Advantages of Xinyu Aluminum 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.

Uses of Xinyu Enameled Copper Wire

Xinyu Enameled Copper Wire is a main type of winding wire. It consists of two parts: the conductor and the insulating layer. The bare wire is annealed and softened. However, it is not easy to produce a product that meets the requirements of the standard and meets the requirements of the customer. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have Four properties of mechanical properties, chemical properties, electrical properties, and thermal properties.

As for the characteristics and uses of the enameled wire, the specific ones can be summarized as follows: Acetal enameled wire; thermal grades are i05 and 120, with good mechanical strength, adhesion, resistance to transformer oil and refrigerant resistance, but the product has poor moisture resistance, low thermal softening breakdown temperature, and durable benzene-alcohol mixed solvent. Defects such as weak performance, currently only a small amount is used for oil-immersed transformers, windings of oil-filled motors.

The enameled wire of polyester and modified polyester, the common polyester enameled wire, has a heat rating of 130, and the modified enameled wire has a heat rating of 155. The product has high mechanical strength, good elasticity, scratch resistance, adhesion, electrical properties and solvent resistance. It is the largest production in China, accounting for about two-thirds: 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.

Polyester imide/polyamide composite enameled wire, heat grade 180 This product has good thermal shock resistance, high softening breakdown temperature, excellent mechanical strength, good solvent resistance and refrigerant resistance, and the weakness is easy under closed conditions. Hydrolysis, widely used in motors, electrical appliances, instruments, power tools, electric dry-type pressure cookers and other windings.

Polyurethane enameled wire; heat grade is 130, 155, 180, 200. The biggest feature is that it has straight solderability, good high frequency performance, easy coloring and good moisture resistance. It is widely used in electronic appliances and 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 production of large-size lines has poor flexibility and adhesion, so the specifications for the production of this product are small and medium-sized.

Polyester imide/polyamide composite enameled wire, heat grade 180 This product has good thermal shock resistance, high softening breakdown temperature, excellent mechanical strength, good solvent resistance and refrigerant resistance, and the weakness is easy under closed conditions. Hydrolysis, widely used in motors, electrical appliances, instruments, power tools, electric dry-type pressure cookers and other windings.

Polyesterimide/polyamideimide composite layer Enameled Wire is currently used in a wide range of heat-resistant enameled wire at home and abroad, its thermal grade is 200, the product has high heat resistance, and also has anti-freezing agent, cold resistance and radiation resistance. Other characteristics, high mechanical strength, stable electrical performance, good chemical resistance and refrigerant resistance, and strong overload capacity. Widely used in refrigerator compressors, air conditioning compressors, power tools, explosion-proof motors and motors, electrical appliances used in high temperature, high cold, radiation resistant, overload conditions.

Xinyu Enameled Wire Devoted to Enameled Wire Development

For winding custom coils or very finely spaced rework, we always touch the electromagnetic wire. The magnet wire is very, very thin (0.1mm in diameter!) Copper wire, with very thin insulation layer. It is used in a range of electronic products, hacker attacks and applications. These are commonly used for winding transformers, inductors, motors or electromagnetic coils, speakers, hard disk head actuators, electromagnets, pickups, and so on. However, this line is also useful when you must perform PCB repair, wire jump, or direct welding to SMT pads.

This axis is ~11.5 meters ~ 38AWG thick magnetic line, just can do a few projects. We recommend a valve core for each engineer’s workbench. Like all electromagnetic wires, there is a thin layer of enamel insulation. Some people like to take it out with a small flame (a lighter, for example), but we’ve found an easy way to melt a piece of solder into the iron and then immerse it in small pieces for a second. Remove the wires, clean them up and tin them!

The enameled copper wire from is technically just an insulated copper wire coated with a tantalum insulation layer. However, the insulating layer is very thin and heat-resistant. This characteristic makes it very suitable for winding coils because each millimeter is considered important because of their thin thickness. Almost all copper lines are completely insulated, and it is now difficult to find uninsulated copper lines.

The two wires have the same conductivity, but the magnetic copper wire is especially coated with a thin, high heat-absorbing material instead of a copper wire. The thin insulating material helps to make more coils in small areas of motors, transformers, relays, etc., and absorbs heat. The common copper wire is insulated with a thick material and may require more area for more turns, so the winding will not work effectively and will be able to melt the insulation in the heat.

Thick plastic coating can be considered a waste of space to solve this problem, you can try other copper wires with ‘normal’ insulation, but you will soon find that the coil is too big or too small. Xinyu enameled wire devoted to Enameled Aluminum Wire development with all the society and make our efforts to the development of enameled wire.
