Self-Adhesive Enameled Flat Copper/Aluminum Wire from China Suppliers - Quality Wire from Leading Factory
Product Information
Equipped with a reliable self-adhesive layer, this enameled flat wire is fabricated from high-quality oxygen-free copper or electrical aluminum rod, processed through drawing, extrusion, and special adhesive coating. It is designed for windings that require stable fixation without additional adhesives, such as high-density transformers, precision reactors, and electronic coils. Based on insulating paint and self-adhesive properties, it covers six core categories, including specialized self-adhesive variants:
- QQ/QQN (120℃): Polyvinyl Acetal/Self-adhesive Polyvinyl Acetal – core self-adhesive type with reinforced adhesion via heating
- QZ (130℃): Polyester – non-self-adhesive base type (optional self-adhesive coating)
- QZG (155℃): Modified Polyester – non-self-adhesive (custom self-adhesive available)
- QZY (180℃): Polyester Imide – non-self-adhesive (custom self-adhesive available)
- Q(ZY/XY) (200℃): Composite Layer – non-self-adhesive (custom self-adhesive available)
- QXY (220℃): Polyamide Imide – non-self-adhesive (custom self-adhesive available)

Self-Adhesive & Performance Advantages
- Self-adhesive layer (QQ/QQN) forms strong bonds when heated, simplifying winding assembly and reducing production time.
- Conductors (copper/aluminum) comply with GB5584 series standards, ensuring excellent conductivity and mechanical stability.
- Insulation layers retain their original properties (e.g., heat resistance, solvent resistance) while adding adhesion functionality.
- Breakdown voltage meets Grade 1 (1000V) and Grade 2 (2000V) standards, ensuring electrical safety after adhesion.
Hengte Electric is a professional manufacturer of self-adhesive enameled wires, holding ISO9001:2015 certification. Products have passed SGS, UL, and CE tests, with self-adhesive performance validated by strict adhesion tests. We offer both standard self-adhesive QQ/QQN and custom self-adhesive coatings for other insulation categories to meet specific winding requirements.
