Enameled Wire Thermal Class Guide
Enameled wire thermal class describes the temperature rating of the insulation system and helps engineers select winding wire for motors, transformers and coils.
Enameled Wire Insulation Types
Enameled wire insulation types include polyurethane, polyester, polyester-imide, polyamide-imide, polyimide and overcoat systems selected by temperature, solderability and application.
Polyamide-Imide Enamel Insulation
Polyamide-imide enamel insulation is used for high-performance magnet wire where heat resistance, abrasion resistance, overload margin and winding durability are important.
Polyimide Enamel Insulation
Polyimide enamel insulation is selected for special high-temperature magnet wire applications that need strong heat resistance, dielectric performance and material stability.
Nylon Overcoat for Enameled Wire
Nylon overcoat is used on enameled wire to improve surface toughness, abrasion resistance, winding performance and production handling.
Corona-Resistant Enamel Insulation
Corona-resistant enamel insulation is used for magnet wire exposed to partial discharge stress, inverter-fed motors, EV motors and high-voltage pulse conditions.
Polyurethane Enamel Insulation
Polyurethane enamel insulation is widely used for solderable magnet wire in small coils, relays, transformers and electronics where fast termination is important.
