M'mapulogalamu othamanga kwambiri, kusankha kwa waya ndi zida za chingwe kumakhala ndi gawo lofunikira pakuwonetsetsa kuti magwiridwe antchito ndi odalirika. Kufunika kwamitengo yotumizira mwachangu komanso kuchuluka kwa bandiwifi kumafuna kulingalira mosamala zinthu zosiyanasiyana posankha zida zoyenera. Nkhaniyi ikuwonetsa zinthu zofunika kuziganizira posankha mawaya othamanga kwambiri ndi zida za chingwe, kupereka zidziwitso za momwe zida zoyenera zingathandizire kukhulupirika kwazizindikiro, kuchepetsa kutayika kwa ma siginecha, ndikuwonetsetsa kutumiza kwa data moyenera.
Kukhulupirika kwa Signal ndi Kuchepetsa
Kusunga umphumphu wa chizindikiro ndikofunikira pamapulogalamu othamanga kwambiri. Waya wosankhidwa ndi zida za chingwe ziyenera kuwonetsa kutsika kwa siginecha, kuchepetsa kutayika kwa mphamvu yazizindikiro pakutumiza. Zipangizo zokhala ndi dielectric yochepa nthawi zonse komanso kutaya tangent, monga high-density polyethylene (HDPE) kapena polytetrafluoroethylene (PTFE), zimathandiza kusunga khalidwe lachidziwitso, kuchepetsa kupotoza, ndikuonetsetsa kuti deta yolondola imatumizidwa pamtunda wautali.
Kuwongolera kwa Impedans
Kuwongolera kolondola kwa impedance ndikofunikira pamakina olumikizirana othamanga kwambiri. Waya ndi chingwe zinthu zimayenera kukhala ndi mphamvu zamagetsi zosasinthika kuti zikhalebe ndi mawonekedwe ofanana. Izi zimatsimikizira kufalikira koyenera kwa ma siginecha, zimachepetsa zowunikira, komanso zimachepetsa chiopsezo cha zolakwika za data kapena kuwonongeka kwa ma sign. Kusankha zida zololera molimba komanso mawonekedwe okhazikika amagetsi, monga polyolefin ya foamed kapena fluorinated ethylene propylene (FEP), kumathandiza kukwaniritsa kuwongolera koyenera.
Crosstalk ndi EMI Mitigation
Waya wothamanga kwambiri ndi chingwe amatha kusokoneza crosstalk ndi electromagnetic interference (EMI). Kusankha zinthu moyenera kungathandize kuchepetsa mavutowa. Zida zotchingira, monga zojambula za aluminiyamu kapena zishango zamkuwa zolukidwa, zimapereka chitetezo chokwanira ku EMI yakunja. Kuphatikiza apo, zida zokhala ndi ma crosstalk otsika, monga masinthidwe opindika kapena zida zokhala ndi ma geometries okongoletsedwa bwino, zimathandizira kuchepetsa kulumikizana kosafunikira ndikusintha kukhulupirika kwa ma siginecha.
Kuganizira Zachilengedwe
Mikhalidwe yogwirira ntchito ndi zinthu zachilengedwe ziyenera kuganiziridwa posankha mawaya othamanga kwambiri ndi zipangizo zamagetsi. Kusiyanasiyana kwa kutentha, chinyezi, mankhwala, ndi kuwonekera kwa UV kungakhudze magwiridwe antchito ndi moyo wautali. Zida zomwe zimakhala ndi kukhazikika kwamafuta, kukana chinyezi, kukana kwa mankhwala, komanso kukana kwa UV, monga polyethylene yolumikizidwa (XLPE) kapena polyvinyl chloride (PVC), nthawi zambiri zimakondedwa kuti zitsimikizire kugwira ntchito modalirika pansi pazikhalidwe zosiyanasiyana.
Kusankha mawaya othamanga kwambiri ndi zida za chingwe ndikofunikira kuti mukwaniritse bwino ntchito, kukhulupirika kwa ma sign, komanso kudalirika. Zolingalira monga kuchepetsedwa kwa ma sign, control impedance, crosstalk ndi EMI kuchepetsa, ndi zinthu zachilengedwe ndizofunikira popanga zisankho. Powunika mosamala mbali izi ndikusankha zida zokhala ndi mphamvu zamagetsi, zamakina, ndi chilengedwe, opanga amatha kukwaniritsa zomwe amafuna pakugwiritsa ntchito mwachangu ndikuwonetsetsa kuti kutumizidwa kwa data koyenera komanso kodalirika.
