Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An insulating track segment for a ground power supply system, comprising a body made of an electrical insulating material, wherein the insulating track segment constitutes a portion of an insulating track for forming, with a conductive track of the ground power supply system, a continuous sliding surface for a pad of a vehicle powered by the ground power supply system, the body is made of an elastomeric material and incorporating a metal reinforcing plate of the body, and the body of the insulating track segment is provided with a plurality of inserts defining the sliding surface of the insulating track segment, the inserts being made of ceramic. 2. The segment according to claim 1 , wherein the insulating track segment has a through-hole designed to receive a suitable fastening system. 3. A ground power supply system, comprising a power supply and at least one insulating track segment according to claim 1 . 4. The ground power supply system according to claim 3 , wherein the insulating track segment is anchored directly into a concrete slab buried in a roadway. 5. The ground power supply system according to claim 3 , wherein the insulating track segment is anchored directly in a roadway.
