TRANSFORMER OIL
INHIBITED ELECTRICAL INSULATING OIL
Phillips 66® Transformer Oil is a highly refined electrical insulating oil developed for use in oil-immersed transformers, capacitors, tap changers, and circuit breakers where the equipment manufacturer specifies a Type II inhibited oil meeting ANSI/ASTM D3487-09 requirements.

Features & Benefits
- Excellent insulating properties
- High dielectric strength(1)
- Low power factor
- Resists oxidation and deposit formation
- Excellent low-temperature properties
- Compatible with materials used in transformers
- Does not contain any PCBs (1)Note: In order to maintain its high dielectric strength for use as an insulating oil, the oil must be kept clean and dry. Contamination with even a small amount of water will significantly decrease the dielectric strength. The drums are sealed at the terminal with a blanket of dry air to keep moisture out. The drums should be stored indoors and covered to protect them from dust and debris. If stored outdoors, they should be positioned on their sides or upside down and covered to protect them from exposure to the elements. Every effort should be made to use the entire drum once the seal is broken to help prevent contamination. If contamination is suspected, always inspect the drum and test the oil for dielectric strength before use.
Applications
- Oil-immersed transformers
- Circuit breakers & switches
- Fuses
- Tap changers
- Other oil-immersed electrical equipment
