Scope

This part of GB/T 7672 specifies the requirements for temperature index 155, enamelled flat copper-clad wire with impregnated glass filament and enamelled copper flat wire with grade 2 paint film thickness impregnated with impregnated glass filament. The impregnating varnish can be, for example, polyester or polyesterimide resin varnish. 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 7095.3 Enamelled Flat Winding Wire Part 3: Grade 155 Polyester Enamelled Copper Flat Wire; - GB/T 7095.4 Enameled Flat Winding Wire Part 4: Class 180 Polyesterimide Enamelled Copper Flat Wire; -GB/T 7095.6 Enamelled Flat Winding Wire Part 6: Class 200 Polyester or Polyesterimide/Polyamideimide Composite Enamelled Copper flat line. The enameled wire used should have a minimum thermal rating of 130. The temperature index of impregnated glass wire depends on the type of impregnating varnish used. The impregnating varnish impregnating the glass filaments preferably has a temperature index of at least 155. 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.
