Tram and Trolleybus OCS

Tram Contact Line, 600 V ss

  • Single contact line with fixed suspension – not tensioned – used at depots, support span up to 25 m
  • Single flexible overhead contact lines – not tensioned, used for tracks with speeds up to 60 km/h (namely inner-city transportation, and places with complicated directional conditions, for example, in curves), support span up to 30 m
  • Single flexible overhead contact lines with suspension wires (delta suspension) – not tensioned, used especially in straight lines, support span up to 35 m
  • Simple overhead contact lines with suspension cables – tensioned by weights, used especially in straight lines, and for suburban and high-speed lines, for speeds up to 80-100 km/h, length of an anchoring section up to 1 400 m, support span up to 54 m
  • Overhead contact lines with catenary suspensions (with messenger wires) – tensioned by weights, used for suburban and high-speed lines, speeds exceeding 100 km/h, length of an anchoring section up to 1 400 m, support span up to 60

Trolleybus Contact Line 600 V ss, 750 V ss

  • Simple overhead contact lines with fixed suspensions – not tensioned, their use limited to, for example, trolleybus depots, halls, etc.
  • Simple flexible overhead contact lines – not tensioned, characterized by overhead contact wire suspensions in curves using flexible curve clamp, and in straight sections using suspensions with parallelograms, in some cases with supplementary cables (delta suspension). They are used namely in inner-city areas, and in places with complicated directional conditions, for example, in curves. Speeds up to 60 km/h, spans of supports up to 30 meters
  • Simple overhead contact lines fully tensioned by weights – with supplementary cables (delta suspension), used in straight lines with speeds up to 80 km/h, lengths of overhead line sections up to 1400 meters, spans of supports up to 54 meters
  • Simple lines tensioned by weights – catenary suspension lines, used for straight lines with speeds exceeding 80 km/h (depending on types of vehicles and road surface quality), lengths of overhead line sections up to 1 400 meters, spans of supports up to 112 meters
