Putting aside the electric strength of the transformer oil or insulating liquid in a transformer, it is important that the liquid is maintained so that the integrity of the core transformer components are retained. Key to this is the paper insulation and cellulose. The combination of heat, moisture and oxidisation has a detrimental effect on the paper and it’s mechanical strength.
Maintaining the mechanical strength of the paper is the key to extending the lifespan of a transformer. The rising commodity prices of the metals and materials used in building or restoring a transformer, and the cost of installation make the proper maintenance, and extension of the working life, of the transformer all the more important.
During the normal operation of the transformer, along with the expansion and contraction caused by the power load, moisture and contaminants resulting from oxidisation will build up in the oil and are transferred to the paper. These contaminants have the detrimental effect on the core.
Treating the transformer oil, or insulating liquid, cannot reverse the damage to the insulation paper and cellulose, but it can significantly reduce the aging process, thereby extending the lifespan of the transformer.
One of our best selling products - "ZYD Series Double-Stage High Vacuum Transformer Oil Purifier", is specially used for treating transformer oil, easy operation, high reliability.
