The Diala product benefits
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 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.
