Electra SG-1 Transformer Oil is another highly refined electrical insulating oil developed for use in oil-immersed transformers, capacitors, tap changers, and circuit breakers where the equipment manufacturer specifies a Type II inhibited oil meeting ANSI/ASTM D3487-09 requirements. It plays crucial role in various electrical applications. Its primary function is to insulate and cool the windings and core of power transformers and other electrical transformers. It acts as both an insulator and a coolant, ensuring the safe transfer of electrical power while preventing overheating. Electra SG-1 is also employed as an insulating medium in oil-filled circuit breakers and switchgear systems, providing the necessary dielectric strength to protect against short circuits and electrical faults.
