Iinzuzo ezahlukeneyo ze-OPGW intambo ye-optical cable zenza ukuba ibe luhlobo olukhethiweyo lwentambo ye-OPGW optical cable yokwakha kunye neeprojekthi zomgca wokuhlaziya.Nangona kunjalo, ngenxa yokuba iimpawu zemishini yeentambo ze-OPGW zihluke kwezo zeengcingo eziphantsi komhlaba, emva kokuba iingcingo zomhlaba zemigca yokuhambisa i-overhead yangaphambili ithathelwe indawo, umthamo wokuthwala umthwalo weenqaba zokuqala kufuneka uqinisekiswe.Ukuba izibonda kunye neenqaba azikwazi ukuhlangabezana neemfuno zokuthwala umthwalo, ngoko izibonda kunye neenqaba kufuneka zitshintshwe ukuze kuqinisekiswe ukhuseleko lomgca wokuhambisa ngokwawo.
Ukuguqulwa kwenani elikhulu leenqaba kuya kwandisa iindleko zenguqu kunye nobunzima bokwakha, kunye nokwandisa ixesha lokucima kombane, ngakumbi xa i-single-single-short-circuit current of the line inkulu kakhulu kufuphi nendawo yokuphuma yesitishi.Isixa sobunjineli kunye neendleko zenguqu zokutshintsha indawo yepoli yokuqala yomgca omnye ngeepali eziphindwe kabini ziya kuba nkulu.Kule meko, ukutshintshwa kweentambo ze-OPGW kunye neentambo ze-ads optical ziyakwazi ukuphepha ukuguqulwa kweepali ezilodwa kwiipali eziphindwe kabini, kunye neentambo ze-ADSS ezibonakalayo zinokufezekisa ukwakhiwa okungapheliyo kunye nokunciphisa ixesha lokucima umbane.
Xa kuthelekiswa ne-ADSS optical cable, i-short-circuit current eyenziwa yi-single-phase short circuit ye-OPGW optical cable ayinayo impembelelo kuyo.Ngoko ke, icandelo lomgca alidingi ukwakhiwa kunye nomqhubi omhle wokuphambukisa, oko kukuthi, akuyimfuneko ukutshintsha isibonda esisodwa kunye nesibonda esiphindwe kabini.Ezi zinto zilandelayo kufuneka ziqwalaselwe xa kumiselwa iADSS.Khetha indawo yokuxhoma efanelekileyo yokulawula umbane wentsimi yombane ngaphakathi koluhlu olufanelekileyo, ukunciphisa i-corrosion yombane, kunye nokwandisa ubomi benkonzo yentambo ye-optical cable.Ulawulo lwe-Sag.Xa kunzima ukuqinisekisa umgama wokuwela, indawo yokuxhoma kufuneka iphinde ikhethwe.Ukongeza iintambo ze-ADSS kwimigca ekhoyo ifuna ukuqinisekiswa komgama we-crossover, ngakumbi xa kukho ii-crossovers ezininzi ezibalulekileyo kumgca ofanayo.Iintambo ze-ADSS ezibonakalayo zinokwahlulwa zibe yi-high-hanging, medium-hanging kunye ne-low-hanging ngokobude bendawo yokuxhoma.
