Abstract
The overhead contact conductor of an electric railway has sections where one conductor ends and another begins. The ends of two contact conductors are fastened to a section insulator having two insulation strips between which are arranged two arc horns. The insulation strips are constructed of fiber-reinforced plastic. In order to provide increased creep resistance, the lower sides of the insulation strips are positioned above the contact conductor plane and each of the insulation strips is connected with an upright contact bar, the length of which essentially spans the gap between the arc horns. By using spacers, the contact bars are arranged on the insulation strip in such a way that the lower side of the contact bars forms a contact surface for the electric railway current collector, and not the lower side of the insulating strips.
