  再一个对于中压电缆 现场敷设过程出现的护套破损现象的处理,不能过于粗糙,一个是电缆的敷设过程必须请拿轻放,再一个电缆出现外部破损后,其内部绝缘的破坏情况有时是不好说的,笔者曾经对现场敷设过程施工不小心造成外护套多处破损的电缆进行过返厂试验,发现电缆的破损部位出现了局部放电超标和击穿现象,因此对于中压电力电缆的在现场敷设过程出现外护套破损后,是截断做中间接头或重新更换电缆,因为对电缆破损部位进行护套修补后,可能存在使用隐患。


  事实证明,对于低压电缆绝缘和护套的修补必须是电缆损伤较为轻微的,仅仅是绝缘和护套出现损伤,电缆其他结构完好无损的前提下,才能进行绝缘和护套的修补,而中高压电缆的要求可能更为苛刻,现在的有些工程的电缆输电为了减少电缆的中间接头的数量,电缆全部采用大长度单芯电缆,由于线路的敷设距离较长及地形负责,及施工人员的配备数量及缺乏专业的电缆敷设设备等因素,施工过程造成电缆护套破损出现几率大大增加。
