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。
