Engineering research of hinges to provide reliability of overhead power lines (OPL)
Abstract: Abstract. The paper is the logical continuation of the early studies in the field of reliability assurance of overhead power lines located in the southern regions of Ukraine where there are increased glazed ice and wind loads. The paper has given the investigation findings of conductor/clamp systems removed during their replacement on the OPTL 330 kW «Kakhovskaya — Ostrovskaya» and «Kakhovskaya — Dzhankoy» and also of the joint specimens of the arrival for the next suspender. The investigation findings of dismantled specimens have revealed geometric dimensions deviations caused by corrosion and mechanical wear as well as discrepancy between steel components and chemical composition to specified requirements for operation under field conditions. The causes of fault conditions have been established and recommendations directed to the improvement of OPTL operation and energy supply reliability increase have been provided.
Keywords: overhead power lines (OPL), conductor/clamp systems, metallography, microstructure, metal chemical composition, reliability.
