Three Core XLPE Insulated Middle Voltage Power Cable Copper Conductor


XLPE Insulated Electrical Cable For Rated Voltage 3.6/6KV~26/35KV


For XLPE insulated power cable, either chemical method or physical method is employed to transform the molecular structure of PE from chain into three-dimensional network, i.e. thermoplastic PE is transformed into thermosetting XLPE. After cross-linking, the thermal and mechanical properties of PE have been greatly improved while its excellent electrical property are still retained.

The maximum permissible operating temperature of the conductor of a XLPE insulated power cable is 90℃ which resistance is higher than that of PVC or PE insulated power cable. The cable has the advantage of simplicity in construction, lightness in weight, convenience in application besides its excellent electrical, thermal, mechanical and anti-chemical corrosion properties. It can also be laid with no limitation of level difference along the route.

  • Product standard

The product is manufactured according to the standard of GB/T12706-2002 “Extruded solid dielectric power cables for rated voltages from l KV (Um=1.2KV) to 35KV (Um=40.5KV)”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 3.6KV/6KV~26/35KV.

  • Operating characteristics

Rated power-frequency voltage U0/U: 3.6/6KV~26/35KV.

Max. Permissible continuous operating temperature or conductor:90℃.

Max. short-circuit temperature of conductor shall not exceed 250℃. (5s maximum duration)

The ambient temperature under installation should not below 0℃.

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

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.

  • The values of U0 recommended for cables to be used in three-phase systems are listed below.

System category A—This category comprises those systems in which any phase conductor that comes in contact with earth or an earth conductor, is disconnected from the system within 1 min.

System category B—This category comprises those system which under fault conditions, are operated for a short time with one phase earthed. This period should not exceed 1h. For a longer period, not exceeding 8h on any occasion, can be tolerated. The total duration of earth faults in any year should not exceed 125h.

System category C—This category comprises all systems which do not fall into categories A and B.
