In the paper, failure outage statistics in 6–10 kV overhead electric grids of one of the largest electric grid companies in the European part of the country were analyzed to clarify the reliability characteristics of their elements. Failure intensity and mean restoration time for covered and uninsulated overhead lines, low-oil and vacuum circuit breaker cells, power transformers and secondary electrical grid elements were obtained. The obtained reliability characteristics of elements should be used in the tasks of technical justification and selection 6–10 kV overhead electrical grid preferred structure.
