In North America, aluminum is the predominant choice of winding material for low-voltage, dry-type transformers larger than 15 kilovolt-amperes(kVA).

In most other areas of the world, copper is the predominant winding material. The primary reason for choosing aluminum windings is its lower initial cost.

The current enamel wire industry is relatively low due to the admission threshold, and therefore the production enterprises have more and more, and the market competition is constantly intensified, but in the high-end product field, there are not many companies that can enter, in the present, and future, The enamel wire business wants to achieve better development, and build brands and scale becomes more and more important.

Anti-electricity-firecable wire
2. Aluminum winding wire
3. Three-layer extruded insulation wire

The lacquered wire is composed of two of the conductor and the insulating layer. After the bare wire is deck, after multiple painting, baking.The enameled wire can be used in transformers, motors, motors, electrical, ballasts, inductance coils, disadvantages, audio coils, microwave coils, electric fans, instrumentation, and the like.

What is the first thing to make the enamel wire? And the manufacutring process of enameled wire is important, the extruding and baking. And the raw materials: copper conductor or aluminum conductor is enough for client’s requiremnets

The paint is a process of painting the paint of the enameled wire to form a uniform lacquer layer of a thickness on the metal conductor. This is related to several physical phenomena and painting methods of liquid.

In the long-term thermal aging test, three or more temperature points are usually selected for accelerated aging, commonly known as “three-point aging”.

The samples for the aging test are stranded enameled wire pairs. The production of the stranded pairs should meet the requirements of ASTM D2307 or NEMA 1000 standards, including the weight to be applied when making the stranded pairs, the number of twisted turns, the effective length of the stranded area, and The length of the two ends of the twisted pair, etc. When making a twisted pair, the required force and the number of twist turns will vary depending on the diameter of the wire. The effective length of the stranded area has nothing to do with the wire diameter, the effective length is 121¡À6 mm, and the two ends are at least 50 mm long. At least 10 twisted pairs per temperature point and mounted on twisted pair racks for high temperature aging test.

The infrared spectrum analysis test is based on the standard UL746A, which only confirms the chemical composition of the paint film, establishes the infrared spectrum and retains it. After the enameled wire is certified, samples will be sampled for testing every year during the follow-up inspection service. The infrared spectrum made by the paint film on the sampled sample needs to be compared with the infrared spectrum established on the sample at the time of certification. The two infrared spectrums must be comparable. superior.

In terms of enameled production equipment, the wide application of low energy consumption, low emission and high-speed wire drawing enameling machines has made our country in the forefront of the world in this field.

Due to its own characteristics, hollow coils have been widely used in voice coils in the electro-acoustic industry, deflection coils in precision instruments, combined coils in micro motors, and micro coils in sensors. Self-adhesive enameled wire has increasingly become the main wire type used in the coil winding process due to its excellent heat resistance, insulation, adhesion durability, easy molding, and simple winding process

The samples for the dielectric strength test are also twisted pairs, and the number is 5 pairs. During the test, the voltage was applied at a boosting rate of 500V/S until breakdown, and the voltage at the time of breakdown was recorded. The requirements for dielectric strength in the NEMA MW1000 standard will vary according to different wire diameters, different paint film thicknesses, and different enameled wire types.

High-voltage motors need to use diimide, monoimide, single-thin double-wire and other wire-wrapped flat wires of various specifications according to the voltage level. The straight part is 25 cm, and the maximum coil straight part is 1.2 meters. The winding can be single flat winding, single vertical winding, double flat transposition winding, or double flat transposition vertical winding, which is determined according to specific requirements. Round enameled wire coils can also be wound using the universal adjustment in the disc. The winding machine has a built-in speed regulating motor and a turbo reducer, which drives the winding machine to achieve 0-120 rpm reversible and brakeable rotation, and can count forward and reverse, generally 1600KW can be wound All kinds of motor coils within the range are also equipped with a set of simple tensioners, which can control the tightness of the winding coils. General repair manufacturers can choose the above products. If they encounter special large-scale specifications, they can choose special type windings. equipment.

As one of the main raw materials of winding wire, enameled wire enamel is a unique insulating material for enameled wire and an essential core material. The demand for enameled wire paint also indirectly reflects the demand for winding wire to a large extent, and most varieties of enameled wire paint are almost exclusively produced for enameled wire. In the past ten years, the production of global enameled wire enamel has gradually shifted to Asia. The fundamental reason is that the main demand is in Asia, and the most important one is China. China is currently the world’s largest producer and seller of enameled wire and enameled wire paint.
It is estimated that the total annual demand for enameled wire paint in the world is about 300,000 to 350,000 tons, and China is about 200,000 to 250,000 tons.
