Formerly Shell Diala AX Transformer Oil - 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.

Applications

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

Advice on applications not covered in this leaflet may be obtained from your Shell Representative.

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 andinclude airtight seals. It is further recommended that electrical insulating oils be stored indoors in climate-controlled environments.

Health and Safety
Guidance on Health and Safety is available on the appropriate Material Safety Data Sheet which can be obtained from your Shell representative.
Shell Diala S2 ZX-A is free from polychlorinated biphenyls (PCB).
Protect the environment
Take used oil to an authorized collection point.
Do not discharge into drains, soil or water.

Frequently asked questions

Find answers to common questions about our products and services

  • Yes. Shell Diala S2 ZX-A is the current name for the product formerly marketed as Shell Diala AX Transformer Oil. It is the same inhibited electrical insulating oil formulated from highly refined mineral oils.

  • This oil is designed for grid and industrial transformers as well as other electrical equipment including rectifiers, circuit breakers, and switchgears. For applications not covered by these categories, consult your Shell representative.

  • An inhibited oil contains antioxidant additives that resist oxidation during use. For Shell Diala S2 ZX-A, this results in outstanding oxidation performance and an extended service life, which can reduce the frequency of oil changes and lower long-term operating costs.

  • Shell Diala S2 ZX-A has good low-temperature properties that ensure efficient heat transfer inside the transformer even from low starting temperatures, supporting reliable system operation in cold conditions.

  • Yes. Shell Diala S2 ZX-A is non-corrosive towards copper and requires no additional passivation treatment. It meets the copper corrosion tests ASTM D1275 and ASTM D1275B, as well as the more demanding IEC 62535 test.

  • Because trace amounts of moisture, particles, fibres, or surfactants can compromise the oil's critical electrical properties, it should be kept clean and dry at all times. Storage containers should be dedicated to electrical service use, fitted with airtight seals, and kept indoors in a climate-controlled environment.
