Built around the confirmed duty
The official source distinguishes this design from conventional power transformers by identifying overload, harmonic current and voltage, high-frequency transient overvoltage and undervoltage as key operating considerations. The source describes copper wire or foil windings, AFA insulation, lower core flux density, side cable exits and temperature, pressure, gas and oil-level protection.
Working principle
The oil-immersed transformer converts power between the renewable-energy equipment and the collection or grid system, with the magnetic and insulation design reviewed for converter-driven operating conditions.
New-energy equipment selection requires the rated electrical or process duty, operating profile, grid or process interface, site climate, thermal management, communication and destination certification.
Core features
- Designed for renewable-system overload and harmonic duty
- Lower source-described core flux density margin
