Product Q&A
Q:Why can the partial discharge level of this product be kept below 5pC?
A:
The coils undergo vacuum impregnation, allowing the varnish to fully penetrate all microscopic gaps between layers and turns under vacuum pressure, eliminating air bubbles and preventing partial discharge, thus ensuring long-term operational reliability.
Q:What is the practical significance of Class C insulation (220degree C)?
A:
Class C is the highest thermal class for dry-type transformers, allowing long-term operation at 220 degree C. It provides strong overload capacity, higher safety during short-term emergency overloads, and extended service life, especially suitable for high-temperature environments or applications with significant load fluctuations.
Q:How does the 3D rolled core achieve low noise?
A:
The 3D rolled core has no joints, smooth magnetic paths, uniform and minimal magnetostriction deformation, plus symmetrical three-phase magnetic paths with balanced electromagnetic forces, fundamentally reducing electromagnetic vibration and noise.
