Three Decades of Powering India's Growth
From a single transformer workshop in Hyderabad to a fully integrated power equipment manufacturer — our journey is built on engineering precision, uncompromising quality, and a commitment to keeping the lights on across India.
Founded on Engineering. Grown on Trust.
NSM Power Systems was established in [YEAR] by [Founder Name], a power systems engineer with a vision to build world-class electrical equipment in India. Starting with a modest 5,000 sq. ft. workshop and a team of 12 engineers, the company manufactured its first distribution transformer in [YEAR].
Over the following decades, NSM expanded steadily — adding product lines, investing in state-of-the-art CNC winding machines and vacuum pressure impregnation plants, and earning type-test approvals from CPRI for its growing range of transformers and switchgear.
Today, NSM Power Systems operates from a [X] sq. ft. integrated manufacturing campus in [Location], Hyderabad, with an annual production capacity of [X] MVA. Our products power substations, industrial plants, renewable energy projects, and critical infrastructure across [X]+ states in India.

Built to Build the Best
Our integrated manufacturing campus in Hyderabad houses dedicated bays for transformer winding, core cutting, tank fabrication, panel assembly, and high-voltage testing — all under one roof.
CRGO Core Cutting
Precision step-lap core cutting lines for CRGO and amorphous core materials, minimising no-load losses.
CNC Coil Winding
Automated CNC winding machines for HV and LV coils, ensuring consistent turn count and insulation placement.
Vacuum Pressure Impregnation
VPI plant for dry-type transformer insulation, delivering Class F and Class H insulation systems.
Tank Fabrication & Painting
In-house tank fabrication with shot blasting, epoxy primer, and polyurethane topcoat finishing.
High-Voltage Test Bay
Dedicated HV test bay for routine and type tests including applied voltage, induced voltage, and impulse tests.
Panel Assembly & Wiring
Climate-controlled panel assembly bay for MV switchgear, LV switchboards, and control panels.
Tested. Certified. Trusted.
Every product that leaves our facility has been manufactured under a certified quality management system and tested to the applicable IEC, IS, or IEEE standard.
Quality Policy
NSM Power Systems is committed to designing and manufacturing electrical equipment that consistently meets or exceeds customer requirements and applicable standards. We achieve this through a culture of continuous improvement, rigorous in-process inspection, and independent third-party type testing at CPRI-accredited laboratories.
