Early use of cotton yarn and silk, known as yarn wrapped wire and wire wrapped wire, was used in motors and electrical appliances. Due to the large thickness of the insulation and low heat resistance, most have been replaced by enameled wires. It is currently only used as a high frequency winding wire. In the large and medium-sized winding wires, when the heat resistance level is high and the mechanical strength is large, the glass fiber covered wire is also used, and the appropriate adhesive paint is used in the manufacture.

In the enameled wire, the paper covered wire still occupies a considerable position, mainly used in oil-immersed transformers. The oil-paper insulation formed at this time has excellent dielectric properties, is inexpensive, and has a long life. The paper covered wire is a wire which is annealed or drawn after being pressed or drawn by an oxygen-free copper rod or an electric round aluminum rod, and then wrapped on a copper (aluminum) conductor to wrap two or more layers of insulating paper (including Winding wire for telephone paper, cable paper, high-voltage cable paper, inter-turn insulating paper, etc., suitable for oil-immersed transformer coils and other similar electrical windings. The bare copper (aluminum) wire produced by the extrusion process is the most ideal material for producing cable paper covered wires.

In recent years, the film enameled wire has been developed more rapidly, mainly including polyester film and polyimide film wrapping wire. Recently, there are also mica-coated polyesterimide film wrapped copper flat wires for wind power generation. When the heat resistance level is required to exceed the limit of the organic material, it is usually coated with an inorganic insulating varnish. The existing inorganic enameled wire can be further classified into glass film wires, oxide film wires, and ceramic wires.

In terms of the Enameled Aluminum Wire itself, the resistivity is different from that of copper. Therefore, if the copper is changed to the enameled wire, as long as the wire diameter of the aluminum wire is increased according to the resistivity ratio, the aluminum wire will not increase in temperature, current, and energy efficiency. It is worse than the copper wire. Therefore, in terms of design, there is no problem in converting copper into aluminum. However, due to the extremely live wave of aluminum metal, it is easy to oxidize, and it is difficult to apply tin. Many companies are very troubled by this problem. Therefore, the key to the application of enameled aluminum wire is how to solve the welding problem of the connection point.

As for aluminum wire welding, there are terminal riveting and solder wire welding, and some copper wires are used to wrap the aluminum wire and re-weld. At present, there are not many companies that handle aluminum arc welding in China. The welding of aluminum wire is divided into two processes: one is stripping, and the other is welding.

In paint stripping, there are many factories that use high-temperature tin soldering. After the iron is hot, the aluminum wire turns yellow and black. It is basically impossible to solder. In some paint stripping machines, the temperature is very high due to friction. Therefore, the aluminum after paint stripping On the one hand, the wire is damaged, and on the other hand, the surface of the aluminum wire becomes black and the oxidation is severe. It is also extremely difficult to apply tin.

Firstly, the terminals are riveted, and the aluminum wire oxidizes quickly. In addition, the potential difference between copper and aluminum is large. Electrochemical corrosion will gradually occur during the power-on process. The resistance of the connection point will gradually increase and the temperature rise will become higher. Finally, the power must not be applied.

Solder wire welding is also very problematic, the temperature of the soldering iron can not be very large, so it is very easy to produce sound welding surfacing, the surface looks very full, in fact, it is wrapped inside, and other flux can not be vaporized for a short time , so there will be a lot of carbon flux residue inside the solder joints, this way is not reliable by the argument.

The common method of aluminum enameled wire bonding is to use a special flux-cored solder wire (sold by Shanghai Jifeng Electromechanical) to solder with electric soldering iron. Generally, aluminum enamel wire and aluminum enamel wire/bare aluminum wire/aluminum alloy/copper wire with small wire diameter. The welding method is suitable for selecting this welding method (wires, rows and foils with large wire diameter or large area can be flame brazed, see copper-aluminum welding). The welding method of the workpiece is better, the quality is reliable and the operation is convenient. .

