6-35kv cross-linked polythene insulated electric cable Middle Voltage 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.
