Hyvolt II Electrical Insulating Oil Marketing Specification
HyVolt II Transformer Liquid
Electrical Insulating Oil (Transfromer Fluid, Transformer Liquid, Transformer Oil) Marketing Specification
This electrical insulating oil, also known as transformer fluid, transformer oil or transformer liquid, is produced from a severely hydrotreated naphthenic oil to meet the specification requirements defined in ASTM D3487. HyVolt products have very low pour points and excellent oxidation stability.
