Self-Adhesive Enameled Flat Copper/Aluminum Wire from China Suppliers - High-Quality Factory-Made Solutions
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.
Frequently Asked Questions
What is self-adhesive enameled flat wire and how does it differ from standard enameled wire?
Self-adhesive enameled flat wire features an additional self-adhesive coating applied over the standard insulation layer. When heated, this layer forms a strong bond between adjacent windings, eliminating the need for external adhesives or varnish impregnation. Standard enameled wire lacks this bonding layer and typically requires additional processing steps to fix windings in place.
What conductor materials are available for this self-adhesive enameled flat wire?
The wire is available in two conductor materials: high-quality oxygen-free copper and electrical-grade aluminum rod. Both comply with GB5584 series standards, providing excellent electrical conductivity and mechanical strength. Copper conductors offer superior conductivity, while aluminum conductors are a lighter and more cost-effective alternative.
What temperature ratings are available for the insulation types?
Six insulation categories are available covering a wide temperature range: QQ/QQN at 120℃, QZ (Polyester) at 130℃, QZG (Modified Polyester) at 155℃, QZY (Polyester Imide) at 180℃, Q(ZY/XY) (Composite Layer) at 200℃, and QXY (Polyamide Imide) at 220℃. Custom self-adhesive coatings are available for all categories except QQ/QQN which is the standard self-adhesive type.
What are the main applications for self-adhesive enameled flat wire?
This wire is primarily used in applications that require stable winding fixation without additional adhesives. Typical applications include high-density transformers, precision reactors, electronic coils, inductors, and motor windings where compactness, dimensional stability, and reliable insulation are critical performance requirements.
What certifications and quality standards does the product comply with?
The self-adhesive enameled flat wire is manufactured by Hengte Electric under ISO9001:2015 quality management certification. Products have been tested and certified by SGS, UL, and CE. Breakdown voltage compliance meets Grade 1 (1000V) and Grade 2 (2000V) standards. Conductor materials conform to GB5584 series standards, and self-adhesive performance is validated through strict adhesion testing protocols.
Can custom self-adhesive coatings be applied to high-temperature insulation types such as QZY or QXY?
Yes. While QQ/QQN is the standard self-adhesive type, Hengte Electric offers custom self-adhesive coating solutions for all other insulation categories including QZ, QZG, QZY, Q(ZY/XY), and QXY. This allows customers to benefit from self-bonding functionality across the full temperature range up to 220℃, catering to specialized and high-performance winding requirements.
