XCELTHERM® ELECTRICAL INSULATING OIL, TYPE II

XCELTHERM® Electrical Insulating Oil (Type II) meets military standard specifications for electrical oil applications. XCELTHERM® EIO-II has and is high electrical resistance both thermally and oxidatively stable. XCELTHERM® EIO-II is intended for use in most common electrical insulating oil applications where normal oxidation resistance is required. It is compatible with other electrical insulating oils, including Shell Diala® A.
