IEC 60317-54 pdf download Specifications for particular types of winding wires – Part 54: Polyester enamelled round copper wire, class 1 55L
1Scope
This part of lEC 60317 specifies the requirements of enamelled round copper winding wire ofclass 155L with a sole coating based on polyester resin，which may be modified providing itretains the chemical identity of the original resin and meets all specified wire requirements.NOTE 1 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 155L is a thermal class that requires a minimum temperature index of 155 and a heatshock temperature of at least 175 °C.
NOTE 2 This type of enamelled wire has lower heat shock performance compared to polyester enamelled roundcopper wire class 155 according to lEC60317-3.
The temperature in degrees Celsius corresponding to the temperature index is not necessarilythat at which it is recommended that the wire be operated; this will depend on many factors,including the type of equipment involved.
The range of nominal conductor diameters covered by this part of lEC 60317 is as follows:- grade 1 : 0,050 mm up to and including 3,150 mm;
-grade 2: 0,050 mm up to and including 5,000 mm.
The nominal conductor diameters are specified in clause 4 of lEC 60317-O-1.
