Naphthenic Transformer Oil

​

Goncord ester based series for transformer oi is synthesized from an array of saturated fatty acids and pentaerythritol under carefully controlled conditions.   It has excellent lubricity, low expansion coefficient, excellent insulation properties and high breakdown voltage. It also has outstanding flame retardancy and ultra-high thermal oxidation stability, as well as ultra-low water content.
