Core Series Features
High-Dielectric Strength Transformer Oils
Standards: IEC 60296, ASTM D3487
Our transformer oils are deeply hydro-refined, providing exceptional dielectric strength and oxidation stability. These fluids serve a dual purpose as both an electrical insulator and a heat-transfer coolant within electrical transformer tanks.
- Excellent Dielectric Properties: Minimizes electrical losses and prevents arcing, ensuring the long-term integrity of the transformer windings.
- Superior Oxidation Stability: Resists the formation of acidic sludge and deposits, which are the primary causes of transformer overheating and insulation failure.
- Low Viscosity: Ensures rapid and efficient heat dissipation from the transformer core and coils to the cooling fins/radiators.
- Grade 25 vs. Grade 45: Grade 25 is suitable for standard temperate climates, while Grade 45 is formulated for extreme cold environments, offering superior fluidity at sub-zero temperatures.
Applications & Usage Scenarios
- Power Transformers: Used in oil-filled power and distribution transformers for high-voltage power transmission grids.
- Electrical Switchgear: Suitable for oil-filled circuit breakers, switches, and other high-voltage oil-filled electrical apparatus.
- Cold Climate Operation: Use Grade 45 for outdoor installations in arctic or high-latitude regions to maintain transformer cooling efficiency even in severe frost.
Precautions & Maintenance Guidelines
- Moisture & Contamination: Dielectric strength is extremely sensitive to moisture and particulate contamination. Keep containers hermetically sealed and use professional filtration/dehydration units when filling or topping off transformer tanks.
- Strict Cleanliness: Ensure all hoses, pumps, and tools used for handling transformer oil are clean, dry, and dedicated to electrical oil service only to avoid cross-contamination.
- Periodic Testing: Implement a regular testing schedule for Dissolved Gas Analysis (DGA), moisture content, and dielectric breakdown voltage to identify potential insulation issues before failure occurs.
