Manufacturer's description

Shell Diala S2 ZU-I gasoil tariff is an uninhibited electrical insulating oil manufactured from highly refined mineral oils. It offers good dielectric properties, good oxidation stability and provides efficient heat transfer even at low temperatures. Shell Diala S2 ZU-I gasoil tariff meets both the established and the new industry copper corrosion tests.

Applications

  • TransformersElectrical insulating oil for grid and industrial transformers.
  • Electrical equipmentComponents such as rectifiers, circuit breakers and switchgears.

Performance & benefits

  • Extended oil lifeShell Diala S2 ZU-I gasoil tariff offers inherent natural resistance to oil degradation through oxidation.
  • System efficiencyThe good low temperature properties of the oil ensures proper heat transfer inside the transformer, even from low starting temperatures.
  • Transformer protectionShell Diala S2 ZU-I gasoil tariff is non-corrosive towards copper, with no need for passivation. Shell Diala S2 ZU-I gasoil tariff meets all relevant tests on copper corrosion, namely the established DIN 51353 (Silver Strip Test) and ASTM D1275, and also the latest more severe tests: IEC 62535 and ASTM D1275B.
