ZJA Transformer Oil Filter Machine

  1. Impurities such as water, dust, and particles in the transformer oil will affect the normal operation of the transformer. The purpose of the transformer oil filter machine working is to remove solid particles, free water and sludge from the transformer oil to ensure the cleanliness of the transformer oil and extend the service life of the transformer.
  2. The transformer oil filter machine meets the use of transformer oil with different voltages, multi-stage filtration, high precision of oil filtration, and the obtained transformer oil is purer. Proper use of the oil filter can not only extend the service life of the transformer, save costs, but also contribute to environmental protection.

Application of Transformer Oil Filter Machine 

  • ZJA Series Transformer Oil Filter Plant is used for maintenance of power transformer, it can effectively remove water, gas, and impurities, etc. from the insulation oil of transformer, circuit breakers, mutual inductors, cable and capacitors. It uses a high vacuum system, which is environmentally friendly and safe. It can improve the properties of transformer oil for 33KV to 1000KV.
  • In order to deal with electrical stress, transformer oil is required to have better dielectric strength. The residual water, gas and pollutant content must be kept low to reduce the aging rate of the oil.
  • All these operations are performed using the transformer oil filter machine.
  • The filtration, dehydration and degassing of power transformer oil can be performed individually or simultaneously according to various conditions of the mineral oil and customer requirements.


Features of Transformer Oil Filter Plant 

  1. Suitable for 33kV to 1000kV power transmission voltage
  2. High vacuum, multi-stage filtration, high oil filtering accuracy
  3. Suitable for oil treatment, vacuum oil filling, vacuum pumping
  4. Personalized design
