OCB – Oil Circuit Breaker
Many older substations still run on oil circuit breakers. We service and overhaul them, and upgrade them to VCB when replacement is due.

- OCB to VCB retrofit
ACB – Air Circuit Breaker
The main protection device on the LT side, used as the incomer for main LT panels and PCCs to guard against overload and short circuit.

- Microprocessor release units
- Supply, installation & servicing
33/11 kV Substation
Turnkey substations that step 33 kV grid supply down to 11 kV for industrial parks, large plants, campuses and solar projects.
- Power transformer & switchyard
- Isolators, LAs, CT/PT & breakers
- Control & relay panels, battery & charger
- Earthing, structure & civil works
Step-Up Transformer
Raises voltage for efficient power transmission. Essential for solar plants to evacuate generated power into the 11 kV / 33 kV grid.
- Inverter-duty transformers for solar
- LV to 11 kV / 33 kV step-up
- Oil-cooled (ONAN) & dry type
- Low-loss, energy-efficient cores
Step-Down Transformer
Brings high grid voltage down to usable levels for your factory, building or campus, so that equipment runs safely.
- Distribution transformers 11 kV / 433 V
- Power transformers 33 / 11 kV
- With or without OLTC / OCTC
- Copper & aluminium winding options
Manufacturing & Maintenance
We build it right and keep it running right, so your power system stays safe, efficient and compliant for years.
🏭 Manufacturing & Installation

Frequently Asked Questions
What is the difference between an HT panel and an LT panel?
An HT panel works on high voltage (11 kV or 33 kV) coming from the grid and protects the incoming supply and transformer. An LT panel works on low voltage (415 V) after the transformer and distributes power to your machines, lighting and other loads.
Should I choose a VCB or an OCB?
For new installations, a VCB is the better choice. It is safer, needs very little maintenance and has no oil fire risk. OCBs are an older technology; if you already have one, we can service it or retrofit it with a VCB.
What is the difference between a step-up and a step-down transformer?
A step-up transformer increases voltage, for example from solar inverter output up to 11 kV or 33 kV to feed the grid. A step-down transformer reduces voltage, for example from 11 kV to 433 V, so a factory or building can use it.
Do you provide a complete 33/11 kV substation on turnkey basis?
Yes. We handle design, power transformer, switchyard equipment, control & relay panels, earthing, structures, erection, testing and commissioning as a complete turnkey package.
How often should a transformer be maintained?
Basic checks (oil level, silica gel, temperature) should be done every month, and oil BDV testing with a detailed inspection at least once a year. An AMC with us covers all of this on a fixed schedule.
Do you offer AMC for panels and transformers installed by other companies?
Yes. We provide maintenance and AMC for HT/LT panels, breakers and transformers regardless of who installed them.
