Transformer Oils

Transformer oil is a highly-refined mineral oil that is stable at high temperatures and has excellent electrical insulating properties. It is used in oil-filled transformers, some types of high voltage capacitors, fluorescent lamp ballasts, and some types of high voltage switches and circuit breakers. Its functions are to insulate, suppress corona and arcing, and to serve as a coolant.
The expected life of transformer oil is 40 years or more. In order to meet this expectation, TRANSFORMER OIL has good chemical stability when exposed to elevated temperatures, which is essential to prevent the formation of acidic materials that impair the insulating properties of the oil.
