Specifications for particular types of winding wires - Part 50: Glass-fibre wound silicone resin or varnish impregnated, bare or enamelled round copper wire, temperature index 200

Publication date:   Dec 18, 2012

Scope

IEC 60317-50:2012 specifies the requirements of glass-fibre wound resin or varnish impregnated, bare, grade 1 or grade 2 enamelled round copper winding wire, temperature index 200. The impregnating agent is silicone 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.
