The secondary cable is the important bridge connecting the primary equipment and the secondary equipment
and the insulation reliability will affect the operation reliability of the secondary equipment. Trough field sampling and dissecting the accident cable
it is found that the causes of insulation defects of secondary cable are cable head damage
moisture intrusion
meterial and structure defects and operation inspection management defects
