BS EN 60317-25:2010 Specifications for particular types of winding wires - Polyester or polyesterimide overcoated with polyamide-imide enamelled round aluminium wire, class 200
This Part of IEC 60317 specifies the requirements of enamelled round aluminium winding
wires of class 200 with a dual coating. The underlying coating is based on polyester or
polyesterimide resin, which may be modified providing it retains the chemical identity of the
original resin and meets all specified wire requirements. The superimposed coating is based
on polyamide-imide resin.
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 standard is as follows:
– Grade 1: 0,400 mm up to and including 3,150 mm;
– Grade 2: 0,400 mm up to and including 5,000 mm.
The nominal conductor diameters are specified in Clause 4 of IEC 60317-0-3.
