Tower line construction refers to the civil and structural development of transmission line towers that carry high-voltage electricity across long distances. These towers are essential for the power transmission grid, enabling efficient and safe delivery of electricity from power plants to substations and end-users.
At Bhagavathi Construction, we specialize in the civil works, foundation engineering, and site preparation required for the erection of electric transmission towers, including 66kV to 765kV lines.
Types of Transmission Towers
Self-Supporting Lattice Towers
- Made of steel lattice structures.
- Common for high-voltage lines (220kV and above).
Guyed Towers
- Supported by guy wires.
- Economical but require more space.
Monopole Towers
- Single steel pole design
