Distribution transformers 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, three phase distribution transformers and industrial distribution transformers.
These single phase distribution transformers and three phase distribution 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.
These industrial distribution transformers have 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 windings
- Hot spot in LV windings regulated
- No transposition, stray losses are minimal. Thus total copper losses are also further reduced
- Total copper losses reduced vis-a-vis standard losses. Thus heat dissipating area also reduces
ONAN cooling with conventional pressed steel radiators or corrugated walls are provided for special Transformers ONAF cooling with fans for specific requirement. The terminal of these single phase distribution transformers and three phase distribution transformers 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.
