Manufacturer's description

Premium Inhibited Gas Absorbing Electrical Insulating Oil. Shell Diala S4 ZX-IG is a gas absorbing electrical insulating oil from Shell which meets the performance of both IEC 60296 higher oxidation stability and low sulphur as well as ASTM D3487 Type II. In addition it has been designed to meet the gas absorbing challenges presented by specialised equipment such as high voltage instrument transformers and bushings. It offers an extended oil life with the peace of mind of zero sulphur content. Shell Diala S4 ZX-IG is manufactured from zero sulphur base oils produced using Shell’s GTL (gas-to-liquid) technology. These base oils offer a high degree of compositional consistency and have an excellent response to anti-oxidant. The product is free from PCBs, DBDS and passivators, containing only DBPC antioxidant, and a low level of aromatic hydrocarbon (for gas absorption behaviour). Shell Diala S4 ZX-IG meets both the established and new industry copper corrosion tests.

Performance & benefits

• Extended oil lifeShell Diala S4 ZX-IG is a fully inhibited gas absorbing oil giving outstanding oxidation performance and an extended oil life. It has the ability to absorb gases such as hydrogen which can develop under partial discharge conditions. This makes Shell Diala S4 ZX-IG the recommended Shell product for special applications with high voltage gradients, such as bushings and instrument transformers requiring gas absorbing properties.
• Transformer protectionShell Diala S4 ZX-IG is manufactured from a zero sulphur* base oil, making it intrinsically non-corrosive towards copper, without the need for passivation or other additives (apart from the DBPC antioxidant, and a low level of aromatic hydrocarbon (for gas absorption behaviour)). Shell Diala S4 ZX-IG meets all relevant tests for copper corrosion, namely the established DIN 51353 (Silver Strip Test), ASTM D1275, and also the latest more severe tests: IEC 62535 and ASTM D1275B. *Sulphur content below 1ppm detection limit of ASTM D5185
• System EfficiencyThe good low temperature viscometric properties of the oil ensure proper heat transfer inside the transformer, even from very low starting temperatures. Shell Diala S4 ZX-IG is specially dried and handled to achieve a low water content and retain a high breakdown voltage at point of delivery. This enables it to be used in many applications without further treatment.
• IEC 60296 (2020): Table 2 Transformer Oil (I) (Inhibited Oil) Section 7.1 ("Higher oxidation stability and low sulphur content")
