Uses: This product is suitable for fixed installation in AC 50Hz, voltage level at 1kV and below for supplying electric power transmission and distribution wires on the road with; mainly used in power plants, petrochemical, iron and steel plants, tunnels, paper, substation and computer centers flame retardant requirements of the occasion. Retardant wire and cable characteristics: flame retardant wire and cable refers to a cable wire and cable laying when the beam has prevented retardant properties, it can be wire and cable burning zone limit in the range of 2.5m, so that the fire loss decreases . The main technical performance: (1) fire-retardant properties of the finished cable meets GB / T19666 standards. (2) Production of polymer materials flame retardant cable oxygen index is between 28 to 33.
