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.
