About the company

Two decades of
winding copper
by hand.

Niranjan Enterprises is a family-run transformer manufacturer in Kothrud, Pune. We specialise in custom-wound isolation, power, toroidal, ferrite and current transformers — every one assembled, tested and signed off on our own bench.

Founder & Proprietor
Bhaskar Dubule

Established Niranjan Enterprises in 2003 after eleven years of industrial transformer experience. Still personally signs off on every final inspection.

Our story

Built one coil at a time, since 2003.

Niranjan Enterprises started on a workbench and a CNC winder, with a simple idea: transformers should be specified to the load, not the other way around. Too much equipment fails because it's been fitted with an off-the-shelf part that doesn't quite match the duty.

Twenty-two years on, that philosophy still shapes every quote we send. Our proprietor Mr. Bhaskar Dubule spent eleven years in the industry before founding the company — long enough to know which shortcuts cost you later.

Today we manufacture six families of transformers — isolation, three-phase power, single-phase power, current, toroidal and ferrite-core — across a range of capacities from a few VA to 25 KVA and beyond. Every unit leaves our workshop logged, tested and serial-stamped.

Infrastructure

Compact shop,
industrial capability.

Three CNC winders, two manual winders, three assembly stations and a test bench — enough to deliver a serious run without losing the one-at-a-time care.

Milestones

A few dates that matter.

2003

Niranjan Enterprises founded

Bhaskar Dubule opens the workshop in Kothrud, Pune after eleven years of industrial transformer experience.

2008

First CNC winder added

Precision turn counting opens up tighter-tolerance isolation and current transformer work.

2014

Six product families

Lineup settles at isolation, power (single & three-phase), current, toroidal and ferrite-core.

2020

Third CNC winder & expanded QA

Shop capacity grows while the test-bench regime tightens — every serial logged before dispatch.

Today

Still building one at a time

Small batches, bespoke specs, direct conversations with the engineers who wind them.

What we stand for

Three commitments we don't
trade against price.

Honest specification

We won't oversell a KVA rating or skimp on insulation to meet a price. Quote reflects the real build.

Test before dispatch

Turn resistance, regulation, insulation — logged against the serial printed on the nameplate.

Direct to engineer

Every enquiry is answered by someone who can actually build the thing — usually within a day.
