The paper introduced a method that can locate the position of cable breaking point by using the reflection of low pressure impulse, and set up a control system through 89c52.
介绍了一种利用低压脉冲反射法测定电缆断点位置的方法，并采用89c52单片机建立了控制系统。
Liquid silicon rubber injection moulding has constant cooling pressure to the cable. It is Low in electricity output while "breathing" together the cable.
液体硅橡胶注射成型对电缆本体有恒定的收缩的收缩压力，与电缆同“呼吸”局部放电最低。
