¡ñExcellent chemical resistance (except alkaline) and solvent resistance.
¡ñThe mechanical strength is comparable to synthetic resin (P.V.F.).
¡ñThe force rate and dielectric rate are comparable to U.E.W. enameled wire.
¡ñAlkali resistance and moisture resistance are better than synthetic resin enameled wire (P.V.F).

Enameled wire is a main type of winding wire. It is made of a metal conductor as a conductive inner core and coated with a polymer insulating layer. It is mainly composed of these two parts; it is the conversion of electromagnetic energy into mechanical energy, heat energy, sound energy, light energy or machinery Functional materials that convert energies such as heat, heat, chemistry, sound and light into electromagnetic energy.

The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification. The different classes are defined by NEMA, Underwriters Laboratories (UL), and IEC standards.

Water quality affects the production of lacquer wires?

The production water production water in the lacquered wire has a variety of uses, and like, the requirements for water quality are also different. Depending on the purpose of use, the water quality can be divided into: annealing furnace water seal water, equipment cooling water, lubricant manufacturing water, etc.

Generally speaking, UL certified enameled wire needs to do four tests:
Thermal Aging Test (Full Thermal Aging Test or One Temperature Thermal Aging Test)
Dielectric Strength Test
Elongation and Heat Shock Test
Infrared Analysis – IR

1060 Transformer Aluminum Strip Product Description:
060 transformer aluminum belt is a special purpose aluminum belt product produced for transformers. It uses high-purity aluminum substrate and aluminum deep-processed products formed by slitting aluminum coils with an aluminum content of more than 99.60%. The raw material of transformer aluminum strip is high-purity aluminum, which is rolled into thin sheet aluminum coils of different thicknesses and widths by a cold rolling mill, and then longitudinally slitted into aluminum strips of different widths by a slitting machine according to the application. It is an important raw material in industry. The main processing equipment of 1060 transformer aluminum strip is slitting unit, which can be divided into required length and width according to needs. Usually the transformer aluminum strip is slit according to the actual needs of the user, which can reduce waste, reduce processing procedures (without cutting), and save raw material costs.

7 type of enameled wire in accordance with insulation materials, list the thermal class, advatanges and application per type of enameled wire. Enameled wire types also can be divided into copper magnet wire and aluminum wire in accordance with conductor.

Paper-covered Aluminium magnet wire deliver excellent performance when used with oil such as transformer oil. A paper with a small hygroscopicity, mechanical strength, good permeability for oil, and high dielectric strength should be selected.

Application of Telephone cable paper covered insulated Aluminum magnet wire strip:
Paper covered Aluminum magnet wire is used in oil-immersed transformer and other similar electrical coil windings.

The enameled wire has always been a very important industry in the national economy, and with the continuous change and development of the market, the enameled wire industry is constantly adjusting, from the current perspective, the future of the entire enamel wire industry will move towards the future.

The structure of enameled wire is very simple, consisting of conductor and insulating layer. Because of its high dielectric strength, small footprint and good heat dissipation, it is widely used as a coil winding in motors and transformers.

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.

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 glass in Glass Fibre Conductor may be applied in woven tape form or as a continuous fibre. It has proved to be an efficient insulation providing coil winders with thermal stability, adequate electrical properties and good resistance to abrasion after varnishing. The glass is bonded with a varnish to improve dielectric strength and mechanical properties.

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.

Axalta today announced that it has reached a final agreement to acquire Anhui Shengran Insulation Materials Co., Ltd. (“Anhui Shengran”). Anhui Shengran is a leading manufacturer of high-quality enameled wire paint in China. Its products are widely used in consumer electronics, electric vehicles and industrial fields. Subject to the conditions of the agreement, the transaction is expected to be completed in the second quarter of 2021. Financial terms have not been disclosed.

The space factors of magnet wires are compared in the right figure. The space factors of enamelled wires are superior to those of other wires for winding, as are their electrical properties. However, more careful examination must be made of the following properties as compared with other wires.

The samples for tensile and thermal shock testing were 3 pieces of 254mm enameled wire.

First pull the enameled wire to the required elongation at a rate of 3.7-4.6 m/sec, then wrap the jerked sample around the mandrel, and then put the wrapped sample into the oven at the specified temperature for 30 minutes. It needs to be suspended in the oven. After leaving the oven, inspect the baked samples for cracking or peeling of the paint film. In this test, the diameter of the mandrel is usually 3 times the diameter of the enameled wire.

The specified temperature of the oven is set according to the temperature specified for the enameled wire of this ANSI Type in the NEMA MW1000 standard, which is usually the temperature grade of the enameled wire +20¡ãC.

The wire drawing metal processing technology can form fine lines on the surface of the metal material, which makes the metal more textured, and is used as a decoration by users and is well-loved. In the production process, the drawing lubricating fluid is indispensable in the drawing metal processing technology. It is widely used in the lubrication of the middle drawing, small drawing and micro drawing of enameled copper wire. So how to choose this kind of drawing fluid?

With the continuous progress of society and the continuous development of industry, enameled wire has a very broad application field and has become an indispensable main supporting raw material for products such as motors, electrical appliances, household appliances, electronics, communications and transportation, especially in recent years. The rapid development of household appliances, the advancement of electronic technology, and the rise of the communication industry have provided new space for the application of enameled wires, adjusted the application proportions in various fields, and will also put forward higher and newer technical requirements for enameled wires, and adjust enameled wires. The proportion of the structure. After joining the WTO, the enameled wire industry will face competition in the domestic and international markets, which adds a layer of thinking and pressure to corporate leaders.
