Line maintenance worker - Eltel Networks

Power line exploitation

Operation of power lines with a voltage from 0.4 kV to 750 kV:

  • periodic inspection and line reviews
  • replacement and repair of supporting structure elements
  • line grounding repair
  • replacement and repair of lightning and working cables, line fittings and glass, ceramic and composite cap insulator chains
  • corrosion protection of structures
  • replacement and strengthening of pole structures and foundations
  • reconstruction of 110 kV, 220 kV, 400 kV and 750 kV power lines
  • raising the pole structure
  • anti-corrosion protection of pole surfaces and repair of foundations
  • line thermovision inspections
  • liquidation of failures and mining damages occurring in power lines
  • inspection and diagnostics of power lines from the helicopter deck (registration of the line route using time-lapse photos from multiple cameras, obtaining a virtual network image, laser scanning, thermal imaging diagnostics and the Korona method, numerical terrain modeling, orthophotos, etc.)
  • measurements of the line tension and construction parameters
  • performance of works performed under voltage (Live Line Work) on power lines from 220 kV to 750 kV, including: insulation replacement, cable repair, replacement or repair of spacers in a multi-wire bundle, anti-corrosion protection of pole structures
