The development of industry and large cities demanded the building of energy, railway, road and airport systems. We cooperate in the building of these systems by mounting the electro installations for:

- distributing transformer stations 35 to 110 kV
- tunnels (lighting, ventilation, signalization, video control)
- purifying plants
- water and fecal pumping sites
- computer networks for traffic control
- lighting of runways for take-off and landing of planes
- exterior lighting (parking places, sports grounds)
- information panels
