Enameled magnet wires on the market are usually made of metal aluminum and metal copper. GSAL mainly produces enameled copper wires, such as high temperature resistant enameled copper rectangular wire and high temperature resistant enameled copper round wire. Enameled wire is one of the main types of insulating wire for coils or windings in the manufacture of electrical products. It is composed of conductors and insulating layers. After the bare wires are annealed and softened, they are painted and baked many times. Enameled wire has four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

Workshop & Equipment

GSAL has six production lines in total. There are 2 sets of round wires and 2 set of flat wire respectively. The other 2 sets of wires are for thick copper rods to thinner wires. The production capacity of flat wire and round wire is 800 tons and 1400 tons per month.

The leading products of GSAL are polyesterimide enameled wire, polyesterimide or polyester composite polyamideimide enameled wire and anti-corona enameled wire.

Polyesterimide enameled wire has a high temperature resistance grade of 180, a heat shock resistance temperature of 200°C, good heat shock resistance, high softening and breakdown temperature resistance, excellent mechanical strength, good solvent resistance and refrigerant resistance. However, It is easy to hydrolyze under closed conditions.

Polyesterimide or polyester composite polyamideimide enameled wire, temperature resistance grade 200, heat shock resistance temperature 220°C, this product has high heat resistance, and also has freezing resistance.

Anti-corona enameled wire, temperature resistance grade 200, heat shock temperature resistance 220°C, softening and breakdown resistance greater than or equal to 320°C, pulse rise time 100ns, enameled wire life not less than 12 hours, this product is used in high frequency motors to prevent the corona generated on the surface of the conductor from damaging the insulation layer under high-frequency conditions insulation properties.
