Our Rigorous Quality Assurance Process
Technical points： * Strict inspection of Silicon Steel and Electromagnetic Wires. Insulation oil dielectric strength and moisture analysis.
Technical points： * Winding tension and alignment monitoring. Core stacking precision and tightening torque checks. Active part drying and vacuum process verification.
Technical points： * Full routine tests: Resistance, Ratio, and Phase. High-voltage dielectric and insulation integrity verification.
Technical points： * Structural integrity and paint finish inspection. Packaging durability and technical documentation audit.
"All tests are performed in accordance with IEC 60076 and IEEE standards."
