H07RN-F BS EN 50525-2-21 Flexible Rubber Cable

H07RN-F Heavy-Duty Flexible Rubber Cable — 450/750V (BS EN 50525-2-21)

H07RN-F is a heavy-duty flexible rubber cable rated at 450/750V for power tools, industrial machinery, construction site equipment, and outdoor temporary power installations. Robust chloroprene (neoprene) outer sheath combined with vulcanised rubber insulation delivers exceptional mechanical toughness, oil resistance, and flexibility in demanding environments.

Compliant with BS EN 50525-2-21 and IEC 60245-4, H07RN-F is one of the most widely specified rubber flexible cables globally. Available in 1 to 5 cores and cross-sections from 1.5 mm² to 240 mm².

Key Design Features

• Class 5 fine-wire annealed copper conductors for maximum flexibility
• Vulcanised rubber (EPR or equivalent) core insulation
• Chloroprene (neoprene) outer sheath — superior oil, weather, and UV resistance
• Rated voltage 450/750V; temperature range ‑40°C to +90°C
• 1 to 5 cores; 1.5 mm² to 240 mm²
• Flame-retardant sheath compound to reduce fire spread
• Resistant to mechanical impact, abrasion, and repeated flexing
• BS / IEC harmonised designation for global acceptance

Selection Guide

Why H07RN-F Over PVC Flexible Cable?

H07RN-F withstands ‑40°C to +90°C vs ‑15°C to +70°C for PVC equivalents. Its neoprene sheath resists oils, fuels, ozone, and UV — the preferred choice wherever PVC would stiffen, crack, or degrade.

Large Cross-Section Availability
