why do we use bundle conductors instead of using single
conductor of larger size for high voltage transmission?

Answer Posted / vikalp dhiman

Extreme High Voltage carrying lines causes corona loss.to reduce this loss we use bundled conductors.These consists of 2,3,or many more conductors in bundle.Each conductor carries equally distributed among these conductors(in bundle).Due to this corona loss reduces
CORONA LOSS--High voltages ionises nearby air which causes power loss and affects communication wires.
