Electrical transmission facilities are the backbone of the power grid, responsible for moving electricity from generating stations to local distribution substations. The primary components include:

• transmission lines: The wires (conductors) that carry electricity over long distances. They can be installed overhead on tall towers or underground in specialized conduits.

• Substations: Key hubs in the grid where voltage is transformed—stepped up for long-distance travel and stepped down for local distribution.

• Towers and Poles: The structural supports for overhead transmission lines.

• Switchgear and Transformers: Equipment within substations used to manage voltage, control power flow, and protect the system from faults.

Ningbo Changshi offers a comprehensive array of equipment and tools essential for building and maintaining all these components, ensuring the integrity and reliability of the entire system.
