Frequently asked

What is the highest voltage in China?

China operates 1000 kV UHV AC and ±800 kV UHV DC — the highest voltage classes in commercial service — with 750 kV and 500 kV feeding regional networks.

Who are the main grid operators?

State Grid Corporation of China (SGCC) covers most of the country; China Southern Grid (CSG) covers the southern provinces.

Is China a major exporter of transformers?

Yes — Chinese OEMs are the largest global source of power and distribution transformers and many component categories, which is why they appear across TransformerPath country pages.
