Annotation: The article is devoted to problems of increasing service performance of power supply structures under restoration. The basic method of increasing the reliability level of power supply objects is an up-to-date elimination of defects in the going structures. The authors have analyzed damages within the near-mast zone of high power transmission towers, outdoor switchgear gantries, and column bases for electrical equipment. Having analyzed the results of examining bearing structures, there were suggested candidates of strengthening structure bases, highs and lows of the given solutions being given in comparison with other methods. The suggested methods being used, it allows to solve a number of problems, in particular, to save money in comparison with a structure replacement and/or in comparison with the costs caused by power cut, and it also allows to make strengthening and repair without any complex mechanization means of a structure discharge. But a decision of either to use or not to use the strengthening technique should be separately made in every case taking into account reasonable financial and maintenance expenses and potentials. The methods of strengthening suggested in the article require the development of a new approach to the problem of restoration repairs and criteria of the adequacy of technical decisions taken.

Keywords: power supply structures, defects and damages, strengthening.
