APPLICATIONS
Fire resistant cable is mainly featured with normal operation for certain time during fire besides power transmission under normal operating condiction, and is applicable to nuclear stations, subway, tunnels, high buildings and other places related to fire prevention and security, firefighting and lifesaving.
NH-VV is a fire resistant cable, specially designed to ensure the power supply to emergency circuits in the event of fire. During a fire you need critical circuits to work for life safety (signaling lights, fume extractors, acustic alarms, water pumps, etc) and a secure plant shutdown. For this reason, its use is highly recommended in public places such as: hospitals, tunnels, offices, production plants, laboratories, hotels, etc.
