　　 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。

Flame-retardant cable: the electric wire and cable are produced by external heating. In order to achieve the purpose of flame retardant, the three elements must be caused, namely, combustible gas, heat and oxygen. Therefore, generally USES is added in the sheath material containing halogen halide and metal oxide, from the perspective of flame retardant, that's very good, but, because of the halide is contained in these materials, in a lot of smoke and released when halogenated body, so, the low visibility when fire, bring a lot of personnel evacuation and fire obstruction, whereas people more for functioning suffocated to death.
