Transmission towers, also known as transmission towers or transmission line towers, are an important part of the power transmission system and can support and protect overhead power lines. These towers are mainly composed of top frames, lightning arresters, wires, tower bodies, tower legs, etc.

The top frame supports overhead power lines and has various shapes such as cup shape, cat head shape, large shell shape, small shell shape, barrel shape, etc. It can be used for tension towers, linear towers, corner towers, switch towers, terminal towers, and cross towers. . Lightning arresters are usually grounded to dissipate lightning current and reduce the risk of overvoltage caused by lightning strikes. The conductors carry the electrical current and are arranged in a way to minimize energy loss and electromagnetic interference caused by corona discharges.

The tower body is made of steel and connected with bolts to support the entire tower structure and ensure safe distances between conductors, conductors and ground wires, conductors and tower bodies, conductors and the ground or crossing objects.

The tower legs are usually anchored on the concrete ground and connected with anchor bolts. The depth to which the legs are buried in the soil is called the embedding depth of the tower.
