Copper Clad Aluminum Wire is a new enameled wire, is composed of aluminum conductor covered with copper materials, maybe self-bonding, also called self-bonding enameled wire. And the short word is ECCA.

Question: During our production process, we found that one axis of enameled wire is wound around the axial inductance. This axis of enameled wire and other axis of enameled wire are wound on the same magnetic core. The inductance of the enameled wire with this axis is relatively high. We made 1mH inductance, and the enameled wire of the other axis was only 960uH, and the problematic wire of this axis was 1.025mH, and the inductance test frequency was 796kHz. (1) The number of stitches is the same as the number of turns, excluding the slip ring. (2) The 1-meter straight resistance is a bit smaller than that of other shafts. I personally think that the enameled wire contains magnetic substances, but if it contains magnetic substances, the resistivity should be greater, and the DC resistance should be greater. So please help to solve the problem, or have encountered this kind of problem before, please analyze it, thank you in advance!

According to the characteristics and uses of insulation, winding wires can be divided into four categories: enameled wires, wrapped wires, special winding wires, and inorganic composite winding wires.

ISO Certificated Polyimide Round Enamel Coated Magnet Wire has better performance than all other types of enameled wires. Polyimide paint film has only abrasion resistance slightly worse than polyester and polyvinyl acetal enameled wires. In order to improve this performance, most of the current Use polyester imide and polyamide imide to prepare enameled wire, which can increase the solid content of the paint, but the heat resistance is somewhat reduced.

Enameled Copper Coating Aluminum Wire refers to the wire with aluminium core as the main body and a certain proportion of copper coating on it. It can be used as conductor of coaxial cable and conductor of wire and cable in electrical equipment.Polyurethane enameled wire; thermal grade 130, 155, 180, 200. It is characterized by direct welding, good high frequency resistance, easy coloring and good moisture resistance.

In recent years, the price of electrolytic copper has continued to rise, which has brought a huge impact to the production of related copper wire raw materials and enameled wire suppliers. The use of copper-clad aluminum enameled wire has been proved by users to replace pure copper enameled wire, thus providing a huge business opportunity and a broad market for the development of my country’s enameled wire industry. The new type of Enameled Copper Coated Aluminum Magnet Wire For Voice Winding using copper clad aluminum material as the inner conductor has characteristics between copper and aluminum, combining the excellent conductivity of copper and the light weight of aluminum.

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.

First, my country has become the first big country of lacquer wire production and consumption. With the transfer of the world manufacturing center, the global enameled wire market has also begun to China, China has become an important processing base of the world, especially after China’s accession to WTO, my country’s enameled wire industry It also achieves rapid development, the production of enameled wires has exceeded the US and Japan, which became the world’s first production big country and consumer. As the economy is constantly increasing, the export of the downstream industry in the enameled wire has also increased year by year, and the enameled wire industry has entered the international market. The subregional aggregation is remarkable.

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.

Electromagnetic wires used to make motor windings can basically be divided into two categories: enameled wires and wound wires, in addition to inorganic insulated electromagnetic wires. Improve the electrical and mechanical properties of the magnet wire, improve its solvent resistance, heat resistance, and reduce the thickness of the insulation, which can greatly increase the slot full rate of the motor. The slot full rate is the ratio of the total cross-section of the conductor in a slot of the motor to the cross-sectional area of ??the slot, or the filling factor of the slot. This value is of great significance for reducing the volume and weight of the motor.

The environmental painted wires of the lacquer formula contains the shortening project development time, saving project funding, and significantly improving the quality of the project.

Enameled wire coating is mainly used for coating and insulation of enameled wire cores. Since the wire will be subjected to heat, chemical and various mechanical forces in the process of winding coils and embedding wires, the enameled wire paint is required to have good coating properties (that is, uniform coating), and strong paint film adhesion.

What is called Magnet Wire? The magnetic wire is a copper wire with an enamel (a kind of paint ) coating on it, and used for transformer coils and motor coils. Copper wire is a conductor, like bare copper.

Double Glass-fiber Covered Rectangular Aluminum Wire is a kind of winding wire made by electrician round aluminum rod drawn or extruded into a rectangular conductor by a certain specification die, and then a double glass fiber insulation layer is wrapped on the rectangular conductor.

The multi-shaped enamel wire refers to a metal wire for winding electromagnetic coils with an insulating paint, also known as electromagnetic wires. The multi-shaped enameled wire is the primary raw material of electrical, motor and household appliances, telecommunications, electronic external electromagnetic windings. In the future, follow the rapid development of industrial appliances, household appliances, telecommunications, electronic products, etc. Market and application fields.

Aluminium Alloy Wires are made from a wide range of aluminum alloys, depending on the customer requirements. Aluminium wires are sold to manufacturers of eyelets, rivets, nails, screws and other various products. Bare Aluminium Wire is used for Cables, Junctions, Rivets, Hangers, Clips and other household Items.

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.

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
The insulation of enameled wire is varnish film, which is formed by coating insulating varnish on the conductive wire core and drying it.
