Transformer Oil (Insulating Oil)
Application areas:
A highly refined mineral insulating oil designed for use in electrical power equipment requiring excellent dielectric strength and heat transfer.
Suitable For:
-Oil filled distribution transformers
-Power transformers
-Potential and current transformers
-High-voltage switchgear
-Circuit breakers (non arc quenching type)
-Oil immersed electrical equipment
-Capacitors requiring mineral insulating fluid
Functions:
-Provides electrical insulation
-Transfers heat from windings to tank walls
-Protects internal components from moisture
Perfomance benefits:
-Excellent dielectric strength ensures reliable insulation
-Outstanding oxidation stability extends the fluid’s working life
-Superior heat transfer capability keeps transformer temperatures in control
-Low sludge formation keeps coils and windings clean
-Very low moisture content maintains insulation integrity
-Compatible with transformer materials (paper, copper, metals)
-Helps prevent equipment failures and improves service life
Special Features:
-Uninhibited formulation using highly refined Group II base oils
-Low sulfur content and excellent chemical stability
-Efficient cooling properties for heavily loaded transformers
-High resistance to electrical stress
-Low pour point for cold start performance
