POLYAMIDE LMIDE COVERED SELF BONDING MAGNET WIRE RECTANGULAR ENAMELED COPPER WIRE

Polyimide-covered wires are bare wires taped with different grades of polyimide/FEP tapes. Depending on the application conditions, corona discharge-resistant or waterproof types are available. The polyimide yields high-temperature resilience, class 240 complemented by a high breakdown voltage. The corona discharge-resistant version provides a much higher resistance to voltage peaks than the standard polyimide. For applications in high-humidity atmospheres a waterproof polyimide variant can be used. To give a higher mechanical strength to the wire a glass covering will be applied. A nickel plating on the copper conductor results in outstanding behavior for high temperatures and in radiation fields.
