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.

      Great option for a professional looking backdrop
      Color: Black, Size: B-102''-3 Panel
      I decided to try these wall dividers for my home office space since it does not have a door. I wanted to have my video calls without the rest of the room in the feed to give it a more professional feel. These being on castors make them super easy to move into position and roll off to the side when not in use. They are stable, much more than the folding screens I have tried in the past. That they are connected by the middle piece and not the top/bottom of each other allows you to adjust the positioning to your needs. Overall, this did exactly what I needed and was an affordable option. I also like that they are highly portable: if you want to take them for a booth or event, the poles all disassemble into manageable lengths that easily fit in a car and take very little time to set up again. The only thing I would change is to include a bag to store them in for transportation.

      if you are going to be moving them a lot, buy something more sturdy.
      Color: Black, Size: Wheel-6 Panel
      I use these at our churchc. They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places. But they wqould work especially well if you were not constantly moving them as we do. They are a bit of a pain to assemble.
