Enameled wire and belongs to a category of electromagnetic wires, and generally refers to insulated wires used to make coils or windings in electrical products. Also called winding wire.
In daily life, copper wire is used as a wire. It has good electrical conductivity and is widely used in the manufacture of wires, cables, brushes, etc.; it has good thermal conductivity, and is often used to manufacture magnetic instruments and meters that must be protected from magnetic interference, such as compasses and aviation instruments. It has excellent plasticity and is easy to heat and press. Cold pressure processing can be made into copper materials such as tubes, rods, wires, strips, strips, plates, and foils. Pure copper products are divided into smelted products and processed products.
enameled wire is a main type of winding wire, which is composed of a conductor and an insulating layer. After the bare wire is softened by annealing, it is painted and baked many times. However, it is not easy to produce products that not only meet the requirements of the standard, but also meet the requirements of customers. It is affected by the quality of raw materials, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various enameled wires are different, but they all have Mechanical properties, chemical properties, electrical properties, and thermal properties are four major properties.
Advantages of copper clad aluminum enameled wire:
DC resistivity: the DC resistivity of copper clad aluminum wire is about 1.5 times that of pure copper wire; when the resistance value is the same, the weight of copper clad aluminum wire is about 1/2 of that of pure copper wire.
Good solderability: copper clad aluminum wire is concentrically coated with a layer of pure copper, so it has the same solderability as pure copper wire, without special treatment like aluminum wire.
Light weight: The density of copper clad aluminum wire is 1/3 of that of pure copper wire of the same wire diameter, which is very useful for reducing the weight of cables and coils.
