What are Line Supports? Definition Types of Line ...

The different types of structure (poles or towers) used for supporting the overhead lines or wires are called line supports. The line support plays a major role in the proper transmission of power. It keeps the proper spacing between the conductors. Line support keeps the conductor at the prescribed distance from its ground parts and also maintained the specified ground clearance.

Overhead power line - Wikipedia

An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances. It consists of one or more uninsulated electrical cables (commonly multiples of three for three-phase power) suspended by towers or poles. Since most of the insulation is provided by the surrounding air, overhead power lines are generally the least costly method of power transmission for large quantities of electric energy.
