Kuzinhlelo zokusebenza zamandla kagesi aphezulu (HV), ukukhetha isokhethi yekhebula efanele kubalulekile ukuze kuqinisekiswe ukuphepha, ukwethembeka nokusebenza kahle. Njengoba kunezinketho eziningi emakethe, kungaba nzima ukunquma ukuthi iyiphi elungele izidingo zakho ezithile. Kule bhulogi, sizoxoxa ngokubaluleka kokukhetha isokhethi yekhebula eliphezulu elifanele futhi sigqamise izici ezibalulekile zomkhiqizo wekhwalithi ephezulu.
Enye yezinto ezibalulekile okufanele uzicabangele lapho ukhetha i-aisitsha sekhebula le-voltage ephezuluimpahla yayo. Imikhiqizo yekhwalithi ephezulu kufanele yenziwe ngezinto ezishisayo ze-thermoplastic ezinezilinganiso eziphakeme zokumelana nelangabi, njenge-UL94V-0. Lokhu kuqinisekisa ukuthi isokhethi ingakwazi ukumelana namazinga okushisa aphezulu ngaphandle kokuncibilika noma ukubamba umlilo, okubalulekile ekugcineni ukuphepha ekusetshenzisweni kwamandla kagesi aphezulu.
Esinye isici esibalulekile sekhwalithi ephezulu yamasokhethi ekhebula le-voltage ephezulu ukumelana nokufakwa kwe-insulation ephezulu, kukalwa ngama-ohms imitha (Ω/m). Imikhiqizo ene-insulation resistivity ephezulu (≥1015 Ω/m) ihlinzeka ngokufaka ugesi okuhle kakhulu, inciphisa ingcuphe ye-arcing kanye nokuqinisekisa ukusebenza okungaguquki ngokuhamba kwesikhathi.
Isokhethi yekhebula yekhwalithi ephezulu kufanele ibe nepuleti le-anode ye-aluminum ye-corona-free ngaphezu kwezinto ezibonakalayo nokumelana nokufakwa. Le ngxenye ibalulekile ekwehliseni i-corona kanye nokunciphisa ingcuphe yokukhishwa kukagesi engabangela ukungasebenzi kwemishini noma ngisho nomlilo noma ukuqhuma.
Esinye isici esibalulekile okufanele sicatshangelwe lapho ukhetha isokhethi yekhebula lamandla kagesi aphezulu yizinsiza ozikhethela zona njengamaringi e-brass thrust, ama-O-rings eraba ophawu lwamafutha kanye nama-flange ethusi ane-nickel-plated. Lezi zingxenye zinikeza ukuvikeleka okwengeziwe okungathuthukisa ukusebenza okuphelele nokuthembeka kwe-outlet.
Sengiphetha, ukubaluleka kokukhetha isokhethi yekhebula lamandla kagesi aphezulu angeke kugcizelelwe ngokweqile. Imikhiqizo yekhwalithi ephezulu eyenziwe ngezinto ze-thermoplastic ezinebanga eliphakeme lokubuyiswa komlilo kanye nokumelana nokushisa okuphezulu, ipuleti le-aluminum anode ye-corona-free, izesekeli zokuzikhethela ezifana ne-brass thrust ring, indandatho yerabha yophawu lwe-O-type, i-nickel-plated brass flange yokugcinwa Ukuphepha, ukwethembeka nokusebenza kahle kwezicelo zamandla kagesi aphezulu kubalulekile. Ngokucubungula ngokucophelela lezi zici ezibalulekile nokukhetha umkhiqizo ofanele izidingo zakho ezithile, ungaqinisekisa ukuthi isistimu yakho yamandla kagesi aphezulu izosebenza ngokuphepha nangempumelelo eminyakeni ezayo.
