Shell Diala S2 Zu-I is an UNINHIBITED ELECTRICAL INSULATING OIL
Shell Diala S2 ZU-I 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 even at low temperatures. Shell Diala S2 ZU-I meets both the established and the new industry copper corrosion tests.
Components such as rectifiers, circuit breakers and switchgears.
The critical electrical properties of Shell Diala S2 ZU-I 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.
