Abstract

Za prijenos električne energije koriste se dalekovodi s odgovarajućom ovjesnom opremom i vodičima. Ovjesna oprema koja je ispitana u okviru ovog rada je zatezna stezaljka s pripadajućim vodičem. Zbog sila zatezanja vodiča, dodatnog opterećenja turbulencijom vjetra, vibracijama i dodatnim teretom uslijed snijega i leda može doći do izvlačenja vodiča iz stezaljke te u najgorem slučaju do havarije dalekovoda i prekida napajanja električnom energijom. Da bi se to izbjeglo provode se ispitivanja odgovarajućih elemenata dalekovoda pri različitim vremenskim uvjetima. U ovom radu je ispitana veza zatezne stezaljke s odgovarajućim vodičem pri statičkom vlačnom opterećenju.

Abstract (english)

Transmission lines with the required suspension assembly and conductors are used to transmit electrical power. In this study a tension clamp was tested along with its corresponding conductor. The forces resulting from tensioning the conductor, additional wind turbulence load, vibrations and additonal snow and ice load, might cause the conductor to get pulled out from the clamp. These could even lead to transmission line failure and electrical power cuts. To avoid that, the respective transmission line components were tested under different weather conditions. The connection between the tension clamp and the corresponding conductor under static tensile load was examined.
