Enameled wire is a wire coated with a thin layer of insulation to prevent the wire surfaces from being in a short circuit when wound into coils. Magnetic flux is created when current flows through the coil. It is used mainly in the construction of motors, electromagnets, transformers and inductors. For ease of manufacturing inductive components like transformers and inductors, most of these wires can be soldered. Enameled wires are classified by their diameter (AWG gauge number or millimetres), temperature class and insulation thickness. A thicker insulation layer results in a higher breakdown voltage (BDV). Common temperature classes are 130, 155, 180 and 200 °C. Colored Enamel Foral Wire Feature: The inner steel core has firm enamel coating. Fire resisting. Firm color. Environmental friend. Sizes: 0.3mm-1.6mm. Colors available: Grass green, dark green, white, blue, red, etc.
