Complete documentation
Manufacturer's description
Uninhibited electrical insulating oil. Shell Diala S2 ZU-I Dried gasoil tariff is an uninhibited electrical insulating oil formulated from highly refined mineral oils. It offers good dielectric properties and good oxidation stability and provides efficient heat transfer. It has excellent low-temperature properties and is dried to achieve a breakdown voltage higher than that required by the industry standards. Shell Diala S2 ZU-I Dried gasoil tariff passes both the established and the new industry copper corrosion tests.
Applications
- Transformers: Electrical insulating oil for grid and industrial transformers. · Electrical equipment: Electrical equipment such as electrical valves, circuit breakers and switches. ·
Performance & benefits
- Extended oil life: Shell Diala S2 ZU-I Dried gasoil tariff offers a natural resistance to degradation by oxidation. · System efficiency: The oil's good low-temperature properties ensure adequate heat transfer inside the transformer, starting from even the lowest temperatures. Shell Diala S2 ZU-I Dried gasoil tariff is specially dried and handled to achieve a low water content and maintain a high breakdown voltage at the point of delivery. This allows 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, without the need for passivation. Shell Diala S2 ZU-I Dried gasoil tariff passes all the relevant copper corrosion tests, namely DIN 51353 (Silver Strip Test) and ASTM D1275, and also the latest severe tests: IEC 62535 and ASTM D1275B. ·
