S□-M Series Dry-type Transformer

S □-M Series Oil-immersed Fully Sealed

The S□ -M series three-phase oil-immersed transformer adopts a fully oil-filled, sealed corrugated oil tank. and the oil tank shell adapts to the expansion performance of the oil with its own elasticity and meets the heat dissipation requirements. It has the characteristics of high efficiency and low loss, which

can save a lot of power consumption and operating costs, and is widely used in power plants, substations, industrial and mining enterprises, ports, airports and other environmental protection places.

Standard: IEC60076-1, IEC60076-2, IEC60076-3, IEC60076-5, IEC60076-10.
