A power grid consists of four main stages, each with its own voltage levels:

1. Generation: Power plants generate electricity at relatively low voltages, typically from 11 kV to 33 kV.

2. Transmission: The voltage is stepped up to very high levels (132 kV to 765 kV) for efficient long-distance transport via transmission towers and lines.

3. Sub-transmission/Primary Distribution: The voltage is stepped down to medium levels (e.g., 33 kV, 66 kV) to move power closer to populated areas.

4. Distribution: Finally, the voltage is reduced to low levels (e.g., 220V, 400V) for safe use in homes, commercial buildings, and factories.

Our comprehensive product line, including Overhead Transmission line equipment and underground cable laying Equipment, supports every stage of this process, from initial construction to ongoing maintenance. We provide a one-stop supply for all the tools needed to build and maintain a reliable and efficient power grid.
