What applications use Chevron transformer oil?

Chevron transformer oils are used as insulating and cooling fluids in distribution transformers, power transformers, and certain switchgear that require mineral insulating oil meeting utility specifications. They are commonly applied in utility grids, industrial substations, renewable interconnection transformers, and OEM fill for new equipment where the procurement specification references standard mineral oil performance requirements. Selection depends on the exact Chevron product grade and whether inhibited or uninhibited oil is required by the asset design and maintenance strategy.
