The Shell Diala range of electrical oils has been developed to enable equipment manufacturers and power companies to select an oil that can deliver optimum value to operations through enhanced equipment protection, long oil life, and high system efficiency.

EQUIPMENT PROTECTION

An electrical insulating oil lies at the heart of your transformer. The Shell Diala range of electrical insulating oils offers a number of options, including the latest fully inhibited, ultra-low-sulphur technology that meets all the current IEC and ASTM standards for copper corrosion, and is designed to ensure the best possible protection for your high-value assets. Shell also offers special gas-absorbing insulating oils for use in high-electrical-stress applications such as those found in high-voltage, direct-current (HVDC) transformers.

OIL LIFE

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 across a wide range of operating temperatures. All 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.
