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
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.
