A wire is a wire that transmits electrical energy. Divided into bare wire, magnet wire and insulated wire. Bare wire has no insulation layer, including copper, aluminum flat wire, overhead stranded wire and various profiles (such as profile wire, busbar, copper bar, aluminum bar, etc.). It is mainly used for outdoor overhead and indoor busbars and switch boxes. Magnet wire is an insulated wire that generates a magnetic field when energized or induces a current in the magnetic field. It is mainly used for motor and transformer winding and other related electromagnetic equipment. The conductor is mainly copper wire, which should have a thin insulating layer and good electrical and mechanical properties, as well as heat resistance, moisture resistance, solvent resistance and other properties. Different properties can be obtained by selecting different insulating materials. A wire is a wire that transmits electrical energy. Divided into bare wire, magnet wire and insulated wire.

Different properties can be obtained by selecting different insulating materials.There are two main types of magnet wire: enameled wire and wrapped wire. The enameled wire is made by coating the bare copper wire with insulating varnish. The insulating layer is thin and occupies a small volume. It is widely used in various electrical appliances and instruments. The properties of enameled wire vary with the nature of the insulating material used. Wrapped wires mainly include yarn-covered wires, silk-covered wires, glass-covered wires, paper-covered wires, and plastic film-covered wires. Among them, yarn-covered wires and silk-covered wires may be eliminated due to their poor temperature resistance and large footprint. The glass fiber covered wire is wrapped with glass fiber outside the round copper wire and impregnated with silicone resin. It can withstand high temperature of 180 ° and has good insulation performance and mechanical strength. Paper-covered wire is mainly used for oil-immersed transformers. The plastic film-covered wire is made of polyimide film coated with some kind of adhesive, and wrapped around the conductor and baked. Its insulating layer is tough and elastic, easy to wrap, wear-resistant and heat-resistant, and is widely used in space navigation and other equipment. The insulated wire is generally composed of a conductive wire core, an insulating layer and a protective layer. The wire core can be divided into four types: hard type, soft type, movable type and extra-soft type according to the requirements of use. There are four types of wire cores: single core, two cores, three cores and four cores. The insulating layer is generally made of rubber, plastic, etc. Such insulated wires are widely used in various instruments, telecommunication equipment, power lines and lighting lines with AC voltage below 500 volts and DC voltage below 1000 volts.
