Ngezinhlelo zokusebenza ze-high voltage (HV), ukukhetha isokhethi yekhebula efanele kubalulekile ekuqinisekiseni ukuphepha, ukuthembeka kanye nokusebenza kahle. Njengoba kunezinketho eziningi emakethe, kungaba nzima ukunquma ukuthi iyiphi engcono kakhulu ngezidingo zakho ezithile. Kule bhulogi, sizoxoxa ngokubaluleka kokukhetha isokhethi yekhebula ye-high voltage efanele futhi sigqamise izici ezibalulekile zomkhiqizo wekhwalithi ephezulu.
Esinye sezici ezibaluleke kakhulu okufanele uzicabangele lapho ukhethaisithako sekhebula le-voltage ephezuluiyimpahla yayo. Imikhiqizo esezingeni eliphezulu kufanele yenziwe ngezinto ze-thermoplastic ezinezilinganiso zokumelana nomlilo eziphezulu, njenge-UL94V-0. Lokhu kuqinisekisa ukuthi isokhethi ingamelana namazinga okushisa aphezulu ngaphandle kokuncibilika noma ukubamba umlilo, okubalulekile ekugcineni ukuphepha ekusetshenzisweni kwamandla kagesi aphezulu.
Esinye isici esibalulekile sama-cable sockets asezingeni eliphezulu angama-voltage ukumelana okuphezulu kokushisa, okulinganiswa ngama-ohms ngemitha (Ω/m). Imikhiqizo enokubekezelela okuphezulu kokushisa (≥1015 Ω/m) inikeza ukufudumala okuhle kakhulu kukagesi, okunciphisa ingozi yokuqina kwe-arcing nokuqinisekisa ukusebenza okuqhubekayo ngokuhamba kwesikhathi.
Isokhethi yekhebula elinamandla aphezulu esezingeni eliphezulu kufanele ibe nepuleti le-anode le-aluminium elingenayo i-corona ngaphezu kokumelana nezinto zokwakha kanye nokushisa. Le ngxenye ibalulekile ekunciphiseni i-corona nokunciphisa ingozi yokukhishwa kukagesi okungabangela ukwehluleka kwemishini noma ngisho nomlilo noma ukuqhuma.
Esinye isici esibalulekile okufanele usicabangele lapho ukhetha isokhethi yekhebula elinamandla aphezulu yizinto ozikhethela zona njengezinsimbi zokucindezela zethusi, izindandatho ze-O zerabha zezivalo zikawoyela kanye nama-flange ethusi afakwe i-nickel. Lezi zingxenye zinikeza isivikelo esengeziwe esingathuthukisa ukusebenza kanye nokuthembeka kwendawo yokukhipha.
Ekuphetheni, ukubaluleka kokukhetha isokhethi yekhebula le-high voltage efanele akunakugcizelelwa ngokweqile. Imikhiqizo esezingeni eliphezulu eyenziwe ngezinto ze-thermoplastic ezinezinga eliphezulu lokuvimbela umlilo kanye nokumelana okuphezulu kokushisa, ipuleti le-anode le-aluminium elingenayo i-corona, izesekeli ongazikhetha njengendandatho ye-brass thrust, indandatho yerabha ye-oil seal ye-O-type, i-nickel-plated brass flange yokulungisa Ukuphepha, ukuthembeka kanye nokusebenza kahle ekusetshenzisweni kwe-high voltage kubalulekile. Ngokucabanga ngokucophelela ngalezi zici ezibalulekile nokukhetha umkhiqizo ofanele izidingo zakho ezithile, ungaqinisekisa ukuthi uhlelo lwakho lwe-high voltage luzosebenza ngokuphepha nangokusebenza kahle iminyaka ezayo.
