<p>The bars to carry the current are of thick channel section, with the edges (6, 7) of the channels (3, 4) spaced apart by a distance (d). Each of the two thick channel sections have four circular cooling channels (5) at the corners and the edges of the channels. There are two deep interlocking 'U' sections (8) fastened to the bases of the thick channel sections, and the whole system has rotational symmetry. The distance between the ends of the deep channels and the bottoms (9) of the channel is (d), and the side walls of the channels are the same distance apart.</p> |
