why do we use bundle conductors instead of using single
conductor of larger size for high voltage transmission?
Answer Posted / amit kumar beniwal
In AC transmission line if conductor Diameter increase then
Skin effect increase due to high concentration of current
near outer surface of the conductor & due to this cause
Corona loss also increase.SO we use bundle conductors
instead of single conductor.
BUNDLE CONDUCTOR -When we combine number of conductors as a
conductor whose Diameter is small is called Bundle conductor.
CORONA LOSS-Hissing noise & luminous glow due to high
voltage ionises nearby air which cause power loss and also
effect communication signals.
