instead of straight?

why is the core of the underground cable is spiral in shape instead of straight?..

Answer / shahin

Rolling is one of the fact....
But the main reason for spiral is mechanical.
In straight wire the share force is less than that of
spiral wire. hance the spiral wire's strength is too much
higher than straight wire.......this is the main fact....

Answer / phani

If it is spiral , the electrical losses are less ( i don't
know exact losses but i can confirm that it is not for easy
to rolling)

why is the core of the underground cable is spiral in shape instead of straight?..

Answer / ashok bhatnagar

The spiraling is done to transpose the three phase current
carrying conductors. This results in near zero net magnetic
field produced by the cable. This is required to minimise
electrical interference to other naerby cables.

why is the core of the underground cable is spiral in shape instead of straight?..

Answer / kishor bankar

Under ground cable should be in spiral in shape
insteed of straight,because in staight position there is
formation of capacitance,so charge will develop on core,
due to this cable will be heated.
Also to avoid transposition effect cable should be
run in straight shape in underground.
