Shell Diala S2 ZX-A Inhibited Electrical Insulating Oil is formulated from refined mineral oils. Its effective dielectric properties, oxidation stability and efficient transfer of heat at all temperatures make it the perfect oil for protecting transformers and electrical equipment such as circuit breakers and rectifiers. It also provides efficient transformer operation at low temperatures and extended oil life for cost savings. It's available in a 55-gallon drum and in bulk quantities. Shell Diala S2 ZX-A is an inhibited 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 ZX-A meets both the established and the new industry copper corrosion tests.

Extended oil life: Shell Diala S2 ZX-A is an inhibited oil giving outstanding oxidation performance and an extended oil life. System efficiency: The good low temperature properties of the oil ensures proper heat transfer inside the transformer, even from low starting temperatures. Transformer protection:åÊShell Diala S2 ZX-A is non-corrosive towards copper, with no need for additional passivation. Shell Diala S2 ZX-A meets all relevant tests on copper corrosion ASTM D1275, and also the latest more severe tests: IEC 62535 and ASTM D1275B.


  • Transformers Electrical insulating oil for grid and industrial transformers.
  • Electrical equipment Components such as rectifiers, circuit breakers and switchgears.

Specification and Approvals
Shell Diala S2 ZX-A meets the requirements of ANSI/ASTM D 3487
Type II Storage precautions
The critical electrical properties of Shell Diala S2 ZX-A are easily compromised by trace contamination with foreign material. Typically encountered contaminants include moisture, particles, fibres and surfactants. Therefore, it is imperative that electrical insulating oils be kept clean and dry. It is strongly recommended that storage containers be dedicated for electrical service and include airtight seals. It is further recommended that electrical insulating oils be stored indoors in climate-controlled environments.

Causes skin irritation. Causes eye irritation. Wash after handling. Wear protective gloves/ protective clothing/ eye protection. IF ON SKIN, wash with plenty of soap and water. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. If skin irritation occurs: Get medical advice/attention. If eye irritation persists: Get medical advice/attention. Take off contaminated clothing and wash before reuse. Dispose of contents/ container to an approved waste disposal plant.
