                         Product              Sinopec Transformer Oil 
     
                         Summary              Product description 
     
                                              Sinopec Transformer Oil is a series of products blended using 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. There are four grades, 10, 25, 40 and 45, which are selected on 
                                              the basis of their low-temperature performance. None of the grades contain 
                                              harmful polychlorinated biphenyls (PCBs). 
     
         Applications 
         Sinopec Transformer Oil is suitable for use in: 
     
              •    Oil-filled transformers, operating at 330 kV or less, where it acts as a non-conducting insulating and cooling medium. 
              •    Oil-immersed switch-gear. 
              •    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.
