Samojlenko M. Portals of external switch-gears with guaranteed reliability and longevity

The problems of providing reliability and longevity portals of external switch-gears in the process of design and reconstruction at the expense of perfecting calculation methods of account and constructive form have been considered. The experimental, analytical and numerical methods of researches have been used. The models of durability of anticorrosive coatings, reliability coefficients with reaped to wind and ice-crust loads, quantitative values of probability for trouble-free service of portals, as well as a new structure of a portal have been offered. The results have been introduced into the normative documentation and in the processes of inspections. Two patents of Ukraine have been got. The sphere of usage is power engineering.
