Self-Adhesive Enameled Flat Copper/Aluminum Wire from China Suppliers | Quality Factory Manufacturing
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)

❓ Frequently Asked Questions
Q
What is a self-adhesive enameled flat wire and how does it differ from standard enameled wire?
A self-adhesive enameled flat wire is a flat conductor coated with both an insulating paint layer and an additional self-adhesive layer. Unlike standard enameled wire, which requires external adhesives or varnish to fix windings in place, self-adhesive wire bonds automatically when heated, streamlining the assembly process and improving winding stability.
Q
What temperature ratings are available for self-adhesive enameled flat wire?
The product line covers a wide range of temperature ratings: QQ/QQN at 120℃, QZ at 130℃, QZG at 155℃, QZY at 180℃, Q(ZY/XY) at 200℃, and QXY at 220℃. Custom self-adhesive coatings can be applied to most insulation categories based on your specific application requirements.
Q
What conductor materials are used, and what standards do they comply with?
The conductors are made from high-quality oxygen-free copper or electrical-grade aluminum rod. Both materials comply with the GB5584 series standards, which guarantee excellent electrical conductivity and long-term mechanical stability under operating conditions.
Q
What are the available conductor dimensions and insulation thickness options?
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 maximum width-to-thickness ratio of 20:1. Insulation is available in thin film (0.06–0.11 mm) and thick film (0.12–0.17 mm). The self-adhesive layer thickness is 0.03–0.06 mm for QQ/QQN and custom types.
Q
What certifications and quality standards does this product meet?
Hengte Electric holds ISO9001:2015 quality management certification. The self-adhesive enameled flat wire has also passed SGS, UL, and CE testing. Breakdown voltage meets both Grade 1 (1000V) and Grade 2 (2000V) standards, and self-adhesive performance is validated through strict adhesion testing protocols.
Q
What are the typical applications for self-adhesive enameled flat wire?
This wire is widely used in applications where stable winding fixation is critical without the need for external adhesives. Typical use cases include high-density transformers, precision reactors, and various electronic coils. Its flat geometry enables higher fill factors and more compact coil designs compared to round wire alternatives.
