At present there are widely applied on the catenary network of the U.S.S.R. multi-dimensional sectional insulators with polymer insulating elements. Thus on direct current sections SI-2 insulators with AG-4C plexiglass inserts are widely utilized. Alternating current sectional insulators TsNII-2 with polymer insulating elements, which are simultaneously slide blocks coming into contact with the rolling stock current collector runner, are also widely utilized. Analysis revealed that the economical effect from the application of direct current type SI-2u new sectional insulators can be summarized in the following factors: the difference in the price of the traditional insulator and the new one; the difference in the stability of installation into the catenary suspension; the difference in the service periods; and the increase in the reliability of the operation of new insulators in comparison with old ones. The economical effect in a given instance is manifested both in the production sphere and the utilization sphere on the roads as well. These factors are all carefully calculated mathematically in the article. The total economic effect is a saving of 760 rubles per 100 km. of track.
