Enameled flat wire is a main variety of winding wire. It consists of conductor and insulating layer. After the bare wire is softened by annealing, it is painted and baked many times.
What are the structural features of the enameled flat wire?
How to identify the parameters of enameled flat wire?
How is enameled flat wire produced?
①Copper wire: Maintaining high consistency and high accuracy is the core element, and at the same time, it is necessary to improve the elasticity of copper wire to increase its flexibility.
②Insulation layer: First, subject to the existence of the enameled flat wire's own structure - the 90-degree R angle, the coating paint is easily affected by gravity during the coating process, and the super-intermediate diffusion leads to the thinning of the coating layer in the R angle area, making the consistency damaged.
③ The 800V high-voltage platform puts forward higher requirements for the anti-voltage breakdown performance of the insulating layer, which is reflected in the need to increase the thickness of the insulating layer and the corresponding adjustment of its formula to better adapt to the high-voltage platform.
1. Enameled flat wire symbol + code:
(1) Series code: enameled winding composition: Q
Paper Wrapped Winding Wire: Z
(2) Conductor material: Copper conductor: T (omitted) Aluminum conductor: L
(3) Insulation material: Y, A polyamide (pure nylon)
(4) Characteristics of conductors: Flat wire: B Round wire: Y (omitted) Hollow wire: K
2. Enameled flat wire level: enameled flat wire product model is named by the combination of Chinese Pinyin letters and Arabic numerals. Its composition includes the following parts. Combining the above parts together in order is the product model of enameled wire.
1. The special-shaped die drawing method is similar to the round wire production process, and the special-shaped wire drawing die with a rectangular hole type is used for drawing. However, this method can only produce flat wire with low aspect ratio, and it is easy to cause uneven deformation or even fracture of the alloy wire, which cannot produce products with high precision and surface quality.
2. The strip slitting method is currently the most common in China. This process uses a slitting unit to cut large-width strips to obtain narrow strips with a minimum width of about 3mm. The advantage of the strip slitting process is that the processing difficulty is small, and the processing cost is low in the case of large width. narrow wire. The second disadvantage is that the transverse tension during the cutting process is extremely easy to cause camber and wire kink, making the product unqualified. In addition, the products obtained by the slitting method must be packaged in a pan, and the large pan weight cannot be obtained by transverse winding.
3. The round wire flat roll rolling method requires that the material round wire be drawn to a certain precise wire diameter, and then flattened and rolled by multiple flat rolls. This process requires more expensive equipment investment and stricter production process, but avoids the defects of the above two processes, with uniform mechanical properties, straightness, good flatness, accurate specifications, and excellent surface quality. A necessary process for narrow, ultra-thin and fine flat wires.
Established in 2009,with registered capital of nearly 6 million dollars, Baiwei Electric is a manufacturer and exporter specializing in various magnet wires. There is a big variety of magnet wire including enamelled wire, paper covered wire, continuously transposed conductors and composite wire.
