The application
It adopts the sealing structure of corrugated oil tank, with beautiful appearance, excellent performance and maintenanceless features. It can be widely used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, oil drilling platforms and oil extraction platforms. It is especially suitable for inflammable, explosive and other places with high fire protection requirements and bad environment.
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 joints or five joints
Coil
The coil 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.
Fuel 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, after pickling, phosphating treatment, internal and external surface to paint spraying, four products have, hot and humid, salt mist prevent mould, beautiful and durable;Adopt corrugated board oil tank, the temperature caused by the transformer oil volume change by the elastic adjustment of the corrugated sheet so that the transformer oil and air isolation extended use orders.
Energy saving
Due to the special structure of the iron core, which is formed by annealing of high quality cold rolled silicon steel sheet with crystal orientation, the no-load loss is reduced by 30%, the no-load current by 70% and the noise by about 8 db compared with the same capacity S9.
