HJ-AMT-D Series Amorphous Alloy Transformer – Dry

Name: HJ-AMT-D Series Amorphous Alloy Transformer – Dry
Brand: HJATIS

The HJ-AMT-D Series is a dry-type 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, while the windings use vacuum-cast epoxy resin encapsulation. Cooling modes include AN/AF and insulation classes F or H.
