Description

Sinopec Super Insulated 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. There are three kinds of transformer oil, I-10℃ super insulated transformer oil, I-20℃ super insulated transformer oil and I-40℃ super insulated transformer oil, which meet the requirements of IEC60296:2012. Sinopec transformer oil IEC don’t contain polychlorinated biphenyls (PCBs).

Features & 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.

Sinopec Super Insulated transformer oil meets the requirements of IEC60296: 2012.

  •  For the special application requirements (high oxidative stability and low sulfur content) of transformer oil the oil comply with IEC 60296:2012, including clause 7.1 requirements.

Applications

Sinopec Super Insulated Transformer Oil is suitable for use in:

  • Oil-filled transformers, where it acts as a non-conducting insulating and cooling medium.

  • Oil-immersed switch-gear.

  • Other electrical insulating applications.

      Sturdy good grip
      Bought this because it had good reviews and looked sturdy... with the previous, other name tumblers, if you dropped the lids they broke and the company dont have replacement lids so you had to buy the whole thing! Gets expensive... no issues with this tumbler.. my husband really likes it, fits our cup holders and has a good grip..

      Doesn’t maintain hot too long.
      I love this cup because the material is good for heavy duty jobs like mine. I took off one star because it does keep hot but not for super long, it lasts hot for about 2-3 hours. Other than that it’s easy to wash and the magnet that comes on the cup is super strong which comes in handy for not loosing it. It magnetized on to the cup.
