The motor is a large user of enamelled wire; the rise and fall of the motor industry is very important to the enamelled wire industry. The transformer industry is also a large user of enamelled wire. With the development of the national economy and the increase in electricity consumption, transformer demand also increases.
Home appliances with enamelled wire are becoming a very huge market. The demand for low friction coefficient enamelled wire, compound enamelled wire, "double zero" enamelled wire, fine enamelled wire, and other types has increased significantly.
According to the analysis of industry experts, it is expected that the demand for domestic automobile enamelled wire will exceed 4 million km in the future, and its demand will continue to grow at a rate of about 10%.
Since the 1980s, to improve wire performance, companies have developed new functions and machining capabilities. The new variants include corona resistant, polyurethane, polyester imine, composite coating, and fine enamelled wires. Micro enamelled wire primarily targets electroacoustic equipment, laser heads, special motors, and non-contact IC cards.
Enameled copper wire is primary used in the construction of motors, electromagnets, transformers, and inductors. Its thin insulation layer prevents short circuits while allowing high-density winding.
Copper offers excellent electrical conductivity, thermal performance, and mechanical strength, making it the most efficient and reliable choice for electromagnetic windings compared to other metals.
Corona-resistant enameled wire is designed for frequency-adjustable motors, where high-voltage pulses can cause insulation breakdown. It significantly extends the lifespan of motors operating under high-frequency conditions.
In automobiles, enameled wire is essential for generators, ignition coils, electric power steering motors, and the drive motors of electric and hybrid vehicles.
Micro enameled wire refers to ultra-thin diameter wires used in micro-motors, electroacoustic equipment (like speakers and headphones), and laser head components where space is extremely limited.
