Ezinhlelweni zokusebenza ngesivinini esikhulu, ukukhethwa kwezinto zocingo nezekhebula kudlala indima ebalulekile ekuqinisekiseni ukusebenza kahle kanye nokuthembeka. Isidingo samazinga okudlulisa idatha ngokushesha kanye nokwanda komkhawulokudonsa kudinga ukucatshangelwa ngokucophelela izici ezahlukahlukene lapho kukhethwa izinto ezifanele. Lesi sihloko siqokomisa izici ezibalulekile okufanele zicatshangelwe lapho kukhethwa izinto zocingo nezekhebula zesivinini esikhulu, sinikeza ukuqonda kokuthi izinto ezifanele zingathuthukisa kanjani ubuqotho besiginali, zinciphise ukulahleka kwesiginali, futhi ziqinisekise ukudluliswa kwedatha okuphumelelayo.
Ubuqotho kanye nokuncishiswa kwesignali
Ukugcina ubuqotho besiginali kubalulekile ekusetshenzisweni kwesivinini esikhulu. Izinto ezikhethiwe zocingo kanye nekhebula kufanele zibonise ukuncishiswa kwesiginali okuphansi, kunciphise ukulahleka kwamandla esiginali ngesikhathi sokudlulisa. Izinto ezine-dielectric constant ephansi kanye ne-tangent yokulahleka, njenge-polyethylene ephezulu (HDPE) noma i-polytetrafluoroethylene (PTFE), zisiza ekulondolozeni ikhwalithi yesiginali, zinciphise ukuphambuka, futhi ziqinisekise ukudluliswa kwedatha okunembile emabangeni amade.
Ukulawulwa Kokuvinjelwa
Ukulawulwa okunembile kwe-impedance kubalulekile ezinhlelweni zokuxhumana ezisheshayo. Izinto zentambo nekhebula kufanele zibe nezakhiwo zikagesi ezihambisanayo ukuze kugcinwe i-impedance efanayo. Lokhu kuqinisekisa ukusabalala kwesignali okufanele, kunciphisa ukubonakaliswa kwesignali, futhi kunciphisa ingozi yamaphutha edatha noma ukuwohloka kwesignali. Ukukhetha izinto ezinokubekezelelana okuqinile kanye nezici zikagesi ezizinzile, njenge-polyolefin ene-foam noma i-ethylene propylene ene-fluorinated (FEP), kusiza ekufinyeleleni ukulawulwa kwe-impedance okunembile.
Ukunciphisa i-Crosstalk kanye ne-EMI
Intambo nekhebula ezisheshayo zisengozini yokukhuluma nge-crosstalk kanye nokuphazamiseka kwe-electromagnetic (EMI). Ukukhetha izinto ezifanele kungasiza ekunciphiseni lezi zinkinga. Izinto zokuvikela, njenge-aluminium foil noma izihlangu zethusi ezilukiwe, zinikeza isivikelo esisebenzayo ngokumelene ne-EMI yangaphandle. Ngaphezu kwalokho, izinto ezine-crosstalk ephansi, njengezilungiselelo ze-twisted pair noma izinto ezine-geometries yokushisa ethuthukisiwe, zisiza ekunciphiseni ukuhlanganiswa kwesignali okungafuneki futhi zithuthukise ubuqotho besignali iyonke.
Izinto Ezicatshangelwayo Ngezemvelo
Izimo zokusebenza kanye nezici zemvelo kumele zicatshangelwe lapho kukhethwa izinto zentambo nekhebula ezisheshayo. Ukwehluka kwezinga lokushisa, umswakama, amakhemikhali, kanye nokuvezwa yi-UV kungathinta ukusebenza kwezinto kanye nokuphila isikhathi eside. Izinto ezinokuzinza okuhle kakhulu kokushisa, ukumelana nomswakama, ukumelana namakhemikhali, kanye nokumelana ne-UV, njenge-polyethylene exhumene (XLPE) noma i-polyvinyl chloride (PVC), zivame ukuthandwa ukuqinisekisa ukusebenza okuthembekile ngaphansi kwezimo zemvelo ezahlukahlukene.
Ukukhetha izinto ezifanele zentambo nekhebula ezinesivinini esikhulu kubalulekile ekufezeni ukusebenza kahle, ubuqotho besignali, kanye nokuthembeka. Izinto okufanele zicatshangelwe njengokuncishiswa kwesignali, ukulawulwa kokungavimbeli, ukuncishiswa kwe-crosstalk kanye ne-EMI, kanye nezici zemvelo zibalulekile lapho kwenziwa ukukhetha izinto ezibonakalayo. Ngokuhlola ngokucophelela lezi zici nokukhetha izinto ezinezakhiwo zikagesi, zemishini, nezendawo ezifanelekile, abakhiqizi bangahlangabezana nezidingo zezinhlelo zokusebenza ezinesivinini esikhulu futhi baqinisekise ukudluliswa kwedatha okusebenzayo nokuthembekile.
