Executive standard
As section 《extrusion insulated power cable & accessories rated voltage 1KV 1KV（Um=1.2KV）-35KV（Um=40.5KV）》in GB/T12706.1～12706.4～2002 or IEC60502-1997. 

Feature:
1. Environment temperature should be no lower than 0℃ for laying the cable, otherwise the cable should be pre-heated.
2. The minimun cable bending radius is stipulated as follows: 
Single core: 20（d+D）±5%; 3 cores: 15（d+D）±5%; (D for actual cable outer diameter, d for that of conductor) The highest rated temperature of the conductor is 90℃, no higher than 250℃ in time of short circuit (lasting no longer than 5 seconds)

Cable Model, Name and Application Occasion

Remarks:  We may produce the cable with steel wire armor structure as user’s dmand, for example YJV32, YJLV32 types, etc.
                    Code prefix:”ZR-” should be added to the original code in ordering on flame-retardant cable.

Cable Rated Voltage, Cross-section Core Number

Cable Length: 
It should be generally no shorter than 100 meters per piece. The cable no shorter than 30 meters is allowed for delivery, which accounts for no more than 10% of the total. It depends on final both agreements with length error of no more than ±0.5%.
