Customer needs as the core
Suzhou Daiming Electrical Materials Co., Ltd., is a leading manufacturer of high-quality enameled wires: enameled aluminum wires, enameled copper wires, and enameled copper-clad aluminum wires. Situated on a sprawling 258,333.33 ft² site, our advanced production facility houses 30 state-of-the-art production lines. This robust infrastructure enables us to maintain a stable and high-volume output, ensuring consistent supply to meet global market demands. With strict quality control at every stage, from raw material inspection to final product testing, we uphold the highest industry standards, guaranteeing the durability and performance of our enameled wires.
In modern industrial engineering, electromagnetic performance and structural bundling systems are key factors in system reliability. Enameled magnet wires (copper, aluminum, and copper-clad materials) conduct magnetic fluxes in electric machinery, while enameled coated Galvanized Iron (GI) binding wires provide structural reinforcement under high temperatures, mechanical stress, and corrosive environments.
Enameled Coated GI Binding Wire combines the high mechanical tensile strength of a galvanized zinc-plated iron core with the electrical isolation and chemical corrosion protection of a specialized enamel coating (Polyurethane, Polyesterimide, or Polyamide-imide). This combination provides a stable solution for structural winding alignment in motors, generators, and heavy transformers.
The durability of enameled wire relies on the adhesion and thermal limits of its polymeric insulating layers. Suzhou Daiming utilizes continuous horizontal and vertical drawing-enameling technology to apply precise, multi-layered films. Different base cores require specific polymer formulas:
While enameled magnet wires serve as active conductors for electromagnetic induction, coated GI binding wires are crucial for mechanical stability. During high-speed motor operation, centrifugal forces can cause winding movement. Coated GI binding wire firmly bundles the coil heads and core laminations. Its zinc-plated base prevents rust, while the outer enamel coat prevents short circuits between active coils and structural steel frames.
