Manufacturer's description
Premium Inhibited Electrical Insulating Oil. Shell Diala S4 ZX-I (EU) is the High-Grade electrical insulating oil from Shell designed to meet the challenges presented by the latest power transformers. It offers an extended oil life and passes nowadays sulphur corrosion tests. Shell Diala S4 ZX-I (EU) is manufactured from carefully selected, premium (iso) paraffinic mineral base oils. These base oils offer a high degree of compositional consistency and have an excellent response to antioxidant. In addition, they are globally available and free from PCBs, DBDS and passivators.
Performance & benefits
- Extended oil lifeShell Diala S4 ZX-I (EU) is a fully inhibited oil giving outstanding oxidation performance and an extended oil life. Shell Diala S4 ZX-I (EU) is also suitable for use in highly loaded applications.
- Transformer protectionShell Diala S4 ZX-I (EU) is manufactured from carefully selected, premium, virtually sulfur fee, mineral base oils, making it intrinsically non-corrosive towards copper, without the need for passivation or other additives. Shell Diala S4 ZX-I (EU) meets all relevant tests for copper corrosion, namely the established DIN 51353 (Silver Strip Test), and the latest more severe tests: IEC 62535 and ASTM D1275.
- System efficiencyThe good low temperature viscometric properties of the oil ensure proper heat transfer inside the transformer, even from very low starting temperatures.
- IEC 60296 (Edition 5 year 2020); Type A, fully inhibited high grade oils
