High Grade Uninhibited Transformer Oil – Equivalent to Shell Diala B

Our High Grade Mineral Uninhibited Transformer Oil is a premium insulating oil refined to meet IEC 60296:2003 standards. It is suitable for use in:

• Power and distribution transformers
• Submersible electric motors and pumps
• Oil-filled circuit breakers and switches
• X-ray and other high-voltage equipment

Key benefits include:

• Excellent dielectric strength: Minimum breakdown voltage of 30 kV for reliable insulation.
• Low sulphur content: Free from DBDS with very low total sulphur to prevent copper corrosion and extend equipment life.
• Enhanced thermal performance: Low viscosity for efficient heat transfer and system reliability.
• Outstanding oxidation stability: Resists sludge and acid formation to prolong oil and equipment lifespan.
• Safe handling: High flash point of 135°C reduces evaporation and improves safety.

Technical specifications:

• Breakdown voltage: ≥ 30 kV
• Specific gravity @ 15.6°C: 0.898
• Kinematic viscosity @ 40°C: 12.00 cSt
• Kinematic viscosity @ -30°C: 1800 cSt
• Flash point (COC): 135°C
• Pour point: -40°C
• Appearance: Clear

This oil is compatible with applications specifying Shell Diala B or similar uninhibited mineral oils, meeting strict industry requirements for long-term performance.
