Question

What is a need of condutors in transmission line?

Answer 1

There are many advantages of using bundled conductors in transmission lines.I am listing some  important factors:

Reduced reactance

reduced corona loss

reduced surge impedance.

Answer 2

$\huge\fbox\pink{♡Answer}$

A conductor is one of the most important components of overhead lines. Selecting a proper type of conductor for overhead lines is as important as selecting economic conductor size and economic transmission voltage. A good conductor should have the following properties: high electrical conductivity.
