single-phase ground fault prevention measures

Timely pruning the tree line where the obvious contradiction between the trees.

Lightning protection measures taken to reduce the lightning caused the single-phase fault. In addition, in order to reduce the surface of the insulator and porcelain skirt inner product contamination or poor manufacturing quality moisture after rain, and flashover discharge, resulting in a ground fault occurs in the line construction (reconstruction) must choose qualified, good quality of insulators, and pressure test prior to installation, ensure the installation quality.


In the peak load, the use of an infrared thermometer to measure the temperature of the wire joints, once found abnormal temperature, treated immediately, to avoid the heat fuse wire.

short-circuit fault prevention measures

Measures to prevent external damage

In order to reduce vehicle collision accident tower, try to migrate tower, it can not migrate suspended striking the reflective paint brand in the tower, to cause the vehicle driver's attention.
