We plan repairs and put equipment under repair after analyzing its technical status identified by preliminary inspections, expert valuations and technical diagnostics according to regulatory and administrative documents. The primary aim of the repairs is restitution of equipment life by replacing key parts and components (aerial fuses for over-voltage limiters, OF incoming lines of transformers for incoming lines with RIP-isolation and stick-pedestal insulators of disconnect switches, defect porcelain isolators for polymer ones, worn-out overhead protection cable for a new one, compression and bolted fittings for spiral hooping, defective wood for wood steeped in pollution-free antiseptic, etc.). Overall repair plan in 2013 totaled RUR 1 519 123 thous. Overall repair program in 2013 totaled RUR 1 578 113 thous. or 104%.
