Earthing and short-circuit terminal for overhead lines

摘要

The invention relates to an earthing and short-circuit terminal having a bracket, which is to be hung over the overhead line, with a contact surface, a screw spindle and a pressure piece which can be pressed against the line by the screw spindle. In order, in the short-circuit case, not to have too much distance between the terminal surfaces of the bracket and of the pressure piece, on the one hand, and the surface of the line cable on the other hand, it is provided that the contact surface (6) of the bracket has grooves (16) and teeth (17) in a relatively large number and with a relatively small depth or height of approximately 0.3 to 0.7 mm. Furthermore, electrical insulation is provided between the bracket (2, 3), especially its threaded hole, and the bearing surface (7) of the pressure piece (8). <IMAGE>
