Ngokubanzi, kukho iintlobo ezintathu zeiintambo ze-non-metallic overhead fiber optic, GYFTY, GYFTS, kunye ne-GYFTA.I-GYFTA yinto engundoqo eyomeleziweyo engeyiyo eyentsimbi, intambo ye-aluminiyam ye-armored fiber optic.I-GYFTS yintsimbi engundoqo eqinisiweyo, intambo ye-armored fiber optic.
Intambo ye-GYFTY ye-fiber optic ithatha i-loose-layer twisted structure, kwaye i-fiber optical ifakwe kwi-tube ekhululekile eyenziwe nge-high-modulus polyester material, kwaye ityhubhu izaliswe yi-compound engenamanzi.I-tube evulekileyo (kunye nentambo yokuzalisa) ijikelezwe malunga ne-non-metallic central reinforcement (FRP) kwi-compact cable core, kwaye izikhewu kwi-core cable zizaliswe ngegrisi yokuthintela amanzi.Extri-polyethylenee sheath ngaphandle tyena intamboundoqo.
Intambo ye-fiber optic ye-GYFTA ithatha i-loose-layer ejijekileyo, kwaye i-fiber optical ifakwe kwi-tube ekhululekile eyenziwe nge-high-modulus polyester material, kwaye ityhubhu igcwele i-compound engenamanzi.I-tube evulekileyo (kunye nentambo yokuzalisa) ijikelezwe malunga ne-non-metallic central reinforcement (FRP) kwi-compact cable core, kwaye izikhewu kwi-core cable zizaliswe ngegrisi yokuthintela amanzi.Isikrweqe se-aluminiyam yangaphandle yesiseko sentambo sisongelwe ixesha elide, kwaye emva koko i-polyethylene sheath ikhutshiwe.I-GYFTS yisakhiwo esifanayo ne-GYFTA, ethatha indawo yesikrweqe se-aluminium kunye ne-tape yensimbi ephindwe kabini.
Akukho nto yentsimbi kulwakhiwo lwe-GYFTY, olulungele iindawo zombane, iindawo zombane ophezulu, kunye neendawo ezinophazamiseko oluqatha lwe-electromagnetic.Ngokubanzi, iintambo ze-GYFTA kunye ne-GYFTS zefiber optic nazo zingasetyenziselwa umbane, kwiindawo ezineemfuno ezisezantsi zokusingqongileyo.I-non-metallic FRP i-central reinforcing core, ukusebenza kakuhle kwe-tensile, i-anti-conductive fiber optic cable Iimpawu zemveliso: i-non-metallic (FRP) yokuqinisa, ifanelekile kwiindawo zombane, iindawo eziphezulu zombane, i-anti-lightning;Ukothuka, kunokugoba ngokuphindaphindiweyo, ukugoba, ukugoba, ukugoba (i-angle yokugoba engadluli kwi-90 °), isibhamu, njl., kunye neempawu ezintle zoomatshini;umjikelo lobushushu obuzinzileyo, sheath epheleleyo, anti-seepage ukuthontsiza, idangatye retardant kunye nezinye iimeko ezilungileyo ukusebenza;Ifayibha elawulwa ngokuchanekileyo ubude obugqithisileyo kunye ne-cable stranding pitch iqinisekisa ukuba intambo ye-fiber optic inokusebenza okugqwesileyo kunye neempawu zobushushu;ubude bokuphila bungaphezulu kweminyaka engama-30.Ubunzima obulula, ubude bekhebula elincinci, kunye nomthwalo omncinci kwiinqaba.
