Its insulating layer is usually a thin film coated with insulating varnish, which prevents the wire from conducting electricity or short-circuiting. In some cases, such as when soldering or connecting other electronic components, the insulating layer needs to be removed.
Thermal stripping is a common method of removing varnish, in which the insulation layer expands, melts and peels off when the enameled wire is exposed to high temperatures. This method is suitable for situations where only a small amount of enameled wire needs to be processed. First, cut a small section off the end of the enameled wire to be stripped with wire cutters. Then, heat the end of the enameled wire with a soldering iron. At high temperatures, the insulating varnish expands and softens, making it easy to peel off. Use tweezers, stripping pliers or a small flat-bladed screwdriver to carefully peel off the insulating varnish until the bare copper wire of the desired length is exposed.
Chemical stripping is another common method and is suitable for situations where a large amount of insulation needs to be removed. This method uses a chemical agent to quickly dissolve the insulation. First, soak the enameled wire to be stripped in the stripping agent. The stripping agent can be a commercial chemical stripping agent or a common household solvent such as acetic acid or alcohol. Ensure that the insulation varnish is in full contact with the stripping agent and soak for the time indicated by the stripping agent. The varnish will dissolve quickly when the stripper takes effect. Protect yourself with gloves and glasses, then gently wipe the enameled wire with a paper towel to remove the dissolved varnish.
