The series has three groups describing: 1) Winding wires Test methods (IEC 60851); 2) Specifications for particular type

26、s of winding wires (IEC 60317); 3) Packaging of winding wires (IEC 60264). BS EN 60317-21:2014 EN 60317-21:2014 6 60317-21 IEC:2013 SPECIFICATIONS FOR PARTICULAR TYPES OF WINDING WIRES Part 21: Solderable polyurethane enamelled round copper wire overcoated with polyamide, class 155 1 Scope This part

27、 of IEC 60317 specifies the requirements of solderable enamelled round copper winding wire of class 155 with a dual coating. The underlying coating is based on polyurethane resin, which may be modified providing it retains the chemical identity of the original resin and meets all specified wire requ

28、irements. The superimposed coating is based on polyamide resin. NOTE A modified resin is a resin that has undergone a chemical change, or contains one or more additives to enhance certain performance or application characteristics. The range of nominal conductor diameters covered by this standard is

29、: Grade 1: 0,050 mm up to and including 1,600 mm; Grade 2: 0,050 mm up to and including 1,600 mm. The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-1:2013. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are

30、indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

In case of inconsistencies between IEC 60317-0-1:2013 and this p

32、art of IEC 60317, the latter shall prevail. 3.2.2 Winding wire Class 155 is a thermal class that requires a minimum temperature index of 155 and a heat shock temperature of at least 175 C. The temperature in C corresponding to the temperature index is not necessarily that at which it is recommended

33、that the wire be operated and this will depend on many factors, including the type of equipment involved.
