    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
    QWhat is the difference between QQ/QQN self-adhesive enameled flat wire and other insulation types?
    QQ/QQN types are the core self-adhesive categories based on Polyvinyl Acetal insulation. They form strong bonds when heated, eliminating the need for external adhesives during winding assembly. Other insulation types (QZ, QZG, QZY, Q(ZY/XY), QXY) are non-self-adhesive by default but can be customized with a self-adhesive coating upon request.
    QWhat conductor materials are available for self-adhesive enameled flat wire?
    The wire is available in two conductor materials: high-quality oxygen-free copper and electrical aluminum rod. Both comply with GB5584 series standards, ensuring excellent electrical conductivity and mechanical stability for demanding winding applications.
    QWhat temperature ratings are available for different insulation types?
    Temperature ratings range from 120℃ to 220℃ across the six categories: QQ/QQN (120℃), QZ (130℃), QZG (155℃), QZY (180℃), Q(ZY/XY) (200℃), and QXY (220℃). This wide range allows customers to select the most suitable grade for their specific thermal environment.
    QWhat are the available size ranges for conductor thickness and width?
    Conductor thickness (a) ranges from 0.80 mm to 5.60 mm, and conductor width (b) ranges from 2.00 mm to 16.00 mm, with a conductor width ratio of up to 20:1. Insulation thickness is available in thin film (0.06–0.11 mm) and thick film (0.12–0.17 mm) options.
    QWhat certifications does this self-adhesive enameled flat wire hold?
    Hengte Electric holds ISO9001:2015 quality management certification. The self-adhesive enameled flat wire products have passed SGS, UL, and CE testing, with self-adhesive performance validated through rigorous adhesion tests. Breakdown voltage meets Grade 1 (1000V) and Grade 2 (2000V) standards.
    QWhat applications are self-adhesive enameled flat wires typically used for?
    Self-adhesive enameled flat wires are primarily used in windings that require stable fixation without external adhesives. Typical applications include high-density transformers, precision reactors, and electronic coils where secure winding, space efficiency, and consistent electrical performance are critical requirements.
