Kuzinhlelo zokusebenza ezinesivinini esikhulu, ukukhethwa kwezinto zocingo nezekhebula kudlala indima ebalulekile ekuqinisekiseni ukusebenza kahle nokuthembeka. Isidingo samazinga okudlulisa idatha asheshayo kanye nomkhawulokudonsa okhulayo sidinga ukucatshangelwa ngokucophelela kwezinto ezihlukahlukene lapho kukhethwa izinto ezifanele. Lesi sihloko sigqamisa izici ezibalulekile okufanele zicatshangelwe lapho kukhethwa izintambo ezinesivinini esiphezulu nezinto zekhebula, sinikeza imininingwane yokuthi izinto ezifanele zingathuthukisa kanjani ubuqotho besignali, ukunciphisa ukulahlekelwa kwesignali, nokuqinisekisa ukudluliswa kwedatha okuphumelelayo.
Ubuqotho Besiginali kanye Nokuncipha
Ukugcina ubuqotho besignali kubalulekile ezinhlelweni zokusebenza ezinesivinini esikhulu. Izintambo ezikhethiwe kanye nezinto zekhebula kufanele zibonise ukuncishiswa kwesignali ephansi, kunciphise ukulahlekelwa amandla esignali ngesikhathi sokudlulisa. Izinto ezine-dielectric engaguquki kanye ne-tangent yokulahlekelwa, njenge-high-density polyethylene (HDPE) noma i-polytetrafluoroethylene (PTFE), zisiza ukulondoloza ikhwalithi yesignali, ukunciphisa ukuhlanekezela, nokuqinisekisa ukudluliswa kwedatha okunembile ebangeni elide.
I-Impedans Control
Ukulawulwa kwe-impedance okunembile kubalulekile ezinhlelweni zokuxhumana ezinesivinini esikhulu. Izinto zocingo nezekhebula kufanele zibe nezakhiwo zikagesi ezingaguquki ukuze kugcinwe i-impedance yesici esifanayo. Lokhu kuqinisekisa ukusakazwa kwesignali okufanele, kunciphisa ukubonakaliswa kwesignali, futhi kunciphisa ingozi yamaphutha edatha noma ukuwohloka kwesignali. Ukukhetha izinto ezinokubekezelela okuqinile nezici zikagesi ezizinzile, njenge-polyolefin enegwebu noma i-fluorinated ethylene propylene (FEP), kusiza ukufeza ukulawulwa okuqondile kwe-impedance.
Ukunciphisa i-Crosstalk kanye ne-EMI
Intambo enesivinini esiphezulu nekhebula kusengozini yokuphazanyiswa yi-crosstalk kanye ne-electromagnetic interference (EMI). Ukukhetha izinto ezifanele kungasiza ekwehliseni lezi zinkinga. Izinto zokuvikela, ezifana ne-aluminium foil noma izihlangu zethusi ezilukiwe, zinikeza isivikelo esisebenzayo ku-EMI yangaphandle. Ukwengeza, izinto ezisetshenziswayo ezine-crosstalk ephansi, ezifana nokulungiselelwa kokupheya okusontiwe noma izinto zokwakha ezinamajiyometri okuvikela athuthukisiwe, zisiza ukunciphisa ukuhlangana kwesignali okungafunwa futhi kuthuthukise ubuqotho besignali iyonke.
Ukucatshangelwa Kwemvelo
Izimo zokusebenza kanye nezici zemvelo kufanele zicatshangelwe lapho kukhethwa izintambo ezinesivinini esikhulu kanye nezinto zekhebula. Ukwehluka kwezinga lokushisa, umswakama, amakhemikhali, kanye nokuchayeka kwe-UV kungaba nomthelela ekusebenzeni kokubalulekile nokuphila isikhathi eside. Izinto ezinokuzinza okuhle kakhulu kokushisa, ukumelana nomswakama, ukumelana namakhemikhali, nokumelana ne-UV, njenge-polyethylene exhunywe ngokuphambana (XLPE) noma i-polyvinyl chloride (PVC), kuvame ukuthandwa kakhulu ukuze kuqinisekiswe ukusebenza okuthembekile ngaphansi kwezimo ezihlukahlukene zemvelo.
Ukukhetha izintambo ezifanele zejubane eliphezulu nezinto zekhebula kubalulekile ukuze kuzuzwe ukusebenza okuphezulu, ubuqotho besignali, nokwethembeka. Ukucatshangelwa okufana nokuncishiswa kwesignali, ukulawulwa kwe-impedance, ukwehlisa i-crosstalk kanye ne-EMI, kanye nezici zemvelo kubalulekile lapho wenza ukukhetha kwezinto ezibonakalayo. Ngokuhlola ngokucophelela lezi zici nokukhetha izinto ezinezici ezifanele zikagesi, ezomshini, nezemvelo, abakhiqizi bangahlangabezana nezidingo zezinhlelo zokusebenza ezinesivinini esikhulu futhi baqinisekise ukudluliswa kwedatha okuphumelelayo nokunokwethenjelwa.
