Scope of application:
It is suitable for the maintenance of facilities above 110KV, the maintenance of the best deteriorated transformer oil, insulation oil, and the need to restore the acid-base water solubility index and improve the recovery of the oil color of the insulation oil. It is commonly used for vacuum filtration treatment of more valuable oils such as transformer oil, new oil, imported oil, transformer oil and transformer system capacitor oil and refrigerated oil, and can also be used for vacuum oiling and drying of transformers.
