Iyintoni injongo yoLungiso lweeCable?

Ukukhusela ukuqina kwesakhiwo kunye nokusebenza kombane kweentambo kunye nokwandisa ubomi benkonzo yazo, umaleko wesikhuselo ungongezwa kwisigqubuthelo sangaphandle sentambo. Ngokubanzi kukho iintlobo ezimbini zesikhuselo sentambo:iteyiphu yentsimbiisikrweqe kunyeucingo lwentsimbiisikrweqe.

Ukuze iintambo zikwazi ukumelana noxinzelelo lwe-radial, kusetyenziswa iteyipu yentsimbi ephindwe kabini enenkqubo yokugquma izithuba—oku kwaziwa ngokuba yintambo yentsimbi exhonyiweyo. Emva kokufakelwa iintambo, iiteyipu zentsimbi zijikeleziswa kumbindi wentambo, kulandele ukukhutshwa kweshelufu yeplastiki. Iimodeli zentambo ezisebenzisa olu lwakhiwo ziquka iintambo zokulawula ezifana ne-KVV22, iintambo zombane ezifana ne-VV22, kunye neentambo zonxibelelwano ezifana ne-SYV22, njl. Amanani amabini esiArabhu kuhlobo lwentambo abonisa oku kulandelayo: u-"2" wokuqala umele i-double steel tape armor; u-"2" wesibini umele ishelufu ye-PVC (Polyvinyl Chloride). Ukuba kusetyenziswa ishelufu ye-PE (Polyethylene), idijithi yesibini itshintshwa ibe ngu-"3". Iintambo zolu hlobo zihlala zisetyenziswa kwiindawo ezinoxinzelelo oluphezulu, ezifana neendawo zokuwela iindlela, iiplaza, iindawo ezisengozini yokungcangcazela ecaleni kwendlela okanye kwiindawo ezisecaleni kololiwe, kwaye zifanelekile ukungcwaba ngqo, iitonela, okanye ukufakwa kwee-conduit.

Ukunceda iintambo zikwazi ukumelana noxinzelelo oluphezulu lwe-axial, iintambo ezininzi zentsimbi ezinekhabhoni ephantsi zijikeleziswa nge-helical zijikeleze isiseko sentambo—oku kwaziwa ngokuba yintambo yentsimbi exhonyiweyo. Emva kokufakelwa kweentambo, iintambo zentsimbi zigqunywa ngepitch ethile kwaye ishedi ikhutshelwa phezu kwazo. Iintlobo zeentambo ezisebenzisa olu lwakhiwo ziquka iintambo zokulawula ezifana ne-KVV32, iintambo zamandla ezifana ne-VV32, kunye neentambo ze-coaxial ezifana ne-HOL33. Amanani amabini esiArabhu kwimodeli amele: eyokuqala "3" ibonisa i-steel wire armor; eyesibini "2" ibonisa ishedi ye-PVC, kwaye "3" ibonisa ishedi ye-PE. Olu hlobo lwentambo lusetyenziswa kakhulu ekufakelweni kwexesha elide okanye apho kukho ukuhla okukhulu okuthe nkqo.

Umsebenzi weeCables ezixhotyisiweyo

Iintambo ezixhotyisiweyo zibhekisa kwiintambo ezikhuselweyo lulwaleko lwesikrweqe sesinyithi. Injongo yokongeza isikrweqe ayikokwandisa amandla okuxinana nokucinezelwa kunye nokwandisa ukuqina koomatshini, kodwa ikwaphucula ukumelana nokuphazamiseka kwe-electromagnetic (EMI) ngokusebenzisa isikhuselo.

Izinto zokuzikhusela eziqhelekileyo ziquka iteyiphu yentsimbi, intambo yentsimbi, iteyiphu yealuminiyam, kunye netyhubhu yealuminiyam. Phakathi kwazo, iteyiphu yentsimbi kunye nentambo yentsimbi zinamandla aphezulu okungena kwimagnethi, zibonelela ngeziphumo ezilungileyo zokukhusela imagnethi, ngakumbi ezisebenzayo ekuphazamisekeni okuphantsi. Ezi zinto zivumela intambo ukuba igqunywe ngqo ngaphandle kwee-conduits, nto leyo eyenza ukuba ibe sisisombululo esingabizi kakhulu nesisetyenziswa kakhulu.

Umaleko wesikrweqe ungafakwa kuyo nayiphi na isakhiwo seentambo ukuphucula amandla oomatshini kunye nokumelana nokugqwala, okwenza ukuba ube yindawo efanelekileyo kwiindawo ezinokonakala koomatshini okanye kwiindawo ezinobungozi. Ungabekwa nangayiphi na indlela kwaye ufanelekile ngokukodwa ukungcwatywa ngokuthe ngqo kwiindawo ezinamatye. Ngamafutshane, iintambo ezixhonyiweyo ziintambo zombane ezenzelwe ukungcwatywa okanye ukusetyenziswa phantsi komhlaba. Kwiintambo zokuhambisa umbane, isikrweqe songeza amandla okuxinana nokucinezela, sikhusela intambo kwimikhosi yangaphandle, kwaye sikwanceda ekuchaseni umonakalo weempuku, sithintele ukuhlafuna isikrweqe esinokuphazamisa ukudluliselwa kombane. Iintambo ezixhonyiweyo zifuna irediyasi enkulu yokugoba, kwaye umaleko wesikrweqe ungabekwa phantsi ukuze ukhuseleke.

I-ONE WORLD Igxile kwizixhobo zeCable ezikumgangatho ophezulu

Sinikezela ngoluhlu olupheleleyo lwezinto zokuzikhusela—kuquka iteyiphu yentsimbi, ucingo lwentsimbi, kunye neteyiphu yealuminiyam—ezisetyenziswa kakhulu kwiintambo ze-fiber optic kunye nezombane ukhuseleko lwesakhiwo kunye nokusebenza okuphuculweyo.
