Transformer Oil

“Ever Brilliant General Trading LLC.” Serves its client by providing transformer oil as a refinement product of heavy Oil which is stable at high temperatures and has excellent electrical insulating properties used in oil-filled wet transformers, some types of high-voltage capacitors, fluorescent lamp ballasts, and some types of high-voltage switches and circuit breakers. There are 2 types of transformer oils, Type 1 and type 2. Type 1 is an uninhibited oil and Type 2 has an oxidation inhibitor added to it. Oxygen is an aging accelerator when it gets inside the transformer. The provided transformer oils adhere to IEC and ASTMA standards.
