Section insulator for an overhead contact line arranged for being placed between two isolated sections of said overhead contact line, said section insulator having an insulating element placed between two contact wires of two adjacent sections of an overhead line; two clamps respectively connected on one side to a respective contact wire and on the other side to a connecting plate arranged for being in turn connected to the insulating element, so that the tensile force due to the contact wires applies along the axis of the insulating bar; and supporting means directly connected to the insulating element through the connecting plates and arranged for supporting the section insulator to the overhead line.

A section disconnect device for a contact line assigned in particular to railborne vehicles as overhead line and carrying high voltage, having a single section arrangement (10) with multiple line sections extending, such that it is tensioned or can be tensioned, between two contact-wire connecting heads (12, 14) and provided with insulator means (36, 38), which line section arrangement is constructed such that it can be mounted by means of respective accommodating sections (66) of the contact-wire connecting heads in an electrically and mechanically contacting manner between exposed ends (16, 18) of the contact line, as a result of which at least one of the contact-wire connecting heads (12, 14) has adjustable level equalization means (66, 68, 70) for interacting with a head-side end (20, 24) of the line section arrangement (10), which are constructed in such a manner that, with respect to a current collector contact, in particular a current-collector-contact side of the contact line and/or a current-collector-contact plane, the free end of the contact line can be brought into a common plane with the end of the line section arrangement and/or seamlessly aligned with the same.

An insulating track segment for a ground power supply system includes a body made of an electric current insulating material. The insulating track segment constitutes a portion of an insulating track for forming a continuous sliding surface for a pad of a vehicle powered by the ground power supply system.

A residual load circuit breaker (1) includes a rotary switch body (23), which includes a contact blade (24, 25, 26, 27), that is rotatable about an axis (A) and is arranged between a feed line connection (20) and a discharge line connection (21), and includes end-side contact surfaces (28, 29, 30, 31) protruding in a radial direction. The contact surfaces, in a closed rotary position (S1) of the rotary switch body (23), are in touching contact with the feed line connection (20) and with the discharge line connection (21). In an open rotary position (S2) of the rotary switch body (23), the contact surfaces are each spaced with respect to the feed line connection (20) and with the discharge line connection (21). The residual load isolating switch (1) is rotationally limited in one rotational direction for performing switching movements and can be actuated unidirectionally and cyclically.

An electrified road transport system includes a contact line system having a plurality of masts with support cables and contact wires suspended thereon. The contact line system has structural modifications for reducing the horizontal and/or vertical positional tolerances of the contact wires. In the context of the structural modifications, section separators are fastened directly to masts or to cantilevers of the masts, skewed overhead lines are disposed in straight section segments and/or in curves, and the support cables and/or contact wires have smaller cross-sections and/or higher longitudinal tensile forces. A method for stabilizing a contact line system of an electrified road transport system is also provided.
