1 Scope

This standard (Part 9) specifies the requirements of enamelledround aluminium winding wire of Class 130 with a sole coating basedon polyester resin, which may be modified, provided it retains thechemical 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 130 is a thermal class that requires a minimum temperatureindex of 130 and a heat shock temperature of at least 155�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.
