Технический обзор
Industrial Isolation & Voltage Conversion Solutions
Isolation transformers decouple primary and secondary electrical circuits to eliminate common-mode noise, suppress voltage transients, and establish clean neutral grounding for sensitive industrial and commercial loads.
Featuring Class H H-grade insulation (180°C), dry-air cooling, and custom primary/secondary voltage ratios (690V, 480V, 440V, 415V, 380V, 240V, 220V, 208V, 110V), XinHuan isolation transformers deliver reliable, long-life performance in factories, medical facilities, and energy storage systems.
