Installation & Maintenance

Optimal performance guidelines:

1. Maintain minimum 500mm clearance for airflow

2. Verify oil dielectric strength ≥45kV/2.5mm annually

3. Perform infrared thermography scans quarterly

4. Check bushing torque values (35N·m ±10%) during commissioning

5. Monitor partial discharge levels biannually

Compliance Standards

Meets international requirements including:

• IEC 60076 for power transformers/reactors

• IEEE C57.12.00 for liquid-immersed equipment

• EN 50588-1 for medium-power transformers

• IEC 61000-3-12 for harmonic emissions
