Isikhokelo esipheleleyo seZixhobo zeCable zeCommon Optical Fiber | Indlela yokukhetha izixhobo zeCable ezifanelekileyo kwiindawo ezahlukeneyo

Kuyilo lwentambo yefayibha ye-optical (OFC), ukukhetha izinto ezifanelekileyo kubalulekile. Iindawo ezahlukeneyo zokusebenza—ezifana nokubanda kakhulu, amaqondo obushushu aphezulu, ukufuma, ukufakwa ngaphandle, ukugoba okuqhubekayo, okanye ukuhamba rhoqo—zibeka iimfuno ezahlukeneyo kwizixhobo zentambo ye-optical. Apha, sishwankathela izixhobo eziphambili ezininzi ezisetyenziswa rhoqo kushishino, sihlalutya iimpawu zazo zokusebenza kunye nezicelo ezisebenzayo ukunceda ukuphucula uyilo lwakho lwentambo yefayibha ye-optical kunye nokukhetha izinto.

1. I-PBT (iPolybutylene Terephthalate) — Eyona nto ixhaphakileyo kwiityhubhu ezikhululekileyo

I-PBTyeyona nto isetyenziswa kakhulu kwiityhubhu ezikhululekileyo kwiintambo zefayibha ye-optical. Iiplastiki zekhebula eziqhelekileyo zihlala ziqhekeka xa kushushu kwaye zithambe xa kushushu kakhulu. I-PBT eguquliweyo, umzekelo, eneziqendu zetyathanga eziguquguqukayo, iphucula kakhulu ukumelana nefuthe lobushushu obuphantsi kwaye inokuhlangabezana neemfuno ukuya kuthi ga kwi--40°C. Ukongeza, i-PBT inika ukuqina okugqwesileyo kunye nozinzo olulinganayo kubushushu obuphezulu, iqinisekisa ukhuseleko oluthembekileyo kwiintambo phantsi koxinzelelo lobushushu. Ukusebenza kwayo okulinganiselayo, ixabiso elifanelekileyo, kunye nokuguquguquka kwenza ukuba ibe lukhetho oluqhelekileyo kwiintambo zonxibelelwano zangaphandle, iintambo zohambo olude, kunye nezakhiwo zeentambo ze-ADSS.

2. I-PP (iPolypropylene) — Ukuqina Okuphezulu Kobushushu Obuphantsi kunye Nokumelana neHydrolysis

I-PP ifumene ingqalelo kwizinto zekhebula ze-optical ngenxa yokuqina kwayo okuphantsi kobushushu, okuthintela ukuqhekeka kwiimeko ezibandayo kakhulu. Ukumelana kwayo ne-hydrolysis kukwangcono kune-PBT, okwenza ukuba ifaneleke kwiindawo ezifumileyo okanye ezinamanzi amaninzi. Nangona kunjalo, i-PP ine-modulus kunye nokuqina okuphantsi kancinci xa kuthelekiswa ne-PBT, ngoko ke ukusetyenziswa kwayo kufuneka kuqwalaselwe ulwakhiwo oluthile lwekhebula. Umzekelo, iintambo ezikhaphukhaphu, iintambo ze-hybrid zangaphakathi nangaphandle, okanye izakhiwo zeetyhubhu ezikhululekileyo ezifuna ukuguquguquka okuphezulu zinokukhetha i-PP njengenye indlela.

3. I-LSZH (I-Low Smoke Zero Halogen) — Izinto zeJacket yeCable eziLungelelanisa neNdalo

I-LSZHYeyona nto isetyenziswa kakhulu yijakethi yekhebula enobuhlobo nokusingqongileyo. Iifomyula ze-LSZH ezisemgangathweni ophezulu, ezifunyenwe ngeenkqubo zepolymer ezikhethekileyo kunye nobuchwepheshe bokugcwalisa, zinokuhlangabezana neemfuno zempembelelo ephantsi yobushushu obuphantsi -40°C kwaye ziqhubeke nokusetyenziswa ixesha elide kwi-85°C. Kwimeko yomlilo, i-LSZH ikhupha umsi omncinci kwaye ayinayo igesi ye-halogen, nto leyo ephucula kakhulu ukhuseleko lweentambo zangaphakathi, iintambo zeziko ledatha, kunye neentambo zezixhobo zikawonke-wonke. Ikwabonelela ngokumelana okuhle nokuqhekeka koxinzelelo lokusingqongileyo kunye nokubola kweekhemikhali, okwenza kube lukhetho oluguquguqukayo kwiijakethi zekhebula zangaphakathi nezangaphandle.

