Distribution Transformers

Core type distribution transformer for industrial application is available in 3 or 1 phase version with primary voltages of up to 33 KV and secondary voltages ranging from 433 to 11000 V. The capacity range is up to 10000 KVA. We manufacture single phase distribution transformers and three phase distribution transformers.Transformers are available with 'Tap Changer' options as well as "Off Circuit Manually Operated" and "On Load Tap Changer" (OLTC) with AVR and RTCC panel.Prime quality, low loss, high permeability "Cold Rolled Grain Oriented" silicon steel is used for core to achieve low no load losses.Electrolytic copper with insulating paper multi covered round wires and strips are used for both the primary and secondary windings to achieve low load losses.Copper foil winding technology is used for high current sections to achieve following advantages:Sustaining short circuit forces without any distortion in low voltage and high current windingsHot spot in LV windings regulatedNo transposition, stray losses are minimal. Thus total copper losses are also further reducedTotal copper losses reduced vis-a-vis standard losses. Thus heat dissipating area also reducesONAN cooling with conventional pressed steel radiators or corrugated walls are provided for special Transformers ONAF cooling with fans for specific requirement. The terminal arrangement for primary and secondary voltage are decided as per site requirements. Low viscosity transformer oil is provided with in numerous superior grades for specific usage.
