Naphthenic transformer oil
Product code: W003
Exol Transformer Oil is manufactured using special naphthenic mineral base oils which possess inherently high
dielectric strength. It is manufactured under strict conditions to conform to IEC 60296 Edition 4.0 and BS 148 Class I
& II requirements.
Excellent oxidation stability Excellent low temperature performance
Excellent cooling properties High dielectric strength for electrical insulation
Transformer Oil is recommended for oil filled power and distribution transformers, rectifiers, circuit breakers and
switchgears where an uninhibited transformed oil or dielectric fluid is specified. It will dissipate heat, insulate
windings and quench the spark between the opening contacts when tap changing.
Care should be taken to avoid even the smallest contact with water. Once opened, the product is prone to
contamination with moisture from the air.
Transformer Oil meets the requirements of the following standards:
IEC 60296 Edition 4.0 IEC 62535
DIN 51353 ASTM D1275 Method B
BS 148 Class I & II AS 1767-1975
ASTM D3487 Type I
