3.6 / 6KV Medium Voltage PVC Sheathed Steel Wire Armored Electric Power Cable

3.6 / 6KV ?Medium Voltage PVC Sheathed Steel Wire Armored Electric Power Cable

1.Product standard
GB/T12706-2002 (IEC60502-1983)

?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°C.

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

??? The ambient temperature under installation should not below 0°C.

??? 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.
