Specifications for particular types of winding wires - Part 13: Polyester(imide) overcoated with polyamide-imide, enamelled round copper winding wire, class 200 HD 555.13 S1:1990

Scope

This International Standard specifies the requirements of enamelled round copper winding wire of class 200 with a dual coating - The underlying coating is base 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 (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 200 is a thermal class that requires a minimum temperature index of 200 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 diameters covered by this standard is: Grade 1) 0,050 mm up to and including 2,000 mm - Grade 2) 0,050 mm up to and including 5,000 mm - The nominal conductor diameters are specified in clause 4 of IEC 317-0-1
