Xinyu Self-adhesive Enameled Wires’ Characteristics

During the manufacturing process of Copper Enameled Wire , the motor windings are required to be immersed to fix the orientation of the coil. At present, there are two methods for impregnating the winding of the motor coil. One is that the winding is entirely immersed in the liquid resin (impregnating varnish), and the other is that the resin is dropped into the fixed portion of the coil. Both of these methods require baking and curing in order for the impregnation to truly demonstrate its skill and effectiveness.

The impregnation of the enameled wire first makes the coils themselves bonded into one body, so that the coils are insulated from the slots, and the silicon steel sheets are bonded together. Structurally, it can act as a fix; in terms of heat transfer, it can improve heat transfer and lower temperature rise. Although the above impregnation method can obtain a satisfactory effect, it also has the following deficiencies:

(1) The impregnation of the impregnated varnish for the inside of the tightly wound coil is generally unreliable and unpredictable, and there are often cases where bubbles and the substrate are not stuck, especially for high solids impregnating varnishes.

(2) The impregnating varnish enters the coil and then transpires the solvent by baking. Not only does the coil have more or less bad physicochemical effects, but also consumes a lot of heat energy, and the manufacture and repair of the impregnation equipment also requires a certain cost.

(3) The transpiration of the solvent will pollute the environment, which is not conducive to the health of the operator, and also has the risk of fire. Therefore, how to improve the impregnation process is a question of the constant demand research in the process of motor winding production.

Advantages and Applications of Xinyu Enameled Wire

Talking about the strengths of Enameled aluminum wire and its application field. Aluminum enameled wire has the following advantages DC resistivity: The DC resistivity of the copper clad aluminum wire is about 1.45 times that of the pure copper wire; the resistance phase together, the copper clad aluminum wire component. Outstanding solderability: The copper clad aluminum wire has the same congruence as the pure copper wire because of its concentric coating of pure copper. Brazability, not special treatment like aluminum wire; together, copper clad aluminum wire has a thick copper layer to ensure that when painting. Light weight: The copper clad aluminum wire density is 1/2.5 of the pure copper wire of the same wire diameter, which is very useful for the component of the falling coil. Replacing copper wire with Shenzhou copper-clad aluminum wire can save at least 30% of the cost.

Notes on the use of aluminum enameled wire

aluminum enameled wire is a signal transmission, but it is now a power transmission. It is very simple to question, and the life of its goods will be greatly reduced. In fact, in the use of aluminum enameled wire, pay attention to the oxidation maintenance of the undercut wire to ensure the useful connection between copper and aluminum, can be used for a long time.

There are many areas in which copper-clad aluminum wire and copper-clad aluminum enamel bags cannot be used. However, in fact, many companies use transformers, which is very worrying. The worry of the use of copper clad aluminum wire is 2 points, the self-resistance is higher than that of the cross-section copper, and the temperature rise is doubtful; the easy oxidation of aluminum wire will further increase the wire resistance and avoid oxidation.

The most worrying is the copper and aluminum in the Copper Enameled Wire, the metallurgical connection often said in the industry, the reliability in the long-term application process, in the process of thermal expansion and contraction, copper and aluminum contact can Whether it can withstand testing, there is no real proof in the industry.

Xinyu Copper Enameled Wire and Magnet Wire

As you know xinyu-enameledwire is a professional enameled wire supplier, we offer Copper Enameled Wire and enameled aluminum wire, welcome your visit.

Copper enameled wire is used in motor windings, transformer windings, induction coils, The insulation may be a thin film of varnish called enamel, a fibrous polyester or fiberglass yarn; or a combination of both enamel and fibrous insulations. The fibrous insulation may be impregnated with a varnish to bind the insulation to the conductor and enhance thermal endurance. If it is bare copper then, windings will result in short circuit, so an enamel coat is applied which acts as insulator & makes winding possible. This is done by making the copper dip in to enamel solution as it is “drawn” to required thickness / diameter and allowed to cure. Such enameled copper wire is called magnet wire.

However, Bare copper is used in electrical wiring & connections including grounding / earthing.

Magnet_wire is also called winding wire. There are a number of film insulation types ranging from temperature Class 105 to Class 240. Each film type has its own unique set of characteristics to suit specific needs of the application

Magnet wire shelf life is not established in commercial specifications. As long as the wire has been carefully stored it may be usable for years to come. Bondable wire should not be stored at temperatures exceeding 100°F. Electrolytic tough pitch copper (ETP Copper, UNS C11000) exceeds 99.9% purity and is the most widely used type for magnet wire production. It is intentionally oxygenated (200-400 ppm) to achieve the best combination of conductivity, capacity for being cold worked and economy. MWS can also supply wire made from high purity (99.95%) OFHC Copper (UNS C10200) or Certified (99.99%) OFHC Copper (UNS C10100).

With many years of rich experience and professional technical support of Enameled Copper Wire , xinyu-enameledwire has won the favor of our customers and hopes that we can cooperate for a long time.

The Damage Reasons for Enameled Wire

The insulation is damp. This condition is also common and generally occurs at enameled wire joints in direct buried or drained pipes. For example, if the enameled wire joint is unqualified and the joint is made under humid climatic conditions, the joint will be filled with water or mixed with water vapor. For a long time, R forms a water branch under the electric field effect, which gradually damages the insulation strength of the enameled wire and causes problems.

Chemical corrosion. The Enameled Copper Wire is directly buried in the acid-base effect area, and the enameled wire sheathing, lead skin or outer sheath is often corroded. The protective layer is chemically corroded or electrolytically corroded for a long time, causing the protective layer to fail and the insulation to drop. The enameled wire is damaged; the corrosion of the enameled wire in the unit is quite serious.

Overloaded for a long time. Overloading, because of the thermal effect of the current, the load current will cause the conductor to heat up when passing through the enameled wire. The skin effect of the charge together with the eddy current loss of the steel stern and the loss of the insulating medium will also generate additional heat, and then increase the enameled wire temperature.

Enameled wire connector is faulty. The enameled wire connector is the thinnest link in the enameled wire line, and the enameled wire connector problem caused by the direct fault of the person (poor construction) often occurs. During the process of making the enameled wire joints, the construction personnel will cause the insulation of the enameled wire head to drop if there is a joint that is not tightly crimped or insufficiently heated, and then cause the incident. Environment and temperature. The external environment and heat source where the enameled wire is located may also cause excessive enameled wire temperature, insulation breakdown, and even an explosion.

So choose a professioal Enameled Wire manufacturer is very important, here i recommend you, we truly believe that long-term customer satisfaction is the foundation of our success. To keep fulfilling the changing needs of our valued customers, we have a complete supply chain management for high quality and service.
