Applications
Where this transformer is used — connecting the product to real-world industry applications.
Electrolysis
Electrolysis plants — chlorine, aluminum, copper production.
Smelting
Arc furnace and induction furnace transformers for smelting.
Industrial Drives
DC drive power supply — rectifier transformers.
Process Industry
Chemical, steel, mining process — high-current supply.
Plating
Electroplating rectifier transformers.
Quality Proof — 9-Step Manufacturing Process
Every transformer passes through 9 quality-controlled stages, from raw material to shipping. Full traceability with documentation at every step.
Material Inspection
Raw material verification — core steel, copper, oil, accessories checked against certificates before production.
Core Cutting
CNC step-lap core cutting for low-loss grain-oriented silicon steel. Core loss measured before assembly.
Winding
Controlled winding tension, turn-count verification, and insulation paper application for each coil.
Assembly
Core-coil assembly with dimensional checks for fit, clearance, and clamping force.
Vacuum Drying
High-vacuum drying ovens remove moisture from insulation before oil impregnation.
Oil Filling
Filtered insulating oil with breakdown voltage >70kV/2.5mm and moisture <10ppm.
Final Testing
Full routine test per IEC 60076-1 — insulation, resistance, ratio, losses, withstand.
Packing
Sea-worthy export packing with shock-fixed crating for ocean shipping.
Shipping
On-time delivery with documentation — test reports, drawings, manuals in English.
