Product Description
VOLTESSO™ brand insulating oils are formulated from high quality basestocks and select additives that provide excellent low temperature performance and resistance to oxidation and sludge formation in electrical service. These high quality electrical insulating oils are designed and manufactured to provide cooling and to help insulate transformer components against electrical corona and arching.
VOLTESSO 35 is recommended for use in power transformers, especially those subject to cold start-up, or have forced oil cooling, including associated load tap changers, switches and circuit breakers that operate at ambient temperatures below -25°C. Voltesso meets Canadian Standards Association C50-08 specifications for Class A, Type I oils.
Features and Benefits
Features |
Advantages and Potential Benefits |
Excellent low temperature fluidity |
Improves circulation and heat transfer and allows operation at low temperatures in remote locations |
