XLPE Insulated (EC)

Standards

  • The XLPE insulated power cable has excellent electrical, mechanical and thermal-aging properties. It has big capacity of transmission. Good resistance to environmental stress and easy to install and maintain, and it has been used in electrical power transmission and distribution systems.
  • The cable is manufactured according to IEC 60502-2004. It is suitable to be installed in the four wire systems with rated voltage of  0.6/1(1.2) ~ 26/ 36/ (40.5) kV (U0/ U/ Um) for transmitting electricity.   

Service characteristics

  • The long-time working temperature of cable should not be higher than 90℃.
  • When core is in short-circuit(max 5S)the temperature should not exceed 250℃.
  • While installation the ambient temperature should not be lower than 0℃, and the bending radius should not be less than 10 times of outer diameter of cable.
  • The AC voltage test of completed cable is tested in accordance with the value specified in and last for 5 minutes.The insulation should not broken down.
