Transformer oil is used to suppress arcs at the high-voltage leads and tap-changer contact points to prevent corona and arc discharge, and also to insulate and maintain the windings (maintain good insulation).

If the transformer oil contains moisture, its insulation and arc suppression function will be affected, and the transformer oil cannot be cooled better. Therefore, if the transformer oil produces moisture after use, it can no longer be used, so it is quite wasteful to sell the replaced oil to sell waste oil, and the dehydration of transformer oil becomes very important.

Most people who don't know vacuum oil filter equipment will directly sell the replaced waste transformer oil to others, and then buy new transformer oil. They don't know that this wastes resources and greatly increases costs.
Therefore, we have Yuneng oil purifier specially designed for transformer oil dehydration and degassing. The dehydration technology of the oil purifier uses a decompression separation, three-dimensional three-dimensional flash rapid evaporation system. Under the high vacuum state, the evaporation speed of the oil is fast and the efficiency is high, and it also ensures that the additives in the oil are not affected by the heating temperature and cause secondary damage. The ultimate withstand voltage value of transformer oil after dehydration, degassing, deacidification and free carbon removal using a two-stage vacuum oil filter is higher.

The vacuum oil purifier can be used for oil filtration, and can also be used for vacuum drying and oil filling of transformer equipment.

Transformer oil dehydration can effectively filter out 100% of free water and 99.9% of dissolved water in the oil, as well as 100% of free gas and 98% of dissolved gas.
