Technology property
1. Bending dadius:
Bending radius of single core cable is 20(d+D)±5%Bending radius ofmulti-core cable is 15(d+D)±5%D=Aetual outer diameter of cable sample(mm)d=Aetual diameter of the comductor(mm)
2.Installation temperature:
It should be heated where ambient temperature is below ℃
3.leverdifference of cable installation:Not restricted by the difference of level along the route.
