Abstract
An insulating support for a ground electrical power supply track is provided. The insulating support is intended for a terrestrial transport system, in particular of the tramway type, and is in the form of a profile-member of insulating material which includes a substantially planar upper face intended to receive elements of the electrical power supply track and a planar lower face intended to be supported directly or indirectly on the ground. The profile-member is provided with a longitudinal groove is arranged on the upper face in order to receive a conductive track element. The profile member is also provided with a web which connects the upper face to the lower face. At least one longitudinal supply conduit intended to receive a supply line of the network extends through the web. The groove and each supply conduit are arranged centrally and symmetrically about a longitudinal center plane of the support perpendicular relative to the upper face.
