AC overhead power transmission and distribution lines (high voltage (HV), medium voltage (MV) and low voltage(nN)) are designed to transmit electricity. The task of 110 kV WN lines is to transmit power from wind farms, power plants or highest-voltage LV/WN (e.g. 220/110 kV) transformer/distribution stations to WN/SN (110/15 kV) transformer/distribution stations, or directly to large industrial plants, whose power requirements range from about 5 MW to about 150 MW. The task of MV 15-30 kV overhead lines is to transmit and distribute power from WN/SN (110/15 kV) transformer/distribution stations to MV/nn (15/0.4 kV) transformer/distribution stations, or directly to medium-sized industrial plants, whose power demand ranges from about 2 MW to 15 MW. The purpose of the 0.4 kV nN overhead lines is to transmit and distribute power from SN/nn (15/0.4 kV) transformer-distribution stations to small industrial plants or households, whose power demand is up to 70 kW.
Distances of power lines from buildings and roads
Distances of power lines must be taken into account in the design of line routing and site development. Power lines that run near roads should be designed and constructed in such a way that during operation they do not cause obstruction to vehicular and pedestrian traffic, as well as do not cause obstruction to the maintenance of these roads, so they must be constructed in accordance with the conditions stated in the road manager's permit.
We design, build and upgrade overhead power lines in the field:
- Implementation of investments in the "build" system for entire facilities or their separated parts (including the establishment of easements and full development of formal and legal issues),
- Implementation of investments in the design and build ("turnkey") system,
- Modernization, reconstruction and construction of overhead lines of all voltage levels (MV, 110 kV, 220 kV, 400 kV, 750 kV), in particular:
- Installation and erection of tubular, lattice and prestressed concrete columns,
- Construction of foundations and grounding for poles,
- protection of the surface of the poles against corrosion,
- Removal of collisions and implementation of intersections with existing infrastructure
- Installation of the necessary line accessories, insulator chains,
- Installation and adjustment of working (including high-temperature), lightning protection and OPGW cables.
LV, MV and HV cable lines
- Implementation of investments in the "build" system for entire facilities or their separated parts (including the establishment of easements and full development of formal and legal issues),
- Implementation of investments in the design and build ("turnkey") system,
- Execution of MV cable systems, excavation and laying of medium-voltage cable routes, installation of overhead and indoor MV couplers and heads,
- Construction of fiber optic tracts,
- Construction of 110 kV, 220 kV and 400 kV cable systems, excavation and laying of cable routes (including the implementation of drilling),
- Performing full measurements and commissioning of cable lines,
- Installation of couplers and indoor and overhead heads.
