Flat enameled wire is a type of enameled wire. It is a winding wire made of oxygen-free copper rods or electrical aluminum rods that are drawn, extruded or rolled by a certain specification die, and then coated with insulating paint for many times. The thickness is from 0.025mm To 2mm, the width is generally less than 5mm, and its aspect ratio ranges from 2:1 to 50:1. Flat enameled wire has a wide range of uses, especially in the windings of various electrical equipment such as telecommunication equipment, transformers, motors and generators.

Winding wires used in electrical equipment are usually called magnetic wires. In other words, “magnetic wires are used to exchange electrical energy and magnetic energy.” Magnetic wire is roughly divided into enameled wire (insulation coated) and coated wire (fiber/film insulation) and their combinations. The two types of magnetic wires and their performance are very different. ASTM (American Society for Testing and Materials) B193, no more than 0.017241 ohm (square millimeter/meter), the film or coating should meet the latest version of ANSI, ASTM or NEMA applicable standards, and modify the specified resin. The modified resin is Chemically changed resin, or containing one or more additives to retain the basic chemical characteristics of the original resin to enhance certain performance or application characteristics, the coated conductor needs to meet all the required test requirements of the appropriate NEMA standard (UL certification project) .

The enameled wire manufacturer takes you to understand the high-temperature paint wrap of high-temperature paint wires, and it is necessary to judge, whether its appearance, size, and performance meet the technical standards of the product and user technical agreements. After the measurement, test, the technical standards of the product and the technical agreement of the product are compared to the requirements for qualified products, which does not meet the requirements for unqualified products.

ISO Certificated Polyimide Round Enamel Coated Magnet Wire has better performance than all other types of enameled wires. Polyimide paint film has only abrasion resistance slightly worse than polyester and polyvinyl acetal enameled wires. In order to improve this performance, most of the current Use polyester imide and polyamide imide to prepare enameled wire, which can increase the solid content of the paint, but the heat resistance is somewhat reduced.

The environmental painted wires of the lacquer formula contains the shortening project development time, saving project funding, and significantly improving the quality of the project.

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.

A brief introduction to the advantages and disadvantages of copper wire and aluminum wire:Same area:

1, copper wireis large load than aluminum wire . 2, copper wire is more flexible than aluminum wire. 3 copper wire is lower resistivity than aluminum wire. 4,copper wire is more stable than aluminum wire. 5, however, copper wirer price is 3.5 times higher than aluminum wire.

UL Certificated 220 High Thermal Class Oxidized Film Aluminum Wire and aluminum strip insulated with aluminum oxide film are used in the fields of electronics, missiles, nuclear reactors, aerospace and aircraft industries. The oxide film has high flexibility and is suitable for winding electromagnetic coils of various shapes and sizes. The use of round or rectangular aluminum wires and aluminum strips can save 50% of metal, so it has commercial value. For example, linear motors and medical equipment industries are widely used because of their light weight and low inertia. For rotating equipment, light weight can simplify the dynamic balance, thus reducing the vibration generated by the dynamic balance, thereby improving the sensitivity of the moving coil and its high-frequency response.

Use a hydrogen-oxygen flame welding machine to weld the coil lead wires of electronic devices such as motors, motors, and transformers.

working principle:
Water is composed of hydrogen and oxygen. In a specific electrolytic cell, water can be decomposed into hydrogen ions and hydroxide ions. The hydrogen ions move to the cathode to generate hydrogen gas, and the hydroxide ions move to the anode to generate oxygen. Hydrogen is a fuel. Oxygen can be used to support combustion. It can be ignited by a specific hydrogen-oxygen flame gun to form a hydrogen-oxygen flame, which can quickly weld the enameled wire.

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.

Although the quality of enameled wire depends to a large extent on the quality of raw materials such as paint and wires and the objective conditions of machinery and equipment, if you do not take a series of problems such as baking, annealing, and speed, and understand their interrelationships. , Do not master the operation technology, do not seriously do the touring work, stop and tidy up the work, do not do well in the process and hygiene, even if the objective conditions are good, it will not be able to produce high-quality enameled wire. Therefore, the decisive factor for good enameled wire is people’s sense of responsibility for work.

The coating is a process of forming a uniform coating layer of a coating wire to form a uniform coating layer on a metal conductor. This is related to some physical phenomena and painting methods of liquid.

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.
