IEC 60317-70-1:2020 ED1

Specifications for particular types of winding wires - Part 70-1: Polyester glass-fibre wound unvarnished and fused, bare or enamelled round copper wire, temperature index 155 IEC 60317-70-1:2020 ED1

Publication date:   Jun 22, 2020

Scope

IEC 60317-70-1:2020 specifies the requirements of polyester glass-fibre wound unvarnished and fused bare, grade 1 or grade 2 enamelled round copper winding wires, temperature index 155. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-10:2017.
NOTE 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.
