IEC 60317-49:2012 specifies the requirements of glass-fibre wound resin or varnish impregnated, bare, grade 1 or grade 2 enamelled round copper winding wire, temperature index 180. The impregnating agent can be, for instance, polyester or polyesterimide resin based. For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot be established. Consequently, a class based on the requirements for temperature index and heat shock temperature cannot be specified. This edition includes the following significant technical changes with respect to the previous edition:
- addition of requirements for appearance, new subclause 3.3 and
- addition of pin hole test requirements, Clause 23, Pin hole test. Keywords: copper winding wire
