Application:
Ultra high voltage has the advantages of big capacity, long distance and low loss during transmission, so it has extremely high requirements for insulating oil in transformers, mutual inductors and reactors. Our ZUD High Voltage Oil Filtration Plant applies to maintenance of transformers above 110KV-750KV and deep purification of high grade new transformer oil, and ultra high voltage transformer oil. It can be also used for oil vacuum filling and vacuum drying as well as transformer vacuum evacuation operation.
