Ngophuhliso lobuchwephesha kwishishini lokuthumela ngenqanawa kwihlabathi liphela, iintambo zebhasi zasemanzini zidlala indima ebaluleke ngakumbi kwiinkqubo zonxibelelwano lwedatha yebhodi yenqanawa kunye ne-automation. Ziqhagamshela ii-sensors, abalawuli, kunye nee-actuators ngaphakathi kweenqanawa, zixhasa imisebenzi efana nolawulo oluzenzekelayo, ukujonga kude, kunye nolawulo lokusebenzisa amandla ngokufanelekileyo.
Ukuze zilungelelane neendawo ezirhabaxa zaselwandle eziphawulwa kukutshiza ngetyuwa eninzi, ukufuma okuphezulu, kunye nokuphazamiseka okunamandla kwe-electromagnetic, iintambo zebhasi zaselwandle zamkela izixhobo ezikhethekileyo kunye noyilo lwesakhiwo, zibonelela ngokumelana nokugqwala, ukubambezeleka komlilo, ukusebenza okuphantsi kwe-halogen yomsi, kunye nokukhusela i-EMI ukuqinisekisa ukusebenza okuzinzileyo ixesha elide. Eli nqaku ligxile kuyilo lwesakhiwo seentambo zebhasi zaselwandle.
Isishwankathelo seSiseko seSakhiwo
1. Umqhubi
Iintambo zebhasi zasemanzini zihlala zisebenzisa ii-conductors zekotoni ezixineneyo. Ii-conductors ezixineneyo ziqinisekisa ukusebenza kakuhle kombane kunye nobomi boomatshini ngelixa zisenza kube lula ukufakwa. Xa kuthelekiswa nee-conductors zekotoni ezingenanto, ii-conductors zekotoni ezixineneyo zibonelela ngokumelana okuphezulu nokugqwala kwetyuwa.
Ukusetyenziswa kwee-copper conductors ezifakwe kwi-tink kunceda ukuphucula imiba efana nokunciphisa i-high-frequency, ukudinwa okugobileyo, ukugqwala kwe-salt spray, ukubuthathaka kobushushu obuphantsi, kunye nendawo encinci yokufaka, okwenza ukuba zifaneleke kakhulu kwiintambo zebhasi zasemanzini.
2. Ukuvala ubushushu
I-polyethylene enegwebu (i-Foam-PE)Isetyenziswa kakhulu njengesixhobo sokukhusela iintambo zebhasi zasemanzini. Ukukhusela iintambo ze-polyethylene ezinefoam kunciphisa ngokufanelekileyo i-dielectric constant, ngaloo ndlela kunciphisa ukuncitshiswa kwesignali, ngelixa kubonelela nangobuchule bokuthintela amanzi obude. Ukongeza, ukusetyenziswa kwe-Foam-PE kunceda ukunciphisa ubunzima beentambo, okufaka isandla ekunciphiseni ubunzima beentambo ngokubanzi.
3. Ukukhusela
Ulwakhiwo lokukhusela iintambo zebhasi zasemanzini lufana nolweentambo zenethiwekhi zasemanzini kwaye ngokubanzi luqukaiteyiphu ye-aluminium egqunywe ngeplastikiidityaniswe nokuluka ucingo lwekopolo olufakwe kwitini. Umaleko wokukhusela wenzelwe ukuthintela ukuphazamiseka kwe-electromagnetic nokuqinisekisa ukuhanjiswa kwesignali okuzinzileyo.
Ngokwesiqhelo, ubukhulu befoyile ye-aluminiyam buyi-≥ 0.012 mm kunye nokugqunywa kwe-100%, ngelixa ukugqunywa kwethusi okufakwe kwi-tin kudla ngokusebenzisa iingcingo ezi-0.12 mm, kunye nokugqunywa kwe-braid ubuncinane obuyi-60%.
Kwiimeko ezininzi, iintambo zebhasi zasemanzini zisebenzisa isakhiwo esikhusela kabini seteyiphu ye-aluminiyam egqunywe ngeplastiki kunye ne-copper braid efakwe kwi-tin. Olu khuselo oluhlanganisiweyo lunokuphucula ukusebenza kakuhle kokhuselo ukuya kwi-70–90 dB @ 30 MHz.
