A fully synthetic, nonvolatile and noncorrosive silicone fluid. The high fire point and the virtually self extinguishing behaviour represent a much lower fire hazard than conventional transformer fluids. An outstanding thermal stability, even under the presence of air, allows a higher thermal utilization in comparison with other liquid coolants.


  • fully synthetic fluid
  • maximum purity
  • non corrosive
  • lowest environmental impact
  • long-term-stable dielectric properties
  • good compatibility with other insulating materials used in transformers



POWERSIL® FLUID TR 50 fulfills the requirements of class K3 according to IEC 61100 and is classified as L-NTUK-8360300 according to IEC 61039.

Spezifische Merkmale von POWERSIL® FLUID TR 50

  • Hoher Brennpunkt
  • Hoher Flammpunkt

When used as coolant and insulation fluid, POWERSIL® FLUID TR 50 is dried and degassed in the same way as conventional transformer fluids. The compatibility of silicone fluids to other materials normally used in transformers has been demonstrated in a number of published articles.



POWERSIL® FLUID TR 50 should be stored in the tightly sealed original container. The liquid should be able to adapt their temperature to that of the environment before use. At high humidity this is especially recommended.


Beeing a silicone fluid, the product has a virtually unlimited self life.


The 'Best use before end' date of each batch is shown on the product label.


Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
