ガラス繊維で覆われた絶縁された丸型/平型/正方形のアルミニウム/銅線

General types:

1. Single glass fiber copper / aluminum flat wire

The structure of single glass and double glass enamelled round aluminum wire flat aluminum wire winding is basically the same as that of glass wire, except that the bare wire is replaced by enamelled wire. This type of winding wire is “reinforced insulation”, which is applicable to the windings of motor electrical products with high working voltage and high reliability requirements. For example, single glass enamelled round copper wire can be used for motor windings in severe working environments such as mines. There are 130-220 different temperature indexes for the lacquer “core”, but since the maximum temperature resistance index of the bonding lacquer is 180, the temperature index of this type of winding wire is only 130, 155 and 180.

2. Double glass fiber copper / aluminum flat wire

For double glass filament coated wire, glass filament and polyester filament are generally used to dip and coat the corresponding special paint for glass filament coated wire for continuous winding coating, which needs to be dried. The double glass fiber needs to be coated twice in both directions of rotation. It is generally used for large electrical appliances such as transformers and welding machines.

Double glass filaments can also cover enameled wires, so that both the pressure resistance characteristics of enameled wires and the heat resistance characteristics of glass filaments can be obtained. Double glass wire wrapped wire is a copper wire wrapped with a layer of glass wire for insulation.

3. Glass fiber wrapped film wrapped wire

The insulation structure of this type of winding wire is first wrapped with film on the wire, and then wrapped with single or double glass fibers. It shall be impregnated with incompatible insulation coating of the required thermal grade and baked to form a whole between the glass fiber, film and conductor. The product is characterized by relatively thin insulation thickness and high withstand voltage value. It is especially suitable for high-voltage motor windings with working voltage of 6kV and windings of other motors and electrical products. The temperature resistance index of this product is 130, 155 and 180/200. The wrapped polyester film with temperature resistance index of 130, the wrapped polyesterimide film with temperature resistance index of 155 and 180/200 or the polyesterimide F46 composite film (the insulation flexibility of the winding wire of the latter is better than that of the former), the film thickness is generally 0.05mm thick. If 0.02-50.03mm is used, the product with nominal insulation thickness of 0.02mm can be made by adding single glass fiber. Its breakdown voltage is not less than 2500V, and its insulation performance is better than that of enameled glass clad copper flat wire.

This product has voltage breakdown resistance and temperature resistance grades of 130, 155, 180 and 200. It is widely used for windings of reactors, transformers, motors or other similar electrical products.

The polyester film or polyimide film shall be overlapped by more than 30%, and the return of two layers of glass fiber shall be opposite. Class F wire shall be immersed in class F insulating paint, and class H wire shall be immersed in class H insulating paint

155 grade film wrapped wire (copper and aluminum): the insulation structure is formed by the bottom polyester film plus glass fiber and special wire wrapped insulation paint after high-temperature baking and curing. Compared with a single wire wrapped wire, it has excellent electrical performance, excellent wear resistance and high mechanical strength of the wire wrapped wire, and improves the environmental protection of the product. While ensuring excellent winding forming adaptability, transformers, motors Excellent performance in reactor and other fields.

Class 180/200 film wrapped wire (copper and aluminum): the insulation structure is formed by the bottom polyimide film plus glass fiber and special wire wrapped insulation paint after high-temperature baking and curing. Compared with a single wire wrapped wire, it greatly improves the electrical performance and temperature resistance of the product. At the same time, it has excellent wear resistance and high mechanical strength of the wire wrapped wire, and improves the environmental protection of the product. While ensuring excellent winding forming adaptability, It is prominent in the fields of transformers, motors, reactors, etc. where electrical and temperature resistance requirements are high.

4. Self adhesive glass fiber wrapped wire:

This kind of product is coated with self-adhesive paint on the surface of products 1, 2 and 3. For this reason, the winding turn bonding process can be simplified and the bonding quality can be improved. The thickness of the self-adhesive paint layer applied is not more than 0.03mm. This value can not be calculated in product design. When the paint layer is heated and pressurized, it is leveled and filled, but the thickness can disappear. It is a technological material. At present, self-adhesive paint is mostly applied on flat wires, which is more common. The temperature resistance index of this kind of products also has three grades: 130, 155 and 180.

Requirements for self-adhesive property: after heating the sample for 20min as required, the self-adhesive property shall be ≥ 2MPa; Temperature grade: according to different needs, there are 130,155,180 temperature grades.

Insulation thickness and breakdown voltage are as follows:
