Glass-Fiber Round Copper Wire is a type of insulated copper wire that uses glass fiber as its outer insulation layer. Unlike conventional wires that use plastic or rubber insulation, this wire is designed to withstand extreme heat and mechanical stress.
 
At its core, the wire contains round copper conductors—usually oxygen-free copper (OFC) or electrolytic tough pitch (ETP) copper—covered with high-temperature-resistant enamel and then wrapped with a layer of woven glass fiber insulation.
 
This structure allows it to operate in environments with temperatures up to 180°C, making it ideal for industrial, automotive, and aerospace applications.
 
Features
The 1mm version of this wire offers a balance of current-carrying capacity, flexibility, and durability, making it suitable for a wide range of applications.
 
Key Features:
Diameter: 1mm – suitable for medium power applications and compact installations.
Temperature Resistance: Rated for continuous operation at 180°C, with short-term tolerance even higher.
Insulation: Dual layer – thermosetting enamel and glass fiber braiding, providing double protection.
Electrical Conductivity: Excellent due to high-purity copper core.
Mechanical Strength: Resistant to abrasion, vibration, and bending fatigue.
Flame Resistance: Glass fiber does not melt or emit toxic gases, making it safer in high-risk environments.

Common Applications Include:
Electric Motors & Transformers: Operates reliably in hot coils and windings.
Aerospace & Aviation: Withstands extreme conditions in aircraft systems.
Electric Vehicles (EVs): Ideal for battery packs, inverters, and heat-prone zones.
Industrial Heating Equipment: Ensures safe and stable current flow near high-temperature components.
Medical Devices & Robotics: Provides precision and reliability in compact, high-performance machines.
 
Conclusion
The 1mm 180℃ Glass-Fiber Round Copper Wire is more than just a conductor—it's a high-performance solution for the challenges of modern electrical and electronic systems. Its ability to operate in harsh temperatures while maintaining electrical integrity and mechanical durability makes it an essential component across industries.
 
As technology evolves and thermal demands increase, this type of wire will continue to play a critical role in powering the future safely and efficiently.
