IEC 60317-1:2010 pdf free download Specifications for particular types of winding wires – Part 1: Polyvinyl acetal enamelled round copper wire, class 105
1 scope
This Part of lEC 60317 specifies the general requirements of enamelled round copper windingwires of class 105 with a sole coating based on polyvinyl acetal resin,which may be modifiedproviding it retains the chemical identity of the original resin and meets all specified wirerequirements.
NOTE A modified resin is a resin that has undergone a chemical change,or contains one or more additives toenhance certain performance or application characteristics.
Class 105 is a thermal class that requires a minimum temperature index of 105 and a heatshock temperature of at least 155°C.
The temperature in degrees Celsius corresponding to the temperature index is not necessarilythat at which it is recommended that the wire be operated and this will depend on manyfactors, including the type of equipment involved.
The range of nominal conductor diameters covered by this standard is as follows:- Grade 1: 0,040 mm up to and including 2,500 mm;
-Grade 2: 0,040 mm up to and including 5,000 mm;- Grade 3: 0,080 mm up to and including 5,000 mm.
The nominal conductor diameters are specified in Clause 4 of lEC 60317-O-1.
