Design of Transmission Tower

The main supporting unit of overhead transmission line is transmission tower. Transmission towers have to carry the heavy transmission conductor at a sufficient safe height from ground. In addition to that all towers have to sustain all kinds of natural calamities. So transmission tower designing is an important engineering job where all three basic engineering concepts, civil, mechanical and electrical engineering concepts are equally applicable.

A power transmission tower consists of the following parts,

1) Peak of transmission tower

2) Cross arm of transmission tower

3) Boom of transmission tower

4) Cage of transmission tower

5) Transmission Tower Body

6) Leg of transmission tower

7) Stub/Anchor Bolt and Base plate assembly of transmission tower.
