適用范圍：This part of IEC 317 specifies the requirements of tape wrapped rectangular copper winding wire of class 240. The insulation 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 ℃.NOTE - In some countries, e.g.. Canada, Russia, USA, this product is assigned a class 220.The tape is coated on one or both sides 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 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:- width: min. 2,00 mm, max. 16,00 mm;- thickness: min. 0,80 mm, max. 5,60 mm.The specified combinations of width and thickness as well as the specified ratio width/thickness are 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 A2
