Wire enamels are applied on copper and aluminum round and flat wires used in motors, transformers, generators and electrical measuring instruments.
They are cured onto the wires with heat. The resulting coating’s main function is electrical insulation. Wire enamels are also described as primary insulation.
The coated wires are sometimes called “magnet wires”. Wires insulated by wire enamels Wire enamels are applied to copper and aluminum wires in up to 30 layers.
This provides electrical insulation and helps the windings from short-circuiting. These wire enamels must also have very good chemical and thermal resistance, must adhere very well to copper or aluminum wire, and have outstanding mechanical stability.
In some instances, for example when used in inverter-driven electric motors, the appropriate insulation layer should resist.
The wires that are coated vary greatly depending on their use. Some may be smaller than the diameter of a single human hair – in electronic components of watches for instance.
But in heavy electric motors in wind generators, the diameter of round or flat wires can measure up to several millimeters.
The wire enamel is applied differently depending on the shape and diameter of the wire to be coated. Horizontal or vertical application, or application with dies or with felts, are typical wire coating methods.
The Europe wire enamels market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Elektrisola specializes in fine enamelled wire diameters, starting with 0.008 mm (8 microns), and going up to a diameter of 0.50 mm.
Beside the standardized diameters a big variety of special diameters is produced according to customer’s specification.
Bare wire tolerances are very important in enamelled wire as they have a direct impact on the resistance what again determines the variance of the final coil resistance.
Enamelled wire is a metallic conductor insulated with a varnish and generally used for electrical applications. Most times enamelled wire is wound in different shapes of coils to generate magnetic force for motors, transformers, magnets etc. Elektrisola produces over 30,000 different types of enamelled wire.
