Heavy-Duty Electricals for Steel & Mining
Captive substations, harmonic mitigation systems & rolling mill drive MCCs engineered for extreme demand swings & arc furnace loads.
Heavy-Duty Infrastructure Built for Severe Swings & Arc Furnace Harmonic Distortion
Steel and metal processing plants run some of the harshest electrical loads in industry: extreme demand swings, severe harmonic distortion from arc furnaces and rectifiers, and continuous heavy-duty operation with little tolerance for unplanned downtime. DEC's execution record includes major 66/11kV switchyards for Jindal SAW Ltd in Gujarat, plant electricals for Sonar Casting in Durgapur, 33/11kV mining substations for Adani Mining, and custom MCCs and harmonic mitigation systems for ISGEC Heavy Engineering and Magnum Steel.
Process Electrification & System Architecture
Captive High-Voltage Substations
66kV & 132kV heavy-duty outdoor switchyards engineered for high fault levels and inductive mill loads.
Harmonic Filter & PFC Capacitor Banks
Dynamic harmonic mitigation systems designed specifically to keep arc furnace harmonics from destabilizing power quality.
Rolling Mill Drive MCCs & VFDs
Trisquare heavy-duty Motor Control Centres custom-built for high-torque rolling mill & furnace auxiliary drives.
Mining & Metal Processing Distribution
33kV/11kV primary distribution transformers and POLYVION heavy-armoured cabling networks.
