Substations are the hubs of the electrical grid, and transformers are the key devices within them.

• Step-up Transformers: Located at or near power plants, these transformers increase the voltage of the generated electricity to a high level for efficient long-distance transmission.

• Step-down Transformers: Situated at local distribution substations, these transformers reduce the voltage to a lower, safer level that can be delivered to communities and eventually to individual buildings.

Ningbo Changshi manufactures and exports the specialized tools required for the construction and maintenance of these vital components, ensuring the grid operates reliably and safely.
