Transformer oil is a highly refined insulating and cooling oil used in transformers, circuit breakers, and other electrical power equipment to ensure safe and efficient operation. Its primary functions are to provide electrical insulation between internal components, dissipate heat generated during operation, and protect equipment from moisture, oxidation, and contamination. By maintaining proper cooling and insulation, transformer oil helps prevent electrical faults, reduces the risk of overheating, and extends the lifespan of critical power infrastructure. As a result, it plays a vital role in maintaining the reliability, performance, and safety of electrical distribution and transmission systems.
