V | Flexible copper, usually Class 5 | Small three-phase equipment or special portable leads | Check phase colour requirements and local availability before quoting. |
| 5G configurations | 300/500V | Flexible copper, usually Class 5 | Three-phase plus neutral and earth for small movable equipment | Use only where equipment wiring and plug/socket system require five conductors. |
| Larger medium-duty sizes | 300/500V | Flexible copper, usually Class 5 | Higher-current portable equipment within the medium-duty family | If current, voltage drop, or mechanical duty increases, review H07RR-F or H07RN-F instead. |
| Custom OEM cable marking | 300/500V | Bare or tinned copper on request | Private-label cordsets, distributor stock, appliance manufacturers | Specify sheath legend, metre marking, colour, packing length, and documentation at enquiry stage. |
Reference standards for this product family normally include IEC 60245-4 and EN 50525-2-21 for H05RR-F, with regional equivalents such as YZ under Chinese rubber-cable practice. Because product availability and exact dimensional tables vary by manufacturer and market, do not use this page as a substitute for a signed datasheet, type test report, or destination-market approval document.
For enquiries, provide: cable designation, voltage grade, core count, conductor size, length, sheath colour, marking requirement, packing method, destination country, and required documents. For cord reels or long extension leads, voltage drop and coiled-cable derating must be checked separately.
Comparison
Positioning H05RR-F in the Rubber Flexible Cable Family
Rubber flexible cable selection is mainly a question of voltage class, sheath compound, mechanical duty, and environment. H05RR-F is the ordinary medium-duty rubber option. It should not be confused with H05RN-F, which is the medium-duty weather-resistant upgrade, or H07RN-F, which is the heavy-duty outdoor industrial cable.
| Attribute | H05RR-F / 60245 IEC 53 (this product) | H05RN-F / 60245 IEC 57 | H07RN-F / 60245 IEC 66 | H03RR-F / 60245 IEC 51 |
|---|---|---|---|---|
| Duty level | Medium duty | Medium duty, weather-resistant | Heavy duty, industrial outdoor | Light duty |
| Voltage class | 300/500 V | 300/500 V | 450/750 V | 300/300 V |
| Outer sheath type | Ordinary rubber | Chloroprene or equivalent weather-resistant sheath | Chloroprene or equivalent heavy-duty sheath | Ordinary rubber |
| Typical regional equivalent | YZ in China | YZW in China | YCW or similar heavy-duty regional family | YQ or similar light-duty family |
| Best use | Indoor and covered portable equipment | Outdoor portable equipment and weather-exposed medium-duty cords | Construction sites, generators, heavy industrial portable power | Small domestic appliances and very light leads |
| Outdoor suitability | Not for long-term weather exposure | Suitable where specified for outdoor medium-duty service | Suitable where specified for heavy outdoor service | Not for outdoor service |
| Cost logic | Economical rubber flexible option | Higher cost for weather-resistant sheath | Highest cost but strongest duty class | Lowest cost, smallest duty class |
| When to avoid | Sun, rain, site abuse, heavy feeders | Heavy 450/750V industrial feeders | Small appliances where over-specified | Medium-duty tools and rough handling |
When to choose H05RR-F
Choose H05RR-F when the customer needs a flexible rubber cable for indoor or covered portable equipment at 300/500V, and when ordinary rubber sheath performance is sufficient. It is a sensible option for appliance leads, light tools, covered workshop equipment, distributor stock, and OEM cordsets where cost, flexibility, and recognised designation matter.
When to choose an alternative
Choose H05RN-F / YZW when medium-duty weather resistance is required. Choose H07RN-F / YCW when the application is heavy-duty, outdoor, or industrial. Choose H03RR-F only for very light appliance cords where 300/300V and light-duty construction are acceptable. Choose building wire, welding cable, mining cable, or submersible cable where those specialised applications apply.
Frequently Asked Questions
Common Questions From Global Buyers and OEM Cordset Manufacturers
Is Medium Duty Rubber Flexible Cable the same as H05RR-F?
In many international enquiries, yes. The product is commonly specified as H05RR-F under European harmonised cable terminology and 60245 IEC 53 under IEC references. In China, YZ is the common regional designation for the ordinary medium-duty rubber flexible cable. When ordering globally, use the exact designation required by your destination market and request the matching documentation.