Welding instructions: When soldering, the soldering iron tip should be as close as possible to the soldered body, and then the soldering wire should be sent to the soldering iron tip to melt the soldering wire and complete the soldering. (This method can make the flux in the soldering wire fully contact with the board surface to achieve the best. Welding effect); For the welding of enamelled aluminum wire and copper wire (or aluminum wire), the two wires are usually twisted and twisted after scraping, and the twisting size directly affects the welding effect, and the twist (ie, the curvature) The larger the amount of tin is, the stronger the welding between the two wires is.

For the newly welded enameled wire, do not use the hand to pull it too eagerly, wait for it to completely cool, and then verify its reliability; Unused solder wire, use a lighter to burn the wire head into a ball shape, so as to avoid the loss of liquid flux in the wire, affecting the next welding.

In the industrial production process, welding is a relatively important technology. In the face of production, the understanding of welding plays a crucial role, but when welding, there should be attention when it should be noted. Edit the precautions for dip soldering of Enameled Aluminum Wire.

Precautions for dip soldering of aluminum enameled wire:

1. Because the melting point of aluminum is relatively low, it is easy to melt into the tin pot. Therefore, when welding a small diameter aluminum enamel wire (below 0.4mm), the temperature should be controlled within 300 °C, so that the melting speed of the aluminum wire is reduced, and avoiding The aluminum wire is embrittled and should not be soldered with high temperature tin.

2, Aluminum enameled wire must be stripped paint, stripping can be used mechanical (scraping paint, paint stripping machine) and chemical (paint stripping powder, stripping water) two stripping methods, Xiaobian recommended the use of chemical stripping, using chemical methods After stripping, the solder joint should be fully rinsed; try not to use mechanical methods to remove the paint, which will easily scratch the aluminum wire and produce burrs, thus reducing its toughness.

3, Because of the instability of aluminum, so you need to paint immediately, welding immediately, do not let the aluminum enamel wire end of the stripping paint contact with the air for a long time, to avoid excessive oxidation, usually it is necessary to weld within 5 hours after stripping If there is no welding, it needs to be cut off and stripped again.

4. At the same time, the stripping length can be customized according to the length of the welding, that is, how long the soldering is to go to the paint, to avoid exposing the aluminum to the air, leaving hidden dangers to the solder joint.

5, In addition, in the dip soldering, need to gently shake 2 to 3 times in the tin pot to avoid air bubbles.

6. The connection of the aluminum enamel wire and the lead wire requires that the aluminum wire be wound around the copper wire with a small arc, which can reduce the occurrence of the false welding phenomenon and improve the welding strength.

The Enamelled Wire refers to a metal wire used for winding an electromagnetic coil with an insulating varnish as an insulating coating, also called a magnet wire. Enameled wire is the main and key raw material for electromagnetic winding of electric motors, electrical appliances and household appliances, telecommunications and electronic instruments. After the entry of WTO, with the rapid development of industrial electrical appliances, household appliances, telecommunications, electronic products, etc., it has brought a wide range of enameled wires. Application areas and markets. China has become the world's enameled wire manufacturing center and processing base. It is the world's largest producer and seller of enameled wire, accounting for about 30% of global production. The production of enameled wire in China has increased by more than 10% per year for nearly two decades. It is expected to increase to around 50% by 2015, reaching a scale of 1.6 million t/a, making it a veritable enameled wire production country and a strong country.

After long-term development, China has become the largest producer and user of electronic components such as relays, micro-motors and electronic transformers. However, due to the gap between technology, technology and equipment and the international market, the production capacity of fine enameled wire is far from domestic. Meet the needs. Only about 30% of China's fine enameled wire is used by domestic manufacturers, and the remaining 70% is imported.

The future growth of demand for local micro-electromagnetic enameled wire in China comes from the natural growth of market demand, and the other part comes from import substitution, especially in the field of import substitution. According to the investigation and analysis of the wire and cable branch winding wire special committee of China Electrical Equipment Industry Association, it has become a veritable enameled wire production country and a strong country.
