Product Information

Transformer oil is a specialized electrical insulating oil made from deeply refined mineral base oil. Its three core functions are insulation, cooling and heat dissipation, and arc suppression and extinction.

Used in oil-immersed power transformers, distribution transformers, instrument transformers, reactors and high-voltage oil switches. It effectively insulates high-voltage components, circulates to remove heat generated during operation and suppresses arcing to support stable, safe operation of high-voltage electrical equipment.

Main grades: No. 25 and No. 45. It complies with IEC international standards. A complete set of export documents, including MSDS, TDS and COA, can be provided. FOB exports and OEM private labeling are supported.
