I Would Like To Introduce Copper Magnet Wire To You

  • Magnet wire is usually divided into enameled wire, winding wire, enameled winding wire and inorganic insulated wire. Magnet wire includes copper magnet wire and aluminum magnet wire.

    Magnet wire is an insulated wire used to make coils or windings in electrical products. Also called winding wire. Magnet wires must meet the requirements of a variety of uses and manufacturing processes. The former includes its shape, specifications, ability to work at high temperatures for short and long periods of time, as well as withstanding strong vibration and centrifugal force at high speeds in some occasions, resistance to corona and breakdown under high voltage, and resistance to chemicals in special atmospheres Corrosion, etc.; the latter includes requirements for stretching, bending and abrasion during winding and embedding, as well as swelling and erosion during dipping and drying.

    The earliest enameled wire was oily enameled wire, made of tung oil. The paint film has poor abrasion resistance and cannot be directly used to make motor coils and windings. It needs to be covered with cotton yarn when used. Later, polyvinyl formal enameled wire came out, and its mechanical properties were greatly improved. It can be directly used in motor windings and is called high-strength enameled wire.

    With the development of weak current technology, there has been a self-adhesive enameled wire, which can obtain a coil with better integrity without dipping and baking. But its mechanical strength is poor, and it can only be used in micro motors and small motors. In addition, in order to avoid the trouble of first removing the paint film during soldering, direct solder enameled wire has been developed. The paint film can fall off by itself in the high-temperature tin bath, making the copper wire easy to solder.

    Later, according to the place of application, round enameled wire and rectangular enameled wire were produced, which made the use of small and more efficient.
