Polyester Enameled Copper Wire is a type of copper wire that has been insulated with a tough, durable polyester film.
This type of wire is designed to be used in applications that require high resistance to fire and extreme temperatures. This type of wire also has the ability to withstand certain chemicals and corrosive materials. There are many different types of this wire available and it is important to know what each one offers before making a purchase.
The insulation that is used to coat the copper wire in this type of wire varies and can be made from different materials. The most common material is fiberglass, but it can be made from polyurethane, plastic or rubber. The insulation used is also what determines the overall performance of the wire. The more durable the insulation, the better it will perform.
Some of the most common uses of this wire are in electric motors, solenoids and relays. It is also used in transformers, electrical power cords and audio inductors/chokes. This type of wire can also be used in various medical and laboratory applications. It is also used for wire wrapping in construction and the wiring of connections and components in electronics.
This wire is most often a fully annealed and electrolytically refined copper conductor, although aluminium magnet wire is sometimes used for large transformers and motors due to its lower cost. The copper is then surrounded by a thick layer of tough polyester, or sometimes by a more resilient glass-based vitreous enamel. This allows for closer winding when making electromagnetic coils, which increases current density. Modern high-temperature insulated magnet wire is usually made with one to four layers (quad-film type wires) of tough polymer film materials.
The temperature class of the insulation and the breakdown voltage of the copper depend on the thickness of the covering. Thicker coatings have higher breakdown voltages, and a wider range of temperature classes is available.
There are several different kinds of insulated copper wire, each with its own advantages and disadvantages. Bondable magnet wire has a superimposed film of thermoplastic bonding material which makes it possible to make coils with shapes that would not be possible with normal insulated copper wire. It also enables the ends of the coil to be soldered together without the need for stripping the insulation.
This type of insulated wire is used in high-temperature applications and can be found in industrial equipment, motors, transformers and other electronic devices. It is also a popular choice for use in electrical applications and in educational physics experiments to demonstrate the theory of electromagnetism. It is also commonly used for repairing and in hobby electronics. It is also very useful for constructing electromagnets. It is a good alternative to enamelled copper wire in situations where it is not necessary to achieve high levels of current density. It is also often used for wiring electrical circuits in schools and homes.
