Shell Diala Oil A & AX

Shell Diala Oil A & AX
Electrical insulating oils - Dầu cách điện máy biến áp, máy biến thế Shell - cao cấp
Shell Diala Oils A and AX 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, whilst Shell Diala Oil AX is recommended for more severe service applications requiring greater oxidation resistance

Applications
Shell Diala Oils A & AX 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 Oils A & AX 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.
Shell Diala Oil AX is an oxidation inhibited oil and meets Type II requirements.

Health & Safety

Shell Diala Oils A & AX 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 Oils A & AX 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.
