Technology Property

1. Bending radius: Bending radius of single core cable is 20(d+D)±5%,Bending radius of multi-core cable is 15(d+D)±5%,D=Actual outer diameter of cable sample(mm),d=Actual diameter of the conductor(mm).
2. It should be heated when the temperature is below 0℃ level difference of cable installation.
3. Not restricted be the difference of level along the rout.
4. Conversion Factors of Current Rating for Ambient Temperature.
