China Suppliers Factory Enameled Flat Wire - Solvent & Corrosion Resistant for Harsh Environments
Designed to withstand harsh chemical environments, this enameled flat wire is fabricated from high-quality oxygen-free copper or electrical aluminum rod, processed through precision drawing and extrusion. It is specially suited for windings in electrical equipment operating in solvent-exposed or corrosive conditions, such as chemical industry reactors, marine electrical devices, and oilfield equipment. Based on insulating paint properties, it is classified into six categories with strong solvent and corrosion resistance:
- ●QQ/QQN (120℃): Polyvinyl Acetal/Self-adhesive Polyvinyl Acetal – good hydrolysis and transformer oil resistance
- ●QZ (130℃): Polyester – basic solvent resistance for general corrosive environments
- ●QZG (155℃): Modified Polyester – enhanced solvent and shock resistance
- ●QZY (180℃): Polyester Imide – excellent chemical solvent and heat shock resistance
- ●Q(ZY/XY) (200℃): Polyester Imide/Polyamide-Imide Composite – superior refrigerant, solvent, and radiation resistance
- ●QXY (220℃): Polyamide Imide – top-tier chemical solvent resistance
| Conductor Thickness (a) | 0.80 – 5.60 mm |
| Conductor Width (b) | 2.00 – 16.00 mm |
| Conductor Width Ratio | 20:1 |
| Insulation Thickness | Thin film: 0.06 – 0.11 mm | Thick film: 0.12 – 0.17 mm |

Frequently Asked Questions
Q What types of insulation coatings are available for this enameled flat wire?
The enameled flat wire is available in six insulation categories: QQ/QQN (Polyvinyl Acetal, 120℃), QZ (Polyester, 130℃), QZG (Modified Polyester, 155℃), QZY (Polyester Imide, 180℃), Q(ZY/XY) (Polyester Imide/Polyamide-Imide Composite, 200℃), and QXY (Polyamide Imide, 220℃). Each grade offers different levels of thermal and chemical resistance to suit specific application environments.
Q What are the standard conductor dimensions for this flat wire?
The conductor thickness (a) ranges from 0.80 mm to 5.60 mm, and the conductor width (b) ranges from 2.00 mm to 16.00 mm, with a maximum width-to-thickness ratio of 20:1. Insulation thickness options include thin film (0.06–0.11 mm) and thick film (0.12–0.17 mm). Custom dimensions are also available upon request.
Q Which international standards does the product comply with?
The conductors comply with GB5584 series standards, while the insulation layers are tested according to GB/T 4074 and IEC 60851 standards. The product has also passed SGS, UL, and CE certification tests, ensuring reliability for both domestic and international markets.
Q What is the breakdown voltage rating of the insulation?
At room temperature, the insulation achieves a breakdown voltage of 1000V for Grade 1 and 2000V for Grade 2, as tested under GB/T 4074 and IEC 60851 standards. These values ensure reliable electrical insulation in demanding operating environments.
