Bundled conductors are widely used in High Voltage (HV) and Extra High Voltage (EHV) transmission lines to:
AIncrease mechanical tension
BEliminate skin effect entirely
CReduce conductor weight
DReduce corona loss and line reactance
Explanation
Bundling increases the effective geometric mean radius (GMR) of conductors, reducing electric field intensity at the surface, lowering corona loss, and decreasing inductive reactance.
