The Practical Application Process of ECCA Wire

From the perspective of the cable plan, the benefits of the ECCA Wire(XINYU-ENAMELEDWIRE) are very optimistic in the actual application process. The ECCA wire group is light in weight, which will bring great convenience to cable transportation and cable racking. Other ECCA wire is softer in material, and cables made with ECCA wire are a little softer than other cables. Then let’s talk about how to buy ECCA wire:

(1) The most important thing to do first is to check the material of the product at the time of purchase of the ECCA wire. How to identify the material of the ECCA wire? If the insulation and sheath are elastic, whether the appearance has burrs or protrusions, whether the surface should be smooth, round, and symmetrical; whether the copper-aluminum core can reach the requirements, and the conductor resistance should be tested when conditions exist.

(2) When initiating the purchase of brand-name products of the ECCA wire, the quality control of the ECCA wire’s own products should be stricter, and there must be a certain guarantee for the product’s wind.

(3) Identification of products that are too fine for ECCA wire. When purchasing ECCA wire products, you should observe the product certificate to deal with the product model, specification, rated voltage, number of cores, production date, implementation scale, permit number, and other relevant information. The product appearance should be printed with the name and product. The continuity of the model and rated voltage, to verify whether the information related to the two is uniform.

(4) The length of the fine ECCA wire. The certificate has a length mark. You can first estimate the length of the circle of the finished package, and then count the number of turns of the wire to see if the length of the wire is “less than two pounds”.

(5) When selecting ECCA wire products, professional electricians who have experienced experience should be consulted to accept the wires that meet the cross-section size and voltage level according to their own electrical load.

Copper Clad Aluminum Winding Wire Is Transmitted on The Surface Layer of The Conductor

The outer layer of the Copper Clad Aluminum Winding Wire(XINYU-ENAMELEDWIRE) is pure copper or red copper, the thickness is small, and the core is aluminum metal. The frequencies of cable TV signals and mobile communication signals are very high, usually around 50-800 MHz. Due to the “skin effect”, high-frequency current is mainly transmitted on the surface layer of the conductor, and aluminum itself has good conductivity. Therefore, the copper clad aluminum composite material can be used instead of pure copper or copper to ensure the transmission efficiency of the cable.

The price of aluminum is lower than that of copper, and its density is less than one-third of that of copper. Therefore, the weight per unit length of wire can be greatly reduced, which is beneficial to the installation and construction of cables. Therefore, copper clad aluminum winding wires have broad application prospects.

Advantages of copper clad aluminum winding wires:

1. The metal copper is saved and the production cost is greatly reduced. Meanwhile, copper clad aluminum is used instead of pure copper, thus saving rare resources.

2. Copper clad aluminum is light in weight and low in density, which is convenient for transportation and installation and greatly reduces the labour intensity in network construction. The mass ratio of copper to aluminum is 3.3: 1, and the density of copper clad aluminum is only 37.3%~40.8% of that of pure copper.

3. The stability and reliability of coaxial cable signal transmission are improved. Aluminum is commonly used as the outer conductor for coaxial cables. Because the expansion coefficient of copper clad aluminum is closer to that of aluminum than that of pure copper, the connection failure caused by the mismatched expansion of the inner and outer conductors of the cable due to temperature changes is reduced.

What Classification Can Aluminum Magnet Wire Be Classified Into

Aluminum Magnet Wire(XINYU-ENAMELEDWIRE) refers to the magnet wire with aluminum as the core, and the magnet wire is used to manufacture insulated wires of coils or windings in electrical products. Also called winding wire. Magnet wires must meet the requirements of various applications and manufacturing processes. The former includes its shape, specification, ability to work at high temperature for a short time and a long time, as well as withstanding strong vibration in some occasions and centrifugal force at high speed, corona and breakdown resistance under high voltage, chemical corrosion resistance under special atmosphere, etc. The latter includes the requirements of stretching, bending and abrasion during winding and embedding, as well as swelling and erosion during impregnation and drying.

