IEC 60317-48 (2012-07)

IEC 60317-48:2012 specifies requirements of glass-fibre wound resin or varnish impregnated, bare, grade 1 or grade 2 enamelled round copper winding wire, temperature index 155. 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:
- new subclause containing general notes on winding wire,
- formerly part of the scope,
- new subclause containing requirements for appearance,
- new Clause 23, Pin hole test. Keywords: copper winding wire
