H07RN-F Wire

H07RN-F wire is a heavy-duty, European harmonized rubber cable renowned for its exceptional durability and resilience in harsh environments. Often referred to as rubber flexible cable, reeling cable, or H07RN-F power cable, it is specifically designed for applications requiring high mechanical strength and resistance to outdoor elements. This cable is the industry standard for power supply in construction sites, industrial machinery, and outdoor events due to its robust neoprene rubber sheath.

Standards

IEC60245, BS EN50525-2-21, GB/T5013.4

As a harmonized cable, H07RN-F complies with the essential European standards, ensuring reliable performance and safety. It is manufactured in accordance with EN 50525-2-21 and DIN VDE 0285-525-2-21 . The "H" designation confirms it is a harmonised cable, approved for use across all CENELEC countries, and it bears the CE mark to verify conformity with the Low Voltage Directive.

Construction

The construction of H07RN-F is specifically engineered to withstand extreme conditions:

 Conductor: Class 5 flexible bare copper conductors according to IEC 60228, made of finely stranded wires to ensure maximum flexibility for frequent movement and bending.

Insulation: Each core is insulated with a high-grade EPR (Ethylene Propylene Rubber) rubber compound, providing excellent electrical insulation and thermal resistance.

Outer Sheath: The cores are bundled and encased in a heavy-duty PCP (Polychloroprene) rubber sheath, commonly known as neoprene. This robust outer layer provides superior resistance to abrasion, oils, chemicals, UV radiation, ozone, and water.

Characteristics

Voltage Rated U0/ U: and 450/750V.

Note:

U0: Rated power-frequency voltage between conductor and earth for which the cable is suitable.

U: Rated power-frequency voltage between phase conductors for which the cable is suitable.

Temperature Rating : Fixed : -30℃ to 60℃ ; Fixed protected installations : +85℃ .

Minimum Bending Radius: Fixed: 4 x overall diameter;

Flexed: 6 x overall diameter.

Application

The superior durability of H07RN-F makes it the go-to cable for demanding environments. Common H07RN-F applications include:

Construction Sites: Power supply for heavy tools, lighting towers, and temporary site distribution boards.

Industrial Machinery: Connection for motors, pumps, welding equipment, and portable generators.

Outdoor Events: Power distribution for stages, sound systems, and catering equipment at festivals or open-air venues.

Agricultural and Port Environments: Use in farms, docks, and shipyards where exposure to water, oil, and mechanical stress is prevalent.

Reeling Applications: For use on cable reels and cranes where the cable is frequently wound and unwound.
