Ukuqinisekisa ukuba i-Optical Coble ye-Cable ikhuselwe ngoomatshini, i-thermal, yemichiza, kunye nomonakalo onxulumene nomonakalo, kufuneka ixhotywe nge-sheath okanye i-sheers engaphandle. La manyathelo ayindisa ngokufanelekileyo inkonzo yobomi beentsinga.
I-sheaths eqhelekileyo isetyenziswa kwiintambo ezihamba phambili zibandakanya i-sheaths (i-Aluminium-Polythylene Biaths), i-S-Pheiaths (i-Steel-Polythylene), kunye ne-Palyethylene. Kwiintambo ezinzulu zamanzi, iibhulukhwe ezitywiniweyo zityhutywe.
I-Polythyylene Heaths zenziwa ukusuka kwi-intanethi-uxinzelelo olune-intanethi, ukuxinana okuphakathi, okanyeIzinto eziphezulu ze-Polythylene, vumela umgangatho we-GB / T15065. Umphezulu we-Poalthylene Heathylene Heath kufuneka ithole kwaye iyunifomu, ingenazibhokhwe ezibonakalayo, amaPinholes, okanye utyala. Xa isetyenziswa njenge-heath engaphandle, ubukhulu obufanelekileyo bufanele bube yi-2.0 mm, ngobuncinci be-1.6 mm, kunye nobubanzi bomgangatho kuwo naliphi na icandelo le-ross akufuneki lingaphantsi kwe-1.8 mm. Iipropathi zoomatshini kunye nezomzimba zecandelwana kufuneka zifezekise iimfuno ezichazwe kwi-YD / T90-1997, itafile 4.
I-a-sheath iqulathe i-surer barer faker eyenziwe ukuba igcinwe inesidima kwaye ibiliweIteyiphu ye-Aluminum ye-Aluminum, zidityaniswe ne-Polithylene ye-Polithylene emnyama. I-Polythylene Heath Bondys ngeteyiphu yengca kunye nemiphetho ye-oxam yetephu, enokuqiniswa ngokuqhubekayo ukuba inamathele. Ububanzi obugqithisileyo betheyiphu yenxalenye ayifanelanga ukuba bungaphantsi kwe-6 mm, okanye intambo yokuthuthwa kweedayamitha ngaphantsi kwe-9.5 mm, akufuneki ukuba kungabi ngaphantsi kwe-20% yoowangqanga. Ubungqingqwa bobutyula be-Polythylene Sheath ngu-1.8 mm, ngobuncinci obunobuncinci be-1.5 mm, kunye nobubanzi obungaphantsi kwe-1.6 mm. Ngohlobo lwe-53 labasebenzi, ubukhulu becala yi-1.0 mm, ubuncinci bomgangatho ophantsi yi-0.8 mm, kunye nomndilili ophakathi ongu-0.9 mm. Iteyiphu ye-aluminium-yeplastiki kufuneka ihlangabezane ne-YD / T723.2 emiselweyo, itayile ye-aluminium enobukhulu bee-0,20 mm okanye i-0.15 mm (ubuncinci i-0,05 mm.
Amalungu ambalwa etayitile avunyelweyo ngexesha lemveliso yentambo, enike indawo yokudibana engaphantsi kwe-350 m. La malungu kufuneka aqinisekise ukuqhubeka kombane kwaye abuyisele ungqimba lweplastiki. Amandla ekudibaniseni akufuneki abe ngaphantsi kwe-80% yamandla eteyiphu yoqobo.
I-S-Sheati isebenzisa umsitho womsitho we-swarier olwenziwe nge-ixesha elide esongelweIteyiphu yentsimbi yentsimbi, zidityaniswe ne-Polithylene ye-Polithylene emnyama. I-Poalyethylene Heath Bonds ngeteyiphu yengca kunye nemiphetho ye-oxas yeteyiphu, enokuqiniswa ngokunamathela xa kukho imfuneko. Iteyiphu yengcambu ye-cocageted kufuneka yenze isakhiwo esifana nendala emva kokusonga. Ububanzi obugqithisileyo akufuneki bube ngaphantsi kwe-6 mm, okanye i-cable i-cardater ibe ngaphantsi kwe-9.5 mm, akufuneki ukuba ibe ngaphantsi kwe-20% yoowangqanga. Ubungqingqwa bobutyula be-Polythylene Sheath ngu-1.8 mm, ngobuncinci obunobuncinci be-1.5 mm, kunye nobubanzi obungaphantsi kwe-1.6 mm. Iteyiphu yentsimbi yentsimbi yentsimbi kufuneka ihlangane ne-YD / T723.3, iteyiphu yentsimbi inomgangatho we-0.15 mm (ubuncinci i-0.13 mm) kunye nobubanzi befilimu ye-0.05 mm.
Amalungu eTayile edityanisiweyo avunyelwe ngexesha lemveliso yentambo, enesithuba esidibeneyo sama-350 m. Iteyiphu yentsimbi kufuneka ithelekise i-butt-qho, iqinisekisa ukuqhubeka kombane kwaye ibuyisele umbulelo. Amandla ekudibaniseni akufuneki abe ngaphantsi kwe-80% yamandla etyhefu ye-themo.
Iteyiphu ye-aluminium, i-tepe yensimbi, kunye ne-metallic iileyile ezisetyenziselwa izithintelo zokufuma kufuneka zigcine ukuqhubeka kombane ecaleni kobude bentambo. Ngeebhulukhwe ezibhinqileyo (kubandakanya uhlobo lwe-53 labasebenzi), amandla aphesheya phakathi kwe-aluminium okanye iteyiphu yentsimbi kunye ne-polyethylene sheaths, kunye neteyiphu ye-polyethynene, akufuneki ibe ngaphantsi kwe-1.4 N / MM. Nangona kunjalo, xa izinto ezibonakalayo zamanzi okanye ukungqubana kwamanzi zisetyenziswa phantsi kwe-aluminium okanye i-temp yentsimbi, amandla anyibilikisi kwimiphetho ye-Overlapping ayimfuneko.
Olu lwakhiwo lokukhusela olubanzi luqinisekisa ukuqina kunye nokuthembeka kweentambo zamehlo kwiindawo ezahlukeneyo, ukuhlangabezana nemfundo yeenkqubo zonxibelelwano zanamhlanje.
