Medium Voltage (MV) electrical distribution network performance—operating across 3.6kV, 11kV, 24kV, and 33kV systems—depends directly on the precision and quality of original equipment manufacturing (OEM) and customized contract design (ODM). As global energy systems transition toward decentralized renewable generation, heavy industrial electrification, and urban microgrids, standard off-the-shelf switchgear and power equipment frequently fall short of specific site requirements, space limitations, and thermal stress tolerances.
Custom OEM/ODM engineering bridges the gap between general electrical standards and rugged field realities. From tailored busbar arrangements in vacuum circuit breakers (VCBs) to specialized flame-retardant sheath compounds in mining power cables, our manufacturing capabilities cater directly to utility operators, EPC contractors, renewable developers, and heavy industrial plants worldwide.
Our facility operates an integrated manufacturing pipeline spanning core cutting, automated foil winding, structural enclosure fabrication, vacuum pressure impregnation (VPI), and high-voltage routine testing. Below is an overview of our custom production capabilities:
Fixed and drawout ZN63 (VS1) units from 12kV to 24kV, rated 630A to 3150A with 25kA/31.5kA short-circuit breaking capacity and M2 mechanical class endurance.
Single and multi-core copper/aluminum cables rated 3.6/6kV to 33kV. Features flame-retardant, anti-termite, and water-tree resistant cross-linked polyethylene insulation.
Gapless zinc-oxide (ZnO) surge arresters and expulsion drop-out fuse cutouts for 11kV–33kV overhead lines and distribution transformer protection.
Occupying over 103,500 square feet of built-up production area (within a total 131,500+ sq. ft. campus) in Rajkot, Gujarat, our facility brings together advanced metalworking, core assembly, and high-voltage testing under one standardized Quality Management System (ISO certified). Over 70 specialized power engineers and technicians oversee every phase of fabrication.
Unlike conventional round-wire winding methods that introduce mechanical gaps and transposition losses, our automated continuous copper and aluminum foil winding process spreads electrodynamic axial short-circuit forces uniformly across the entire length of the coil.
This structural advantage eliminates localized hot-spots, dramatically lowers thermal gradients during peak load cycles, and dramatically improves coil longevity under frequent through-fault conditions in harsh utility environments.
Quality assurance is backed by our full-scale internal high-voltage test bay. Every unit produced undergoes 100% routine testing prior to dispatch approval, including:

The global medium-voltage apparatus market is undergoing rapid technological evolution driven by decarbonization mandates, grid digitization, and strict environmental regulations. Purchasing managers and EPC specification engineers must take four major industry shifts into account when specifying future equipment:
Sulfur hexafluoride (SF6) has long been used for dielectric insulation in gas-insulated switchgear (GIS), but its high global warming potential (GWP) is prompting global bans. Future OEM procurement focuses on eco-friendly solid-insulated switchgear (SIS) and vacuum interrupters sealed with clean dry air.
Modern MV switchgear and circuit breakers now incorporate continuous thermal sensor arrays, fiber-optic arc detection, and online partial discharge (PD) telemetry. OEM customization increasingly involves pre-installing smart IEDs (Intelligent Electronic Devices) for predictive maintenance.
Renewable power plants experience severe voltage harmonics and daily cyclic loading. OEMs are designing multi-winding step-up MV apparatus equipped with high K-factor harmonic resistance and natural/synthetic ester fluid insulation for maximum fire safety.
To reduce civil installation expenses and footprint, urban utilities and industrial complexes are replacing traditional open-air substations with factory-assembled, weather-tight, vandal-proof compact substations integrating MV switchgear, transformer, and LV boards.
