The 100kVA three phase dry-type step-down isolation transformer<\/a> is a high-capacity industrial power transformer engineered for reliable power distribution, electrical isolation, and voltage conversion in demanding industrial and commercial environments. Designed to support three phase power systems, this dry-type isolation transformer commonly steps down 480V primary voltage to 208Y\/120V secondary voltage, while also supporting a wide range of other standard industrial voltages for global applications.<\/p>\n

As a 100 kVA isolation transformer, this unit is ideally suited for medium-to-large industrial loads where stable voltage, safety, and long-term reliability are critical. The dry-type, oil-free construction makes it suitable for indoor installations and applications requiring enhanced fire safety, low maintenance, and environmentally friendly operation.<\/p>\n
