Annual report 2009


History of the company

In 1954 – estabilished company called „Elektrizace železnic Praha“ (translated „Railways Electrification Prague“)

At the beginning OCL for speeds up to 120 km/h were developed for 3 kV DC and 25 kV AC traction systems

Since 1954 our company electrificated all of the main lines in Czechoslovakia and urban mass transportation lines

In 1992 the company was privatized and transformed into joint-stock company

In the 90‘s we have developed OCL for speeds up to 200 km/h for 3 kV DC and 25 kV AC traction systems

In 2007 the innovated OCL types for speeds up to 260 km/h were certified according to TSI


After privatization we started to supply too: Traction substations 750 V DC, 1500 V DC, 3 kV DC (including

substation 110kV, 22 kV AC) and 25 kV AC (including sub. 110 kV) Electrical coach pre-heating system Electrical heating of switches Service and maintenance Projects (electrotechnological units)

Our company offers not only OCL and electrotechnological units construction but also owns a powerful production base.

Production base consists of 2 production centres (1 for steel structures, 1 for OCL accesories and switchgears)

The construction works are implemented by 4 centres (2 for railway OCL, 1 for electrotechnological units, 1 for urban mass transportation).

Production centre Vlkov, Czech Republic:

-engineering and manufacturing of steel lattice masts, tubular masts and cross-beams of all types - production of lighting towers- cutting, machining and working of materials- steel structure anti-corrosion protection


Production centre Česká Třebová, Czech Republic:

-production of OCL accesorries (motor drives, cantilevers, clamps, fittings, breakdown fuses)-production of air insulated LV and HV switchgears (24/110 V DC, 230/400 V AC, 750 V DC, 1500 V DC, 3 kV DC, 25 kV AC and others)- acredited mechanical and electrical laboratory



Our newest product - Container rectifier substation 22 kV AC/3 kV DC

OCL construction centres-Excavation and foundation works for OCL structures-montage and demontage of standard and special masts and cross-beams -montage and demontage of cantilevers, conductors, feeders, tensioning equipment, optical cables


Technological units construction centre-Installing substations 110 kV AC, 22 kV AC, 750 V DC, 1500 V DC, 3 kV DC, 25 kV AC equipment-Programming of PLC and protections-Set in operation
