Transmission structures are one of the most visible elements of the electric transmission system. They support the conductors used to transport electric power from generation sources to customer load. Transmission lines carry electricity over long distances at high voltages, typically between 115 kV and 765 kV (115,000 volts and 765,000 volts).
There are many different designs for transmission structures. Two common types are:
Lattice Steel Towers (LST), which consist of a steel framework of individual structural components that are bolted or
welded together.
Tubular Steel Poles (TSP), which are hollow steel poles fabricated either as one piece or as several pieces fitted
together.Both LSTs and TSPs can be designed to carry either one or two electrical circuits, referred to as single-circuit and doublecircuit structures (see examples above). Double-circuit structures typically hold the conductors in a vertical or stacked.
configuration, whereas single-circuit structures typically hold the conductors horizontally. Due to the vertical configuration of
the conductors, double-circuit structures are taller than single-circuit structures. On lower voltage lines, structures sometimes
carry more than two circuits.
A single-circuit alternating current (AC) transmission line has three phases. At low voltages, a phase usually consists of one
conductor. At high voltages (over 200 kV), a phase can consist of multiple conductors (bundled) separated by short spacers.
A double-circuit AC transmission line has two sets of three phases.
Dead-end towers are used where a transmission line ends; where the transmission line turns at a large angle; on each side of a major crossing such as a large river, highway, or large valley; or at intervals along straight segments to provide additional support. A dead-end tower differs from a suspension tower in that it is built to be stronger, often has a wider base, and has stronger insulator strings.
Structure sizes vary depending on voltage, topography, span length, and tower type. For example, double-circuit 500-kV LSTs generally range from 150 to over 200 feet tall, and single-circuit 500-kV towers generally range from 80 to 200 feet tall. Double-circuit structures are taller than single-circuit structures because the phases are arranged vertically and the lowest phase must maintain a minimum ground clearance, while the phases are arranged horizontally on single-circuit structures. As voltage increases, the phases must be separated by more distance to prevent any chance of interference or arcing. Thus, higher voltage towers and poles are taller and have wider horizontal cross arms than lower voltage structures.

Solar installations have been rapidly increasing around the world. India has contributed a significant portion of the expansion, and with a target of 500 GW by 2025, it is on the verge of becoming the world’s largest solar nation. Module Mounting Structures are critical to the proper operation of a solar power system, both on the utility grid and the roof. While the most balance of system (SOS) components, including inverters, DC cables, junction boxes, transformers, and so on, are easily available from equipment manufacturers, an EPC contractor’s workmanship is mostly evident through module mounting structures and wiring management. These frameworks allow panels to rest comfortably, avoid damage, and, most significantly, place them at a perfect tilt angle to capture the maximum amount of solar energy. Rooftops, ground mounting, carports, and sun tracker systems all have mounting structures that have evolved in terms of weight, material, versatility, and ease of installation.
