Shell Diala Oil BG
Gas absorbing transformer oil
Shell Diala Oil BG is a light mineral oil specially refined for electrical applications.
Applications
Shell Diala Oil BG is primarily intended for use in transformers as:
a coolant, to dissipate the heat generated when the transformer is on load
a dielectric, to insulate the windings by replacing air, or other gases, between the conductors and in any voids present in solid insulating materials
an arc extinguishing agent, to quench the spark between the opening contacts when tap changing on load
an insulator and arc extinguishing agent in switchgear and circuit breakers
an insulator in bushings
an insulator in automotive ignition coils
Performance Features
Effective and efficient heat transfer
Low viscosity fluid circulates easily in systems providing effective cooling and heat transfer properties
Highly resistant to oxidative degradation
Resists the formation of harmful acids and sludge. Long oil service life.
Outstanding low temperature properties
Without the need for pour point depressants
Shell Diala Oil BG does not contain PCB’s
Performance Specifications
Shell Diala Oil BG complies with the requirements of the following specifications:
BS 148 (1984) Type 1
IEC 296 (1982) Class 1
Health & Safety
Shell Diala Oil BG is 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 Oil BG is 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.
