Shell Diala
Shell's Diala range has been upgraded with the introduction of Shell Diala S4 ZX-I.
A new GTL-based product engineered for SHELL’S optimum performance in the latest generation of transformers.
Like before Shell Diala S4 ZX-I offers enhanced protection, longer oil life and greater efficiency. It meets the specific demands imposed by the reduced size, increased loads, higher voltages and longer operational lifetimes of today’s transformers.
Enhanced protection Shell Dial S4 ZX-I
Oil is at the heart of your transformer. The Shell Diala range presents a number of options for the best possible protection The new Shell Diala S4 ZX-I exceeds IEC 60296:Ed 4 2012 highest oxidation stability, low sulphur specification. In fact it has essentially zero sulphur (below detection limits) which means that the risk of oil related copper corrosion is removed.
Longer oil life: Shell Diala S4 ZX-I transformer oils are designed to last
supporting the extension of your transformer lifetime. Shell Diala S4 ZX-I exceeds the 500-hour oxidation test limit and extends oil life through its exceptional resistance to the effects of ageing, sludge formation and deposit build-up.
Greater efficiency with Shell Diala S4 ZX-I
For optimum transformer performance, electrical insulating oil must maintain its characteristics over a wide range of operating temperatures. Theorectical modelling predicts that Shell Diala S4 ZX-I could deliver improved operational performance under overload conditions due to enhanced thermal properties.
