3. Key Features

Ultra-low noise with quiet operation: The optimized iron core design and vibration suppression noise reduction circuit result in lower operating noise, making it suitable for high-silence environments such as residential areas, schools, hospitals and office buildings.

Fully sealed, maintenance-free design and oil-free bearing: The fully sealed design prevents the transformer oil from coming into contact with air, providing oxidation resistance, moisture protection, and leak prevention. This eliminates core lift and the need for regular maintenance, resulting in extremely low operating and maintenance costs.

High short-circuit resistance, high mechanical strength of windings and stable insulation design enable it to withstand power surges, load fluctuations and short-circuit voltage, ensuring safe and reliable operation.

Low temperature rise and extended service life: The optimized cooling system provides excellent temperature rise control, effectively slowing down the aging of the insulation, extending the service life of the equipment and improving stability.

Strong environmental adaptability with excellent anti-corrosion, anti-moisture, anti-dust and anti-weather properties, suitable for complex environments such as open spaces, substations, container substations, high mountain areas and coastal areas.
