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
