AlphaTND is a leading EPC contractor for transmission projects and have completed many challenging projects in West Africa. Transmission and Distribution Sub-stations are important nodal points in the distribution of power to various geographical zones and areas of Electrical Network. Power is evacuated and transmitted from Generating Stations at high and extra high voltages (132kV, 161kV and 330KV) along the National Grid Transmission Lines.

The Transmission Sub-stations are located at strategic nodes on the route, where the high voltages are stepped down to Medium level voltage, typically 33KV, for transmission to relatively shorter distances in urban and rural areas.
