Steel Wire Armor Swa Armor Electric Power Wire Cable Manufactures

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 volt-age 35 KV or lower. By comparison with power cable with PVC insulation, it has not only excellent electric perfor-mance, mechanical performance, heat & aging resistant performance, weather resistant performance, chemical corrosion resistant performance, but also simple structure,light weight, no restriction by laying drop, and high tem-perature allowance for long term working(90ºC) as well.

Executive standard


As section "extruded insulation power cable with rated voltage from 1kV(Um=1.2 kV)to 35kV (Um=40.5 kV)" stipulated in GB/T12706.1-2002~ GB/ T12706.3-2002 or IEC60502-1997 according to the re-quirement of the customer.

Working Condition

1,Long-term working temperature by cable conducto is 90ºC.

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

3,Environment temperature for installation is no less than 0ºC.

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 U0/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 phrase 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

Type, Description and Application Occasion
Note:1: We also produce steel wire armored cross-linked power cable such as YJV32,YJLV32,YJV33,YJLV33 according to the requirement of the customer.
2: Prefi x "ZR" (flame retardant type) shall be added to the original type when flame retardant type cable is needed.
