Electricity distribution networks

Electric lines

Overhead lines

  • Activity on overhead lines in bare conductors and/or overhead cable
  • Maintenance of fiber optic networks on the electricity infrastructure
  • Realization of sockets with/without activation of the Metering Unit
  • Installation of mobile earthing devices to confirm correct identification of the line after checking for the absence of voltage.

Underground cable lines

  • Activities on underground cable lines
  • Maintenance of fiber optic networks on the electricity infrastructure
  • Realization of sockets with/without activation of the Metering Unit
  • Carrying out cutting of MV-LV cables for the correct identification of the cable line

Submarine cable lines

Secondary substations

  • Maintenance and/or building construction and/or demolition activities
  • Construction of forced ventilation system in MV / LV cabin room
  • Recovery

LV installation, replacement or recovery

  • Installation/replacement/recovery of low voltage concentrator (LV-C) in secondary substations and/or at pole-mounted transformers to be carried out, normally, in the presence of low voltage.

Metering units, meter taking and reading activities

  • Activations/deactivations of metering units powered by single sockets or installed in LV substations
  • Construction/transfer/demolition/reconstruction
  • Reading service of electric meters (installed at customers’ premises powered by low voltage)

24/7 breakdown calls

  • Interventions aimed at preventing imminent accidents or for eliminating any potential hazard on the Customer’s medium and low voltage electricity grid, with intervention at the workplace

Electric car recharging

  • Installation and maintenance of electric car recharging infrastructure

Fault-finding and cable tests

Main station maintenance

  • Works and interventions regarding civil and electromechanical works (including dismantling and demolition), including specialist electromechanical maintenance
  • Ancillary and Global Services (cleaning of internal and external surfaces, snow removal, pest control and disinfestation, maintenance of green areas, maintenance of technological systems) necessary for the maintenance of Main Stations or similar plants.
  • Failure maintenance (availability and failure intervention)

Ground system checks

  • Ground system inspection service in the transformation cabins and / or secondary substations and pole mounted switch-disconnectors
  • Visual inspection of the accessible ground system parts
  • Checking the continuity of the ground conductors
  • Ground resistance measurement
  • Possible measurement of contact and step voltages (if commissioned)
  • Various and ancillary fulfilments.
