HJ-AMT-O Series Amorphous Alloy Transformer – Oil

Name: HJ-AMT-O Series Amorphous Alloy Transformer – Oil
Brand: HJATIS

The HJ-AMT-O Series is an oil-immersed amorphous-alloy distribution transformer for system voltages up to 35 kV and catalogue ratings from 50 kVA to 2500 kVA. Its amorphous-alloy core is intended to reduce no-load losses compared with a conventional silicon-steel design. The hermetically sealed corrugated tank limits contact between the insulating oil and the atmosphere.
