Product Description
SINOPEC Super Transformer Oil is blended with highly refined mineral oil and a selected antioxidant. It is designed for insulating and cooling transformers, oil-immersed switch-gear and other electrical insulating applications. SINOPEC Super Transformer Oil doesn't contain polychlorinated biphenyls (PCBs).
These data are given as an indication of typical values and not as exact specifications.
Applications
SINOPEC Super Transformer Oil is suitable for use in:- Oil-filled transformers, where it acts as a non-conducting insulating and cooling medium.
- Other electrical insulating applications.
Features and benefits
- Excellent dielectric (insulating) properties, effectively prevent discharge in an electric field.
- Low viscosity and low density lead to the oils having good cooling properties and good heat transfer characteristics at room temperature and below, and so ensure effective cooling of transformer core and coils.
- Even at very low temperatures the oil viscosity remains low, and therefore allows the transformer to be started up under very cold conditions without problem.
- Excellent oxidation stability characteristics are provided by the stable base oil together with the high-performance oxidation inhibitor system, and prevent the formation of acidic material and sludge in service, extending the life of the oil.
- All four grades meet the requirements of IEC 60296:2003 for transformer oils.
