What is transmission line and its types?

Question

Accepted Answer

Transmission line is a medium that carries electrical energy from one point to another. There are two types: overhead and underground.

Transmission line is used to transmit electrical energy from power plants to substations and then to homes and businesses.
Overhead transmission lines are supported by towers or poles and are visible above ground.
Underground transmission lines are buried underground and are not visible.
Overhead transmission lines are cheaper to install but are more susceptible to damage from weather and other external factors.
Underground transmission lines are more expensive to install but are less susceptible to damage and have less visual impact.
Types of transmission lines include AC (alternating current) and DC (direct current) lines.
AC transmission lines are used for long-distance transmission of electrical energy, while DC transmission lines are used for shorter distances and for transmitting energy between different power systems.
High voltage transmission lines are used for long-distance transmission, while low voltage transmission lines are used for local distribution.
