RAIDO Transformer Oil du2

Description:

RAIDO Transformer Oil du2 this transformer oil is a good refined mineral oil with a very big specific resistance. Moreover this is a thin oil, so that the eventually developed heat can quickly be removed by a good circulation. By addition of special additives this oil obtained the following properties:

  • a very good high specific resistance
  • a very good removal of heat
  • a low vapour tension and "tangent delta" value
  • a high breakdown voltage

Application:

RAIDO Transformer Oil du2 this high quality transformer oil is suitable for application in transformers and oil-filled electrical switches and initial resistors.

!!!Remark: Due to the high grade of refining this oil is also suitable as lubricant in cooling installations, working with a coolant based on sulphurdioxide.
