Device with two rigid busbars and a section insulator

The section insulator for rigid busbars has a conductive skid, a ramp, and an insulating skid connected to each busbar. The conductive skid (7, 7') and the ramp (11, 11') are connected to each other at one end (10) and to the busbar at the other end, the latter ends being offset relative to one another in the longitudinal direction (3). The two busbars (1, 2) are connected to each other in a torsionally rigid manner by means of profiled insulating sections (5, 6). Insulating skids (14, 14') are attached to the profiled insulating sections opposite the respective conductive skids such that a current collector is correctly guided when moved by. An insulating distance is provided between the ends of the conductive skids (7, 7') and the ends of the closest insulating skid (14, 14').
