Shell Diala S2 ZX-An Reliable performancen Meets ASTM D3487 Type II

Every part of your machine or process has been meticulously engineered, so you want to use a lubricant that has been designed to ensure that your equipment is well protected and works efficiently.

The Shell Diala range of electrical oils has been developed to enable equipment operators to select the oil that will deliver optimum value to their operations throughn system protectionn long oil lifen system efficiency.

a leaDing inhiBiteD electRical insUlating oilShell Diala S2 ZX-A is a fluid designed to protect your valuable equipment. Widely recognised and approved by leading manufacturers, it is non-corrosive to copper and does not require a copper passivator, as proved in the latest and most severe copper corrosion tests.

Manufactured from highly refined mineral oils, it resists oil degradation by oxidation and has good low-temperature properties, which are vital for efficient heat transfer inside the transformer, even at low temperatures.
