Transformer oil is used to insulate high-voltage electrical infrastructure such as transformers, capacitors, switches and circuit breakers. Transformer oils are designed to operate effectively at very high temperatures, cooling, insulating, and stopping corona discharges and arcing.
Repeated exposure may cause skin dryness or cracking. Eye contact May cause temporary eye irritation. Acute and chronic health hazards Prolonged or repeated contact with used oil may cause serious skin diseases, such as dermatitis and skin cancer.
Depending on the Power rating and specification, Power transformers can further be classified into three categories: Small power transformer, Medium Power transformers, and the Large power transformers.
