Our 4-Step Quality Protocol

Every transformer produced in our 3,500 sq.ft Pune facility undergoes multi-stage quality inspections to ensure zero-defect delivery for international markets.

01

Raw Material Inspection

100% testing of high-grade CRGO core steel, high-purity copper magnet wire, and premium epoxy resin casting materials prior to production.

02

Precision Core Winding

Toroidal winding executed on automated precision machinery to guarantee exact turns ratio, uniform wire tension, and minimum physical stress.

03

Vacuum Impregnation & Potting

Advanced vacuum pressure impregnation and resin potting to eliminate air voids, enhancing dielectric strength and mechanical shock resistance.

04

100% Electrical Routine Testing

Every batch undergoes ratio testing, polarity check, excitation current measurement, phase angle testing, and high-voltage dielectric withstand test.
