The main activity in this area is the design of electrification and reconstruction of the railway contact network of the 3 kV DC power supply system at a rolling stock speed of up to 250 km/h, 25 kV AC and 2x25 kV industrial frequency 50 Hz power supply systems at a rolling stock speed of up to 400 km/h.
The main works performed on the contact network are:
- measurement and survey work of the contact network devices of stations, railroad tracks, as well as artificial structures on both operating and being electrified railways;
- electrical calculations of traction energy system;;
- design of the contact network and additional wires of the longitudinal power supply along the supports of the contact network;
- tracing and design of overhead power supply lines for traction energy;
- design and reconstruction of the contact network of docking stations of various current types;
- staged reconstruction of the contact network with consideration to the reconstruction of the tracks;
- design of the contact network in the depot workshops;
- reconstruction of the contact network in the construction area of overpasses and other artificial structures;
- design of the contact network in tunnels;
- author's supervision of the contact network construction;
- development of design documentation for the contact network passage in artificial structures.
In the design process, Lengiprotrans uses software of its own development.
JSC Lengiprotrans performs works on the electrification of the aboveground express and is ready to design the electrification of the city high-speed tram, as well as electrification in quarries.
Our specialists have experience in designing objects abrod, including in accordance with international standards.
