Electric transmission tower is the steel frame used to carry conductors, ground wires, and insulator strings over long distances. It keeps the line at a safe height and transfers load from wire weight, wind, ice, and tension into the foundation.
The tower is usually designed after route survey and line calculation. Height, arm length, tower head shape, bolt grade, and foundation type all affect the final drawing. For coastal or wet areas, hot-dip galvanizing with extra coating can be selected after the corrosion level is checked.

Product Advantages
The electric transmission tower is made from many checked members, so every hole and plate position matters.
1. Prefabricated steel members help reduce site welding work.
2. Tower shape can be changed for route angle and conductor layout.
3. Inspection before packing reduces missing-part problems on site.
Main Applications
An electric transmission tower is used in overhead line projects where stable wire support is needed.
1. Distribution and high-voltage transmission routes.
2. Power line crossing sections near roads or rivers.
3. Substation incoming and outgoing line structures.
4. Upgrade projects that need stronger tower load data.
Our Services
Tengshida can discuss drawing size, wind load, surface finish, packing method, and loading plan before production. For site projects, the work can also include drawing review, material confirmation, factory inspection photos, and basic installation notes.
FAQ
Q: Can it be designed for coastal areas?
A: Yes. An electric transmission tower can use hot-dip galvanizing plus paint after corrosion grade is checked.
Q: What data is needed before design?
A: Voltage, conductor type, span, wind, ice, route angle, foundation condition, and local rules are needed.
Q: How long does site assembly take?
A: It depends on height and foundation. A 40 m tower section may take about 7-10 days after basic conditions are ready.