Ukongeza, ucingo lokukhupha ubhedu oluqinileyo okanye oluxineneyo ludla ngokufakwa ukuze lubonelele ngesiseko esongezelelweyo.
4. Isingxobo
Isingxobo sisebenza ekukhuseleni intambo kwiimpembelelo zangaphandle kokusingqongileyo. Njengomgca wokuqala wokuzikhusela, izinto zesingxobo zeentambo zebhasi zasemanzini kufuneka zinike ukumelana nokugqwala kwetyuwa, ukukrala, kunye nokwanda komlilo ukuqinisekisa ukuthembeka nokhuseleko kwiimeko ezinzima.
Ukuphucula ukhuseleko lweenkqubo zonxibelelwano lwebhodi yenqanawa, iintambo zebhasi zasemanzini zihlala zisebenzisa izixhobo zesheya ze-polyolefin (LSZH-SHF1) ezingenamsi uphantsi. Ezi zinto azikhuphi umsi onobuthi ngexesha lokutsha kwaye ziyahambelana ne-IEC 60332-1 single-cable flame retardancy, i-IEC 60332-3-22 bundled flame retardancy, kunye neemfuno ze-IEC 60754-1/2 kunye ne-IEC 61034-1/2 ezingenamsi uphantsi. Oku akunciphisi nje kuphela iingozi kukhuseleko lwabasebenzi xa kutsha kodwa kukwanciphisa nempembelelo kwindalo esingqongileyo.
Kwiiplatfomu zaselwandle nakwiindawo ezifanayo, iintambo zebhasi zaselwandle zinokufuneka ukuze kuboniswe ukumelana neoyile nodaka. Kwiimeko ezinjalo, izinto ze-LSZH-SHF2 ezinokumelana neoyile ephuculweyo, okanye izinto ze-LSZH-SHF2-MUD ezinokumelana nodaka olongezelelweyo, zikhethwa kwishelufu.
5. Izakhiwo ezikhethekileyo
Phantsi kweemeko eziqhelekileyo, isakhiwo sekhebula lebhasi yolwandle esiqhelekileyo esiquka umqhubi, ubushushu, isikhuselo, kunye nesheya sanele ukusetyenziswa kakhulu kolwandle. Xa kumiselwa iimfuno zokusebenza eziphezulu, isakhiwo sekhebula sinokuguqulwa ngokufanelekileyo.
Umzekelo, kwizicelo ezifuna ukhuseleko olongezelelweyo loomatshini, kunokongezwa umaleko wezixhobo, kunye neshedi yangaphandle eyongezelelweyo ukwenza isakhiwo sezixhobo esinezigqubuthelo ezimbini. Umaleko wezixhobo uhlala wenziwe ngentsimbi eqinisiweyo, eyonyusa kakhulu amandla oomatshini kwaye ikhusela intambo ekonakaleni kwiindawo ezinzima.
Xa kusetyenziswa iintambo zebhasi zasemanzini kwiindawo ezingatshiyo, i-mica tape wrapping yongezwa phezu komaleko wokugquma ukuze ihlangabezane nemigangatho ye-IEC 60331 yokumelana nomlilo kunye neemfuno zokubuyela kwizibuko ngokukhuselekileyo.
Isiphelo
Uyilo lwesakhiwo kunye nokukhethwa kwezinto ezisetyenziswa kwiintambo zebhasi zasemanzini zizinto eziphambili ezivumela ukuhanjiswa kwesignali okuzinzileyo nokuthembekileyo kwiindawo zaselwandle ezinzima. Nokuba zii-copper copper conductors, i-foam polyethylene insulation, okanye ii-sheaths ezithintela umlilo ezingenamsi omninzi, ezi zakhiwo ziye zaphuculwa kakhulu kwaye zaphuculwa.
Izakhiwo zeentambo ezicwangciswe kakuhle ziqinisekisa ukusebenza okuqhubekayo nokuthembekileyo kweentambo zebhasi zaselwandle kwiindawo zaselwandle apho kukho amaqondo obushushu aphezulu, ukugqwala kwetyuwa, kunye nokuphazamiseka okunamandla kwe-electromagnetic.
