From cables to complete substations
Xinya Power Cables began by manufacturing power cables. Our customers kept asking for the transformer at the other end of the cable — so we added transformers and substations, and now ship both as one package.
About Xinya Power
A power cable manufacturer that delivers complete transformer and substation packages.
Qualified manufacturing
A core team with 30 years of transformer experience, management certified to ISO 9001 / 14001 / 45001, and type tests by a CNAS-accredited national laboratory.

Manufacturing
Built on real production lines — not a trading desk.
Our transformers are built on real production lines: foil and wire winding, vacuum resin casting, oil-filling lines and a full routine-test bay.
Quality & certification
Every unit tested before it ships.
Routine tests on 100% of units, type tests by a CNAS-accredited national laboratory, and a management system certified to ISO 9001, ISO 14001 and ISO 45001.
