Transformer Oils

Royal Transformer Oils are highly - refined mineral oil that are stable at high temperatures having excellent electrical insulating properties.

It is used in oil-filled transformers, some types of high voltage capacitors, fluorescent lamp ballasts, electricity & power generations and some types of high voltage switches & circuit breakers.

Its functions are to insulate, suppress corona & arceing, and to serve as a coolant.
