Fire-resistant cables can still ensure the normal operation of the line in a certain time when burning. It is different from the general flame-retardant cable, if there is a fire, you can continue to power transmission. The use of this product will enable high-rise buildings, subways, power plants and other major occasions have better fire safety and fire rescue capabilities.
Cables are intended for transfer and distribution of electric energy and electric signals in stationary installations at an a. c. voltage not more 1000 V and frequency 100 Hz, and at constant voltage not more 1000 V.
Cables take the fiberglass tape as barrier and can be used for lay cable in buildings and premises, including in volatile areas of all classes, except the explosive areas of class B-1. Lying of cables without heating can be done at or below –15°C.
Maximum temperature lived, when a short circuit — not exceeding 250°C. Extreme temperature of conductive wires lived on the condition fire resistance of cable in the short-circuit is 400°C.
