ABSTRACT:
A section insulator for trolley wires of electric railways is disclosed. The ends of two trolley wires are fastened to two insulating sliding strips between which arcing horns are arranged. The insulating sliding strips comprise a fiber-reinforced plastic wherein the filament fibers of the fiber reinforcement are stacked parallel to each other and are arranged perpendicularly to the sliding surface. The arcing horns are approximately U-shaped with the legs of the U-shape forming a leading runner and an adjusting loop bridged by an approximately V-shaped cross-piece. The arcing horns are disposed with the arc guiding parts facing each other and lying above the two insulating sliding strips in their operating position. Depressions are provided in the sliding surface of the insulating sliding strips to reduce accumulation of deposits.
