Power engineering
Electricity distribution is a fundamental part of society’s infrastructure. At OneCo, we provide power engineering services that enable the transmission and distribution of electricity from the point of generation to end users.
At OneCo, we work on cable, line and substation projects in the 0.4–420 kV voltage range. Our projects include new construction, expansion, maintenance and emergency repairs to existing electricity networks.
Project management of installation work
We have experienced project managers who handle every aspect of your project, from planning to implementation.
Switchyard installation (GIS)
We install complete switchgear assemblies, including control equipment and auxiliary power systems.
Expansion of power lines
We are extending existing power lines to connect new substations, up to 420 kV.
Fibre and telecoms installation/OPGW
We install fibre-optic cables and telecommunications equipment on power lines.
Medium-voltage switchgear and substations
We build and install equipment for distributing electricity to households and businesses.
Converter and rectifier stations for rail transport
We ensure that trams, trains and other electric vehicles have the electricity they need.
Cable works
We lay, splice and terminate cables for electricity distribution.
Switch
We carry out installation and circuit-breaker testing on circuit-breakers up to 420 kV.
Network and subscriber stations
We build and install equipment to supply electricity to specific areas or customers.
Low-voltage switchgear
We manufacture and install electrical distribution equipment for buildings.
Back-up power
We ensure that the electricity supply is not interrupted in the event of a power cut.
Construction Power
We supply electricity to construction sites.
