Shell Diala S2 ZX-A

Formerly known as Shell Diala Oils AX


Electrical insulating oils

Shelf life: 1 year (from DOM)

Shell Diala Oils  are electrical insulating fluids, for use in electrical systems where rapid heat transmission and high oxidation stability are required.
They are highly refined naphthenic mineral oils with natural low pour point characteristics.
Shell Diala Oil A is intended for use where normal oxidation resistance is required.

Applications:

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

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

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

Performance Specifications:

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

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

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.
