Power transmission and distribution line towers are used for transmission of electric energy from the power plants to the transformer stations in proximity of the electric consumption areas or the distribution there of from these stations to end-users.
These structures are designed and manufactured considering the parameters such as routes of the transmission/distribution lines, geography, land and atmospheric conditions, line voltages, carrying capacity and intended use as specified below.
- Suspension/Tangent Towers: These are the towers that are only intended to carry the conductors and that are used in the linear routes or small angled corners, where the conductors are bound with suspension insulator.
- Tension/Angle Towers: These are the towers that are intended to carry the line conductors and fix the same with a tension insulator and that are used in the linear route or corners.
- Crossing Towers: These are the towers that are specially designed for the locations, where a significant level of traffic prevails, such as highways, watercourses or railways or long distance river/sea crossings.
- Terminal/Dead End Towers: These are the towers that are used at the beginning or end of the lines for terminating the transmission line purposes.
Power Transmission & Distribution towers and poles are manufactured in the lattice and polygonal types up to 1200 kV and, delivered as galvanized and/or painted.
