THE SHELL DIALA RANGE FOR SPECIAL APPLICATIONS

A long and predictable oil life is critical to transformer performance. The Shell Diala range of oils includes inhibited and uninhibited electrical insulating oils to give you a choice of performance profiles to best match your requirements. Shell’s latest products meet the IEC 60296 high level of oxidation performance and exceed the 500-hour oxidation test limit.

system efficiency To help your transformer perform to its design standards, an electrical insulating oil must maintain its characteristics over a wide range of operating temperatures. All the Shell Diala electrical oils are designed to offer excellent heat transfer and dielectric properties, even at the lowest start-up operating temperatures. In addition, Shell Diala oils are formulated to offer excellent resistance to the effects of ageing, sludge formation and deposit build-up.

CORROSIVENESS TO COPPER

SPECIALIST APPLICATIONS

All Shell Diala products meet the industry standards for copper corrosion: IEC 62535, ASTM D1275B and DIN 51353.

Shell offers several products designed for specialist applications. These include n Shell Naturelle Transformer Oil S4 I. This is a syntheticester-based product that offers excellent low-flammability characteristics. It has a flashpoint of 275°C, is fully biodegradable and meets European Union Ecolabel requirements n Shell Diala Switchgear Oil, which is designed for switchgear applications and is highly suitable for applications likely to operate at very low temperatures without additional heating.

In addition, Shell is committed to minimising insulating-oilrelated copper corrosion in transformers. The organisation works with equipment manufacturers, utility companies and specifying technical committees to understand the causes of corrosion and to reduce or even eliminate sulphur levels in its electrical insulating oils.
