Transmission Line.
Overhead lines from 66 kV to 765 kV. Every span, clearance and structure load has to hold across the real terrain.
Types We Engineer.
No two Transmission Line Projects are the same. Here is what changes from one type to the next.
66 kV to 132 kV
Sub-transmission lines between grid and distribution substations.
What We Focus On- Pole or lattice structures
- Clearances in built-up areas
220 kV to 400 kV
Main transmission lines between grid substations.
What We Focus On- Lattice tower design
- Insulation coordination and lightning performance
765 kV
The highest AC transmission class in India.
What We Focus On- Large-tower structural design
- Corona, interference and clearances
