Empower TRANSFORMER OIL is designed for human safety and free from carcinogenic Poly chlorinated Bi-phenyls (PCB) and Poly aromatic hydrocarbon (PAH).

PROPOSED USAGE

• Electric transformers
• Switch gears
• Circuit breakers which require insulating fluids
• Has very high oxidation stability
• Excellent ageing properties resulting in long product life

Our product conforms to IEC 60296:2003/BS-148:1998

Note:

• 1. The above data is indicative of recent average values only. Minor variations which do not affect product performance or quality may be expected in manufacture.
• 2. Specific requirements can be custom-made on request.
