Description
Glowice koncowe sluza do zabezpieczenia konca kabla, chroniac go od uszkodzenia i zawilgocenia wnetrza oraz umozliwiajac dolaczenie kabla do urzadzen.Dotychczas stosowane glowice koncowe sa wy¬ konane z odlewu zeliwnego, do którego przykre¬ cone sa okute izolatory porcelanowe. Powyzsza konstrukcja powoduje to, ze glowice koncowe sa *) Wlasciciel patentu oswiadczyl, ze twórcami wynalazku sa inz. mgr Kazimierz Kolbinski i inz.Grazyna Lewaszkiewicz. duze i niewygodne przy montazu. Wada ich jest niemoznosc krzyzowania faz przy dolaczaniu glo¬ wicy do urzadzen.Zastosowanie konstrukcji glowicy o zmniejszo¬ nych wymiarach wymaga zabezpieczenia kabla przed wyladowaniami slizgowymi. W tym celu za¬ stosowano na koncach zyl obwój z tasmy pólprze- wodzacej wykonanej np. z gumy pólprzewodzacej, z pólprzewodzacego polichlorku winylu lub z in¬ nych pólprzewodzacych plastyków. Zamiast obwoju moga byc zastosowane nasuwane koszulki z ma¬ terialu jak wyzej.Dlugosc nawiniecia materialu pólprzewodzace- go i jego opornosc sa uzaleznione od wielkosci koniecznego spadku napiecia, który ma byc uzy¬ skany w danym typie kabla. PLThe end heads are used to secure the end of the cable, protecting it from damage and moisture inside and enabling the connection of the cable to the devices. The above design means that the end heads are *) The patent owner stated that the inventors of the invention are Eng. Kazimierz Kolbinski and Eng. Grażyna Lewaszkiewicz. large and inconvenient to assemble. Their disadvantage is the inability to cross the phases when connecting the head to the devices. The use of the head design with reduced dimensions requires the protection of the cable against sliding discharges. For this purpose, a coil made of semi-conductive tape made of, for example, semi-conductive rubber, semi-conductive polyvinyl chloride or other semi-conductive plastics was used. Instead of a wrapping, slip-on sheaths of a material as above may be used. The winding length of the semi-conductive material and its resistance are determined by the amount of voltage drop necessary to be obtained for the type of cable. PL
