Kolkata anchors East India's industry. Howrah's engineering units, the Dankuni and Uluberia industrial parks, and the Durgapur and Haldia belts serve steel, power, port and process industries across the region.
VA Electricals designs and manufactures dry-type three-phase isolation, step-up and step-down transformers at its works in Bhosari, Pune. Every unit is built to your voltages and rating and tested in-house, then delivered by road to customers in Howrah, Dankuni, Taratala and across Kolkata.
Built for 230 V single-phase / 415 V three-phase, 50 Hz, with primary and secondary voltages to suit your equipment, including step-up and step-down ratios.
A three-phase isolation transformer provides galvanic isolation between the line and load windings, shielding equipment from transients, spikes, DC leakage and EMI/RFI noise. VA Electricals builds dry-type, naturally air-cooled three-phase transformers with copper or aluminium windings from 1 kVA to 1500 kVA, for isolation, step-up and step-down duty.
For plants in Kolkata running CNC machines, process equipment or imported machinery, a three-phase isolation transformer protects sensitive loads from supply transients and lets equipment run at its rated voltage.
Galvanic isolation that shields sensitive equipment from transients, spikes and EMI/RFI noise.
View product detailsRun imported or export machinery at its rated voltage, whatever the local supply.
Economical voltage conversion where isolation is not required.
Durgapur and the Howrah engineering belt serve steel, foundry and heavy-engineering industries.
Typical use: Step-up and step-down duty for furnaces, test benches and imported machines.
Haldia hosts refinery, petrochemical and port-based process plants.
Typical use: Step-down and isolation duty for process plant equipment.
Panel builders in Howrah and Taratala supply projects across East India.
Typical use: Step-up, step-down and isolation duty from 1 kVA to 1500 kVA.
Electronics and IT firms in Salt Lake Sector V need dependable UPS power.
Typical use: Isolated test and production supplies for electronic equipment.
Food processing, tea and FMCG plants run packaging and process lines.
Typical use: Step-up, step-down and isolation duty from 1 kVA to 1500 kVA.
Coal and mineral operations in the eastern belt run conveyors, pumps and crushers.
Typical use: Step-up, step-down and isolation duty from 1 kVA to 1500 kVA.
Plants in Kolkata see summer heat in panel rooms, monsoon humidity and supply fluctuations. Share your duty cycle and ambient conditions, and we design the rating, insulation and construction to suit.
