This part of IEC 60317 specifies the
requirements of enamelled rectangular copper
winding wire of class 180 with a sole coating based
on polyesterimide resin, which may be modified
providing it retains the chemical identity of the
original resin and meets all specified wire
requirements.
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.
Class 180 is a thermal class that requires a
minimum temperature index of 180 and a heat
shock temperature of at least 200 °C.
The temperature in degrees Celsius corresponding
to the temperature index is not necessarily that at
which it is recommended that the wire be operated
and this will depend on many factors, including the
type of equipment involved.
The range of nominal conductor dimensions covered
by this standard is:
Wires of grade 1 and grade 2 are included in this
specification and apply to the complete range of
conductors.
The specified combinations of width and thickness
as well as the specified width/thickness ratio are
given in IEC 317-0-2.
— width: min. 2,0 mm max. 16,0 mm;
— thickness: min. 0,80 mm max. 5,60 mm.
