Enameled wire is a type of electromagnetic wire, usually refers to the insulation wire used to make coil or winding in electrical products. It is also called the winding wire.
The electromagnetic wire must meet the requirements of various applications and manufacturing processes. The former includes its shape, specification, working at high temperature in short and long time, as well as the strong vibration and centrifugal force under high speed on certain occasions, resistance to corona and breakdown under high voltage, and chemical corrosion resistance in special atmospheres, and the requirements for tensile, bending and wear, as well as the requirements of drawing, bending and wear during winding and inlaying. Swelling and erosion during immersion and drying.

The enamel wire is a wire having an insulating layer, which is a transformation of electromagnetic energy in a winding form, also known as a winding wire.

1. Cutting
The enameled wire is composed of a conductor and an insulator, and the hardness of the two parts is very soft, so it can be cut by using a TabCUT-200 precision cutting machine with a general SiC cutting chip. Since the insulator is coated on the conductor, and its hardness and ductility are quite different, and the insulating layer has a certain degree of peeling, it is better to use some soft materials such as tin foil, rubber, etc. to wrap the cutting part when cutting. Up to prevent the insulation layer at the fracture from peeling off after cutting.

Copper-clad aluminum wire refers to a wire with aluminum core wire as the main body and a certain proportion of copper layer plated on the outside. It can be used as a conductor for coaxial cables and wire and cable conductors in electrical equipment. The aluminum wire has a small specific gravity, but its welding performance is not good. Therefore, the copper-clad aluminum wire is wrapped with a copper layer on the aluminum wire. This copper-clad aluminum wire can not only take advantage of the small aluminum specific gravity, but also improve the welding performance.

1. Conductor resistance ¡ª The resistance of a conductor is proportional to its length and inversely proportional to its cross-sectional area.
2. Conductivity¡ªBased on the resistance 1/58ohm (0.017241 ohm) of a standard soft copper wire with a length of 1m and a cross-sectional area of 1mm2 at 20¡æ, it is called 100% conductivity. The greater the resistance, the lower the conductivity, and the two are inversely proportional.
3. Bending resistance¡ªfix one end of the single wire, add weight to the other end to make it vertically downward, and then bend it back and forth 180 times until the wire breaks. The more bending times, the stronger the bending resistance.
4. Tensile breaking force¡ªthe maximum load weight or force applied to the specimen to break it during a tensile test.
5. Tensile strength¡ªthe breaking force per unit area to bear when the sample is broken during the tensile test.
6. Elongation ¡ª the ratio of the length of the sample after being stretched until it breaks to the original length at the specified standard distance. Conductors have different impedances at different temperatures.
Generally, 20¡ãC or 25¡ãC is the standard. The higher the temperature, the greater the impedance.
