ANCHOR SECTION OF COMPENSATED SYSTEM WITH CATENARY SUSPENSION OF HIGH-SPEED RAILWAY Russian patent published in 2005 - IPC

Abstract RU 2266212 C1

FIELD: electrified railways; catenary suspension systems.

SUBSTANCE: proposed device contains end spans, transient and intermediate spans, middle anchor with contact wire and carrier cable interacting by means of droppers. Supporting structures in form of intermediate and transient spring and springless support units furnished with turnable brackets and locks are provided. Spring cables is spring support units are of length equal to 15-20 m with tension of 250 daN-450 daN. Distance between spring support unit and underspring dropper is 4.5 - 5.5 m, distance between spring support unit and first non-spring dropper is 14-15 m. Non-spring dropper are installed in spans between support units at a distance of 8-10 m from one another. Intermediate spans are made with central dropper. Tension of carrier cable is 1400-1800 daN, and that of contact wire, 1200-2000 daN.

EFFECT: reduced coefficient of elasticity of contact suspension, provision of high quality of current collecting with rail vehicles running at speed of 180-200 km/h.
