S□-M Series 10kV Oil-immersed Transformer

The 10kV oil-immersed transformer produced by Hezong Technology adopts domestic high-quality high-permeability silicon steel strip material, and the iron core is a 45-degree fully inclined joint structure, which makes the magnetic circuit evenly distributed and greatly reduces no-load excitation current and no-load loss; The transformer windings are made of high-quality pure copper, with high and low voltage windings wound together, compact structure, small size and light weight. The transformer has reliable operation, low noise, good manufacturability, good heat dissipation, low temperature rise, no pollution to the environment, no maintenance, and high efficiency. It is mainly used in 10kV power transmission and distribution system, and can be widely used in residential areas, commercial streets, industrial and mining enterprises and rural power and lighting, commercial centers, subways, airports, stations, industrial and mining enterprises, drilling and oil production platforms and other places.
