Application:
The online transformer oil filtration system is High Vacuum Dielectric Oil Cleaning Plant, Dielectric Oil Recovery Solution, Oil Filtration Plant is special for treating the used and old transformer oil, mutual oil, switch oil. Comparing with the single stage type, this machine adopts the double stages vacuum system, which can improve the machine working vacuum value highly, so it can remove the water, gas and impurities in transformer oil high-efficiently, increasing the pressure force and quality of oil, make sure the electric device running safely.
Features:
1 According to fieldwork requirement, this online transformer oil filtration system equips car wheels, which can be easily moved to any work point by traction. It can be moved kms per hour , which suit to work in wild place.
2 The machine is specially applied to vacuum filling oil and drying for power transmission equipments that are over 110KV.
3 It is especially suitable for purifying transformer oil which locates in fields. This machine can seriously recover transformer oil. The treated transformer oil can reuse again in transformer.
