Abstract

In recent years, white defects in power cable buffer layer has been discovered many times around the world. It would be a hazard to electricity transmission if these defects are not detected and solved in time, finally resulting in a power outage. In this paper, the selection of a physics field and the building of a three-dimensional model on cable electric field simulation are mentioned and improved. The distribution of electric field was calculated with two factors: the gap between water-blocking tape and aluminum sheath, the conductivity of water-blocking tape. The results demonstrated that the existence of the gap increases the electric field intensity in the air layer. Increasing the conductivity of water-blocking tape is beneficial to reduce the electric field intensity. It was explained that white defects is closely related to the air discharge in buffer layer.
