Description
Indo-Tech Power Transformer – Medium Range, 5MVA to 31.5MVA
The Indo-Tech Power Transformer series covers the medium power range from 5MVA/33KV to 31.5MVA/132KV, manufactured at the state-of-the-art Kancheepuram facility of Indo Tech Transformers Limited (ITTL). These are oil-immersed, naturally cooled transformers designed for substation, industrial, and utility applications where reliable high-voltage step-up or step-down conversion is critical. ITTL has produced over 66,000 transformers to date, with units currently in service across substations and industries in India and international markets.
Available Configurations
- Two Winding Transformers – Standard HV/LV configuration for grid-to-industrial feeder applications
- Three Winding Transformers – Dual secondary outputs from a single primary; ideal for substations supplying two voltage levels
- Auto Transformers – Compact, efficient design for voltage ratio applications with a common winding
