Flame-retardant cable classification: according to the different flame-retardant materials of cables, flame-retardant cables are divided into halogen flame-retardant cables and halogen-free low-smoke flame-retardant cables. Which contain halogen flame retardant cable insulation, sheath, outer sheath and auxiliary material (package belt and filling) in whole or in part by polyethylene (PVC) containing halogen flame retardant material, thus has good flame retardant properties. However, when the cable burns, a large amount of smoke and haloic acid gas will be released. Haloic acid gas is corrosive to the surrounding electrical e When the cable burns, it will cause harm to the surrounding electrical e and rescue personnel, which is not conducive to the fire fighting and rescue work, thus causing serious "secondary hazards". All or part of the insulation layer, protective sleeve, outer protective layer and auxiliary materials (packing belt and filling) of the halogen-free low-smoke flame-retardant cable are adopted

　　 电缆直埋安装时，1-35KV电缆直埋深度不小于0.7m。 10KV及以下电缆平行安装时，相互净距不小于0.1m，10-35KV不小于0.25m；交叉安装时距离不小于0.5m。 电缆敷设温度不低于0℃，弯曲半径：多芯电缆≥15(D+d)，单芯电缆≥20(D+d)，（D为电缆外径，d为导体外径）。

　　可以采用任何一种方式敷设，更适用于岩石地区的直埋敷设。HYA53、HYA553型号电缆只限于特殊情况下使用,使用时必须进行气压维护。有阻燃。在一定条件下，也可用于传输2048kbit/s以上的数字信号。

TB8：在方式3中，TB8是发送机要发送的第9位数据。在多机通信中它代表传输的地址或数据，TB8=0为数据，TB8=1时为地址。RB8：在方式3中，RB8是接收机接收到的第9位数据，该数据正好来自发送机的TB8，从而识别接收到的数据特征。TI：串行口发送中断请求标志。当CPU发送完一串行数据后，此时SBUF寄存器为空，硬件使TI置1，请求中断。CPU响应中断后，由软件对TI清零。RI：串行口接收中断请求标志。

　　6KV及以上电缆接头：①安装电缆终端头时，必须剥除半导体电屏蔽层，操作时不得损伤绝缘，应避免刀痕凹凸不平的情况，必要时用砂纸磨平；屏蔽端部应平整，并要把石墨层（碳粒）清除干净。②塑料绝缘电缆端头铜带屏蔽和钢铠必须良好接地，对短路也遵循这项原则，避免三相不平衡运行时钢铠端部产生感应电动势，甚至“打火”及燃烧护套等事故。

Plastic insulated power cable insulation layer for plastic power cable. The commonly used plastics are polychlorinated, polychlorinated and poly. Plastic cable structure is simple, easy to manufacture and process, light weight, easy to install and lay. Therefore, it is widely used as medium - low - voltage cable, and has the tendency to replace the viscous impregnated oil-paper cable. Its major drawback is the existence of dendritic breakdown, which makes it used at higher voltage.
