A lattice transmission tower, also known as a lattice tower or a transmission lattice tower, is a tall and slender structure used to support overhead power transmission lines. These towers are typically made of steel or reinforced concrete, and feature a lattice-like structure that provides excellent strength-to-weight ratio, making them capable of withstanding extreme weather conditions and heavy loads.

The lattice design of these towers allows for efficient use of materials, as well as ease of construction and maintenance. The towers are often used in remote or hard-to-reach areas where access to heavy machinery and equipment is limited. They are also commonly used in urban areas where space is limited, as the slender design of the lattice towers takes up less ground space compared to other types of transmission towers.

Lattice transmission towers are a critical component of modern power grids, as they enable the efficient and reliable transmission of electricity over long distances.
