Enameled flat wire is manufactured using oxygen-free copper or electrical aluminum rods, which are drawn or extruded through specification molds. This product is primarily utilized in the windings of electrical equipment such as transformers and reactors. Based on the type of insulating paint applied, it is categorized into six main classes: 120 polyvinyl acetal/self-adhesive polyvinyl acetal enameled copper (aluminum) flat wires (QQ/QQN), 130 polyester enameled flat wires (QZ), 155 modified polyester enameled flat wires (QZG), 180 polyester imide enameled copper (aluminum) flat wires (QZY), 200 polyester imide/polyamide-imide composite enameled copper (aluminum) flat wires (Q(ZY/XY)), and 220 polyamide imide enameled copper (aluminum) wires (QXY).
The conductor material for soft copper flat wire adheres to GB5584.2-2009 standards, with a resistivity of ≤0.017241 Ω·mm²/m at 20°C, accommodating varying mechanical strength requirements. Similarly, soft aluminum flat wire complies with GB5584.3-2009, featuring a resistivity of ≤0.02801 Ω·mm²/m at 20°C. Insulation options include thin film ranging from 0.06 to 0.11 mm or thick film from 0.12 to 0.17 mm, depending on specific needs. For hot adhesive enameled flat wire, the self-adhesive layer typically measures between 0.03 and 0.06 mm in thickness, monitored using a dielectric loss meter for precision.
Production scope covers conductor thickness (a) from 0.80 to 5.60 mm and conductor width (b) from 2.00 to 16.00 mm, with a conductor width ratio of up to 20:1. Technical parameters vary by enameled wire category, each with distinct thermal levels, performances, and standards. For instance, polyvinyl acetal/self-adhesive acetal wires (QQ/QQN) offer excellent resistance to transformer oil, scratch resistance, flexibility, adhesion, and hydrolysis resistance, conforming to GB/T 7095.2-2008 and IEC 60317-18:2004. Other categories like polyester (QZ), modified polyester (QZ(G)), polyester imide (QZY), polyester imide/polyamide-imide composite (Q(ZY/XY)), and polyamide imide (QXY) provide high mechanical strength, good electrical performance, solvent resistance, and heat resistance, adhering to relevant GB and IEC standards.
Model names and production specifications include QQB120 for acetal/self-adhesive acetal, QZB130 for polyester, QZ(G)B155 for modified polyester, QZYB180 for polyester imide, QYB220 for polyamide imide, and Q(ZY/XY)B200 for composite layers, all with conductor dimensions a: 0.80-5.60 mm and b: 2.00-16.00 mm. Paint film insulation is graded into Grade 1 (0.06≤δ≤0.11 mm) and Grade 2 (0.12≤δ≤0.17 mm), with minimum breakdown voltage values specified for room temperature and high temperature conditions.
