Scope

This part of GB/T 7672 specifies the requirements for temperature index 200, enamelled flat copper-clad wire with impregnated glass fiber and enamelled copper flat wire with grade 2 paint film thickness impregnated with enamelled glass fiber. The impregnating varnishes can be, for example, polyesterimide or silicone varnishes. Enameled wire shall be based on one of the following standards and shall be determined through consultation between the supplier and the purchaser: - GB/T 7095.4 Enamelled Flat Winding Wire Part 4: Grade 180 Polyesterimide Enamelled Copper Flat Wire; - GB/T 7095.6 Enamelled Copper Wire Flat winding wires - Part 6: Polyester or polyesterimide/polyamideimide composite enamelled copper flat wire, class 200. -IEC 60317-30 Standard for Special Winding Wires Part 30: Polyimide Enamelled Copper Flat Copper Wire Class 220. The enameled wire used should have a minimum thermal rating of 180. The temperature index of impregnated glass wire depends on the type of impregnating varnish used. The impregnating varnish which impregnates the glass filaments preferably has a temperature index of at least 200. There are four types of wrapping layer thickness: -GL1: single glass filament wrapping on bare conductor; -GL2: double glass filament wrapping on bare conductor; -Grade 2 GL1: single glass filament wrapping on enameled wire of grade 2 paint film thickness; -Grade 2 GL2: Double glass filament wrapped on a grade 2 film thickness enameled wire. The glass fiber cladding can be: a) single glass fiber wrapping; b) double glass fiber wrapping, the two layers of glass fiber wrapping are in opposite directions. The nominal size range of the conductor specified in this part is: - wide side size: minimum 2.00mm, maximum 16.00mm; - narrow side size: minimum 0.80mm, maximum 5.60mm. See GB/T 7672.1-2008 for the combination of wide side size and narrow side size and the ratio of wide side size and narrow side size.
