High-voltage isolating switch, in particular a pantograph isolating switch

摘要

The high-voltage isolating switch has a pair of main contact rails (6), which are fitted to the ends of pantograph struts (4) and can move therewith, and a cable mating contact piece (2), which is attached to a high-voltage line. In order to improve the current transmission, by increasing the number of contact points between the cable contact and the pantograph struts, it is provided that the contact rails (6) have slots (8) running in the direction of their longitudinal axis. <IMAGE>