Aluminum magnet wires can be classified according to their basic composition, conductive wire core and electrically insulating layer. Generally, it is divided into aluminum enameled wire, aluminum wrapped wire, aluminum enameled wrapped wire and inorganic insulated wire according to the insulating material and manufacturing method used for the electrically insulating layer.

Enameled wire of aluminum magnet wire: coat the conductor with corresponding paint solution, and then volatilize the solvent, solidify the paint film and cool it. Enameled wires can be divided into polyester enameled wires, polyester-imide enameled wires, polyamide-imide enameled wires, polyimide enameled wires, polyester-imide/polyamide-imide enameled wires, corona-resistant enameled wires, as well as oil paints, acetal paints, polyurethane enameled wires, etc. according to the insulation paint used. Sometimes it is also classified according to the particularity of its application, such as self-adhesive enameled wire, cryogen-resistant enameled wire, etc.

The winding of magnet wire: An Important Variety of Winding Wire. Early use of cotton yarn and silk, known as yarn and silk wrap, was used in electrical machines and appliances. Due to the large insulation thickness and low heat resistance, most of them have been replaced by enameled wires. At present, it is only used as a high-frequency winding wire. In large and medium-sized winding wires, when the heat resistance level is high and the mechanical strength is high, glass wire wrapping wire is also adopted, and appropriate adhesive paint is matched during manufacturing.

Paper winding still occupies a considerable position in winding and is mainly used in oil-immersed transformers. The oil-paper insulation formed at this time has excellent dielectric properties, low price and long service life. In recent years, film winding has developed rapidly, mainly polyester film and polyimide film winding. Recently, there are mica tape coated polyester imine film coated copper flat wire for wind power generation.

What Is The Manufacturing Process of Varnish Wire

Varnish Wire(XINYU-ENAMELEDWIRE) is the main raw materials for motors, electrical appliances and household appliances. Especially in recent years, the electric power industry has achieved sustained and rapid growth. With the rapid development of household appliances, the application of varnish wire has brought about a wider range of fields, with higher requirements for varnish wire. So what is the manufacturing process of varnish wire?

First of all, in the production line, in the normal coating machine operation, most of the operators, energy and physical strength are on the production line, so that the operators have paid a lot of labor, and the line changing joints are prone to quality problems and operational errors. The effective method is a large capacity line. The key to this wire is to control the tension. When the tension is high, it is not only a thin wire, making the surface of the wire lose light, but also affecting the performance of varnish wire.

The purpose of the subsequent annealing is to change the crystal lattice of the conductor in the stretching process after a certain temperature, restore the softness required by the process after molecular crystal lattice rearrangement, and at the same time remove lubricant and oil pollution on the surface of the conductor in the stretching process, so that the conductor can be easily coated and the quality of varnish wires can be ensured.

Following is the process of coating a certain thickness of varnish on the metal conductor: baking, the conductor enters the oven after being painted, the solvent in the coating is evaporated first, then solidified to form a layer of paint film, and then the baking process of paint packaging is finished by painting, baking and repeating several times.

Finally, cooling, lubricating and winding, varnish wire coming out of the oven have a very high temperature, very soft paint film and very low strength. If they are not cooled in time, the quality of the varnish wire will be affected after the paint of the guide wheel is damaged. Lubrication of varnish wire is closely related to the tightness of windings. Lubrication requirements for varnish wires can make the surface of the varnish wire smooth, do no harm to the wires, do not affect the strength of the take-up reel, and do not affect the principle of user use; The purpose of collecting and finishing varnish wire is to make varnish wire continuously, tightly and evenly wound on the bobbin. The take-up structure needs smooth, low noise, proper tension and regular wire arrangement.

Characteristics and Precautions of Enameled Copper Clad Aluminum Wire

The Enameled Copper Clad Aluminum Wire(XINYU-ENAMELEDWIRE) uses copper clad aluminum material as the inner conductor, which is a new type of electromagnetic wire. It combines the excellent conductivity of copper with the light weight of aluminum, and its characteristics are between copper and aluminum. Enamelled copper clad aluminum wire is widely used in transformers, inductive electromagnetic coils, acoustic coils, electromagnetic wires for demagnetization coils, etc. It has high DC resistivity, light weight and good solderability. But at the same time, there are also several aspects that need attention.

