Precision-Engineered Enameled Flat Wire for Superior Electrical Performance

As a leading component in advanced electrical systems, Enameled Flat Wire is an indispensable winding material for a vast array of equipment, including power and Transformadores de subestación, generators, electric motors, reactors, and many other critical electrical devices. At Evernew Transformer, we pride ourselves on manufacturing premium-grade enameled flat wire designed to deliver unparalleled performance and reliability.

Our manufacturing process begins with high-purity oxygen-free copper rod or aluminum rod, precisely drawn through a rectangular die to achieve the desired dimensions. This conductor is then meticulously coated with multiple layers of high-performance insulating varnish, formulated for various temperature resistance levels. Following a controlled baking and curing process, the conductor and the durable insulation layer form a tight, robust bond, ensuring exceptional mechanical strength and superior electrical insulating properties. This meticulous engineering makes our rectangular enameled wire ideal for demanding applications requiring high fill factors and excellent heat dissipation.

Standards & Certifications

Our Enameled Flat Wire rigorously adheres to international quality and performance benchmarks, ensuring compatibility and reliability across global markets:

• GB/T7095-2008 / IEC
• IEC60317 Series

This compliance guarantees that our insulated magnet wire meets stringent industry specifications for your peace of mind.
