Four Families, Every Application
Oil-Immersed Power & Distribution
Conventional and sealed ONAN / ONAF / OFWF cooled, oil-immersed single and three phase, 50/60 Hz aluminium or copper double-wound, continuous-duty transformers from 5 kVA to 10,000 kVA, up to 33 kV class.
Energy Efficient / Star-Rated
BEE star-rated, low-loss distribution transformers engineered for lifetime energy savings — plus customer-specific designs such as auxiliary-use, mining and dual-ratio transformers.
Special Purpose & Inverter-Duty
Application-engineered units for solar plants and wind mills, inverter-duty and auxiliary transformers, Scott-T, dual vector group, Zig-Zag, NGR-coupled, isolation / ultra-isolation and furnace-duty transformers up to 4 MVA.
Dry Type (VPI)
VPI-technology dry type, AN cooled, three phase, 50/60 Hz copper double-wound continuous-duty transformers from 5 kVA to 2,000 kVA — ideal for indoor substations and fire-sensitive sites.

Solar Plants & Inverter-Duty
Step up inverter output to distribution and grid voltages with transformers purpose-designed for solar application — inverter-duty units that handle harmonic-rich PV waveforms, plus auxiliary transformers for plant loads. Melcon designs to each project's vector group, impedance and tap-changing requirements.

Substations & Distribution Networks
Conventional and sealed oil-immersed distribution and power transformers up to 10 MVA, 33 kV class serve utilities, DISCOMs and industrial substations. Energy-efficient star-rated designs cut lifetime losses, while anti-theft and dual-ratio variants solve field-specific challenges.

Industrial & Special Applications
From furnace-duty transformers for steel and casting plants to isolation transformers protecting sensitive equipment, Scott-T units for heat tracing, and transformers for mining, railways and wind mills — Melcon engineers customer-specific designs that have become industry benchmarks, backed by ISO 9001 quality systems.

Frequently Asked Questions
Transformers are manufactured by Melcon, the Saatvik Group's ISO 9001 certified transformer company. Melcon has over 25 years of experience as a manufacturer and exporter of power and distribution transformers up to 10 MVA, 33 kV class, alongside fully customized designs.
An inverter-duty transformer steps up the output of solar inverters to distribution or grid voltage while withstanding the harmonic content and switching stresses of PV waveforms. Melcon designs solar-application transformers with the vector groups, impedances and multiple LV windings that utility-scale plants require.
Oil-immersed power and distribution transformers span 5 kVA to 10,000 kVA up to 33 kV class, with ONAN, ONAF and OFWF cooling. Dry type VPI transformers cover 5 kVA to 2,000 kVA, and furnace-duty units range up to 4 MVA. CT/PT sets are available in 11 kV and 33 kV class.
Yes. Melcon manufactures customer-specific designs including auxiliary-use, mining, dual-ratio, servo voltage stabilized, Scott-T, Zig-Zag, NGR-coupled, anti-theft, isolation / ultra-isolation and railway transformers — all built to the relevant IS, IEC, BIS and international standards.
