NATIONAL FOREWORD

This Indian Standard (Part 50) which is identical with IEC 60317-50 (1 999) ‘Specifications for particulartypes of winding wires — Part 50: Glass-fibre wound resin or varnish impregnated, bare or enamelledround copper wire, temperature index 200’ issued by the International Electrotechnical Commission (l EC)was adopted by the Bureau of Indian Standards on the recommendations of the Winding Wires SectionalCommittee (ET 33) and approval of the Electrotechnical Division Council.

The text of the IEC Standard has been approved as suitable for publication as an Indian Standard withoutdeviations. Certain conventions are, however, not identical to those used in Indian Standards. Attentionis particularly drawn to the following:

a) Wherever the words ‘International Standard’ appear, referring to this standard, they should be readas ‘Indian Standard’.

b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practiceis to use a point (.) as the decimal marker.

Only the English text of the International Standard has been retained while adopting it as an IndianStandard and as such the page numbers given here are not the same as in IEC Publication.

In this adopted standard, reference appears to the following International Standard for which IndianStandard also exists. The corresponding Indian Standard which is 10 be substituted in its place is listedbelow along with its degree of equivalence for the edition indicated:

For the purpose of deciding whether a particular requirement of this standard is complied with, the finalvalue, observed or calculated expressing the result of a test, shall be rounded off in accordance withIS 2:1960 ‘Rules for rounding off numerical values (revised)’. The number of significant places retainedin the rounded off value should be the same as that of the specified value in this standard.

PART 50 GLASS-FIBRE WOUND RESIN OR VARNISH-IMPREGNATED, BARE OR

ENAMELLED ROUND COPPER WIRE, TEMPERATURE INDEX 200

1 Scope

This part of IEC 60317 specifies the requirements of glass-fibre wound resin or varnishimpregnated, bare, grade 1 or grade .2 enamel led round copper winding wire, temperatureindex 200. The impregnating agent can be, for instance, polyesterimide or silicone resin based.

NOTE For this type of wire, the heat shock test is inappropriate and therefore a heat shock temperature cannot beestablished. Consequently, a class based on the requirements for temperature index and heat shock temperaturecannot be specified.

The enamelled wire should be based on one of the following standards and should be agreedbetween purchaser and supplier: IEC 60317-13 or IEC 60317-46.

The temperature index of the wire is dependent upon the type of impregnating agent used. Theimpregnating agent applied to the glass fibre should have a minimum temperature index of 200.

The glass-fibre covering may be

a) a single layer of glass fibre;

b) a double layer of glass fibre, with one layer applied in the direction opposite to that of theother layer.

The range of nominal conductor diameters covered by this standard is

– for bare covered wires (grade G2): 0,500 mm up to and including 5,000 mm;

– for grade 1 enamelled wires (grades 1G1 and 1G2): 0,500 mm up to and including 1,600 mm;

– for grade 2 enamelled wires (grades 2G1 and 2G2): 0,500 mm up to and including 5,000 mm.

The nominal conductor diameters are specified in clause 4 of the future IEC 60317-0-6.

2 Normative references
