South Africa has Africa's most developed manufacturing, mining and automotive industries. Years of load-shedding have made backup power, solar and inverter systems mainstream, so demand for UPS and inverter transformers, chokes and harmonic reactors is strong.
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 packed for export to buyers in Johannesburg, Ekurhuleni, Pretoria and across South Africa.
Built for 230 V single-phase / 400 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 South Africa 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.

Economical voltage conversion where isolation is not required.
Platinum, gold and coal mines in Gauteng, North West and Mpumalanga run pumps, hoists and conveyors.
Typical use: Step-up, step-down and isolation duty from 1 kVA to 1500 kVA.
Load-shedding has driven rapid growth in rooftop solar, battery and inverter systems.
Typical use: Step-up, step-down and isolation duty from 1 kVA to 1500 kVA.
Vehicle plants in Gqeberha, Durban and Pretoria and their suppliers run large production lines.
Typical use: Isolation for robotic welding and machining lines.
Panel builders in Johannesburg and Ekurhuleni supply mining, industrial and commercial projects.
Typical use: Step-up, step-down and isolation duty from 1 kVA to 1500 kVA.
Johannesburg and Cape Town are Africa's largest data-centre markets.
Typical use: Step-up, step-down and isolation duty from 1 kVA to 1500 kVA.
Municipal water utilities and mines run large pumping and dewatering systems.
Typical use: Step-up, step-down and isolation duty from 1 kVA to 1500 kVA.
Many sites in South Africa run on a mix of grid power and diesel generators, with voltage swings and frequent changeovers. Tell us your supply conditions and we design with margin on voltage, temperature rise and duty, so equipment stays protected.
