Nomex Paper Covered Copper Aluminium Enameled Wire

Copper-clad aluminum wire is made of a solid aluminum core covered with a copper skin in order to improve its performance in the field. Copper clad aluminum wire is very different from solid EC grade aluminum wire. For one, CCA belongs to a species of metals known as ¡°Bimetallics,¡±
Conductor materials: copper and aluminum

Enameled wire is used for camcorder, electronic clock, micro relay, automobile, electronic instrument, washing machine, TV element, etc. Development direction in the diameter, use the specification range of ¦Õ0.06 ~ 0.08 mm and all thickened insulation

The current enamel wire industry is relatively low due to the admission threshold, and therefore the production enterprises have more and more, and the market competition is constantly intensified, but in the high-end product field, there are not many companies that can enter, in the present, and future, The enamel wire business wants to achieve better development, and build brands and scale becomes more and more important.

Advantages of oxide film wire
1. The oxide film is not sealed by insulating paint, and the temperature resistance can reach 250¡æ. The heat resistance of the oxide film sealed with insulating paint depends on the temperature index of the insulating paint;
2. High slot full rate, light weight and good radiation resistance.

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

The infrared spectrum analysis test is based on the standard UL746A, which only confirms the chemical composition of the paint film, establishes the infrared spectrum and retains it. After the enameled wire is certified, samples will be sampled for testing every year during the follow-up inspection service. The infrared spectrum made by the paint film on the sampled sample needs to be compared with the infrared spectrum established on the sample at the time of certification. The two infrared spectrums must be comparable. superior.

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.

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.

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.

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

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.

Enameled Copper Coating Aluminum Wire refers to the wire with aluminium core as the main body and a certain proportion of copper coating on it. It can be used as conductor of coaxial cable and conductor of wire and cable in electrical equipment.Polyurethane enameled wire; thermal grade 130, 155, 180, 200. It is characterized by direct welding, good high frequency resistance, easy coloring and good moisture resistance.

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.

British Standard Wire Gauge (often abbreviated to Standard Wire Gauge or SWG) is a unit for denoting wire size given by BS 3737:1964 (now withdrawn). It is also known as the Imperial Wire Gauge or British Standard Gauge. Use of SWG sizes has fallen greatly in popularity, but they are still used as a measure of thickness in guitar strings and some electrical wire. Cross sectional area in square millimetres is now the more usual size measurement for wires used in electrical installation cables. The current British Standard for metallic materials such as wire and sheet is BS 6722:1986, which is a solely metric standard.

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.

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.

Correspondence table of enameled wire diameter and resistance value
The resistivity of the copper wire ρ= 0.0172, the aluminum wire ρ = 0.0283, the wire resistance calculation formula:
R=ρ×L/S
(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.

The selection criterion of the electromagnetic wire is not considered for resistance, as the problem of resistance and fever can be done by selecting the same cross-sectional wire, it is the main consideration of the thick wire or the thin wire is mainly considered Operability.

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.
