To handle electrical stresses, transformer oils are required to have better dielectric strength. Lower residual water, gas and contamination content must be maintained to reduce the speed of oil ageing. All of these operations are performed using the transformer oil filtration equipment.

ASSEN ZYD transformer oil filtration, dehydrating and degassing can be performed individually or simultaneously based on the various conditions of the mineral oil and customer requirements.

1.Based on the high efficient vacuum oil filtration, roots vacuum booster system and secondary high vacuum separation system are added. Which enable the vacuum limit reaching ≤5pa.
2.Being able to remove water and gas and effectively under high vacuum and high speed operation status ,which achieves satisfactory dryness and could bring the breakdown voltage up to reduces the oil aging problem existing with ordinary purifier as caused by repeated heating.
3.Distinctive removing impurities technology filtering through double FH trapezoidal network and absorbing by high polymer without the mechanical power.
4.The advanced infrared level automatic control system. interlocking control foe pressure protection and power heating system ensure long-term safe and reliable operation.
5.Mobile equipment for outdoor use.
6.Live-line vacuum oiling and dehydrating feasible.

Oil filtration 's Technical Data:

Structure Chart:
 

The oil technical data after treatment:

• Gas content less than 0.1%
• Impurity size less than 1μm without free carbon
• Oil dielectric strength (breakdown voltage) more than 75KV
• Acidity value less than 0.01 mgKOH/g
• Dielectric loss factors at 90°C less than 0.001

Oil filtration's Advantage:

1.The conventional process of transformer oil exchange is time consuming, costly and not environmentally friendly.  
2.Our mobile oil purification plants can regenerate the oil on site and in most cases while the transformer is online. This means there will be no production outages for you.  
3.It will also be 30 to 60% cheaper to purify the transformer oil compared to exchanging the oil.
4.The process of oil purification not only restores the oil properties, but also cleans the inside of the transformer of all decay products, which would not happen if the oil was merely replaced.

Q: How can we achieve drying without elevated heating of the insulation material for transformers?
A: Drying of insulation materials can be achieved at low temperature and low pressure levels. The pressure levels and temperature levels for drying vary for distinct material. At low pressure or under vacuum the rate of water vapour evaporation is accelerated if sufficient heat is provided to the insulation material. Thus we can achieve a good drying of insulating material if the material is suitably heated and subjected to vacuum.
