Wide range of wire applications, insulation performance

Wires are wires that transmit electrical energy. It is divided into bare wire, magnet wire and insulated wire. Bare wires have no insulation layer, including copper, aluminum flat wires, overhead stranded wires, and various profiles (such as molded wires, bus bars, copper bars, aluminum bars, etc.). It is mainly used for outdoor overhead and indoor busbars and switch boxes.

Magnet wire is a wire that has insulation and is capable of creating a magnetic field or inducing current within a magnetic field upon activation. It is primarily used in the winding of motors, transformers, and other electromagnetic equipment. The wire is typically made of copper material, which should possess excellent electrical and mechanical properties, with a thin layer of insulation. It must also have resistance to moisture, heat, and solvents while utilizing different insulating materials to achieve specific attributes.

Magnet wire is available in two main types: enameled wire and wrapped wire. Enameled wire comprises a bare copper wire coated with insulating varnish. Its insulating layer is thin and compact, making it ideal for use in different types of electrical appliances and instruments. Moreover, its performance varies depending on the insulating material used. Wrapped wires include yarn covered wire, silk covered wire, glass fiber covered wire, paper covered wire, and plastic film covered wire. However, yarn and silk covered wires are no longer utilized due to their poor temperature resistance and large occupied volume. Glass fiber covered wire is coated with silicone resin, making it capable of withstanding high temperatures of up to 180°C whilst boasting good insulation properties and mechanical strength. The paper covered wire is usually used in oil-immersed transformers; the plastic film covered wire, on the other hand, consists of polyimide film that has been baked onto a conductor with a certain adhesive and is highly flexible and resistant to wear and heat. Insulated wires are constructed from a conductive core, an insulating layer, and a protective layer. The core can either be hard, soft, mobile, or extra soft, depending on its required application. There are four core configurations: single core, two core, three core, and four core. The insulating layer, which is typically made of plastic, rubber, or other materials, offers a degree of protection for the wire. Insulated wires are used for power lines, lighting lines, telecommunications equipment, and different types of instruments and meters, and are suited to AC voltages below 500 volts and DC voltages below 1000 volts.
