High Mechanical Strength Enameled Flat Copper/Aluminum Wire from China Suppliers - Durable Factory Products
Product Information
Engineered for durability in vibration-prone environments, this enameled flat wire is made of high-strength oxygen-free copper or electrical aluminum rod, processed through precision drawing and extrusion to enhance mechanical stability. It is widely used in windings of electrical equipment subject to vibration or mechanical stress, such as automotive transformers, industrial pumps, and heavy machinery reactors. Based on insulating paint types, it is divided into six categories with outstanding mechanical performance:
- QQ/QQN (120℃): Polyvinyl Acetal/Self-adhesive – good scratch resistance and flexibility
- QZ (130℃): Polyester – high mechanical strength and scratch resistance (ideal for vibration environments)
- QZG (155℃): Modified Polyester – excellent shock resistance and mechanical strength
- QZY (180℃): Polyester Imide – robust mechanical performance and heat shock resistance
- Q(ZY/XY) (200℃): Composite Layer – balanced mechanical and chemical resistance
- QXY (220℃): Polyamide Imide – reliable mechanical stability in high-temperature conditions

Frequently Asked Questions
What types of insulation coatings are available for the 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) (Composite Layer, 200℃), and QXY (Polyamide Imide, 220℃), each suited to different temperature and mechanical requirements.
What conductor materials are used, and what standards do they meet?
The wire is manufactured using high-strength oxygen-free copper compliant with GB5584.2-2009, or electrical-grade aluminum meeting GB5584.3-2009. Both materials are processed through precision drawing and extrusion to ensure consistent mechanical performance.
What are the available conductor size ranges?
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. Both thin film (0.06–0.11 mm) and thick film (0.12–0.17 mm) insulation options are offered.
Which industries and applications is this enameled flat wire suitable for?
This wire is specifically engineered for vibration-prone and mechanically demanding applications, including windings in automotive transformers, industrial pumps, heavy machinery reactors, and other electrical equipment subject to mechanical stress or frequent vibration.
