    Shell Diala S2 ZX-A Applications:

    Shell Diala S2 ZX-A Oils are primarily intended for use in:

    Circuit breakers
    Oil-filled switches
    An insulator and arc extinguishing agent in switchgear and circuit breakers
    X-ray equipment

    Shell Diala S2 ZX-A Performance Features:

    Highly resistant to oxidative degradation

    Resists the formation of oxidation products that can reduce the ability of the oil to insulate and cool electrical windings

    Rapid heat transfer properties
    An essential quality in electrical insulating systems
    Compatible with construction materials
    Compatible with all common construction materials used in electrical systems.
    Outstanding low temperature properties
    Without the need for pour point depressants
    Shell Diala S2 ZX-A Oils do not contain PCB's

    Shell Diala S2 ZX-A Performance Specifications:

    Shell Diala Oil A meets the ANSI/ASTM/NEMA Type I requirements without the addition of an oxidation inhibitor.

    Shell Diala S2 ZX-A Health & Safety:

    Shell Diala S2 ZX-A Oils are unlikely to present any significant health or safety hazard when properly used in the recommended application, and good standards of industrial and personal hygiene are maintained.

    For further guidance on Product Health & Safety refer to the appropriate Shell Product Safety Data Sheet

    Shell Diala S2 ZX-A Storage Precautions:

    The critical electrical properties of Shell Diala S2 ZX-A Oils are easily compromised by minute concentrations of contaminants. Typically encountered contaminants include moisture, particulates, 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 air-tight seals. It is further recommended that electrical insulating oils be stored indoors in climate-controlled environments.
