What is transformer oil?

Transformer or insulating oils are very pure highly refined oils optimized to meet the stringent requirements of the international Standards. They are a special type of oil with significant electrical insulating properties. SPEL TRANSOL Transformer oils are designed to help keep the windings intact at elevated temperatures and work by preventing the formation of arcing or corona discharges between the winding, transformer core, and surrounding environment. Transformer oils also have excellent anti-oxidative properties.
