After the temperature resistance level is exceeded, the insulation layer will age, melt and crack. The result is that the insulation capacity is greatly reduced, and it is prone to increased loss, short-circuit failure, etc.

Paper insulation enameled transposition conductor characteristics:
1. There is no circulating current, the eddy current loss in the coil is small, and the current density can be improved;
2. Simplify the winding process;
3. The full rate is higher than that of the paper-covered wire slot.

Paper-insulated enameled transposed wires are mainly used in the coils of large transformers.

Enameled wire is a main type of winding wire. It consists of a conductor and an insulating layer. After the bare wire is softened by annealing, it is painted and baked many times. However, it is not easy to produce products that not only meet the requirements of the standard, but also meet the requirements of customers. It is affected by the quality of raw materials, process parameters, production equipment, environment and other factors. Therefore, the quality characteristics of various enameled wires are different, but they all have Mechanical properties, chemical properties, electrical properties, and thermal properties are four major properties.

Question: During our production process, we found that one axis of enameled wire is wound around the axial inductance. This axis of enameled wire and other axis of enameled wire are wound on the same magnetic core. The inductance of the enameled wire with this axis is relatively high. We made 1mH inductance, and the enameled wire of the other axis was only 960uH, and the problematic wire of this axis was 1.025mH, and the inductance test frequency was 796kHz. (1) The number of stitches is the same as the number of turns, excluding the slip ring. (2) The 1-meter straight resistance is a bit smaller than that of other shafts. I personally think that the enameled wire contains magnetic substances, but if it contains magnetic substances, the resistivity should be greater, and the DC resistance should be greater. So please help to solve the problem, or have encountered this kind of problem before, please analyze it, thank you in advance!

Advantages of enameled CCA wire:
As envelope alternatives of pure enameled copper wire, it has good performance of high frequency transmission, originally it was applied in various types of high-frequency electromagnetic induction coil; now in order to save more production cost, ECCA wire has been widely used in various types of electronic coils, transformers, inductors, rectifiers, and all kinds of large and small motors, and has excellent soldering performance. Its density is low, the weight of the unit product can at least save 40% of the copper wire, it can save a lot of cost of production material.

Electromagnetic wires used to make motor windings can basically be divided into two categories: enameled wires and wound wires, in addition to inorganic insulated electromagnetic wires. Improve the electrical and mechanical properties of the magnet wire, improve its solvent resistance, heat resistance, and reduce the thickness of the insulation, which can greatly increase the slot full rate of the motor. The slot full rate is the ratio of the total cross-section of the conductor in a slot of the motor to the cross-sectional area of ??the slot, or the filling factor of the slot. This value is of great significance for reducing the volume and weight of the motor.

The enamel wire is a major variety of winding wires, composed of two conductors and insulating layers, after the naked wire is deck, and then painted, baked.However, it is not easy to produce products that meet the standard requirements, but also meet customer requirements, it is affected by factors such as raw materials, process parameters, production equipment, environment, and therefore, the quality characteristics of various enameled wires are different, but they haveFour major properties of mechanical properties, chemical properties, electrical properties, and thermal performance.

(L = wire length, unit: meter, S = wire cross section, unit: mm^2)

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.

What is called Magnet Wire? The magnetic wire is a copper wire with an enamel (a kind of paint ) coating on it, and used for transformer coils and motor coils. Copper wire is a conductor, like bare copper.

Transformer insulation wire is usually circular. Silk covered wire, also known as cotton covered wire, it is a thread or yarn on copper coated insulation materials, such as to increase the mechanical strength and dielectric strength of the wire.

1. Cutting
The enameled wire is composed of a conductor and an insulator, and the hardness of the two parts is very soft, so it can be cut by using a TabCUT-200 precision cutting machine with a general SiC cutting chip. Since the insulator is coated on the conductor, and its hardness and ductility are quite different, and the insulating layer has a certain degree of peeling, it is better to use some soft materials such as tin foil, rubber, etc. to wrap the cutting part when cutting. Up to prevent the insulation layer at the fracture from peeling off after cutting.

The enameled wire paint coats up to 30 layers of copper and aluminum wires to provide electrical insulation and help avoid short circuits in the coil. Such enameled wire paint must also have excellent chemical resistance and high temperature resistance, must have excellent adhesion with copper or aluminum wires, and also have excellent mechanical stability.
In some cases, such as for motors driven by frequency converters, a suitable insulation layer should be able to resist partial discharges that may cause short circuits and malfunctions in the engine.

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
