Due to the processing of materials surface locally alternating instantly melt and cooling, thermal stress on the surface of the material makes micro cracks and micro holes.recast layer present in the recast layer.
Discharge energy under a certain level, the surface of the material can avoid the emergence of micro cracks, as to low thermal conductivity materials appear, its micro cracks are more obvious.
(2) There many ways of spark erosion material forming pits, and they are interact with each other, together to complete the surface processing of materials.

This phenomenon will cause the protective material easily broken, due to the large thermal expansion coefficient difference between cable body and protective materials, such as thermal expansion coefficient of the black PE pipe is about 6 times of cement and steel. 6) Protective material aging.
Although the materials of the suspenders and tied members were similar, the work environment was different, so their damages encountered had both similarity and difference.
