Scope

This part of GB/T 7672 specifies the requirements for temperature index 130, enamelled flat copper-clad wire with impregnated glass fiber and enamelled copper flat wire with grade 2 paint film thickness impregnated glass fiber. Wherein the impregnating varnish can be, for example, polyester resin varnish. The enameled wire shall be based on the following standards and shall be determined through consultation between the supplier and the purchaser: ——GB/T 7095.7 Enamelled flat winding wire Part 7: Class 130 polyester enamelled flat copper wire. 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 dipping varnish for impregnating glass wool has a temperature index of at least 130. The thickness of the wrapping layer is divided into three types: —— GL2: wrapping double glass filaments on the bare conductor; ——Grade 2 GL1: wrapping single glass filaments on enameled wires with 2-grade paint film thickness; The film thickness enameled wire is covered with double glass filaments. 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.
