GNEE's 800 kVA Oil Immersed Transformer installed in a heavy industrial plant, powering production machinery.
Design Features of 800 kVA Oil Immersed Transformer for Heavy Industry
The 800 kVA Oil Immersed Transformer is engineered to withstand the harsh conditions of heavy industrial environments and handle high-intensity loads:
- Rugged Tank Construction: Uses 5mm thick carbon steel (vs. standard 3mm) for the tank, with anti-corrosion and anti-impact coatings-resisting industrial dust, chemical fumes, and mechanical collisions common in factories or mines.
- High-Load Tolerance: Equipped with thickened copper windings (cross-sectional area ≥120mm²) and a high-density iron core (30Q150 grade silicon steel), enabling it to handle 150% of rated load for 1 hour (critical for industrial peak operations like batch production).
- Enhanced Cooling System: Optimized ONAN (Oil Natural, Air Natural) cooling with extended radiator fins-increasing heat dissipation efficiency by 30% vs. standard models, ensuring stable operation even in high-temperature industrial workshops (up to 50°C ambient).
- Industrial-Grade Protection: Integrates pressure relief valves (for overpressure from load spikes), oil moisture absorbers (to prevent insulation degradation), and high-temperature alarms-reducing failure risks in continuous industrial operation.
Performance Advantages of 800 kVA Oil Immersed Transformer for Heavy Loads
For heavy industrial applications, the performance of 800 kVA Oil Immersed Transformer directly impacts production efficiency and equipment longevity:
Low Energy Loss: Complies with IE3 high-efficiency standards, with no-load loss as low as 850W and load loss at 6200W. For an industrial plant operating 24/7, this translates to annual electricity savings of ~6,500 kWh vs. IE2 models-cutting industrial energy costs.
Stable Voltage for Sensitive Equipment: Features a 5-tap voltage regulator (±2.5% × 2) to maintain secondary voltage stability within ±3%, protecting expensive industrial machinery (e.g., CNC lathes, hydraulic systems) from voltage fluctuations that cause malfunctions.
Long Continuous Operation Life: The sealed oil tank uses high-quality mineral insulating oil (IEC 60296 compliant) with anti-oxidation additives, extending oil replacement cycles to 8–10 years. Core components have a design life of 30+ years-matching the lifespan of industrial facilities.
Low Maintenance Requirements: Equipped with oil level sight glasses and pressure gauges for easy visual inspection; only requires annual oil sampling and cleaning-minimizing maintenance downtime for industrial production.
