Product Description

Medium voltage xlpe power cable:

1 Product Standard
This product is manufactured according to GB/T12706.2, equivalent to IEC60502.2. Or BS, DIN, ICEA standard as customer request.
2 Application
The product is suitable for use in power transmission and distribution lines with rated power frequency voltage 3.6/6kv~26/35kv.
3 Operating characteristics
– Rated power-frepuency voltage U0/U: 3.6/6kv~26/35kv.
– Max.admissible operating temperature of the conductor:90ºC.
– Max. short-circurt temperature of conductor shall not exceed 2500C. (5s maximum duration)
– The ambient temperature under installation should not below 00C.
– The bending radius of a single-core cable should not less than 20 times of the cable diameter.
The bending radius of a multi-core cable should not less than 15 times of the cable diameter.

The cable with Category A rated voltage is used in the situation requiring not over 1 min. of grounding fault lasting time. For the cable with Category B rated voltage, the grounding fault lasting time normally is not over 1 hour, max. lasting time is not over 8 hours, annual ground fault lasting time altogether should not be over 125 hours, Category C includes all the system expect Category A and B.
