The S13 series 10kv oil-immersed transformer designed and produced by our company adopts the structure of fully sealed corrugated oil tank, which is free of maintenance, convenient for maintenance and stable for operation, with remarkable economic benefits.Long service life, maintenance-free operation.The fully sealed transformer box cover and the box edge adopt bolt connection or welded structure to isolate the contact between oil and air, the insulation will not be affected by moisture, greatly reduce the aging rate of insulation, and improve the service life.Compact design structure, low running noise.Because of the use of new materials and new technology, noise reduction, no oil storage tank, the height is lower than similar products.No need to change oil in the normal life period, improve the safety and reliability in operation.

Due to the transformer with corrugated tank full sealed structure, with beautiful appearance, excellent performance, free maintenance and other characteristics, can be widely used in high-rise buildings, commercial center, subway, airport, station, industrial and mining enterprises, drilling platform, production platform, is particularly applicable to flammable, explosive and so on high fire prevention requirements and conditions.
The core:
All adopt high quality grain oriented cold rolled silicon steel sheet, all inclined without hole binding structure, the iron core is multi-step ladder, three or five joints, low void loss, low noise;The coiling iron core is directly wound by special equipment, without joint and Angle weight, which reduces the magnetoresistance and reduces the air loss.
The coil:
It is made of flat copper coin or copper knot made of high quality non-oxygen copper rod, which has the form of circular simple type, continuous type, new spiral type, split type, etc. It has sufficient electrical strength, mechanical strength and heat dissipation ability.
The tank:
Is made of high qualified steel plate welding and become, such as elliptic shape, structure, heat dissipation component adopts chip radiator, expand the radiator or corrugated tank, fuel tank and reliable sealing experiment was carried out in the factory, both inside and outside surface after pickling, phosphating treatment, both inside and outside surface of three times primer, paint spraying again, product has, hot and humid, salt mist prevent mould, beautiful durable, enhance the operation reliability.Adopt corrugated board oil tank, the change of oil volume caused by temperature by the elastic adjustment of corrugated sheet so that the transformer oil and air isolation extended use orders.
Energy saving
Due to the special structure of the core and the annealing process of rolling high quality cold rolled silicon steel sheet with crystal orientation, the no-load loss, no-load current and noise of this series of transformers are reduced by 30%, 70% and 8 db respectively compared with the same capacity S9.
