This part of IEC 317 specifies the requirements of
enamelled round copper winding wire of class 200
with a sole coating based on polyester-amide-imide
resin, which may be modified providing it retains
the chemical identity of the original resin and meets
all specified wire requirements.
Class 200 is a thermal class that requires a
minimum temperature index of 200 and a heat
shock temperature of at least 220 °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 diameters covered
by this part is:
— Grade 1: 0,018 mm up to and
including 1,600 mm;
— Grade 2: 0,025 mm up to and
including 5,000 mm.
The nominal conductor diameters are specified in
clause 4 of IEC 317-0-1.
