摘　　要：简述了线路运行中单芯高压电缆金属护套感应电压规定值在国内外有所不同及变化情况,指出了修改后的国家标准GB50217—2007《电力工程电缆设计规范》,将原规定的100V提升到300V后的积极意义,以及由此引起的相关问题的讨论。In this paper, different specified induction voltages and the variation of the induction voltages in the metal sheath of single core HV metal sheathed cable in operation in China and foreign countries are identified. The positive significance of the fact that the specified induction voltage was increased from the original value of 100 V to 300 V in the revised GB 50217-2007 Specification of the design of the cables for electrical Engineering was indicated and related discussions were presented.
