Our S11/S13/S15/S20-M series fully sealed oil-immersed power transformer developed and produced by our our company has the advantages of low loss, low noise and high efficiency, which can achieve good energy-saving effect and reduce pollution. Fully sealed transformer and ordinary oil-immersed transformer, compared with the elimination of the oil storage cabinet, oil volume changes by the corrugated oil tank corrugated sheet of the elasticity to automatically adjust the compensation, the transformer is isolated from the air, to prevent and slow down the deterioration of the oil and the aging of the insulation, enhance the reliability of the operation, the normal operation of maintenance-free.

Our the iron core of S13-M series low loss energy-saving transformer produced by our company adopts laminated structure. This product is based on fully absorbing the advanced technology and process of domestic oil immersed transformer, combined with the technical level of our company, putting the reliability of the product in the first place, at the same time, the no-load loss and no-load current of the product are greatly reduced.
Features
1. The coil adopts a low axial short-circuit force structure. When the transformer is short-circuited, it can greatly reduce the axial short-circuit force and greatly improve the ability of withstanding short-circuit.
2. All the bolts and nuts on the cover surface are made of 304 stainless steel, which enhances the rust prevention ability of the transformer.
3. Each sealing rubber ring adopts the best rubber material in China, which greatly prolongs the service life of the sealing rubber ring.
4. The transformer body adopts a high-reliability support structure to ensure reliable compression of the upper and lower parts of the coil. The entire body structure improves the ability of withstanding short-circuited.
5. This not only reduces the no-load loss of the transformer, but also ensures that the core flux is not saturated when the transformer is operating under voltage, so that the third harmonic of the transformer is small.
