What is a lacquered wire?

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

Three-layer insulated wire structure
High-frequency transformer triple-insulated wire is a high-performance insulated wire, so as the name suggests, this wire has three insulation layers with a core wire in the middle.
The first layer The first layer is golden yellow polyamine film, its thickness is a few microns, but it can withstand 3KV pulse high voltage
The second layer is a spray paint coating with high insulation,
The third layer is a transparent glass fiber layer. The total thickness of the insulating layer is only 20-100um. Its advantage is high insulation strength, and any two layers can withstand a safe voltage of 3000V AC, and the current density is large.

Paper insulation enameled transposition conductor characteristics:
1. There is no circulating current, the eddy current loss in the coil is small, and the current density can be improved;
2. Simplify the winding process;
3. The full rate is higher than that of the paper-covered wire slot.

Paper-insulated enameled transposed wires are mainly used in the coils of large transformers.

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Gauge (often abbreviated to Standard Wire Gauge or SWG) is a unit for denoting wire size given by BS 3737:1964 (now withdrawn).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

Enameled round aluminum wire is made of oxygen free rod or electrical aluminum rod by a certain size of the die drawing or extrusion of the wire, the insulation paint through many times of the winding wire. Mainly used in winding of transformers, motors, generators, and various electrical devices.

enameled aluminum wire is composed of aluminum conductor and insulation materials, which is insulated with a thin film or coating and creates a magnetic field when the wire is would in a coil and power is applied. Aluminum Conductor is main type of enameled wire.

The wrapped wire is made of natural silk, polyester fiber, glass fiber, insulating paper or synthetic resin film, etc., tightly wrapped on the conductive wire core to form an insulating layer. There are also insulating layers wrapped around the enameled wire. In addition to thin-film insulation, others such as glass filaments need to be dipped in adhesive insulating varnish to improve their electrical, mechanical and moisture-proof properties. In fact, they are combined insulation.

Copper paint package wire production process principle

Copper lacquer wires are coated with respective lacquer solutions, and then cured by solvent volatilization and paint film.The earliest enamel wire is oily painted wire, made from tung oil.Its paint film is abrasion resistant, and cannot be used directly to make motor coils and windings, and the cotton yarn can be added to the layer.Later, polyethylene glycol formaldehyde lacquer wire came out, and its mechanical properties were greatly improved, which can be used directly for motor windings, which is called high-strength enameled wire.

With the continuous progress of society and the continuous development of industry, enameled wire has a very broad application field and has become an indispensable main supporting raw material for products such as motors, electrical appliances, household appliances, electronics, communications and transportation, especially in recent years.
