Abstract
The electrical insulating fluid, which has a high fire point, a relatively low viscosity and is less costly than conventional saturated hydrocarbon oils, includes about 20 to about 90 weight % of a saturated aliphatic or aromatic hydrocarbon oil having an average molecular weight greater than 400 and a fire point great than 300°C, about 10 to about 80 weight % of an ester oil of pentaerythritol having a fire point greater than 300°C and 0 to about 2 weight % of an antioxidant.
