The HV cable accessories are an important part of cable lines,and their operation quality directly affect the safety of power system.After lead seal cracking on HV cable accessories,the poor grounding of metal sheath leads to the generation of suspension voltage.By analyzing the causes of suspension voltage and its impact on HV cable accessories,the schemes are proposed to eliminate and prevent the generation of suspension voltage in both design and operation,thereby eliminating the impact of suspension voltage.
