35KV Cross-linked polyethylene(xlpe)insulating power cable

Product Description:

Standard:
 The product is manufactured according to the standard of GB12706 or IEC, BS, DIN and ICEA upon request.
 
 Applications:
 The product is suitable for use in power transmission and distribution lines with rated power frequency voltage 3.6/6kV-26/35kV.
 
 Operating characteristics:
   1、Rated power-frequency voltage U0/U: 3.6/6kV-26/35kV.
 2、Max. Permissible continuous operating temperature of conductor: 90℃.
 3、Max. short-circurt temperature of conductor shall not exceed 250℃.　(5s maximum duration) .
 4、The ambient temperature under installation should not below 0℃.
 5、The bending radius of a single-core cable should not less than 20 times of the cable diameter.
　 The bending radius of a three-core cable should not less than 15 times of the cable diameter.
 
 Voltage designation:
 1、The rated voltage of the cable for a given application shall be suitable for the operating
 conditions in the system in which the cable is used, and is expressed in the form of U0/U(Um)kV.
 Where:
 　U0--The rated power-frequency voltage between conductor and earth or metallic screen, for
which the cable designed;
　U --The rated power-frequency voltage between conductors, for which the cable designed;
　Um--The maximum value of the "highest system voltage" for which the equipment may be used.
