HFCL
Telecom & optical fibre
Voltage stabilisation for HFCL's Gurugram operations — resolving the supply fluctuation that was disrupting equipment, so the site runs without interruption.

Servo Stabilizer Manufacturer · Gurugram
Stable power for Gurugram's lines and networks.
From Udyog Vihar export units to the IMT Manesar automotive belt, Voltaire supplies servo voltage stabilizers and isolation transformers to Gurugram directly from our own factory in Uttar Pradesh — no Haryana distributor in between.

Trusted by Gurugram operations.
Gurugram is home to some of the most uptime-sensitive operations in North India. HFCL is one of the organisations that relies on Voltaire-stabilised supply here.
Reference contacts are shared with serious buyers on request.
Factory-direct into Gurugram
Why Gurugram can't rely on the diesel generator.
Gurugram grew faster than its power infrastructure, and for years the answer to unstable supply was a diesel generator. That fallback is shrinking: under the NCR's Graded Response Action Plan (GRAP), diesel generator use is restricted during high-pollution periods, which in practice means much of the winter. Plants and offices are increasingly running on the grid — fluctuations and all.
A correctly sized servo stabilizer is what makes that workable. It holds output voltage within a narrow band whatever the incoming supply does, so robotic welding cells, CNC machines, telecom equipment and server rooms keep running through sags and surges that would otherwise trip them.
We build every unit ourselves at our own factory, about 110 km away by road. Gurugram buyers get the manufacturer directly: sizing from our engineers, load-bank test reports with every unit, and service from the people who built it — not from a reseller relaying messages back to a factory.
On the ground
Where we supply in Gurugram & the Manesar belt
Gurugram's industrial geography runs from the city's older estates out along NH-48 towards Rewari.
01
Udyog Vihar · Phases I–V
Export garment houses and light engineering, where embroidery, cutting and finishing machines are highly sensitive to voltage dips.
02
IMT Manesar
Automotive OEM and tier-1 supplier plants — welding robots, presses and paint shops that cannot afford a line stop.
03
Sector 37 & Pace City
Fabrication, component and tool-room units on shared industrial feeders.
04
Cyber City & corporate sectors
Server rooms, network hubs and building services where the stabilizer sits upstream of the UPS.
05
Sohna Road & Bilaspur
Warehousing, cold chain and logistics parks with large refrigeration and conveyor loads.
06
Dharuhera & Bawal
Auto-component and engineering clusters further along NH-48, supplied on the same delivery run.
Local supply conditions
What Gurugram's grid does to sensitive equipment.
DHBVN · Dakshin Haryana Bijli Vitran NigamGurugram is supplied by Dakshin Haryana Bijli Vitran Nigam (DHBVN). Load across the city has grown far faster than distribution capacity, and industrial estates often sit at the far end of heavily loaded feeders.
1
Low voltage at peak load
Summer demand drags supply below the rated input of drives and controllers, causing nuisance trips and overheating motors.
2
Less DG fallback
With diesel generator use restricted under GRAP during high-pollution periods, equipment has to ride through grid fluctuation instead of avoiding it.
3
Welding & motor transients
Heavy intermittent loads from neighbouring plants on the same feeder inject dips that reach your machines.

Questions from Gurugram buyers
Before you specify.
Do I still need a servo stabilizer if my building has a DG set?
Yes, usually more so. A DG set only helps during outages — it does nothing for low or fluctuating grid voltage, and GRAP restrictions limit when it can run at all. The stabilizer protects your equipment on grid supply every day.
Do you supply IMT Manesar and Bawal as well as Gurugram city?
Yes. We regularly supply along the NH-48 corridor, including IMT Manesar, Dharuhera and Bawal, with installation support from our own engineers.
Will the invoice work for a Haryana-registered company?
Yes. We invoice as an interstate supply from our UP factory, and input-tax credit is available to a Haryana-registered buyer in the normal way.

What IS 9815 Actually Means for Servo Stabilizer Buyers in India — And Why It Matters
IS 9815 is the Bureau of Indian Standards specification for automatic voltage stabilizers — and most stabilizers sold in India do not actually comply with it. Here is what the standard requires, how to verify compliance, and why it matters for your purchase decision.

Oil Cooled vs Air Cooled Servo Stabilizer — Which One Does Your Factory Actually Need?
Most factories get this choice wrong — and end up with a stabilizer that underperforms or fails early. Oil cooled and air cooled servo stabilizers are not interchangeable. Here is exactly when to specify each, and what happens when you get it wrong.
