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.

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.
