Tanzania's manufacturing, mining and agro-processing sectors are growing steadily, and Dar es Salaam is East Africa's second gateway port. Factories and mines deal with grid fluctuation and generator backup, which makes robust transformers and chokes a priority.
VA Electricals designs and manufactures buck boost 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 Dar es Salaam, Arusha, Mwanza and across Tanzania.
Built for 230 V single-phase / 400 V three-phase, 50 Hz, with the buck or boost amount chosen to bring your supply to the equipment's rated voltage.
A buck boost transformer raises (boosts) or lowers (bucks) the supply voltage by a small amount so equipment receives the voltage it is designed for. Because it only handles the correction voltage, it is far smaller and more economical than a full isolation transformer for the same load.
For sites in Tanzania where the supply sits a little above or below what equipment is rated for, a buck boost transformer corrects the voltage economically, without a full-size transformer.
Lowers a high supply voltage to protect equipment rated for a lower voltage.

Designed around your measured supply range and load.
Agro-processing, beverage and edible-oil plants run process and packaging lines.
Typical use: Keeping refrigeration and process motors at rated voltage.
Gold and mineral mines around Mwanza and Geita run pumps, crushers and conveyors.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Cement plants around Dar es Salaam and Tanga run kilns, mills and large motors.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Panel builders in Dar es Salaam supply industrial and commercial projects.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Off-grid and commercial solar systems need inverter and power-conversion equipment.
Typical use: Bucking or boosting supply voltage by a small amount to match equipment.
Telecom towers and data facilities rely on inverter and UPS backup.
Typical use: Holding voltage steady at remote equipment sites.
Many sites in Tanzania 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 buck boost transformers at its works in Pune, India and supplies buyers across Tanzania, including Dar es Salaam, Arusha, Mwanza, Dodoma, Morogoro.
Yes. Units are built for the 230 V single-phase / 400 V three-phase, 50 Hz supply used in Tanzania, with the buck or boost amount chosen to bring your supply to the equipment's rated voltage.
When the supply only needs a small voltage correction and isolation is not required. A buck boost unit handles only the correction voltage, so it is smaller, lighter and lower in cost for the same load.
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 transformers up to 200 kVA.
Shipped by sea from Nhava Sheva to Dar es Salaam, 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.
Share your voltages, rating and quantity. Our engineers will send a technical offer for supply to Dar es Salaam, Arusha, Mwanza or anywhere in Tanzania.