Due to low cost, most enterprises use copper clad aluminum wire in power transmission and transformer, and enameled copper clad aluminum wire cannot be used in many fields. The resistivity of copper clad aluminum wire is higher than that of copper wire, and the problem of temperature rise is worthy of attention. In addition, aluminum wire is easy to oxidize, which will further increase the resistance. Measures to prevent oxidation should be taken during use to avoid losses. The enameled copper clad aluminum wire can be used for signal transmission, but it will cause great problems in power transmission and reduce the service life of its products. When in use, attention should be paid to protecting the section of enameled wire to prevent aluminum oxidation and ensure the effective combination of aluminum and copper, which can also prolong the service life. What needs most attention is that there is no real demonstration in the industry as to whether the copper aluminum bonding ability can stand the test during the long-term use of this new type of metallurgical bonding electromagnetic wire and the process of expansion with heat and contraction with cold.

However, enameled copper clad aluminum wire still has many advantages such as low cost, lightweight and excellent conductivity. Reasonable use and protection can prolong the service life and greatly reduce the cost.

Enameled Copper Clad Aluminum Wire Is A New Type of Electromagnetic Conductor

Enameled Copper Clad Aluminum Wire is actually a new type of electromagnetic conductor, which uses copper-clad aluminum material as its inner conductor. It is characterized by being between copper and aluminum, and combines the excellent conductivity of copper with the advantage of lightweight of aluminum. It’s DC resistivity: the DC resistivity of copper-clad aluminum wire is about 1.45 times that of pure copper wire; When the resistances are the same, the weight of copper-clad aluminum wire is about half that of pure copper wire. It has good weldability: because of its concentric coating, the copper-clad aluminum wire has a layer of pure copper, which has the same weldability as pure copper wire and does not need special treatment such as aluminum wire. At the same time, the copper-clad aluminum wire has a thicker copper layer, which can ensure that the welding performance of the product will not be affected when the paint is scratched.

Lacquered copper-clad aluminum wire is economical and affordable. Enamelled copper-clad aluminum wire is a kind of wire and cable with aluminum core instead of copper as the main body and a certain proportion of copper layer on the outside. Ac resistance is the main basis of current carrying capacity. According to the principle of skin effect, the surface of a single conductor is larger than the centre where the current passes through the centre of the conductor. In other words, the centre of the large-section conductor is within the circular area of the same conductor, and the centre of the circle is smaller than the current passing through the circumference. Therefore, it is most reasonable and economical to use different metal elements of the centre conductor and the circular conductor.

Comprehensive Properties of Practical Enameled Copper Clad Aluminum Wire

Firstly, the practical Enameled Copper Clad Aluminum Wire(XINYU-ENAMELEDWIRE) is introduced. The same layer is concentrically coated on the surface of aluminum or aluminum/hard alloy core material and is formed by drawing. The thickness of the copper layer is more than 0.55mm. The cable TV signal is transmitted on the surface of the copper layer over 0.008mm, which has a skin effect. High-frequency signals are transmitted on conductors. The enameled copper clad aluminum wire conductor can meet the requirements of signal transmission, and its transmission characteristics are consistent with those of copper bodies with the same diameter.

Pure copper is superior to enameled copper clad aluminum wire in mechanical properties because the strength and tensile rate of pure copper wire are higher than those of copper clad aluminum wire. There are different requirements in practical application. From the perspective of cable design, the pure copper conductor has better mechanical strength than the copper clad aluminum conductor, but the copper clad aluminum conductor is lighter than pure copper, which is convenient for cable transportation and cable erection construction. Cables made of enameled copper clad aluminum wire conductors are softer than cables made of pure copper.

However, it is concluded that a practical enameled copper clad aluminum wire has better overall performance than pure copper wire, which also helps users to save costs and relieve pressure on enterprises.
