Intambo Ephindwe kabini
Intambo ekhuselweyo kabini luhlobo olukhethekileyo lwentambo yombane eyenziwe ngobunono ukuze inikeze ukhuseleko oluphezulu ngokuchasene nokuphazamiseka kwe-electromagnetic (EMI) kunye nokuphazamiseka kwamaza kanomathotholo (RFI). Ibandakanya imigangatho emibini eyahlukeneyo yokhuselo -ngokuqhelekileyo indibaniselwano echanekileyo ye -aluminium foil kunye ne-copper braid -esebenzisana ngokubambisana ukuqinisekisa ukuhanjiswa kwesignali ecocekileyo, ethembekileyo, ezinzileyo nakwiimeko ezinzima.
Ezi ntambo zisetyenziswa ngokubanzi kwiindawo eziphakamileyo apho ingxolo yombane enamandla okanye ukuphazamiseka komqondiso kunokuphazamisa kakhulu ukusebenza, kubandakanywa ne -industrial automation systems , amaziko edatha ye , -CNC oomatshini , kunye nezinye izicelo ezichanekileyo.
Kutheni Ukukhuselwa kabini kubalulekile
Iintambo ezinokhuselo olulodwa ziyakwazi ukulawula ukuphazamiseka okusisiseko kwimimiselo ephantsi, kodwa ukukhusela kabini kuphakamisa ukhuseleko kwinqanaba elitsha ngokupheleleyo lokuthembeka kunye nokusebenza.
Umaleko wokuqala wekhaka -ngokuqhelekileyo icwecwe elibhityileyo, eliqhuba kakhulu i-aluminiyam -ithintela ngokufanelekileyo ingxolo ye-electromagnetic yangaphandle evela kwimithombo efana neentambo zamandla, iimoto, okanye iimpawu ezingenazingcingo. Ngeli xesha, umaleko wesibini , oqhele ukuba olulukiweyo ngokuqinileyo yintsimbi yobhedu , usebenza ngeenjongo ezimbini: unciphisa ukuhlangana kwangaphakathi phakathi kwabaqhubi abasondeleyo ngaphakathi kwentambo kwaye iphakamisa kakhulu ukuqina komatshini kunye nokuguquguquka phantsi koxinzelelo.
Olu yilo lwe-synergistic-layer-layer luqinisekisa ukuhambelana, umgangatho wesignali ephezulu yengqibelelo , nakwizicelo ze-high-frequency okanye iindawo ezinomatshini onzima apho ukungcangcazela, ingxolo yombane, kunye nokunxiba komzimba kuyimingeni eqhubekayo.
Njengoko iinkqubo zombane zikhula ngokuntsonkotha kwaye zipakishwe ngokuxineneyo-kunye namazinga aphezulu edatha, izinzwa ezibuthathaka, kunye nezixhobo ezidityanisiweyo- imfuno yeentambo ezikhuselwe kabini ziye zangena kuwo wonke umzi-mveliso, unxibelelwano, izixhobo zonyango, i-aerospace, kunye neziseko zedatha , zibenza zibe yimfuneko ekuthembekeni okubaluleke kakhulu.
Ubume beCable Shielded Cable
Intambo eqhelekileyo ekhuselweyo ephindwe kabini yenziwe ngobunjineli obuchanekileyo, ulwakhiwo olunamaleko amaninzi ukwandisa imfezeko yomqondiso kunye nokuqina. Amacandelo ayo aquka:
1. Umqhubi
Undoqo udla ngobhedu oluphezulu (oluqilima okanye olunqatyisiweyo) ukuqinisekisa ukuhanjiswa kombane okusebenzayo kunye nokulahleka komqondiso omncinci kumgama.
2. I-Insulation
Umaleko we-dielectric-ngokuqhelekileyo i-PVC, i-PE, okanye i-FEP -ijikeleze umqhubi ngamnye, ukuthintela imijikelezo emfutshane , ukunciphisa i-capacitance, kunye nokugcina intembeko yesignali engaguqukiyo..
3. Ikhaka lokuqala
Ngokuqhelekileyo ifoyile ye-aluminiyam (ehlala ixhaswa yi-polyester), lo maleko ubonelela nge-100% yokhuselo ukubhloka ngokufanelekileyo uphazamiseko lwe-high-frequency electromagnetic (EMI) kwimithombo yangaphandle.
4. Ikhaka lesibini
Ubhedu olulukiweyo olulukiweyo olulukiweyo olulukiweyo okanye umnatha wobhedu owenziwe ngetinki (olune-65-95% yokugubungela) olufunxa ingxolo ye-frequency ephantsi , kunciphisa i-crosstalk yangaphakathi , kwaye yongeza amandla omatshini kunye nokuguquguquka ukugoba ngokuphindaphindiweyo okanye ukungcangcazela.
5. Ibhatyi yangaphandle
I-sheath enqabileyo, i-flame-retardant, i-UV-resistant, kunye ne-oyile-resistant sheath (efana ne -PVC, i-TPE, okanye i-LSZH ) ekhusela ukushisa, ukufuma, ukukrazula, iikhemikhali, kunye nomonakalo womzimba , ukuqinisekisa ukuthembeka kwexesha elide kwiindawo ezinzima.
Olu lwakhiwo lunobunkunkqele lolwakhiwo alukhulisanga nje ukwaliwa kwe-EMI/RFI kodwa luqinisekisa ubomi obude bokusebenza kunye nokusebenza okungaguquguqukiyo , naphantsi koxinzelelo olugqithisileyo kushishino okanye kokusingqongileyo.
Umahluko oPhambili kwiCable-Shielded Cable
Iintambo ezinokhuselo olulodwa zisebenzisa umaleko omnye (ngokuqhelekileyo i-foil okanye i-braid) kukhuseleko olusisiseko lwe-EMI, olufanelekileyo kwisethingi yengxolo ephantsi njengeenkqubo zomsindo okanye imigca yedatha yomgama omfutshane. Iintambo ezikhuselwe kabini, nangona kunjalo, zibandakanya iileya ezimbini- zihlala zidibanisa i-foil kunye ne-braid-ukuphucula ukusebenza. Nalu uthelekiso olukhawulezayo:
