Q. What are the types of transmission line towers?

Question

Accepted Answer

There are mainly four types of transmission line towers: suspension, tension, angle, and dead-end towers.

Suspension towers are used to support the high voltage transmission lines over a long span.
Tension towers are used to support the high voltage transmission lines when the line changes its direction.
Angle towers are used to support the high voltage transmission lines when the line changes its direction at an angle.
Dead-end towers are used to support the high voltage transmission lines at the end of the line.
The type of tower used depends on the voltage level, terrain, and span of the transmission line.
For example, suspension towers are used for long spans over valleys and rivers, while angle towers are used for sharp turns in the transmission line.
