That's a good question. Let's start with the magnet wire. Magnet wire is copper wire coated with a special coating. The coating acts as an insulator, which allows the wire to be wound multiple times in the coil (loop). Maxwell told us that when a wire is wrapped in a coil, electrons passing through the wire create a magnetic field perpendicular to the flow of the current. A common device for this process is an electromagnet. So the answer to the question is; " Enameled copper wire ". The wire features thinner enamel, higher efficiency, smaller overall size, more packing per cubic centimeter, stronger magnetic effect, and more dense magnetic field.

enamel coating series consists of polyurethane, polyester, polyester imide, polyamide-imide. The solids content ranges from nearly 8% to 60% (1g/1h/180°C), and the viscosity ranges from 30 to 60,000 mPas (23°C).

Enameled wire also known as winding wire or electromagnetic wire, it is a general conductive material primarily used in applications requiring energy conversion and power transmission, including transformers, inductors, motors, generators, loudspeakers, hard disks, electromagnets and other applications requiring insulated coils. Copper's high conductivity makes it a perfect metal for electrical applications, and it can be completely annealed and electrolytically refined to provide tighter windings for electromagnetic coils. Despite the disadvantages of oxidation, low-cost aluminum as a conductor is gradually accepted for its high performance. One to four coats of insulation are applied to the wire, this protects the wire from current contact with other wires, prevents short circuits, and extends the life, efficiency, and application of the wire. Enameled wire is used to convert electrical energy into other forms of energy in a wide range of applications.

There are two types of transformer voltage regulation: on-load voltage regulation and no-load voltage regulation.

The different properties of wires in transformers are due to the differences in materials, that is the conductive characteristics of copper and aluminum. Specific performance in the following aspects.

Transposing wire (RTC) is a composite wires consisting of 5-80 enameled copper flat wires that are combined to allow wide faces to contact each other and are wrapped in a 0.08 to 0.12mm insulating shell made of paper or other fibrous material. The main categories are polyester rope, hardened type and self adhesive type products. It can be suitable for any working position in CTC cable, up to 120x26mm, can work stably in 240 degrees high temperature environment, and most of the transposition wire (RTC) is used in power transformers, electrical equipment, transmission and distribution centers, military and defense industries.

LP Industry Aluminum is specialized in manufacturing aluminum strip roll with high quality on surface and edge. In the production process of aluminum strip, the problem of surface scratches is often encountered.

Choices include products that use a polyvinyl formal resin, polyimide resin, or polyamide resin; polyurethane base insulation enamel; or film insulation with a modified polyester basecoat and nylon topcoat.

Variety requirements for enameled wires in various industries,

Electromagnetic wire: cutting the magnetic field line in the magnetic field to generate an induced current or a magnetic field through the current to realize the mutual conversion of electrical energy, magnetic energy and mechanical energy.

Magnet wire is divided into Enameled wire, Winding wire, Enameled Winding wire and Inorganic Insulated wire according to the Insulating Material and manufacturing method used for the electrical insulating layer.
