Customized Color Enamelled Wire Varnished Resistance Wire for
Instruments
Detailed Description
Enameled wire is a main variety of winding wire. It consists of two
parts, the conductor and the insulation layer. The bare wire is
annealed and softened, and then painted and baked multiple times.
However, it is not easy to produce products that meet the
requirements of the standard and meet the requirements of
customers. It is affected by factors such as the quality of raw
materials, process parameters, production equipment, and the
environment. Therefore, the quality characteristics of various
enameled wires are different, but all have Mechanical properties,
chemical properties, electrical properties, and thermal properties.
Magnet wire or enameled wire is a copper or aluminium wire coated
with a very thin layer of insulation. It is used in the
construction of transformers, inductors, motors, generators,
speakers, hard disk head actuators, electromagnets, electric guitar
pickups and other applications that require tight coils of
insulated wire.
The wire itself is most often fully annealed, electrolytically
refined copper. Aluminium magnet wire is sometimes used for large
transformers and motors. The insulation is typically made of tough
polymer film materials rather than enamel, as the name might
suggest.
These enameled resistance wires have been broadly used for standard
resistors, automobile
parts, winding resistors, etc. using the insulation processing best
suited for these applications, taking full advantage of the
distinctive features of enamel coating.
Furthermore, we will carry out enamel coating insulation of
precious metal wire such as silver and platinum wire upon order.
Please make use of this production-on-order.
Polyurethane enameled wire lacquer was developed by Bayer in 1937.
Because of its direct solderability, high frequency resistance and
dyeability, it is widely used in electronics and electrical
appliances. At present, foreign countries are very concerned about
improving the heat resistance level of polyurethane enameled wire
without affecting its direct welding performance. In Europe, the
United States, and Japan, F-level and H-level polyurethane enameled
wires have been developed. Due to the rapid development of color
TVs, Japan's color TV FBT with a large length of salt-free
polyurethane enameled wire without pinholes has attracted the
attention of countries around the world, and it is still Japan's
leading.
The development of domestic polyurethane enameled wire is slow.
Although ordinary polyurethane lacquers are produced in some
factories, they are mainly imported because of poor processability
and surface quality. F grade polyurethane has also been developed
in China, but has not formed production capacity. Large-length
pinhole-free polyurethane paint has also been successfully
developed and put on the market. It is mainly used to make black
and white TV FBT coils.
