The enameled wire industry is currently changing the traditional problems of low industry concentration and widespread low-end products. In the future, it will gradually increase R&D investment in the direction of high-end enameled wire and special enameled wire, and integrate and match with the transformation and upgrading of my country's manufacturing industry on the raw material side. With the adjustment of China's industrial structure, it will bring a new round of growth driving force to the enameled wire industry, and at the same time, product quality and industry concentration will also be further improved.

Enameled Wire Product Overview

Enameled wire is a main type of winding wire. It is made of a metal conductor as a conductive inner core and coated with a polymer insulating layer. It is mainly composed of these two parts; it is the conversion of electromagnetic energy into mechanical energy, heat energy, sound energy, light energy or mechanical energy. Functional materials that convert , heat, chemical, sound, light and other energy into electromagnetic energy.

It is the main material for winding electromagnetic coils in industrial motors (including motors and generators), transformers, electrical instruments, electrical and electronic components, power tools, household appliances, and automotive appliances.
The conductor part of the enameled wire is generally annealed undoped pure metal, such as copper and aluminum. In some occasions, copper alloy, gold, silver, nickel, stainless steel and other materials are also used. Polymers such as polyester, polyester, polyesterimide, and polyimide are often used as insulating film materials for the metal wires of electromagnetic coils.

The upstream of the enameled wire is the copper rod industry, and the downstream is various consumer terminals, mainly motors and transformers. Enameled wire is a kind of winding wire (magnet wire). Winding wire is a conductive metal wire with an insulating layer, which is used to wind coils or windings of electrical products. Its function is to generate a magnetic field through the current, or cut the magnetic force line to generate an induced current, so as to realize the mutual conversion of electric energy and magnetic energy, so it is also called electromagnetic wire.

The conductive cores of winding wires include round wires, flat wires, strips, foils, etc. At present, most of them use copper wires, and some use aluminum wires. In order to improve the tensile strength of aluminum winding wires, high conductivity and high strength aluminum alloys can be used. . According to the characteristics and uses of the insulating layer, winding wires can be divided into three categories: enameled wires, wrapped insulated wires, and special insulated winding wires. Wrapped wires include: paper-wrapped wire, glass fiber-wrapped wire, film-wrapped wire, special wrapped wire for submersible motor, winding wire for wind power generator, wire-wrapped single wire, wire-wrapped wire, transposition wire; special winding wire : Refers to winding wires suitable for special occasions or with special performance requirements.

Enameled wire production process

The production process of enameled wire mainly includes: unwinding, annealing, painting, baking, cooling, and winding.

The future development of the enameled wire industry is mainly reflected in three aspects:

First of all, the concentration of the industry has been further improved. As my country's economy has entered the new normal, the growth rate has slowed down, and all industries are facing the problem of overcapacity. Eliminating backward production capacity and closing polluting enterprises are the policies and guidelines vigorously promoted by the state. At present, my country's enameled wire Manufacturers are concentrated in the Yangtze River Delta, Pearl River Delta, and Bohai Bay region. There are more than 1,000 companies in the industry, but there are more small and medium-sized companies, and the industry concentration is low. With the acceleration of the upgrading of the industrial structure in the downstream field of enameled wire, the integration of the enameled wire industry will be promoted. Only enterprises with good reputation, certain scale and high technology level can stand out from the competition, and the industry concentration will further increase.
Secondly, the adjustment of industrial structure is accelerated, technological upgrading and demand diversification are the triggering factors to accelerate the adjustment of enameled wire industry, which makes ordinary enameled wire maintain a stable growth state and vigorously promotes the rapid development of special enameled wire.
Finally, energy saving and environmental protection have become the direction of technological development. The country pays more and more attention to environmental protection, energy saving, green innovation, and the enameled wire production process will produce a lot of pollution. Many enterprises' equipment technology is not up to standard, and the pressure on environmental protection is also increasing. Research and development, and the introduction of environmental protection equipment, it is difficult for enterprises to survive and develop for a long time.
