Three Phase Dry Type Isolation Transformer 480V to 380V
,Dyn11 Open Type Isolation Transformer IP00
,UL Listed Three Phase Dry Type Transformer
Product Overview
This 105kVA three phase isolation transformer is suitable for industrial equipment, machinery power conversion, control systems, and protected indoor distribution points where 480V or 600V primary voltage needs to be converted to 3/N~380V secondary voltage.
Built as an IP00 open type dry-type transformer, the unit uses Class H insulation, copper windings, AN cooling, and a front-accessible terminal layout with 480V and 600V primary tap markings. Its 60Hz design, D/yn11 connection group, 2.5–5% short-circuit impedance, and 620×440×650mm compact structure help buyers match equipment integration, panel installation, and specification review requirements. For projects requiring 105kVA 480V/600V to 380V conversion, this transformer is ready for quotation, drawing confirmation, and technical review.
