A section insulator for two aligned rigid conductor rails, wherein the section insulator forms a closed system in that, in the extension of each conductor rail, a conductive runner and an insulating runner rigidly connected to the conductive runner are connected to the opposing conductor rail. The lower side of the runners, facing the travel plane, is arranged in a contact plane. All of the runners are also height-adjustable in relation to the conductor rails.

Section insulator

A conductor rail fishplate for the electrical and mechanical connection of successive conductor rails has two symmetrical plates, which encompass the exterior of the conductor rail. The two plates are tensioned against one another using screws. Contact strips are arranged in the contact zone between the conductor rail and the respective plates, the strips coming into contact with the respective surfaces by means of a large number of spring-loaded contacts.
