Product Description

33kV 250kva electric transformer S9 S11 voltage transformer3 Phase oil immersed power electric Current transformer price


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.

2.Main Functions And Features

-High reliability, advances level of performances, reasonable economical indicators.

-The core joints are of stepped shape with 3 steps, and the surface of the core is coated with cured paint to lower losses and noise.

-The winding has novel structure and its oil passage is reasonable designed. Its newly designed insulation structure helps enhance its mechanical strength and the short circuit withstanding ability.

-The oil tank is in various types, all have good outlook.
