Three-layer insulated wire

Poor soldering is mainly manifested in that the paint film after soldering will not melt off after the soldering, which causes the phenomenon of poor soldering.

Generally speaking, UL certified enameled wire needs to do four tests:
Thermal Aging Test (Full Thermal Aging Test or One Temperature Thermal Aging Test)

An electrical motor is one kind of machine which is used to change the energy from electrical to mechanical. Most of the motors work on the principle of interaction among the electric current as well as the magnetic field within a wire winding. This can generate force in the form of shaft rotation. These motors can be powered with DC or AC sources. The DC sources are batteries whereas the AC sources are inverters, power grids, generators. A generator is mechanically similar to the motor but works in the reverse direction by converting the energy from mechanical to electrical. An electric motor can be built with the rotor, stator, air gap, windings, bearings, & commutator. The classification of motors can be done with considerations like the type of power source, construction, motion output type, and applications. This article discusses what is a motor winding, types, and its calculation.

Speaking of the copper enameled wire, I believe everyone should know. Today, we introduce you to a wire, ie the copper paint package. Let us simply look at the transportation and preservation of copper-clad aluminum wires, because if many wires are transported incorrect, it is very likely to be used, so let us simply understand the transportation and preservation of the copper paint wire, so you can be here.

1. Different materials: structure and composition are different
2. Different performance: Since the three-layer insulated wire cannot be directly welded, it needs to be stripped first, and the cost is higher, and it will be replaced by FIW; the insulation level is different, and the three-layer insulated wire can be produced with a temperature resistance of 200 degrees
3. Can be different in color, etc.

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) .

Produced by the extrusion process electrical bare aluminum wire is wrapped production of the cable wire is the best material.

Glass-fiber covered aluminum magnet wire used to have weak coating strength (abrasion resistance, shock resistance, and flexibility). However, that disadvantage has been significantly improved recently by refining material selection and manufacturing methods. The demand for glass-fiber covered aluminum magnet wire is increasing as the wires have excellent uniformity and electrical properties under high temperatures and humidity.

¡ñ Conductor resistance. Measure with a conductor resistance tester, and then change to the value at 20¡ãC for comparison.
¡ñInsulation destruction voltage. Twist two enameled wires, apply voltage between the conductors, and judge by the damage voltage of the paint film. This performance is analyzed and judged through two tests of normal state and cold state breakdown voltage.
¡ñPaint film continuity (pinhole). Check the small holes of the paint film with a certain length of the test material. The project is tested by a high-pressure paint film continuity tester.

1. Conductor resistance ¡ª The resistance of a conductor is proportional to its length and inversely proportional to its cross-sectional area.
2. Conductivity¡ªBased on the resistance 1/58ohm (0.017241 ohm) of a standard soft copper wire with a length of 1m and a cross-sectional area of 1mm2 at 20¡æ, it is called 100% conductivity. The greater the resistance, the lower the conductivity, and the two are inversely proportional.
3. Bending resistance¡ªfix one end of the single wire, add weight to the other end to make it vertically downward, and then bend it back and forth 180 times until the wire breaks. The more bending times, the stronger the bending resistance.
4. Tensile breaking force¡ªthe maximum load weight or force applied to the specimen to break it during a tensile test.
5. Tensile strength¡ªthe breaking force per unit area to bear when the sample is broken during the tensile test.
6. Elongation ¡ª the ratio of the length of the sample after being stretched until it breaks to the original length at the specified standard distance. Conductors have different impedances at different temperatures.
Generally, 20¡ãC or 25¡ãC is the standard. The higher the temperature, the greater the impedance.

Wire for winding used in electrical equipment is generally called magnet wire. Simply put, ¡°Magnet wire is used for interchanging electrical energy with magnetic energy¡±.
Magnet wires are broadly divided into enamelled wire (coating insulation), covered conductor wire (fiber/film insulation), other specially formulated wire, and combinations thereof.

The AWG tables are for a single, solid and round conductor. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor. Because there are also small gaps between the strands, a stranded wire will always have a slightly larger overall diameter than a solid wire with the same AWG.

The current mainly passes along the copper-clad aluminum wire on the surface of the wire, which is called the skin effect. The higher the frequency, the more obvious it is. The copper-clad aluminum wire uses this feature to save material. But its resistivity is slightly higher than that of pure copper wire, and the resistivity is also different with the thickness of the copper clad.