4. I-TPU (i-Thermoplastic Polyurethane) — “Ukumkani” woBume obuNgaphantsi boBushushu kunye noKuxhathisa ukuGxobhoza

I-TPU yaziwa ngokuguquguquka kwayo kunye nokuqina kwayo phantsi kwamaqondo obushushu aphantsi kakhulu. Ngokungafaniyo ne-PVC, i-TPU ihlala ithambile kakhulu kwaye ayiqhekeki. Ikwanokumelana nokukrazuka okubalaseleyo, ioyile, kunye nokukrazula, okwenza ukuba ilungele ukuhamba kweentambo, kubandakanya iintambo ze-drag chain, iintambo zezithuthi, iintambo zemigodi, iintambo zerobhothi, kunye nezicelo ze-automation yemizi-mveliso. Qaphela ukuba ukumelana nobushushu obuphezulu kunye ne-hydrolysis ye-TPU kuxhomekeke kudidi oluthile, ngoko ke ukukhetha iifomyula ezikumgangatho ophezulu kubalulekile.

5. I-PVC (iPolyvinyl Chloride) — Ukhetho lweJacket yeCable eSebenza ngexabiso eliphantsi kunye nemida yobushushu obuphantsi

I-PVC isasetyenziswa kwiintambo ezithile ze-optical ngenxa yexabiso layo eliphantsi kunye nokulula kokuyicubungula. Nangona kunjalo, i-PVC eqhelekileyo iyaqina kwaye inokuqhekeka ngaphantsi kwe--10°C, nto leyo eyenza ukuba ingafaneleki kwiimeko ezibandayo kakhulu. I-PVC enobushushu obuphantsi okanye engangeni kubanda inganciphisa ubushushu bokutshintsha kweglasi ngokusebenzisa iiplastiki, kodwa oku kunokuphazamisa amandla oomatshini kunye nokumelana nokuguga. I-PVC ke ngoko ifanelekile ngakumbi kwiiprojekthi ezinobunzima beendleko kwiindawo ezizinzileyo, ezifana nokufakelwa okuqhelekileyo ngaphakathi okanye ukuseta iintambo zexeshana.

6. I-TPV (i-Thermoplastic Vulcanizate) — Ukudibanisa i-Elasticity yerabha kunye ne-Plastic Processability

I-TPV idibanisa ukuthamba kwerabha kunye nokusebenziseka kweplastiki. Inika ukumelana okuhle kakhulu nobushushu obuphezulu nobuphantsi, kunye nokuchasana okubalaseleyo kwemozulu kunye ne-ozone. Ukuguquguquka nokuqina kwe-TPV kuyenza ifaneleke kwiintambo ze-optical zangaphandle, iingcingo zeemoto, kunye neentambo eziguquguqukayo. Njengezinto zokwakha, i-TPV ilungelelanisa iimpawu ze-TPU kunye ne-PVC, ibonelela ngokuguquguquka okubalaseleyo kwesakhiwo kunye nokuqina kokusingqongileyo.

7. I-XLPE (iPolyethylene edibeneyo) — Izinto zokukhusela ubushushu obuphezulu kwiintambo ze-Optical kunye nezombane

I-XLPE, ngokusebenzisa ukuxhumanisa, kwandisa ukumelana nobushushu kwaye ingasebenza ngokuqhubekekayo ngaphezulu kwama-90°C. Ikwabonelela ngamandla oomatshini aphezulu kunye nokumelana noxinzelelo. Nangona i-XLPE isetyenziswa kakhulu ekugqumeni intambo yamandla (umz., 1kV–35kV), ngamanye amaxesha isetyenziswa kwiintambo ze-optical zokuqinisa okanye usetyenziso lobushushu obuphezulu. Iimpawu zayo zobushushu kunye nezoomatshini zenza ukuba ifaneleke kwiintambo ze-optical ezikhethekileyo kwiindawo ezinzima.

Ukukhetha Izinto zeJacket yeCable ye-Optical — Iimeko zesicelo zibalulekile

Ukukhetha izixhobo zekhebula ze-optical ezifanelekileyo kufuna okungaphezulu kokuphonononga idatha yobugcisa; kufuneka kuqwalaselwe neemeko zokwenyani zesicelo:

Ufakelo oluQinisekisiweyo (ngaphandle, i-duct, i-aerial): LSZH, TPV, XLPE
Izicelo zokufuduka (iitsheyini zokurhuqa, iirobhothi, izithuthi, ukumbiwa kwemigodi): TPU
Ukubanda Okugqithisileyo (-40°C okanye ngaphantsi): I-PBT eguquliweyo, i-PP, i-TPU
Iintambo zangaphakathi, Ukusetyenziswa okuqhelekileyo, iiprojekthi ezinobuzaza kwiindleko: I-PVC (icetyiswa kuphela phantsi kweemeko ezithile)

Akukho sisombululo "esifanela bonke" kwizixhobo zekhebula le-optical. Ukhetho kufuneka lusekelwe kuvavanyo olupheleleyo lwesakhiwo sekhebula, iimeko zokufakelwa, uhlahlo lwabiwo-mali, kunye nokuthembeka kwexesha elide.
