Standard of Product
The product is manufactured according to the standard of GB/T12706-2002.At the same time ,it can also be manufactured according to IEC, BS, DIN and AEIC upon request.
Application
The product is suitable for power transmission and distribution lines with rated power frequency voltage 3.6/6kV～26/35kV.
Operating Characteristic
Power frequency rated voltage Uo/U: 3.6/6kV～26/35kV
Max. permissible continuous operating temperature of the conductor: 90℃.
Max. temperature of conductor during short-circuit (5s maximum duration) shall not exceed 250℃.
The ambient temperature under installation should not below 0℃.
The bending radius of a single-core cable: not less than 20 times of cable’s OD
The bending radius of a multi-core cable: not less than 15 times of cable’s.OD
The installation operating condition of cable
Max. permissable continuous operating temperature of the conductor: 90℃.
Ambient air temperature: 40℃.
