Production Technology
Premium Iron Core Selection:We strictly select high-permeability, low-loss cold-rolled silicon steel sheets. Through multiple cutting and stacking processes, stable magnetic circuit performance is achieved.
Precision Winding Process:High-purity copper wires are evenly wound according to designed turns with compact and neat arrangement, ensuring consistent inductance across units.
Thorough Insulation Treatment:Multiple layers of insulating materials are applied for inter-winding and ground isolation. Featuring a high temperature resistance class, it effectively prevents insulation breakdown and short circuits.
Vacuum Impregnation & Curing:The entire unit undergoes vacuum pressure impregnation and curing, which strengthens the mechanical strength of windings and improves moisture resistance and heat dissipation performance.
