摘　　要：电缆外护套试验,是衡量电缆健康状况的重要指标,是电缆运维部门有针对性地运行、检修工作的重要依据。按照相关标准规定,橡塑绝缘电缆外护套试验,重要电缆试验周期为一年,一般3.6 k V/6 k V及以上电缆试验周期为3年。该文简要叙述了单芯电缆外护套绝缘良好的重要性,结合110 k V海机线外护套绝缘电阻测试、故障查找对绝缘电阻不达标的几点原因进行分析。Cable outer sheath test,is an important indicator of how healthy your cable,cable operations is the important basis of targeted operation,maintenance and repair work.In accordance with the"power equipment preventive test code"regulation,rubber insulated cable outer sheath test,cable test cycle is one year,more than general up to and including3.6kV/6kV cable test period is3years.This paper briefly describes the importance of the single core cable outer sheath insulation good,combined with110kV sea machine line outer sheath insulation resistance testing,troubleshooting to analyze several reasons substandard insulation resistance.
