   C. Amorphous Metal Core Transformers
   Key Features: 70-80% lower no-load losses vs. silicon steel
   Best For: Solar farms/24/7 operations (where energy savings justify higher upfront cost)
   Top Brands: Hitachi AMDT, TBEA amorphous series
   Technical Specs:
   Core loss: 0.2W/kg (vs 1.3W/kg for CRGO)
   Payback period: 3-5 years in high-usage scenarios
   Typical applications: Utility substations, renewable energy
