IS 13730 : Part 15 : 1994 Particular types of winding wires : Part 15 Polyesterimide enamelled round aluminium wire, Class 180

1 Scope

This standard specifies the requirements of enamelled roundaluminium winding wire of Class 180 with a sole coating based onpolyesterimide resin, which may be modified, provided it retainsthe chemical identity of the original resin and meets all specifiedwire requirements.

Note - A modified resin is a resin that has undergone a chemicalchange, or contains one or more additives to enhance certainperformance or application characteristics.

Class 180 is a thermal class that requires a minimum temperatureindex of 180 and a heat shock temperature of atleast 200 �C.

The temperature in degrees celsius corresponding to thetemperature index is not necessarily that at which it isrecommended that the wire be operated and this will depend on manyfactors, including the type of equipment involved.

The range of nominal conductor diameters covered by thisstandard is:

- Grade 1 : 0.250 mm up to and including 2.500 mm

- Grade 2 : 0.250 mm up to and including 2.500 mm

The nominal conductor diameters are specified in 4 of IS 13730 :Part 0 : Sec 3 : 1994.
