Amorphous Alloy Transformers
Cores wound from amorphous alloy ribbon instead of stacked silicon steel, cutting no-load loss sharply. No-load loss is paid for every hour the transformer is energised, so on a lightly loaded distribution feeder this is where the annual energy bill is actually decided.

VPI Dry-Type Transformers
Vacuum Pressure Impregnated dry-type transformers with Class F/H insulation. Windings are impregnated under vacuum and pressure rather than resin-encapsulated, giving good heat dissipation and overload behaviour at a lower cost than a cast resin unit of the same rating.

Cast Resin Dry-Type Transformers
Windings vacuum-cast in epoxy resin: flame-retardant, self-extinguishing, maintenance-free and free of oil. Class F/H insulation. The default choice wherever the transformer has to stand inside the building — hospitals, airports, high-rises, metro lines and data centres.
