Lacquered wire enamel can be applied to up to 30 layers of copper and aluminum wire. This provides electrical insulation and helps to short-circuit the windings. These enameled wire paints must also have very good chemical and heat resistance, must adhere well to copper or aluminum wire, and have excellent mechanical stability. In some cases, such as when used in inverter-driven motors, the appropriate insulation should be resistant to possible partial discharge, which may lead to short circuit and failure of the motor. The importance of the use of polyamide-imide enamel as a paint wrap is highlighted here.

Polyester glass fiber cloth is a common textile covering, wrapped with conductor wires in a heat-treated combination.

Kapton enamel is designed for covering enameled wire and various electric heating applications. This insulating film can be laminated, metallized, punched, molded or bonded to coating Kapton is classified as thermoplastic and thermosetting plastics. Kapton polymers are responsible for polyimide thermal stability, good chemical inertness and excellent strength and stiffness. This insulating film has a unique combination of properties and is ideally suited for a variety of applications in many different industries.

Bondable Enamel is a kind of composite material that allows inorganic glassy material to be fused onto the substrate metal and firmly bound to the metal. The lead is aluminum or copper wire. Wires contain an additional adhesive film on top of the usual insulation layer, which activates when heated, resulting in what is called a bonding wire. It comes in different types, depending on the ingredients used, such as polyamides, imides, and polyester imides. It is used to protect tight coils manufactured in applications such as inductors, transformers, motors, loudspeakers, hard disk head actuators or enameled wires.

Polyesterimide PEI Enamel is an inorganic coating of enameled wire, which is mostly sprayed on the surface as precious metal and aluminum wires during hot machining. It is a reliable non-metallic inorganic coating oil paint with excellent thermal properties, both single and double coating applications, with thermal shock values between 3 and 5mm. thermal index level 180 or above.

A magnet coil is a conducting device that performs electrical work by applying electricity to a wire outside a magnet, converting electricity and magnetic forces into mechanical energy. The components of the electromagnet coil are the absorption coil (enameled wire group) and the magnetic force system (magnet). The magnetic system consists of an iron core, a yoke and an armature. A simple conduction structure is housed in a cylindrical housing to perform various electrical tasks. Screw, direct, E, and U are all common forms, but they all have a similar principle. When the coil is energized, the magnetic force will be generated. The inflow end of the magnetic force is the S pole, and the output end is the N pole. Opposite poles will be created at the ends of the magnet, and an attractive force will be created between the core and the armature.

Kraft paper, usually yellowish-brown, is made of kraft conifer pulp, soaked in water and beaten on a mesh paper machine. It can be used as cement bag paper, envelope paper, glue sealing paper, asphalt paper, wire protection paper, insulating paper and so on. High temperature kraft paper is a tough water resistant packaging paper with low density and high physical strength, which can provide protection for enameled wire. Its working environment is usually 190-220 high temperature and 2.5MPa pressure. Oily kraft paper will produce hydrophobicity, can make enameled wire from damp and other risks, prolong the service life of wire.

Enameled copper clad aluminum wire has excellent high temperature resistance, mechanical properties, electrical properties, chemical properties and excellent freezing resistance. It is suitable for refrigerating equipment working at 200℃ for a long time, electrical equipment subject to chemical erosion, dry type transformer, oil-immersed transformer, epoxy casting transformer, iron remoter, electromagnet and other mechanical and electrical equipment.

According to low temperature resistance level (105°C, 120°C), Polyvinyl Acetal/Formal Enamel wire is widely used in oil-immersed transformers due to its excellent high temperature hydrolysis resistance, especially the acetal enameled flat wire is used to make continuously transposed conductors, used in large transformers.

NOMEX Paper or dupont nomex paper used as insulation materials, also called nomex insulation paper. In the electrical wire, enameled wire is covered with nomex paper widely used for transformer.

Pure copper is widely used in electrical, light industry, machinery manufacturing, construction industry, national defense industry and other fields, and is second only to aluminum in the consumption of non-ferrous metal materials in China.
