IS 6162 : Part 2 : 1971 : Paper Covered Aluminium Conductors - Part II : Rectangular Conductors

1. SCOPE

1.1 General — This standard (Par t I I ) gives requirements and tests for solid aluminium conductors of rectangular section, covered with two or more layers of paper, primarily intended for transformer windings.

1.2 Sizes — The requirements of the standard are applicable to conductors having thicknesses from 0.80 up to and including 5.6 mm and widths from 2 up to and including 16 mm. A schedule of preferred sizes is given in IS : 6160 - 1971*.

1.3 Grades of Covering — Two grades of covering are specified:

a) Double Paper Covered — with a minimum total increasc in dimensions of 0.25 mm due to covering; and

b) Multiple Paper Covered — with more than two layers of paper.

NOTE - Edgewise bending paper-covered conductors conforming to this standard are not necessarily suitable for severe edgewise bending. Any special test requirements should be agreed between the manufacturer and the purchaser.
