Background

The electric wire refers to a wire for transmitting electric energy. The bare wires, the electromagnetic wires and the insulated wires. The bare wires have no insulating layer and comprise copper, aluminum flat wires, overhead stranded wires and various profiles (such as molded lines, buses, copper bars, aluminum bars and the like). It is mainly used for outdoor overhead and indoor bus bars and switch boxes. Magnet wires are insulated wires that, when energized, produce a magnetic field or induce a current in a magnetic field. It is mainly used for motor and transformer coils and other relevant electromagnetic equipment. The conductor is mainly a copper wire, and has a thin insulating layer, good electrical and mechanical properties, heat resistance, moisture resistance, solvent resistance and the like. Different insulating materials are selected to achieve different characteristics.
