Abstract
Due to single-point and multi-point grounding of the shield of the 35 kV single-core cable, induced voltage is generated and convective current formed in the shielding layer, which heats the cable, accelerates aging of the cable and even forms high induced volt-age to breakdown the outer sheath of the cable. To solve this problem, the shielding of long-distance 35 kV single-core cable was cross connected, effectively reducing induced volt-age and ensuring safe and stable operation of the cables.关键词
