Polyimide - fluorine 46 composite film sintered copper flat wire is made of corona-resistant polyimide film coated on both sides with polyperfluoroethylene propylene resin by high-temperature sintering of polyimide - fluorine 46 composite film layer; there are made of oxygen-free copper.

The polyimide-fluoro46 composite film provides additional mechanical strength and a protective layer that effectively supports the copper conductor, reducing the risk of mechanical damage and breakage.
Polyimide – Fluorine 46 composite film sintered copper flat wire has high mechanical strength and electrical properties, can withstand large impact load capacity, high temperature resistance, water resistance, radiation resistance and other characteristics.
This copper flat wire has good flexibility and malleability, making it easy to bend and install. They are also relatively lightweight, helping to reduce overall weight. It can be cut and customized as needed to suit different application scenarios.
It is suitable for medium and high-voltage AC motors, large and medium-sized DC motors, locomotive traction motors, large and medium-sized submersible (oil) electric pumps, rolling steel AC and DC motors, mining traction motors.
