Sheaths for electric cables

This paper proposes a detecting method of the unarmored cable insulation by using DC leakage current, which transforms the synchronous measurement of the cable input-output current into a precise measurement of the input current, so as to simplify the detecting method and enhance the precision of the current measurement.

The armoured single-core cables are used for d. c. system only. As for a. c. system, non-magnetic armour material should be used, or a magnetic isolation shouls beapplied.

*单芯铠装电缆仅用于直流系统，若用于交流系统，应采用非磁性材料铠装或隔磁措施。

Note: A Single-core armoured cable is only applied to DC transmission system. If it is required to use in AC transmission system, non-magnetic materials shall be applied to armoured layer.

注：单芯铠装电缆仅用于直流系统，若用于交流系统，应采用非磁性材料的铠装层。
