Power transformers
Dry-type, oil-immersed and amorphous-alloy transformers for distribution and project substations. Compare construction, capacity, voltage ratio and cooling options.
HJ-AMT-D Series Amorphous Alloy Transformer – Dry
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.

HJ-AMT-O Series Amorphous Alloy Transformer – Oil
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.
