III. The joint action of upstream and downstream industries determines the supply and demand pattern of enamelled wire
IV. Development status and trend Prospect of enamelled Wire Industry in China
Introduction to SMM: the enamelled wire industry is currently changing the traditional problems such as low industry concentration and low-end products. In the future, it will gradually increase R & D investment in the direction of high-end enamelled wire and special enamelled wire, and integrate and match the transformation and upgrading of China's manufacturing industry at the end of raw materials. With the adjustment of China's industrial structure, it will bring a new round of growth driving force to the enamelled wire industry. At the same time, product quality and industry concentration will also be further improved.
Overview and Development History of enamelled Wire in past Life and present Life
Enamelled wire is a main kind of winding wire, which is made of metal conductor as conductive inner core and coated with polymer insulation, which is mainly composed of these two parts; it is a functional material that converts electromagnetic energy into mechanical energy, heat energy, sound energy, light energy or mechanical, thermal, chemical, acoustic, 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, power and electronic components, power tools, household appliances, automotive appliances and so on. The conductor part of the enamelled wire is generally annealed undoped pure metals, such as copper, aluminum, some occasions also use copper alloy, silver, nickel, stainless steel and other materials, according to the working voltage and working temperature, the enamelled wire often uses polyester, polyester imide, polyimide and other polymers as insulating film materials to wrap the metal wire of the electromagnetic coil. There are many ways to classify enamelled wires, the main classification methods are as follows:
