Ngokuvamile, kunezinhlobo ezintathu zeizintambo ezingezona ezensimbi ezingaphezulu kwe-fiber optic, GYFTY, GYFTS, kanye ne-GYFTA.I-GYFTA iwumgogodla ongaqinisiwe, i-aluminium armored fibre optic cable.I-GYFTS iwumgogodla ongaqinisiwe ongeyona eyensimbi, intambo yensimbi ye-armored fibre optic.
Ikhebula le-GYFTY fibre optic lithatha isakhiwo esisontekile se-loose-layer, futhi i-optical fibre imbozwe eshubhuni elixegayo elenziwe ngezinto ze-high-modulus polyester, futhi ishubhu ligcwaliswa ngenhlanganisela engangeni manzi.Ishubhu elixegayo (kanye nentambo yokugcwalisa) lisontekile lizungeze i-non-metallic central reinforcement (FRP) libe yinkambo yekhebula elihlangene, futhi izikhala kunkambo yekhebula zigcwaliswa ngamafutha avimba amanzi.Extri-polyethylenee sheath ngaphandle tyena ikhebulaumnyombo.
Ikhebula le-GYFTA le-fiber optic lamukela isakhiwo esisontekile se-loose-layer, futhi i-optical fibre imbozwe eshubhuni elixegayo elenziwe ngezinto ezisezingeni eliphezulu ze-polyester, futhi ishubhu ligcwaliswa ngenhlanganisela engangeni manzi.Ishubhu elixegayo (kanye nentambo yokugcwalisa) lisontekile lizungeze i-non-metallic central reinforcement (FRP) libe yinkambo yekhebula elihlangene, futhi izikhala kunkambo yekhebula zigcwaliswa ngamafutha avimba amanzi.Izikhali ze-aluminium zangaphandle ze-cable core zigoqwe ngobude, bese i-polyethylene sheath ikhishwa.I-GYFTS iyisakhiwo esifanayo ne-GYFTA, efaka esikhundleni sezivikelo ze-aluminium ngeteyipu yensimbi eboshwe kabili.
Ayikho into yensimbi esakhiweni se-GYFTY, elungele izindawo zombani, izindawo zamandla kagesi aphezulu, nezindawo ezinokuphazamiseka okunamandla kazibuthe kagesi.Ngokuvamile, izintambo ze-GYFTA ne-GYFTS fibre optic nazo zingasetshenziselwa ugesi, ezindaweni ezinezidingo eziphansi zemvelo.I-FRP engeyona eyensimbi i-central reinforcing core, ukusebenza kahle kwe-tensile, intambo ye-fiber optic elwa ne-anti-conductive Izici zomkhiqizo: ukuqinisa okungezona ezensimbi (FRP), ezifanele izindawo zombani, izindawo ezinamandla kagesi aphezulu, ukulwa nombani;Ukushaqeka, kungagotshwa ngokuphindaphindiwe, kusontwe, ukusonteka, ukugoba (i-angle yokugoba engeqi ku-90 °), ukudubula kwesibhamu, njll., ngezakhiwo ezinhle zemishini;umjikelezo wokushisa ozinzile, igobolondo eliphelele, ukuconsa okunqanda ukubola, ukubuyiswa komlilo nezinye izindawo ezinhle Ukusebenza;Ifayibha elawulwa ngokunembile ubude obudlulele kanye nephimbo lokuxhuma ikhebula kuqinisekisa ukuthi ikhebula le-fiber optic lisebenza kahle kakhulu nezici zokushisa;iminyaka yokuphila ingaphezu kweminyaka engama-30.Isisindo esincane, ubude bekhebula elincane, nomthwalo omncane emibhoshongweni.
