This part of JB/T 6758 specifies the general requirements for heat-resistant enameled transposed conductors. Such as polyester fiber non-woven tape insulated 155-grade modified polyester enameled transposed wires and semi-rigid wires (referred to as non-woven transposed wires); aromatic polyamide paper insulated with 180-grade polyesterimide or 200-grade polyester Esterimide/polyamideimide composite enameled transposed wires and semi-rigid wires (referred to as aromatic polyamide paper transposed wires), etc. The copper conductor of enamelled copper flat wire can be either ordinary soft copper wire or semi-hard copper wire. This section should be used in conjunction with JB/T 6758.1.
