Wire enamel insulating varnish is a kind of paint that can produce a good insulation layer between the wires in the winding. It is mainly used for the outer layer of bare copper wire, alloy wire and glass wire covered wire of various wire diameters to improve and stabilize the performance of enameled wire.

Polyimide Kapton Covered Enameled Aluminum Wire Strip is a multi-layer polyimide & fluoropolymer dispersion-coated film. The fluoropolymer coating functions as a heat-fusible layer for bonding to magnet wire conductors. It has superior scrape abrasion resistance and exhibits lower frictional properties than wire insulated with other commonly used polyimide materials. Polyimide film aluminum wire is ideal for demanding magnet wire applications and for difficult-to-wind motors.

Heat resistance refers to the properties of a substance that can maintain its excellent physical and mechanical properties under heated conditions. The highest use temperature of commonly used materials to characterize. There are different standards and test methods for different materials. Such as plastics are generally expressed by Martin heat-resistant temperature. The coating industry uses a blast constant temperature oven or a high temperature furnace. After it reaches the specified temperature and time, the surface condition of the paint film is inspected, tested, or other properties such as impact, bending, water immersion, salt spray test, etc., and then before and after Test data representation. All coatings used in higher temperature occasions must use heat resistance as an important technical indicator of the coating film

Standards Of Enameled Wire includes
1）IEC 60317 for Europe
2）JIS C3202 for Asia
3）NEMA MW 1000C (inch) or NEMA MW 1000C metric (mm) for North America

Telephone cable is usually thought of only as a communication medium operating at a normal 48 Vdc level. But telephone cable is regularly used by telephone operating companies to supply power to remote telephony equipment such as: PCM (Pulse Code Modulation) repeaters, FDM (Frequency Division Modulation) repeaters, telegraph and various types of control circuits. The normal talk battery voltage is regularly exceeded in the case of long subscriber loops utilizing loop extenders and on dial long line circuits which operate in the 70 to 100 Vdc range. For these applications, the referenced devices are generally current limited to approximately 150 milliamps. In all such cases, normal telephone industry practice usually limits pair-toground applied voltage to 150 Vdc, and pair-to-pair voltage is usually limited to 300 Vdc.

The paper covered wire is a type of enameled wire that is extruded or pulled by an oxygen-free copper rod or an electrical circular aluminum rod, and then annealing the wire, and then winding two layers or two layers of insulating on the copper (aluminum) conductor.Paper (including telephone paper, cable paper, high voltage cable paper, turns], suitable for oil immersion transformer coils and other similar electrical windings.Electrical bare copper (aluminum) wires produced by extrusion process are the most ideal materials for the production of cable paper wraps.

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.

Enameled wire is a main type of magnet winding wire. It is composed 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

Copper-clad aluminum wire refers to a wire with aluminum core wire as the main body and a certain proportion of copper layer plated on the outside. It can be used as a conductor for coaxial cables and wire and cable conductors in electrical equipment. The aluminum wire has a small specific gravity, but its welding performance is not good. Therefore, the copper-clad aluminum wire is wrapped with a copper layer on the aluminum wire. This copper-clad aluminum wire can not only take advantage of the small aluminum specific gravity, but also improve the welding performance.

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.

Enameled wire coating is mainly used for coating and insulation of enameled wire cores. Since the wire will be subjected to heat, chemical and various mechanical forces in the process of winding coils and embedding wires, the enameled wire paint is required to have good coating properties (that is, uniform coating), and strong paint film adhesion.
