Class 155 polyester glass fiber coated insulated round copper magnet wire, a composite material composed of polyester resin and glass fiber, used to wrap the copper conductor of the magnet wire and the copper conductor of the magnet wire is tightly wrapped by the insulating material, which can ensure the stability and safety of the current during transmission. It is widely used in electrical components such as transformers, motors, inductors, etc.
