Cable brief Structure









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

·

Rated power-frepuency voltage U0/U: 3.6/6kv~26/35kv.

Max.admissible operating temperature of the conductor:90℃.

Max. short-circurt temperature of conductor shall not exceed 2500C.

(5s maximum duration)

The ambient temperature under installation should not below 00C.

The bending radius of a single-core cable should not less than 20 times of the cable diameter.

The bending radius of a single-core cable should not less than 15 times of the cable diameter.


Voltage designation

The rated voltage of the cable for a given applixation 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 conductors and earth metallic screen ,for which the cable designed;

U - The rated power-frequency voltage between conductos, for which the cable designed;

Um- The maximum value of the[highest system voltage"for which the equipment may beused.

The values of U0 recommened for cable to be used in three-phase systems are listed below:
