Information about Enamelled copper wire
Enamelled copper wire is a copper wire coated with a liquid through a variety of varnish. It is based on product usage and resistant to heat up the product. In general, enamelled copper wire will be used in the electronics industry. It is used to produce electrical and electronic equipment of various types. For example, Transformer, Coil, Choke coil, Line filter, Reactor, Inductor, Motor, Generator, loud speaker, loud speaker, busbar and etc.
The enamelled copper wire will vary according to the implementation of the electrical and electronic equipment. The enamelled wire is applied to the industry for the manufacture of electrical and electronic equipment in the fields of electromagnetic navigation. The various types is depending on the type of liquid chemical used to make varnish coated copper wire to have a different to the resistant of the temperature.
