Shell DIALA S4 ZX-I is an inhibited insulating oil (cooling oil) and the perfect companion when it comes to cooling and thus protecting your transformers and electrical equipment. Thanks to the cooling oil, you can ensure efficient operation of your equipment throughout its life.
Made from sulfur-free base oil, the cooling oil offers excellent low-temperature properties and extremely high oxidation resistance. It also offers - due to the drying of the oil - a significantly better breakdown voltage than is often required. In addition, the cooling oil can be used directly in many cases without further drying.
Another advantage of the cooling oil is that it is inherently non-corrosive to copper.
Of course, it meets the IEC 60296 standard as well as the copper corrosion tests DIN 51353 (silver stripe test), ASTM D1275 and D1275B and IEC 62535.
