H07RN8-F BS EN 50525-2-21 Flexible Rubber Cable

H07RN8-F Heavy-Duty Rubber Cable — 450/750V, Enhanced Weather & Oil Resistance

H07RN8-F is a premium heavy-duty flexible rubber cable rated at 450/750V, offering enhanced resistance to oils, ozone, weathering, and UV radiation compared to standard H07RN-F. The "N8" sheath designation indicates a specially compounded chloroprene rubber with improved thermal stability, making it suitable for continuous outdoor use in harsh industrial and marine environments.

Manufactured to BS EN 50525-2-21, H07RN8-F is available in 1 to 5 cores with conductor cross-sections from 1.5 mm² to 95 mm². It is the preferred choice for heavy outdoor portable tools, marine shore-power leads, and mobile construction plant where long-term outdoor exposure is expected.

Selection Guide

H07RN8-F vs H07RN-F

H07RN8-F uses an enhanced N8 sheath compound that outperforms standard H07RN-F neoprene in UV resistance, oil immersion, and high-temperature stability. Specify H07RN8-F for applications with continuous outdoor UV exposure or frequent oil contact.
