Description:

Shell Diala S3 ZX-IG Dried is a premium inhibited insulating oil manufactured from highly refined mineral oils. It offers very high oxidation stability, good dielectric strength, gas absorbing behaviour and excellent low temperature properties.

Shell Diala S3 ZX-IG Dried meets both the established and new industry copper corrosion tests.

Performance, Features and Benefits:

•Extended oil life 

Shell Diala S3 ZX-IG Dried is a fully inhibited oil giving outstanding oxidation performance and an extended oil life. 

Diala S3 ZX-IG Dried provides gas absorbing performance in transformers running under very high voltage and electrical stress. This makes it particularly suitable for Generator transformer and HVDC converter applications.
 
•Transformer protection 

Shell Diala S3 ZX-IG Dried is non-corrosive towards copper, with no need for additional passivation. 

Shell Diala S3 ZX-IG Dried meets all relevant tests for copper corrosion, namely the established DIN 51353 (Silver Strip Test), ASTM D1275, and also the latest more severe tests: IEC 62535 and ASTM D1275B. 

•System efficiency 

The good low temperature properties of the oil ensures proper heat transfer inside the transformer, even from very low starting temperatures. 

Shell Diala S3 ZX-IG Dried 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. 

Application:

•Transformers 

All Power transformer types and applications (e.g. generator transformers, shunt reactors, distribution transformers) and high voltage DC (HVDC) converter stations. 

•Electrical equipment 

Components such as rectifiers, circuit breakers, bushings, instrument transformers and switchgears.
