Equipment is repaired with regard to its real technical status following preliminary inspections, expert evaluations, technical diagnostics and control. Primary aim of the repairs is the restitution of equipment life by replacing aerials fuses for over-voltage limiter, oil-filled incoming lines of transformers and 110 kV switchers for incoming lines with RIP-isolation and stick-pedestal insulator of disconnect switches, defect porcelain isolator for polymer ones, worn-out overhead protection cables for aluminum-steel conductors, compression and bolted fittings for spiral hooping, defective wood for wood steeped in pollution-free antiseptic.

During the reported period we laid a special emphasis on building renovation initiated after exploitation-educed defects. Completion of target repair volumes, defined by 2010 repair program, is 112%. Generally, during 2010 we repaired:
