Ngokuthuthuka kobuhlakani embonini yemikhumbi yomhlaba wonke, izintambo zamabhasi asemanzini zidlala indima ebaluleke kakhulu ekuxhumaneni kwedatha yemikhumbi kanye nezinhlelo zokuzenzakalela. Zixhumanisa izinzwa, abalawuli, kanye nama-actuator ngaphakathi kwemikhumbi, zisekela imisebenzi efana nokulawula okuzenzakalelayo, ukuqapha okude, kanye nokuphathwa kokusebenza kahle kwamandla.
Ukuze zivumelane nezimo zasolwandle ezinzima ezibonakala ngokufuthwa ngosawoti omningi, umswakama omningi, kanye nokuphazamiseka okukhulu kwe-electromagnetic, izintambo zamabhasi olwandle zamukela izinto ezikhethekile kanye nemiklamo yesakhiwo, zinikeza ukumelana nokugqwala, ukubambezeleka komlilo, ukusebenza okuphansi kwe-halogen-free, kanye nokuvikela okuhle kakhulu kwe-EMI ukuqinisekisa ukusebenza okuzinzile kwesikhathi eside. Lesi sihloko sigxile ekwakhiweni kwesakhiwo sezintambo zamabhasi olwandle.
Ukubuka Konke Okuyisisekelo Kwesakhiwo
1. Umqhubi
Izintambo zamabhasi asemanzini zivame ukusebenzisa ama-conductor ethusi aboshwe nge-stranded. Ama-conductor aboshwe nge-stranded aqinisekisa ukusebenza kahle kukagesi kanye nokuphila isikhathi eside kwemishini ngenkathi enza kube lula ukufakwa. Uma kuqhathaniswa nama-conductor ethusi angenalutho, ama-conductor ethusi aboshwe nge-stranded anikeza ukumelana okuphezulu nokugqwala kwe-salt spray.
Ukusetshenziswa kwezikhonkwane zethusi ezifakwe emathinini kusiza ekuthuthukiseni izinkinga ezifana nokunciphisa imvamisa ephezulu, ukukhathala okugobile, ukugqwala kwesifutho sikasawoti, ukuphuka kwezinga lokushisa eliphansi, kanye nendawo encane yokufaka, okwenza zifaneleke kakhulu ekusetshenzisweni kwekhebula lebhasi lasolwandle.
2. Ukuvikela
I-polyethylene enegwebu (i-Foam-PE)ivame ukusetshenziswa njengento yokuvikela izintambo zebhasi lasolwandle. Ukuvikela i-polyethylene ene-foam kunciphisa ngempumelelo i-dielectric constant, ngaleyo ndlela kunciphisa ukuncishiswa kwesignali, kuyilapho futhi kunikeza amandla okuvimba amanzi isikhathi eside. Ngaphezu kwalokho, ukusetshenziswa kwe-Foam-PE kusiza ukunciphisa isisindo sekhebula, okufaka isandla ekunciphiseni isisindo semikhumbi iyonke.
3. Ukuvikela
Isakhiwo sokuvikela izintambo zebhasi lasolwandle sifana nesezintambo zenethiwekhi yasolwandle futhi ngokuvamile siquketheiteyipu ye-aluminium ehlanganiswe ngepulasitikikuhlanganiswe nokuluka ucingo lwethusi olufakwe ethini. Isendlalelo sokuvikela senzelwe ukuvimba ukuphazamiseka kwe-electromagnetic nokuqinisekisa ukudluliswa kwesignali okuzinzile.
Ngokuvamile, ubukhulu be-aluminium foil bungu-≥ 0.012 mm ngokumbozwa okungu-100%, kuyilapho i-braid yethusi efakwe ethini ivame ukusebenzisa izintambo ezilodwa ezingu-0.12 mm, ngokumbozwa kwe-braid okungenani okungu-60%.
Ezimweni eziningi, izintambo zebhasi zasolwandle zisebenzisa isakhiwo esivikela kabili setheyiphu ye-aluminium eboshwe ngepulasitiki kanye nokuluka kwethusi okufakwe ethini. Lokhu kuvikela okuhlanganisiwe kungathuthukisa ukusebenza kahle kokuvikela kufike ku-70–90 dB @ 30 MHz.
