22、 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).1 ScopeThis part of IEC 317 specifies the requirements of tape wrapped rectangular copper winding wire of class 240. The insulation
23、 consists of one or two wrappings of aromatic polyimide tape.Class 240 is a thermal class that requires a temperature index of 240 and a heat shock temperature of at least 260 C.NOTE In some countries, e.g. Canada, Russia, USA, this product is assigned a class 220.The tape is coated on one or both s
24、ides with a suitable adhesive, for instance, fluorinated ethylene propylene. After wrapping, the tape is heat-sealed to form a continuous and adherent sheath.Specific requirements may be subject to contract.The temperature in degrees Celsius corresponding to the temperature index is not necessarily
25、that at which the wire is recommended to be used and this will depend on many factors, including the types of equipment involved.The range of nominal conductor dimensions covered by this standard is: The specified combinations of width and thickness as well as the specified ratio width/thickness are
26、 given in IEC 317-0-2.When a reference is made to winding wire according to this standard, the following information should be given:reference to IEC 60317-44;dimension of the nominal conductor (width thickness);grade.Example: 60317-44 IEC 4,00 mm 1,00 mm grade A22 Normative referencesThe following
27、normative documents contain provisions which, through reference in this text, constitute provisions of this part of IEC 317. At the time of publication, the editions indicated were valid. All normative documents are subject to revision, and parties to agreements based on this part of IEC 317 are enc

34、mbers of IEC 851.In case of inconsistencies between IEC 851 on methods of test and this part of IEC 317, the latter shall prevail.Where no specific range of nominal conductor dimensions is given for a test, the test applies to all nominal conductor dimensions covered by the specification sheet.Unles
35、s otherwise specified, all tests shall be carried out at a temperature from 15 C to 35 C and a relative humidity from 45 % to 75 %. Before measurements are made, the specimens shall be preconditioned under these atmospheric conditions for a time sufficient to allow the specimens to reach stability.T
36、he wire to be tested shall be removed from the packaging in such a way that the wire will not be subjected to tension or unnecessary bends. Before each test, sufficient wire should be discarded to ensure that any damaged wire is not included in the test specimens.4 DimensionsThe dimensions due to th

The dimensions in this standard shall be used as a guide in forming that agreement.4.1 Conductor dimensionsSee 4.1 of IEC 317-0-2.4.2 Tolerance on conductor dimensionsSee 4.2 of IEC 317-0-2.4.3 Rounding of cornersSee 4.3 of IEC 31
