High Mechanical Strength Enameled Flat Copper/Aluminum Wire - China Suppliers & Factory Quality 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
Q
What types of insulation grades are available for this enameled flat wire?
Six insulation grades are available: QQ/QQN (120℃, Polyvinyl Acetal/Self-adhesive), QZ (130℃, Polyester), QZG (155℃, Modified Polyester), QZY (180℃, Polyester Imide), Q(ZY/XY) (200℃, Composite Layer), and QXY (220℃, Polyamide Imide). Each grade is optimized for different temperature and mechanical performance requirements.
Q
What conductor materials are used, and what standards do they comply with?
The wire is available in two conductor materials: high-strength oxygen-free copper complying with GB5584.2-2009, and electrical aluminum complying with GB5584.3-2009. Copper offers high tensile strength and ductility, while aluminum provides a lightweight alternative with balanced mechanical performance.
Q
What are the available conductor dimensions and mechanical strength grades?
Conductor thickness (a) ranges from 0.80 to 5.60 mm, and conductor width (b) from 2.00 to 16.00 mm, with a maximum width ratio of 20:1. Three mechanical strength grades are offered — C1 (Rp0.2 > 100–180 N/mm²), C2 (Rp0.2 > 180–220 N/mm²), and C3 (Rp0.2 > 220–260 N/mm²) — to suit different application demands.
Q
Which applications is this enameled flat wire most suitable for?
This enameled flat wire is specifically engineered for vibration-prone and mechanically demanding environments. Typical applications include automotive transformers, industrial pumps, heavy machinery reactors, and windings of electrical equipment subject to continuous mechanical stress or vibration.
