Detail of GB/T 7672.1-2008

Introduction of GB/T 7672.1-2008

1 Scope This part of GB/T 7672 specifies general requirements of glass-fiber wound resin or varnish glass-fiber wound resin or varnish impregnated bare or enamelled rectangular copper wire. The range of nominal conductor dimensions is given in the relevant product standard (see Annex C for product model and designation). When reference is made to a glass-fiber winding wire according to a standard of the GB/T 7672.3, GB/T 7672.4 and GB/T 7672.5 mentioned under Clause 2, the following information shall be given: ——reference to GB and/or IEC specification; ——nominal conductor dimensions (width × thickness), mm; ——thickness grade of coating and glass-fiber cladding. Example: GB/T 7672.4-2008 1.00×4.00, Grade 2 GL1 or IEC 60317-31 4.00×1.00 Grade 2 GL1 2 Normative references The following standards contain provisions which, through reference in this part of GB/T 7672, constitute provisions of this part. For dated references, subsequent amendments (excluding corrections) to, or revisions, of any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest editions apply.
