bending radius should be 12 to 15 times of the cable diameter.
for XLPE cable 12 times of dia.
for PILC cable 15 times of dia.

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened. Why does the strand conductor of Electrical power transmission line make twist?
