High Mechanical Strength Enameled Flat Copper/Aluminum Wire from China Suppliers and Factory for Vibrating Equipment
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
Q1 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-grade aluminum rod (compliant with GB5584.3-2009). Both are processed through precision drawing and extrusion to maximize mechanical stability.
Q2 Which insulation type is best suited for vibration-prone environments?
QZ (Polyester, 130℃) is highly recommended for vibration environments due to its high mechanical strength and scratch resistance. For more demanding applications requiring superior shock resistance, QZG (Modified Polyester, 155℃) is the preferred choice.
Q3 What are the available conductor dimensions and mechanical strength grades?
Conductor thickness ranges from 0.80 mm to 5.60 mm, and conductor width ranges from 2.00 mm to 16.00 mm with a width ratio of up to 20:1. Three mechanical strength grades are available: C1 (100–180 N/mm²), C2 (180–220 N/mm²), and C3 (220–260 N/mm²). Custom specifications can also be arranged.
Q4 What international quality certifications does the product hold?
All enameled flat wire products are manufactured under ISO9001:2015 quality management and have passed SGS, UL, and CE certifications. Mechanical durability is tested in accordance with GB/T 4074 and IEC 60851 international standards.
Q5 What are typical application areas for this enameled flat wire?
This wire is widely used in windings of electrical equipment exposed to vibration or mechanical stress, including automotive transformers, industrial pumps, heavy machinery reactors, and other electromechanical devices requiring reliable insulation under dynamic load conditions.
Q6 Is it possible to order custom mechanical strength specifications or insulation thicknesses?
Yes. Hengte Electric supports custom orders for specific mechanical strength grades (C1, C2, C3) as well as insulation thickness options (thin film 0.06–0.11 mm or thick film 0.12–0.17 mm). Please contact us with your technical requirements for a tailored solution.
