National foreword

This British Standard has been prepared by Technical Committee GEL/55 (formerly CIL/55) and is the English language version of EN 60317-7

Specification for particular types of winding wires — Part 7: Polyimide enamelled round copper wire, class 220, including amendments A1:1997 and A2:1998,

published by the European Committee for Electrotechnical Standardization (CENELEC) It is identical with IEC 60317-7:1990, including amendment 1:1997 and amendment 2:1997, published by the International Electrotechnical

Commission (IEC)

The introduction to IEC 60317-7 reads as follows

“This International Standard is one of a series which deals with insulated wires used for windings in electrical equipment The series has three groups describing: 1) methods of test (IEC 851);

2) specifications (IEC 317);

3) packaging (IEC 264).”

NOTE 1 Reference should be made to BS 6811-0 General introduction and list of Parts.

A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application

Compliance with a British Standard does not of itself confer immunity from legal obligations.

1 Scope

This International Standard specifies the requirements of enamelled round copper winding wire of class 220 with a sole coating based on polyimide resin

Class 220 is a thermal class that requires a minimum temperature index of 220 and a heat shock temperature of at least 240 °C

The temperature in degrees Celsius corresponding

to the temperature index is not necessarily that at which it is recommended that the wire be operated and this will depend on many factors, including the type of equipment involved

The range of nominal conductor diameters covered

by this standard is:

— Grade 1: 0,020 mm up to and including 2,000 mm;

— Grade 2: 0,020 mm up to and including 5,000 mm

The nominal conductor diameters are specified in

clause 4 of IEC 317-0-1.

2 Normative references

The following standard contains provisions which, through reference in this text, constitute provisions

of this International Standard At the time of publication, the edition indicated was valid All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent edition of the standard indicated below Members of IEC and ISO maintain registers of currently valid International Standards

The dielectric dissipation factor tan $ shall not

exceed 60 × 10–4 at a frequency of 1 000 Hz

NOTE 1 Test under consideration.

NOTE 2 In case the dielectric dissipation factor tan $ cannot

be measured, this measurement shall be replaced by a

measurement of the loss of mass.

20 Resistance to transformer oil

Test appropriate but no requirements specified

21 Loss of mass

Test inappropriate, but requirements shall be agreed between purchaser and supplier
