High Mechanical Strength Enameled Flat Copper/Aluminum Wire - China Suppliers & Factory for Durable Electrical Solutions
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 makes this enameled flat wire suitable for vibration-prone environments?
The wire is manufactured from high-strength oxygen-free copper or electrical aluminum rod using precision drawing and extrusion processes. This enhances mechanical stability, and the insulation grades — particularly QZ and QZG — offer superior scratch and shock resistance, making the wire reliable in applications exposed to continuous vibration or mechanical stress.
Q
What temperature ratings are available for the insulation types?
Six insulation grades are available: QQ/QQN at 120℃, QZ at 130℃, QZG at 155℃, QZY at 180℃, Q(ZY/XY) at 200℃, and QXY at 220℃. Each grade is suited to different thermal and mechanical demands.
Q
What conductor dimensions and strength grades are offered?
Conductor thickness ranges from 0.80 to 5.60 mm and width from 2.00 to 16.00 mm, with a width ratio up to 20:1. Three mechanical strength grades are available — C1, C2, and C3 — covering yield strengths from 100 to 260 N/mm², allowing selection based on specific load requirements.
Q
Which international quality and safety certifications does the product hold?
The products are manufactured under an ISO9001:2015 certified quality management system and have passed SGS, UL, and CE certifications. Mechanical performance testing is conducted in accordance with GB/T 4074 and IEC 60851 standards.
Q
What are the typical applications for this enameled flat wire?
This wire is commonly used in windings of electrical equipment that experience vibration or mechanical stress, including automotive transformers, industrial pumps, and heavy machinery reactors. Its combination of mechanical strength and thermal stability makes it well suited for demanding industrial environments.
Q
Can custom specifications or mechanical strength requirements be accommodated?
Yes. Hengte Electric supports custom mechanical strength requirements and dimensional specifications. Customers can specify conductor size, insulation grade, and strength class to match their exact application needs.
