What details should be paid attention to when making enameled wire?

British Standard Wire Gauge (often abbreviated to Standard Wire Gauge or SWG) is a unit for denoting wire size given by BS 3737:1964 (now withdrawn). It is also known as the Imperial Wire Gauge or British Standard Gauge. Use of SWG sizes has fallen greatly in popularity, but they are still used as a measure of thickness in guitar strings and some electrical wire. Cross sectional area in square millimetres is now the more usual size measurement for wires used in electrical installation cables. The current British Standard for metallic materials such as wire and sheet is BS 6722:1986, which is a solely metric standard.

Glass-fiber covered aluminum magnet wire used to have weak coating strength (abrasion resistance, shock resistance, and flexibility). However, that disadvantage has been significantly improved recently by refining material selection and manufacturing methods. The demand for glass-fiber covered aluminum magnet wire is increasing as the wires have excellent uniformity and electrical properties under high temperatures and humidity.

Painted wire (electromagnetic wire) is the base and key material of the motor, electrical, household appliance, electronics, instrumentation, electromagnetic windings. With the rapid development of my country’s home appliance industry, electronic information, automobile and other industries, the scale of electromagnetic wire production enterprises expanded, and the country has developed from thousands of tons to the 10,000-tonnes. The rapid development of industrial appliances, household appliances, automotive and other industries, bringing electromagnetic wires and markets, but at the same time, rapid advancement of technology has made a growing demand for electromagnetic wires.

The space factors of magnet wires are compared in the right figure. The space factors of enamelled wires are superior to those of other wires for winding, as are their electrical properties. However, more careful examination must be made of the following properties as compared with other wires.

Paper covered wire by Electrical Aluminium Pole extrusion die by a certain size or drawn wire after annealing, and then in the aluminum conductor wrapped more than two or two insulating paper (including paper, telephone, cable paper, high voltage cable paper, turn insulation paper) of the winding wire, suitable for oil-immersed transformers and other electrical winding with a similar wire. Produced by the extrusion process electrical bare aluminum wire is wrapped production of the cable wire is the best material.

Good Quality Paper Covered Flat Aluminum Enameled Copper Wire is made of bare copper wire or bare aluminum wire, or paper-covered wire as the core, wrapped with paper for insulation. According to customer and national standards, the conductor is wrapped with telephone paper, electromagnetic paper, and high-density inter-turn insulation paper. As conductor insulation, it is an ideal material for civilian-made oil-immersed transformers; especially semi-hard insulated copper wires, which can significantly improve the winding resistance. The mechanical properties and short-circuit resistance can be widely used in the winding of large and medium-sized transformers.

Speaking of the copper enameled wire, I believe everyone should know. Today, we introduce you to a wire, ie the copper paint package. Let us simply look at the transportation and preservation of copper-clad aluminum wires, because if many wires are transported incorrect, it is very likely to be used, so let us simply understand the transportation and preservation of the copper paint wire, so you can be here.

Magnet Wire: enameled wire, winding wire, enamelled wire, magnetic wire, conductor covered

There are some differences between polyester enameled wire and polyurethane enameled wire in terms of use occasions and performance:
Polyester enameled wire, composed of copper conductor and polyester resin, has a thermal class of 130, and after modification, the thermal class of the enameled wire is 155. It has good mechanical strength, paint film adhesion, excellent electrical, scratch resistance, chemical resistance, thermal stability and solvent resistance. It is widely used in various motors, electrical appliances, meters, telecommunications equipment and home appliances; the weakness of this product is poor thermal shock resistance and low moisture resistance.

Polyurethane enameled wire, thermal grade is 130,155,180. The biggest feature is that it has direct solderability, good high frequency resistance, easy coloring, and good moisture resistance. It is widely used in electronic appliances, precision instruments, telecommunications, and meters. The weakness of this product is that the mechanical strength is slightly poor, and the heat resistance is not high. , And the flexibility and adhesion of the production of large-size wires are poor, so the specifications of the product are mostly small and medium-sized wires.

The selection criterion of the electromagnetic wire is not considered for resistance, as the problem of resistance and fever can be done by selecting the same cross-sectional wire, it is the main consideration of the thick wire or the thin wire is mainly considered Operability.

Enameled wire motors, electrical appliances, home appliances, communications, electronic information, instrumentation, power tools, automobiles and other industries provide supporting basic material industries. They are the main and key raw materials for electromagnetic windings of motors and electronic instruments. The rapid development of electronic products, etc., has brought a broader application field and market to enameled wires, but at the same time, higher requirements have been put forward for enameled wires, and enameled wires have continued to develop towards a high level and high quality.

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.

Aluminum bare magnet wire (Anodized Bare Aluminium wire) belongs to the special electromagnetic wire and the insulation layer is the aluminum oxide .Because of no thermal aging phenomenon, it can be used as insulation level of class 220.
The insulation layer of such product is thin, high temperature resistance and insulation performance stability,which is the best choice for low voltage winding wires with producing high temperature, poor environment, heat dissipation difficulty and so on. It can widely be used in electromagnetic industries at home and abroad.

After the product is manufactured, whether its appearance, size and performance meet the requirements of the technical standards of the product and the technical agreement of the user must be judged by the inspection beam and measured; the test shall be compared with the technical standard of the product or the technical agreement of the user and meet the requirements If it is qualified, otherwise, it is unqualified. Passing the inspection can reflect the stability of the enameled wire product quality, the material and the rationality of the process. Therefore, the quality inspection has the function of checking, preventing and identifying.
