Cables are the arteries of modern industry, carrying electrical energy to the tools, machines, and systems that power our economies. Among the many types available, H07RN-F and A07RN-F 450/750V Harmonized Rubber Cables stand out for their versatility, durability, and safety. These cables are widely used across Europe, Asia, and increasingly in South Africa’s mining and industrial sectors, where harsh environments and demanding applications require exceptional performance.

What Are H07RN-F and A07RN-F Cables?

H07RN-F and A07RN-F are harmonized rubber cables standardized under DIN VDE 0282 and HD 22 series of standards.

• Voltage Rating: 450/750V, making them suitable for medium-duty to heavy-duty applications.

• Insulation & Sheath: Made with high-quality rubber compounds that provide flexibility, mechanical strength, and resistance to oil, abrasion, and chemicals.

• Conductor: Stranded copper, Class 5 according to DIN VDE 0295 / HD 383 S2, which ensures good conductivity and flexibility.

The H07RN-F designation follows the HAR (Harmonized Cable Type) coding system:

• H = Harmonized cable according to European standards.

• 07 = Voltage rating of 450/750V.

• R = Rubber insulation.

• N = Polychloroprene or equivalent synthetic rubber outer sheath.

• F = Flexible cable.

The A07RN-F is a closely related version with minor variations in national applications, often referenced in agriculture and industrial settings.

Benefits of H07RN-F / A07RN-F Cables

1. Flexibility and Mobility

   • Suitable for equipment that needs frequent movement, such as portable motors and welding machines.

2. Durability Under Harsh Conditions

   • Resistant to abrasion, oils, greases, chemicals, and weathering, making them ideal for outdoor and mining use.

3. Safety in Hazardous Areas

   • Certified for use in explosion-hazard zones, where sparks or faulty insulation could cause catastrophic damage.

4. Long Service Life

   • Rubber materials resist cracking and maintain elasticity over years of operation.

5. Wide Range of Sizes

   • Available from 1×1.5 mm² to 1×630 mm², enabling use from handheld tools to large industrial equipment.

6. Harmonized Standards

   • Ensures international compatibility, which is especially useful in South Africa where mining equipment is often imported.

Applications

H07RN-F and A07RN-F cables are multi-purpose workhorses. Common applications include:

• Mining: Powering drilling equipment, mobile transformers, conveyor systems, and ventilation fans in underground mines.

• Construction Sites: Temporary power distribution, lighting, and heavy-duty power tools.

• Industrial Plants: Motors, welding machines, and portable tools.

• Agriculture: Irrigation pumps, mobile units, and automated machinery.

• Energy Sector: Suitable for generators and backup power installations.

• Explosion-Hazard Areas: Certified use in oil & gas facilities or chemical plants.

The H07RN-F and A07RN-F 450/750V Harmonized Rubber Cables represent one of the most versatile, safe, and durable solutions for industries that demand reliable power. Their robust construction, resistance to chemicals and abrasion, and compliance with harmonized standards make them a trusted choice in South Africa’s mining, construction, agriculture, and energy sectors.

By investing in these high-quality cables, industries reduce downtime, improve safety, and ensure long-term efficiency—an increasingly critical factor in South Africa’s evolving industrial landscape.
