High Mechanical Strength Enameled Flat Copper/Aluminum Wire from China Suppliers - Durable Factory Direct 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 conductor materials are available for this enameled flat wire?
The enameled flat wire is available in two conductor materials: high-strength oxygen-free copper (compliant with GB5584.2-2009) and electrical aluminum rod (compliant with GB5584.3-2009). Both materials undergo precision drawing and extrusion to enhance mechanical stability.
Q Which insulation type is best suited for vibration-intensive environments?
The QZ (Polyester, 130℃) grade is specifically highlighted for vibration environments due to its high mechanical strength and scratch resistance. For higher thermal demands with shock resistance, QZG (Modified Polyester, 155℃) is also an excellent choice.
Q 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 conductor width ratio of 20:1. Custom dimensions can be arranged based on specific application requirements.
Q What quality certifications does this product hold?
Hengte Electric is an ISO9001:2015 certified supplier. The enameled flat wire products have passed SGS, UL, and CE certifications, and meet GB/T 4074 and IEC 60851 mechanical durability test standards, ensuring reliable performance in demanding mechanical environments.
Q What mechanical strength grades are offered?
Three mechanical strength grades are available: C1 (Rp0.2 > 100–180 N/mm²), C2 (Rp0.2 > 180–220 N/mm²), and C3 (Rp0.2 > 220–260 N/mm²). Customers can select the grade that best matches their application's mechanical load requirements.
Q What are the typical applications for this enameled flat wire?
This enameled flat wire is widely used in windings of electrical equipment exposed to vibration or mechanical stress, including automotive transformers, industrial pumps, and heavy machinery reactors. Its high mechanical durability makes it suitable for both standard and harsh operating conditions.
