Product Introduction:

S-M series three-phase oil-immersed transformer adopts fully oil-immersed sealed corrugated tank. The tank shell itself uses the elasticity to meet the expansion characteristics of oil, and meets the heat dissipation at the same time. The tank body adopts new insulation structure, which improves short-circuit withstand performance; High-quality cold-rolled silicon steel sheets are used in the core; The high-voltage and low-voltage windings use oxygen-free copper wire and adopt a multi-layered cylindrical structure; All fasteners are treated with special anti-loosening. This product features high efficiency and low loss, significantly saving energy and operating costs, resulting in significant social benefits. It is widely used in power plants, substations, industrial and mining enterprises, ports, airports and other places.
