Oil in a traction transformer serves two primary purposes: insulation and cooling. It acts as an insulating medium, preventing electrical discharges between internal components by filling gaps and covering surfaces. The oil also absorbs heat generated during operation and transfers it to the transformer’s external cooling surfaces or radiators, effectively dissipating thermal energy. This prevents overheating, maintains optimal operating temperatures, and prolongs the transformer’s lifespan. High-quality oil ensures the transformer’s electrical and thermal performance, contributing to safety and reliability.
