The 10 kV oil‑immersed transformer is the most widely‑applied core medium‑voltage distribution equipment in China, with a maximum system voltage of 12 kV. Designed and manufactured strictly in accordance with GB1094, GB/T6451, IEC 60076 and other standards, it uses transformer oil as insulation and cooling medium and adopts a three‑phase two‑winding structure. It is mainly used for voltage conversion and power distribution in 10 kV distribution networks, and is suitable for various terminal power‑supply scenarios including industry, municipal works, rural areas and industrial parks.

The 10 kV rectifier transformer is a special‑purpose transformer with a rated high‑side input voltage of 10 kV. Specially designed for rectifier assemblies, its primary side is connected to the 10 kV industrial power grid, and the secondary side outputs multiple sets of low‑voltage AC, which is converted into DC power by rectifier cabinets. Unlike ordinary distribution transformers, it can withstand pulsating current and harmonic surges generated by rectifier loads, and is widely used in various industrial DC power‑supply scenarios.