What is the difference between H05RR-F and H05RN-F?
The main difference is the sheath. H05RR-F uses an ordinary rubber outer sheath and is aimed at indoor, damp indoor, and covered portable-equipment service. H05RN-F uses a chloroprene or equivalent weather-resistant outer sheath and is the better choice for outdoor medium-duty service. Both are 300/500V families, but the environment is different. If the cable will see UV, rain, outdoor storage, or weather-exposed use, do not substitute H05RR-F for H05RN-F.
Can H05RR-F be used outdoors?
It should not be promoted as a long-term outdoor weather cable. Occasional covered or temporary use may be acceptable depending on the equipment standard and site rules, but direct sun, rain, wet ground, and outdoor storage call for a weather-resistant rubber cable such as H05RN-F or H07RN-F. The safest commercial advice is simple: H05RR-F for indoor and covered service; H05RN-F for medium-duty outdoor weather service.
How do I choose conductor size?
Choose conductor size from equipment current, supply voltage, cord length, voltage-drop limit, plug/socket rating, duty cycle, ambient temperature, and whether the cable will be used coiled or fully extended. For OEM cordsets, also check the product safety standard for the appliance or equipment. If the enquiry only says “medium duty rubber cable” without load and length, ask for the application details before quoting the final size.
Can this cable be used on extension reels?
Yes, it can be used for suitable indoor or covered extension leads and reels when the cable size, plug rating, and reel design are correctly selected. The critical warning is heat: a coiled cable cannot dissipate heat as well as a fully extended cable. Reel manufacturers usually state separate ratings for coiled and fully unwound use. Running a coiled reel at the full unwound rating can overheat the cable and damage the insulation.
What documents should global buyers request?
At minimum, request the product datasheet, factory routine test report, packing list, certificate of origin if needed, and the relevant compliance statement for the standard named in the purchase order. If the destination market requires a specific mark or certification, state that requirement before ordering. Do not assume that a cable marked with a generic type name automatically carries every local approval.
Installation & Handling Tips
Six Practices for Safer Medium-Duty Rubber Cord Use
Most failures in flexible cords come from misuse: wrong environment, tight bending, damaged plug entries, crushed cable, or operating a coiled lead at too high a load. These practices help distributors, OEMs, and end users keep H05RR-F in the application range it was designed for.
Keep it out of long-term sun and rain
Ordinary rubber sheath is not the same as chloroprene weather-resistant sheath. Store and use H05RR-F indoors or under cover. If the cable must be left outdoors, exposed to sunlight, dragged through wet ground, or used in changing weather, specify H05RN-F or H07RN-F instead of trying to stretch the application boundary.
Unwind reels before high-load use
Cable on a reel heats faster than cable laid out straight. Always follow the reel maker’s rating for coiled and uncoiled operation. For portable tools, heaters, cleaning machines, and workshop loads, fully unwind the cable before running near rated current. Heat damage from coiled operation is avoidable and common.
Use proper strain relief at plugs
The plug entry is often the first failure point in flexible leads. Use plug bodies and cord grips that match the cable OD, and avoid pulling equipment by the cable. For OEM cordsets, specify the plug, strain relief, cable OD range, and pull-test requirement together so the finished lead is mechanically reliable.
Avoid crushing and sharp edges
Medium-duty rubber cable tolerates normal handling, but it is not designed to be crushed by wheels, trapped under doors, cut by sheet metal, or run across vehicle routes without protection. Use cable protectors or reroute the lead where people, carts, or equipment will repeatedly cross the cable.
Inspect sheath and plug entries regularly
Look for cracked sheath, exposed conductor, flattened sections, soft or swollen rubber, loose plug glands, and warm plug bodies during use. Remove damaged leads from service immediately. Flexible-cord safety depends on both the cable and the accessories connected to it.
Store loosely coiled and dry
Store the cable dry, off the floor, and away from sharp edges, solvents, direct heat, and prolonged sunlight. Use large-radius coils rather than tight loops. For OEM stock, keep coils or drums wrapped until use so the sheath stays clean and the cable marking remains readable.
Safety note: Flexible cord selection and installation must follow the equipment standard and the wiring rules of the destination country. H05RR-F is a cable component, not a universal permission to connect any load. For outdoor, wet, high-current, hazardous, mining, welding, or fixed-building applications, use the cable family specifically approved for that service.
