The installation of new wooden poles require more than 1850 cubic meters of timber, 158 km of wire will be replaced by self-supporting insulated wire
In the frames of the repair program will be replaced 5235 insulators. Also in the plan of the second half of the year is repair of  the four lines of 35 kV in Medvezhyegorsk area.
In recent years, the enterprise carries out the replacement of porcelain insulators for polymer. This year will be replaced 836 insulators, next year - another 676. As explained in the Department of maintenance and repair, the polymer support-rod insulators are much more reliable: they are much more resistant to natural phenomena and dynamic loads/ This fact practically  eliminates the risk of an accident during routine switching. In addition, a minimum service life of insulators - 40 years.
