What is Copper Strip Winding?
Copper Strip Windings are composed of lacquered copper wires, which are the basic components of the circuit of every motor or equipment. Lacquered copper and aluminum wires offer advantageous space saving factors as well as high levels of breakdown voltages compared to fiber insulation. The main applications of enamelled copper wire and enamelled aluminium wire are winding of motors and transformers. The voltage of the winding wire depends on the thickness of the insulation layer and can have levels 1, 2 and 3. The higher the grade, the thicker the insulation layer and therefore the higher the breakdown voltage. The temperature rating indicates the temperature of the wire, which has a service life of 20,000 hours. Wires last longer at lower temperatures (about twice as long for every 10 °C drop in temperature). Common temperature classes are 105° C, 130° C, 155° C, 180° C, and 220° C.
What are the Advantages of Copper Strip Winding ?
Copper Strip Windings are widely used in electrical equipment due to their electrical conductivity. Aluminum and copper enameled wires are used to carry the current. In particular, lacquered copper electromagnetic wire has less resistance than almost any other insulated wire. This means that generators using lacquered copper wire will produce more electricity than generators using most other substances. Motor coils made of lacquered copper winding wire will produce more movement. Transformers made of enamelled copper wire windings will lose less energy. One of the main characteristics that makes it an ideal choice for a wide range of applications is the thin lacquer cladding insulation. Transformers, motors, and generators are all coil-based machines, which are devices that use large coils of wire to generate magnetic fields and currents. The smaller these devices are, the stronger they are. Because lacquered aluminum magnet wire and lacquered copper magnet wire are insulated by a thin layer of enamel, rather than other types of thicker insulating materials, such as paper, glass fiber, mica, etc. Since lacquered aluminum or copper wire takes up less space in coil formation, it can make more efficient and compact coils with higher efficiency.
How does Copper Strip Winding Deal with Works?
The enameled wire used in the copper Strip Windings also known as “electromagnetic wire”, is widely used in various electrical applications due to its excellent electrical, thermal and mechanical properties. Coated aluminum/coated copper wire is mainly used in three types of applications, where one type of electrical energy is converted into another type of electrical energy in a transformer. Coated aluminum/coated copper wire is insulated by coating it with different temperature grades. Polyethylene formaldehyde or A (PVF), polyurethane, polyamide (PUW), polyester (PEW), polyester polyimide (EIW), polyamide polyimide (or amide imide) (AI-EIW) and polyimide (AIW). Polyimide insulated electromagnetic wires are capable of operating at temperatures up to 250°C. These coatings are used to prevent short circuits on the surface of the wire when it is wound into a coil. Magnetic flux is produced when an electric current flows through the coil. Copper coated wire is mainly used in the manufacture of motors, electromagnets, transformers and inductors. To facilitate the manufacture of inductive components such as transformers and inductors, most of these wires can be welded. Copper coated wire is used in motors to convert electrical energy into mechanical energy. Aluminum-clad/copper-clad winding wires are also used in generators to convert mechanical energy into electrical energy.
