低卤低烟阻燃电力电缆的详细介绍

一、用途Application
本产品适用于发电厂、变电站、矿山、石化、钢铁 厂、高层建筑、隧道、轮船、人防工程、广播台、电视台、电话交换及电子计算机巾心等阻燃要求较高的场合。
These wires & cables are suitable for use in power plants, substations, nuclear power station, mines, petrochemical industry, iron & steel plants, high-rise buildings, subway, tunnel, ships, civil air defense projects, broadcast stations, TV station, telephone exchange, computer centres etc where flame retardancy of cables is highly required.
二、低卤低烟阻燃电力电缆的特点
Characteristics of low smoke low halogen content flame retardant (FR) Power Cables
低卤低烟阻燃电力电缆是指在实际火灾中,组成电缆的高聚物被燃烧所释放出的烟雾、HCl含量较少使火灾的”二次伤害”损失减小。
For 1ow smoke low halogen content FR wire&cables, the smoke evolved when the polymeric components in cables are burned in an actual fire and HCI contained in the smoke are small in quantity, which reduces the loss of the ”secondary disaster” of the fire
