Cable water hazard After the cable water enters, the water tree aging phenomenon will occur under the action of the electric field, which will cause the cable to break down. Water trees are collections of water-filled voids with a diameter of 0.1m to a few microns. The existence of impurities, pores in the insulation, and the local high electric field formed by the unevenness of the interface between the insulation and the inner and outer semiconductive layers are the starting points for the occurrence of water trees.
