The dimensional rhomboid-shaped contact suspension is a continuous and high quality device for the transmission of electrical energy EPS even in cramped dimensions. A distinctive feature of mechanical calculation of any contact
suspension is its interaction, taking into account the mutual arrangement of the wires forming the suspension. Spatial contact suspension has many more design features than chain vertical suspension. When the load-bearing cable is located away from the track and the contact wires are arranged in the form of a rhomboid, the horizontal forces generated in the suspension correspond to the vertical component forces. Taking into account the forces operating in three
projections, the three-dimensional contact suspension allows you to accurately describe the position of the contact wires and load-bearing cables, their blades.
