METHOD FOR LINING CABLES ON PILLARS OF CONTACT LINES AND LINES FOR AUTOMATIC BLOCKING OF RAILWAYS

摘要

The aim of the invention is to develop railway telecommunication networks. In the first stage, the railway pillars are examined as to their load-carrying capacity. The cantilevers with take-off rollers are fixed to the pillars which have been recognised as suitable. The take-off rollers serve are used to line a technological cable under stress. A fibre-optical cable is connected to the technological cable and drawn out by means thereof through the take-off rollers at speed of 0.3-0.8 m/s with a maximum deflection but without touching the earth. After that, the fibre-optical cable is fixed to the pillars and stressed up to a value at 5-10 % exceeding a specified stress value. The fibre-optical cable undergoes this stress for a duration not less than 5 min. The supporting holders are then fixed to the pillars and the fibre-optical cable is moved from the take-off rollers to the supporting holders. The inventive method makes it possible to considerably reduce time and cost for developing the fibre-optical communication networks (in comparison with putting the cable in the earth).
