What are the functions of enameled wire?

According to the characteristics and uses of insulation, winding wires can be divided into four categories: enameled wires, wrapped wires, special winding wires, and inorganic composite winding wires.

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.

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.

The voltage resistance performance of enameled wire is mainly affected by several factors:
1. The thickness of the insulating layer, not much nonsense;
2. The degree of aging of the insulating layer and the degree of baking affect the withstand voltage.
3. The quality of the insulation layer is mainly the pinhole performance.

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Gauge (often abbreviated to Standard Wire Gauge or SWG) is a unit for denoting wire size given by BS 3737:1964 (now withdrawn).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 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.

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.

¡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.

Enameled wire
The insulation of enameled wire is varnish film, which is formed by coating insulating varnish on the conductive wire core and drying it.

Product features and uses
