Overhead MV/LV networks
- Positioning of poles and calculation of spans.
- Installation of overhead MV and LV lines.
- Installation of pole-mounted switches and breakers.
- Earthing and lightning protection.
Solutions
Electrical works
Construction and maintenance of power networks.
We build and maintain overhead and underground networks, as well as prefabricated and masonry transformer substations. We also upgrade existing substations.
Key points
- ONEE / BE type MT/BT1 approval for MV/LV network execution.
- Overhead and underground networks, new builds and upgrades.
- Prefabricated and custom-built distribution substations.
- Maintenance and refurbishment of existing substations.
Scope of work
Underground networks
- Installation of underground MV and LV cables.
- Switching, branching and protection boxes.
- Manholes and cable jointing.
- Fault detection and location.
Distribution substations
- Prefabricated substations, skid-mounted or masonry-built.
- Installation of MV/LV transformers and switchgear.
- TIPI boards and reduced urban boards.
- Control and commissioning of slave substations.
Maintenance and upgrades
- Assessment of the condition of networks and substations.
- Replacement of failed equipment.
- Preventive and corrective maintenance.
- Bringing existing substations back into compliance.
