Nepal's industry is concentrated in the Birgunj-Hetauda corridor, the Biratnagar belt and the Kathmandu valley. Hydropower is expanding, but voltage fluctuation remains common, so factories rely on robust transformers, stabilising buck boost units and UPS systems.
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 Kathmandu, Lalitpur, Bhaktapur and across Nepal.
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 Nepal, 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.

Cement and building-material plants in Hetauda and the Terai run mills, kilns and large motors.
Typical use: Chokes on conveyor and crusher drives.
Steel re-rolling and wire mills in Birgunj and Biratnagar run furnaces and heavy drives.
Typical use: Input and output chokes for VFDs and drives.
Food, beverage and noodle plants serve the domestic market.
Typical use: Input and output chokes for VFDs and drives.
Panel builders in Kathmandu and Birgunj supply industry and hydropower projects.
Typical use: Input and output chokes in VFD and drive panels.
Hydropower, solar and off-grid systems need power-conversion equipment.
Typical use: Input and output chokes for VFDs and drives.
Hospitals and diagnostic centres rely on UPS and isolation transformers.
Typical use: Input and output chokes for VFDs and drives.
Factories in Nepal deal with monsoon humidity, voltage fluctuation and frequent changeover to captive generators. Windings are oven-baked for moisture resistance, and ratings are chosen with margin for supply swings.

Nepal is reached by road from India. Consignments travel from Pune through the main border crossings at Raxaul–Birgunj, Jogbani–Biratnagar or Sunauli–Bhairahawa, then on to Kathmandu and other industrial towns.
