Influence of Conductivity Parameters of EPDM on Electric Field Distribution of Insulating Interface in HVDC Cable Joints
HVDC cable accessories are an important part of the DC cable system, and it is also the weakness of the cable lines. Due to the difference in conductivity between EPDM and XLPE, the insulating interface space charge accumulates and the field strength increases, resulting in Insulation failure. In this paper, through simulation research, the conductivity parameters of EPDM are adjusted to observe its influence on the electric field distribution at the insulation interface. Based on the simulation results, the guidance for the modification of EPDM materials is put forward.
