TRANSFORMER OIL Chemical compatibility with O-rings, rubbers, & plastics

Transformer oil is a specialized oil used in transformers and other electrical equipment to insulate, cool, and protect the components from moisture and oxidation. It is formulated to have high dielectric strength, thermal stability, and resistance to oxidation and degradation, ensuring the efficient and reliable operation of electrical systems. Transformer oil is employed in various industrial and electrical applications, providing insulation and cooling for power transformers, circuit breakers, and capacitors. Proper handling and storage of transformer oil are essential to maintain its quality and performance. Safety measures, including the use of appropriate protective equipment and adherence to handling protocols, are crucial when working with transformer oil, as it can pose environmental and health risks if spilled or mishandled. Its effectiveness in insulating and cooling electrical components makes transformer oil a valuable fluid in ensuring the reliability and longevity of electrical systems.
