Product Description

Oil immersed transformer


1.Product Description

With capacity from 30KVA to 1,600KVA, the three-phase 10kv oil-immersed transformer is made under advanced production technology.

It is designed by corrugated plate instead of oil storage tank, thus oil is placed apart from the outside world. In addition, the coil and iron core are treated by vacuum-drying. All these features aim to get better insulation performance. In return, the transformer does not need to change oil in long term operation. Low maintenance cost, extended service life.

Structural Features

  • The low-voltage winding of an oil immersed transformer, except for copper conductor used for small capacity transformer, generally adopts copper foil winding and extraction hydro-cylinder structure; and the high-voltage winding adopts multi-layer barrel structure. These result in evenly distributed ampere-turns, small magnetic flux leakage, highmechanical strength andstrong short-circuit resistance.
  • The iron core and windingare fastened separately. The machine height, low-voltage lead and other fastening parts adopt self-locking locknut and non-suspension structure, which can withstand impact during transportation.
  • The coil and iron core are treated by vacuum-drying, and the transformer oil is filtered and oiled in vacuum to reduce the water content inside of the transformer.
  • The oil tank is made of corrugated plate, which could absorb oil to compensate temperature fluctuation caused by oil volume change. Therefore, this product has no external oil tank, which significantly reducesheight of the transformer.
  • As the corrugated plate replaces the oil storage tank, the transformer oil is isolated from the outside world, effectively preventing entry of oxygen and water and resulting in the decrease of insulation performance.
  • The above five performances enables the oil immersed transformer no need to change oil in normal operation, greatly reducing the maintenance cost , and extending the service life of the transformer.
