Transformers produce a lot of heat when in operation. As heat-transfer media, coolants are indispensable for dissipating this energy. For many years now, WACKER has offered silicone-based insulating fluids with exceptional oxidation resistance and thermal stability for this purpose.
The latest product from the WACKER laboratories is POWERSIL® Fluid TR20. The insulating fluid has a very low viscosity of 20 mm2 per second. With a flashpoint of 240 °C and ignition point of 270 °C, it has properties that guarantee its reliability when used in electrical machinery, including power generators.
In addition, the fluid has an extraordinary cold start capability. Its pour point is below -50°C which is a decisive advantage when applied to wind turbines. And since POWERSIL® Fluid TR20 has such low viscosity even at low temperatures, the transformer will always be in working order.
Furthermore, the new silicone fluid is extremely resistant to oxidation, giving electrical machinery a significantly longer service life. POWERSIL® Fluid TR20 also lends itself to all other applications that must cope with a high energy density and where huge amounts of heat must be dissipated rapidly. The insulating fluid is also ideally suited to face the challenges of electrical mobility.
