Working characteristics of power cable

    The rated voltage U0 / u is 0.6/1 (1.2) kV;
    The maximum allowable working temperature of conductor for a long time is 90 ℃ for XLPE insulation and 70 ℃ for PVC insulation;
    Withstand voltage level
        When U0 / u is 0.6/1 (1.2) kV: 2.5 U0 + 2KV / 5min without breakdown (or 3500v / 5min without breakdown).
    Partial discharge test
        The partial discharge of the cable at 1.73 U0 is not more than 10pc。
