<p>This device is of the type comprising a set of busbars 2 intended for providing the conduction of the electrical current, isolators 3 fitted on either side of the bars 2 and transverse supports 14 disposed on either side of the set of bars, carrying the isolators 3 and maintaining the spacing between the bars. According to the invention, each of the transverse supports 14 has, at the position of each of its zones 21 for cooperating with at least one isolator 3, a longitudinal metallic reinforcement part 22 of U-shaped transverse cross-section, the flanges 22a of which, on the one hand, engage with the lateral walls of at least one isolator 3, and, on the other hand, are bear by their ends against the U-shaped cut-out edges 14b provided in the flanges of the support 14 while its web is immobilised with respect to translational movement in relation to this support 14. <IMAGE></p> |
