Voltro™ Transformer Insulating Oil

Our selection of industrial oils includes products engineered for use in applications where contact with electrical equipment and transformers is necessary. Transformers, circuit breakers, and other electrical insulating and cooling applications require transformer oils to prevent overheating and premature repairs. Renkert Oil designed Voltro for these applications by our industrial oil experts.

Renkert’s Voltro™ Transformer Oil is highly refined mineral oil, derived from paraffinic crude. Voltro, which is severely hydrotreated and created specifically for electrical insulating and cooling applications, complies with ASTM D3487 and Doble Tops. This insulating mineral oil is stable at the increased temperatures associated with electrical insulation applications.

Voltro™ Transformer Insulating Oil is ideal for electrical insulation and transformer applications due to its stability, low moisture, high flashpoint, exceptional oxidation stability, and its other properties. The oil industry experts at Renkert Oil have the technical experience and knowledge to provide informed recommendations for oil based on your needs.
