Power line support structures, often referred to as poles or towers, are designed to hold conductors at a safe distance from the ground and other structures. The main types are categorized by their function and design:

• Suspension Towers: These are the most common type and are used for straight sections of a power line. They simply "suspend" the conductors. They are designed to primarily support the vertical weight of the conductors and insulators.

• Tension/Strain Towers: These towers are built to handle the horizontal tension of the conductors. They are used at angles in the line, at dead ends, or at crossings over major obstacles like rivers or roads.

• Transposition Towers: These are specialized towers used to change the relative position of the conductors on the line to balance electrical properties and improve system efficiency.

• Dead-End Towers: A type of tension tower, these are used at the very end of a transmission line, such as before a substation or when the line transitions to an underground cable. They are designed to withstand the full tension of the conductors in one direction.

We provide a comprehensive range of tools and equipment to support the construction and maintenance of all these tower types. Our OHTL tension stringing equipment, for example, is essential for safely installing and tensioning the conductors that these structures support.
