H07BN4-F Rubber Cables

H07BN4-F Extra-Heavy-Duty Rubber Cable — 450/750V, Heat & Oil Resistant

H07BN4-F is an extra-heavy-duty flexible rubber cable rated at 450/750V with outstanding resistance to heat, oil, ozone, and aggressive industrial environments. EPR insulation and a specially compounded polychloroprene (BN4) outer sheath — offering performance superior to standard neoprene — make H07BN4-F the preferred choice in petrochemical, steel, shipbuilding, and foundry environments.

Manufactured to DIN VDE 0282-10 and EN 50525-2-82, H07BN4-F is available in 1 to 5 cores, 1.5 mm² to 240 mm², with temperature ratings from ‑40°C to +90°C (intermittent +110°C).

Key Design Features

• Class 5 extra-fine-wire annealed copper conductors
• EPR rubber core insulation — superior electrical performance at elevated temperatures

Selection Guide

H07BN4-F vs H07RN-F

H07BN4-F offers higher heat resistance (continuous +90°C vs +60°C for standard H07RN-F), better oil immersion resistance, and superior resistance to aggressive industrial chemicals. Specify H07BN4-F wherever H07RN-F service life is shortened by thermal or chemical degradation.
