35 kV or Lower Power Cable with XLPE Insulation

The cable is used to transmit power on the power transmission and distribution line of A. C, 50Hz, rated voltage 35 kv or lower, By comparison with power cable with PVC insulation, it has not only excellent electric performance, mechanical performance, heat & aging resistant performance, weather resistan performance, chemical corrosion resistan performance, but also simple structure, light weight, no restriction by laying drop, and high temperature allowance for long term working (90º C)as well.

Executive standard

As section "extruded insulation power cable with rated voltage from 1kV(Um=1.2kV) to 35kV (Um=40.5kV)"stipulated in GB/T12706.1-2008~GB/T12706.3-2008 or IEC60502 according to the requirement of the customer.

Working Condition

1. Long-term working temperature by cable conductor is 90º C.

2. Max temperature of cable conductor shall be no more than 250º C during short circuit (the longest lasting time shall be no more than 5 seconds).

3. Environment temperature for installation is no less than 0º C.

4. Min bending radium of cable:

It is no less than 15 times that of cable outer diameter for cable with three cores.

It is no less than 20 times that of cable outer diameter for cable with single core.

5. A. C. Rated voltage of Uo/U of cable is 0.6/1kV~26/35kV.

U0: Rated A. C. Voltage of conductor to earth OR between metallic shielding for cable designing, which is called phase voltage.

U: Rated A. C voltage between conductors for cable designing, which is called wire voltage.

Um: Max endurable value of "Max system voltage" for cable.
