　　阻燃性能在规定试验条件下，试样被燃烧，在撤去试验火源后，火焰的蔓延仅在限定范围内，残焰或残灼在限定时间内能自行熄灭的特性。天津市电缆总厂第一分厂专业生产研发的市内通信电缆，电话电缆，大对数通信电缆，计算机电缆，通信设备电源线；铁路信号电缆，各种性证书齐全，质量可靠。



　　电缆地线芯绝缘采用具有抗氧化性能的K型B类低密度聚乙烯。聚乙烯的绝缘电阻高，耐电压好，介电系数小和介质损耗温度和变频率的影响也小，不但能满足传输性能的要求，而且能确保电缆的使用寿命。为了减少回路间的相互串扰和外部干扰，电缆采用屏蔽结构。

两相空气开关又称2P空气开关，它的接线如下图所示，如果空气开关没有标记L与N，那就按照左零右火的习惯接线就好。一般空气开关用在线路中作为总开关，而漏电开关作为支路的开关，所以正常的接法应该是空气开关－－漏电开关。为什么要这样接呢，从它的功能上我们就可以知道，如果把漏电开关接在空气断路器的前面。因为漏电开关一旦出现漏电就会切断电源，而空气开关在这个时候不会作出反应，就会导致越级跳闸的现象出现。

以免用户外出时家里停电，导致恢复供电后自己家不能合闸所有插座回路，无论是普通插座回路还是大功率插座回路，都建议使用漏电保护器。照明回路不需要附件——照明回路电流小、灯具高，即使漏电也没有太大危害。加上现如今的LED灯具质量堪忧，安装漏电附件后反而容易引起跳闸——而且无解。后套用数据家用开关有一套固定的参数，型号选择DZ47型或相应的改造型号——DZ47是国际通用型号名称，除此以外，各厂家还出了自己研发的型号。
