The invention discloses a 200-level anti-pulse voltage composite enameled wire which comprises round copper wires (2). The surfaces of the round copper wires (2) are provided with a variable frequency paint layer (3) and a polyamide imide paint layer (1) in sequence from inside to outside, wherein the variable frequency paint layer (3) includes eight polyester imide paint layers, and the thickness of each polyester imide paint layer is 0.005 [mu]m. The 200-level anti-pulse voltage composite enameled wire in the invention has good corona-resistant performance, thereby prolonging the service life of a variable frequency motor.
