ABSTRACT:
Dielectric fluids comprising oil fractions derived from highly paraffinic wax are provided. Further provided are processes for making these dielectric fluids comprising oil fractions derived from highly paraffinic wax. The dielectric fluids are useful as insulating and cooling mediums in new and existing power and distribution electrical apparatus, such as transformers, regulators, circuit breakers, switchgear, underground electrical cables, and attendant equipment.
