In heavy manufacturing plants, industrial power transformers are typically installed in on-site substations, electrical rooms near large process lines, or outdoor fenced yards. They step down utility MV/HV feeds to plant distribution voltages that supply large motors, variable-speed drives, furnaces, compressors, welders, and auxiliary systems. Units are positioned to minimize cable runs to major loads while meeting clearance, ventilation, and maintenance access requirements and integrating with switchgear and protection schemes.
