XLPE insulation copper power cable

Specifications

Power cable often used to supply power reliably to commercial or residential buildings and to industrial distribution circuits.

Product details

This cable is made by wrapping the conductor with cross-linked polyethylene, which is an insulation material. This is a distribution cable rated for 0.6/1kV to 22.9kV.

What are Medium/Low Voltage Power Cable?
The insulation material of this cable is cross-linked polyethylene, which has a heat-resistance rating up to 90℃. Thus this product is excellent for applications requiring intensive heat resistance. It is categorized as flame retardant, heat-resistant, or environmentally friendly depending on its features.

During last 15-20 years the demand for cross-linked polyethylene insulated cable has expanded rapidly and this type of cable has become the main type for power cables.
SY Cable has actively developed and applied recent manufacturing techniques for XLPE insulated cable, and has been engaged in a constant effort to obtain more stable quality, and produce XLPE cables for higher voltages, exceeding 500kV.
The products in this catalogue are based on the GB/T 12706-2008 or IEC 60502-2004 specification.

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(90℃) as well.

1.Executive standard
As section "Power cable with extruded insulation and their accessories for rated voltages from 1 kV (Um = 1,2 kV) up to 30 kV (Um = 36 kV)" stipulated in GB/T12706-2008 or IEC60502-2004 according to the requirement of the customer .

2.Working Condition
1, Long-term working temperature by cable conductor is 90℃.
2, Max. temperature of cable conductor shall be no more than 250℃ during short circuit (the longest lasting time shall be no more than 5 seconds).
3, Environment temperature for installation is no less than 0℃.
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 Working Condition
