摘　　要：高压电力电缆具有故障率低、对环境影响小等特点,在现代城市电力发展中占据重要一环。近年来,随着高压电力电缆迅速发展,电缆体量猛增,由于质量把控下降等原因造成电缆故障逐渐增多。以单芯高压电力电缆外护套故障为例,结合实际生产工作,分析了不同程度外护套故障的修复方法,并探寻了聚四氟乙烯在外护套修复工作中的可行性。High-voltage cable has the characteristics of low fault rate and little impact on the environment.Therefore,it plays an important role in the electric power development.In recent years,with the rapid development of high-voltage cable,the quantity of cables has increased sharply.Beacause of the quality control decreasing,cable faults have gradually increased.Taking the high-voltage cable sheath fault as an example,combined with the actual production,it analyzes the repair methods of different degrees of cable sheath fault and explores the feasibility of PTFE(polytetrafluoroethylene)in the repair of cable sheath.
