H07RN-8-F BS EN 50525-2-21 Flexible Rubber Cable
Product Overview
The H07RN-8-F is a low voltage flexible rubber cable designed for installation in dry, damp, or wet environments, including workshops with explosive atmospheres. It can be immersed in fresh water up to 10 m depth and may be used as an energy supply cable for submersed pumps. It is not suitable for underwater power transmission or installation in a waterway, or where mechanical damage might occur and cause hazard.
The cable is intended for connections liable to moderate mechanical stresses, such as industrial or agricultural workshop apparatus, large boilers, heater plates, electric tools (e.g., drills and disk saws), electric appliances, portable motors and generators on building sites. It is also suitable for fixed installations along floors or shelving on temporary job sites, for connecting structural elements in lifting apparatus, machinery, etc. It is suitable for applications up to 1 kV for adequately protected fixed installations (e.g., inside pipes or equipment) as well as for rotor connections to lifting equipment motors.
The cable is manufactured according to BS EN 50525-2-21, HD 22.4S3, CEI 20-19 Part 16, BS EN 60228, and VDE 0295, with flame retardant performance according to BS EN/IEC 60332-1-2.
