At the beginning of year 2013 another railway line with newly build catenary with the TRANSCOM’S products was completed. Designed and developed in conjunction with Bulgarian and foreign companies and experts, the parts and assemblies manufactured by TRANSCOM’S allowed setting new speed record on railroad in Bulgaria of 175km/h! For the needs of the railway infrastructure TRANSCOM’S produces and delivers: |
INSULATORS
In the manufacturing process, all fitting elements (respectively the insulators containing them) are subjected to 100% control with test loads as defined by TSRI 007-2006 and EN 50119. The NRIC is using more than 7 000 pcs of insulators manufactured by TRANSCOM’S since 2004, including in extreme climate environment, soiling and operational overloads. There is no registered failure of a composite insulator manufactured by TRANSCOM’S as of to-date. The multi-component technology chosen by TRANSCOM’S ensures flexibility in the manufacture of various designs and meeting the client-specific requirements. The selection of dimensions and V-shaped fixing of cable terminals to the fiberglass rod provide for unsurpassed mechanical strength of the insulators even in the unavoidable cases of prolonged electric arch in real circumstances (due to atmospheric and operational overloads). |
CANTILEVERS
TRANSCOM’S offers two solutions for the hanger pipes:
With view of the technical end economic studies, TRANSCOM’S recommends, as optimal solution, aluminium alloy F31 pipes and fixture of hot dip galvanized, precision cast steel. Using the wide range of fixing elements that TRANSCOM’S produces makes possible any other choice of materials for the pipes of the hanger constructions. |
TENSIONING DEVICES
To respond to the specific needs of the NRIC, TRANSCOM’S company designed and developed a tensioning device for simultaneous compensating of the elongation of both the contact and the messenger wires. The tensioning devices of this type significantly reduce the cost of the tensioning system, with still guaranteed tensioning force, and assured protection of the line when tearing of one or both the contact and messenger wires occur. |

CONCRETE WEIGHTS
TRANSCOM’S products range also includes concrete weight of 25kg, diameter of 410mm and height of 80mm. Thus reducing the total size of the weights-block, a longer travel of the tensioning device is provided. The new manufacturing technology allows producing of weights with height of 40mm and weight of 12,5kg. |
