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 three-phase line, input and output chokes 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.
Rated for 230 V single-phase / 400 V three-phase, 50 Hz systems, with inductance and current rating matched to your drive.
A three-phase line choke is an inductor connected in series with a drive or rectifier. On the input side it reduces harmonic current and protects the drive from line spikes and notching. On the output side it limits dv/dt and protects motors fed through long cables.
For drive users in South Africa, a line choke on the input or output of a VFD reduces harmonics, limits inrush and protects the drive and motor from spikes and long-cable effects.
Reduce harmonic distortion and electrical noise on drive and rectifier supplies.

Platinum, gold and coal mines in Gauteng, North West and Mpumalanga run pumps, hoists and conveyors.
Typical use: Chokes on conveyor and crusher drives.
Load-shedding has driven rapid growth in rooftop solar, battery and inverter systems.
Typical use: Input and output chokes for VFDs and drives.
Vehicle plants in Gqeberha, Durban and Pretoria and their suppliers run large production lines.
Typical use: Input and output chokes for VFDs and drives.
Panel builders in Johannesburg and Ekurhuleni supply mining, industrial and commercial projects.
Typical use: Input and output chokes in VFD and drive panels.
Johannesburg and Cape Town are Africa's largest data-centre markets.
Typical use: Input and output chokes for VFDs and drives.
Municipal water utilities and mines run large pumping and dewatering systems.
Typical use: Drive chokes for large pump motors.
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.

Yes. VA Electricals manufactures three-phase line, input and output chokes at its works in Pune, India and supplies buyers across South Africa, including Johannesburg, Ekurhuleni, Pretoria, Durban, Dube TradePort.
Yes. Units are built for the 230 V single-phase / 400 V three-phase, 50 Hz supply used in South Africa, with inductance and current rating matched to your drive.
An input choke sits between the supply and the drive to reduce harmonics and protect against line spikes. An output choke sits between the drive and motor to limit dv/dt and protect motors on long cable runs.
VA Electricals operates an ISO 9001:2015 certified quality management system and holds MSME ZED Bronze certification. Its products carry CE conformity under the Low Voltage Directive 2014/35/EU, covering chokes and reactors up to 1000 A.
Shipped by sea from Nhava Sheva to Durban, with onward delivery and air freight for urgent needs.
Yes. Tell us about voltage fluctuations, generator use and ambient temperature. We build in margin on voltage, temperature rise and duty so units stay reliable on unstable supplies.
