The cable is manufactured according to GB /12706-2008 or IEC 502-2004.
It is suitable to be installed in the four wire systems with rated voltage of 0.6/1kv (Uo/U) for transmitting electricity.
The ling-time working temperature of cable should not be higher than 70℃.
When core is in short-circuit(max 5S)the temperature should not exceed 160℃.
While installation the ambient temperature should not be lower than 0℃, and the bending radius should not be less than 10 times of outer diameter of cable.
Cable armour specification
|Steel tape layer × thickness
(not less than)
|Fine steel wire diameter
|Thick steel wire diameter
The assumed diameter only used for determinig the size of each sheath layer of cable. It is not the actual diameter. The Calculation methods of assuemd diameter see IEC 60502-2004
