Explanation:
Detailed explanation-1: -Transmission lines carry electric energy from one point to another in an electric power system. They can carry alternating current or direct current or a system can be a combination of both. Also, electric current can be carried by either overhead or underground lines.
Detailed explanation-2: -The transmission lines which have more than one conductor are called as Multi-conductor lines. Co-axial Lines. This one is mostly used for high frequency applications. A coaxial line consists of an inner conductor with inner diameter d, and then a concentric cylindrical insulating material, around it.