Ngaphezu kwalokho, ucingo lokukhipha amanzi oluqinile noma oluboshwe ngethini luvame ukufakwa ukuze lunikeze isisekelo esengeziwe.
4. Umgodla
Isivikelo sisebenza ukuvikela ikhebula emathonyeni angaphandle emvelo. Njengomugqa wokuqala wokuzivikela, izinto zesivikelo sezintambo zebhasi zasolwandle kumele zinikeze ukumelana nokugqwala kwe-salt spray, ukuklwebheka, kanye nokusabalala komlilo ukuqinisekisa ukuthembeka nokuphepha ezimweni ezinzima.
Ukuze kuthuthukiswe ukuphepha kwezinhlelo zokuxhumana zebhodi lemikhumbi, izintambo zamabhasi olwandle zivame ukusebenzisa izinto zesheya ze-polyolefin (LSZH-SHF1) ezingenamusi ophansi we-halogen. Lezi zinto azikhiphi umusi onobuthi ngesikhathi sokusha futhi ziyahambisana ne-IEC 60332-1 single-cable flame retardancy, i-IEC 60332-3-22 bundled flame retardancy, kanye nezimfuneko ze-IEC 60754-1/2 kanye ne-IEC 61034-1/2 ezingenamusi ophansi we-halogen. Lokhu akugcini nje ngokunciphisa izingozi zokuphepha kwabasebenzi uma kwenzeka umlilo kodwa futhi kunciphisa nomthelela emvelweni.
Ezinkundleni zasogwini kanye nezinhlelo zokusebenza ezifanayo, izintambo zamabhasi olwandle zingadingeka futhi ukuze zibonise ukumelana nowoyela nodaka. Ezimweni ezinjalo, izinto ze-LSZH-SHF2 ezinokumelana nowoyela okuthuthukisiwe, noma izinto ze-LSZH-SHF2-MUD ezinokumelana nodaka okwengeziwe, zikhethwa emgodleni.
5. Izakhiwo Ezikhethekile
Ngaphansi kwezimo ezijwayelekile, isakhiwo sekhebula lebhasi lasolwandle esijwayelekile esiqukethe umqhubi, ukuvikela, isivikelo, kanye negobolondo sanele ukusetshenziswa okuningi kwasolwandle. Uma kufakwa izidingo zokusebenza eziphakeme, isakhiwo sekhebula singashintshwa ngokufanele.
Isibonelo, ezicelweni ezidinga ukuvikelwa okwengeziwe kwemishini, ungqimba lwezivikelo lungangezwa, kanye nesikhwama sangaphandle esengeziwe ukuze kwakhiwe isakhiwo esivikelo esinazo izigqoko ezimbili. Ungqimba lwezivikelo ngokuvamile lwenziwa ngensimbi eboshwe ngensimbi, okuthuthukisa kakhulu amandla emishini futhi kuvikele ikhebula ekulimaleni ezindaweni ezinzima.
Uma kusetshenziswa izintambo zebhasi lasolwandle ezisetshenziswayo ezingashi, ukugoqwa kwetheyiphu ye-mica kuyangezwa phezu kwesendlalelo sokuvikela umlilo ukuze kuhlangatshezwane nezindinganiso ze-IEC 60331 zokumelana nomlilo kanye nezidingo zokubuyela echwebeni ngokuphephile.
Isiphetho
Ukwakheka kwesakhiwo kanye nokukhethwa kwezinto zezintambo zamabhasi olwandle kuyizinto ezibalulekile ezivumela ukudluliswa kwesignali okuzinzile nokuthembekile ezindaweni zasolwandle ezinzima. Kungakhathaliseki ukuthi kungaba abaqhubi bethusi abafakwe emathinini, ukufakelwa kwe-polyethylene ene-foam, noma ama-sheath angenawo umusi ophansi we-halogen, lawa madizayini esakhiwo athuthukiswe kakhulu futhi athuthukiswa.
Izakhiwo zekhebula eziklanywe kahle ziqinisekisa ukusebenza okuqhubekayo nokuthembekile kwezintambo zebhasi lasolwandle ezindaweni zasolwandle lapho amazinga okushisa aphezulu, ukugqwala kwe-salt spray, kanye nokuphazamiseka okukhulu kwe-electromagnetic kuhambisana khona.
