Following exhaustive research, the All-Union Order of the Red Banner of Labor Scientific Research Institute of Railroad Transport (TsNII) has developed a solution to the problem of deficiencies in the static and dynamic characteristics of pantographs and catenary suspension; these deficiencies cause sections of the contact wire to wear out and thereby necessitate replacement of the wire. The solution proposed is a catenary system of absolutely constant tension. This system makes use of the torsional action of the messenger wire produced by a level suspension unit. Procedures for mounting the levered catenary in compensated, semicompensated, and rhombic arrangements are provided, as well as data obtained from a broad experimental research base. Also given are special mounting procedures for traffic speeds over 160 km/hr and the levered catenary's advantages over sprung catenary.
