Every part of your machine or process has been meticulously engineered, so you need a lubricant that will protect and maintain its efficiency. The Shell Diala range of electrical oils lets you select the oil designed to deliver optimum value to your operation through enhanced equipment protection, long oil life and high system efficiency.
Our new electrical oil – Shell Diala S4 ZX-I is based on GTL technology - derived from natural gas rather than from crude oil. Pure, predictable and with no sulphur 1 and very low aromatic and unsaturates contents, Shell’s GTL base fluids have higher flash points, lower densities and TYPICALLY more EFFECTIVE thermal properties than conventional mineral oils.
1 Below the detection limits according to ISO 14596/ASTM D2622
Shell's range of electrical oils
The Shell Diala range includes inhibited and uninhibited electrical insulating oils, as well as the latest fully inhibited, ultra-low-sulphur technology, to give you a choice of performance profiles to suit your needs. Shell’s latest products meet the IEC 60296 high level of oxidation performance and exceed the 500-hour oxidation test limit.
Shell Diala case study
By upgrading to Shell Diala S3 ZX-I, transformer specialist Elotec was able to reduce their oil drying time and order larger volumes of a single lube. These changes led to reported annual savings of US$11,382.
