Description:

Shell Diala S2 ZU-I Dried 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. It has excellent low temperature properties and is dried to achieve a higher breakdown voltage than required by standard industry norms.

Shell Diala S2 ZU-I Dried gasoil tariff meets both the established and the new industry copper corrosion tests.

Performance, Features and Benefits:

•Extended oil life 

Shell Diala S2 ZU-I Dried gasoil tariff offers inherent natural resistance to oil degradation through oxidation. 

•System efficiency 

The good low temperature properties of the oil ensure proper heat transfer inside the transformer, even from lowest starting temperatures. Shell Diala S2 ZU-I Dried gasoil tariff is specially dried and handled to achieve a low water content and retain a high breakdown voltage at point of delivery. This enables it to be used in many applications without further treatment. 

•Transformer protection 

Shell Diala S2 ZU-I Dried gasoil tariff is non-corrosive towards copper, with no need for passivation. Shell Diala S2 ZU-I Dried 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: ft IEC 62535 and ASTM D1275B. 

Application:

•Transformers 

Electrical insulating oil for grid and industrial transformers. 

•Electrical equipment 

Components such as rectifiers, circuit breakers and switchgears.
