The rated voltage U0/U is 500V, 750V, 1KV, 1.5KV and 3KV. The rated DC voltage is 1.5 times the rated AC voltage.
Long-term allowable working temperature of wire and cable: 125 product is 125 C; 150 product is 150 C.
Minimum ambient temperature of cables: non-B-40 C; B-60 C.
Permissible bending radius for laying wires and cables:
Cable outer diameter (D) should be no less than 3-D when 20 mm or less.
When the outer diameter (D) of the cable is more than 20 mm, it should be no less than 5 D.
WDZ-DCYJ-125 cable can be used in oil contaminated environment; WDZ-DCYJ/B-125, WDZ-DCYJ/B-150 cable can be used in harsh environment with various kinds of grease contamination and non-high concentration acid-base contamination.
Insulation Resistance at 20 C: The rated voltage of WDZ-DCYJ-125, WDZ-DCYJ/B-125 and WDZ-DCYJ/B-150 cables should be no less than 1010_.km.
