Specifications for particular types of winding wires -- Polyester glass-fibre wound unvarnished and fused or resin/varnish impregnated, bare of enamelled round copper wire temperature index 200
This part of IEC 60317 specifies requirements of polyester glass-fibre wound fused, silicone resin or varnish impregnated bare, grade 1 or grade 2 enamelled round copper winding wire, temperature index 200.
The impregnating agent is a silicone containing resin or varnish.
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.
