PVC insulated and sheathed power cable standard and parameter data
PVC insulated and sheathed power cable Execution standard
XLPE insulated power cable performance conforms to GB12706.2-1991 equivalent IEC60502-1997, flame retardant performance conforms to GB12666.5-1990 equivalent IEC332-1992. (Not applicable to non-flame retardant cables)
PVC insulated and sheathed power cable Use characteristics
Use characteristics: the rated working voltage of the cable U0/U 0.6/1KV;
Test voltage (duration ≤ 5min) 3.5KV;
Cable conductor long-term working temperature ≤ 70 ° C;
When short circuit (duration ≤ 5s) cable conductor temperature ≤ 160 ° C;
When laying the cable, the smaller bending radius single core cable should be ≥ 10 times the outer diameter of the cable, and the armored cable should be ≥ 12 times the outer diameter of the cable. When the cable is laid, the ambient temperature is ≥ 0 °C. When it is lower than 0 °C, the temperature is pre-heated, and it is not restricted by the drop when laying.
PVC insulated and sheathed power cable Technical indicators
Technical indicators: The DC resistance of the conductor is the same as that of the cross-section cable of the same cross section; the insulation resistance of the finished cable is converted to 20 °C ≥ 36.7 MΩ.km; at room temperature, it is subjected to AC 50Hz, 3.5KV 5min test.
