Features of Products
The three-phase oil-immersed distribution transformer produced by our company uses a new insulating structure to improve the ability to withstand short-circuits. The iron core is made of high-quality cold-rolled silicon steel sheet, and the windings are made of multilayer cylinder or foil structure. All of fasteners use special anti-loose treatment.The product has the characteristics of high efficiency and low loss. It can save a lot of power consumption and operating costs and also has significant social benefits. It is the national high-tech products.
