Uma ukhetha izintambo nezintambo, ukuchaza ngokucacile izidingo nokugxila kukhwalithi kanye nemininingwane kubalulekile ekuqinisekiseni ukuphepha nokuqina. Okokuqala, uhlobo olufanele lwentambo kufanele lukhethwe ngokusekelwe esimweni sokusetshenziswa. Isibonelo, izintambo zasekhaya zivame ukusebenzisa izintambo ezifakwe i-PVC (Polyvinyl Chloride), kuyilapho izindawo zezimboni, ezingase zibe ngaphansi kwezimo ezinzima, zivame ukudinga izintambo ezinokumelana okukhulu nokushisa nokugqwala, njengalezo ezine-I-XLPE (i-Cross-Linked Polyethylene)Ukushisa. Ukusetshenziswa kwangaphandle, izintambo ezine-Aluminium Foil Mylar Tape njengezinto zokuvikela ziyathandwa ukuze kuthuthukiswe ukumelana nesimo sezulu kanye nokusebenza okungangeni manzi. Ngaphezu kwalokho, kubalulekile ukubala amandla omthwalo bese ukhetha imininingwane efanele yekhebula ngokusekelwe esilinganisweni samandla semishini kagesi, ukuqinisekisa ukuthi izinto zomqhubi, njengethusi elingenawo umoya-mpilo noma ithusi elifakwe ethini, zinokuqhuba okwanele ukuvimbela ukushisa ngokweqile noma ukungasebenzi kahle ngenxa yokugcwala ngokweqile.
Ngokuphathelene nekhwalithi yomkhiqizo, kuyalulekwa ukukhetha izintambo eziqinisekiswe yizinhlangano ezifana ne-CCC kanye ne-ISO 9001, ukuqinisekisa ukuthi ziyahlangabezana nezindinganiso zekhwalithi zikazwelonke. Ngaphezu kwalokho, izintambo zekhwalithi ephezulu kufanele zibe nokubukeka okubushelelezi, okuyindilinga okunombala ofanayo. Ingqimba yokushisa kufanele ingabi namabhamuza noma ukungcola futhi ibe nobukhulu obufanayo. Ngokuphathelene nezinto zomqhubi, izintambo zethusi kufanele zibe nsomi ngokubomvu, zibe nomphezulu ocwebezelayo kanye nezintambo ezisontekile, kanti izintambo ze-aluminium kufanele zibe mhlophe njengesiliva. Uma izintambo zethusi zibonakala zinsomi ngokumnyama noma ziqukethe ukungcola, zingase zenziwe ngezinto eziphansi, ngakho-ke kufanele kuqashelwe.
Uma ukhetha imininingwane yekhebula, indawo yesigaba esinqamulayo se-conductor kufanele icatshangelwe maqondana nomthamo womthwalo kanye nendawo yokusebenza. Isigaba esikhulu esinqamulayo se-conductor sivumela umthamo ophezulu wokuthwala ugesi kodwa kwandisa izindleko. Ngakho-ke, ukulinganisela kokubili ukonga nokuphepha kubalulekile. Ngaphezu kwalokho, inani lama-cores kufanele likhethwe ngokwezidingo zangempela: amasekethe esigaba esisodwa ngokuvamile asebenzisa izintambo ezimbili noma ezintathu, kuyilapho amasekethe esigaba ezintathu edinga izintambo ezintathu noma ezine. Ngokuhlola kahle isimo sokusetshenziswa kanye nezidingo zobuchwepheshe, izintambo ezikhethiwe zizoba zingabizi futhi zikwazi ukusebenza isikhathi eside.
Ezimweni ezikhethekile, njengezimo zokushisa okuphezulu, izintambo ezingamelani nokushisa okuphezulu, njengezintambo ezingamelani nomlilo ezineiteyipu ye-micaUkusonga noma izintambo ezivalekile ze-XLPE, kungagcina ukusebenza okuzinzile ezithandweni zezimboni noma ezindaweni zokusebenzela ezishisa kakhulu. Ezakhiweni eziphakeme kanye nezindawo zomphakathi lapho ukuphepha komlilo kuyinto eza kuqala khona, izintambo ezingamelani nomlilo, ezingamelani nomlilo, noma ezingenayo i-halogen ezivimbela umlilo ziyizinketho eziphephile. Lezi zintambo ngokuvamile zinezendlalelo ezikhethekile ezingamelani nomlilo noma zifaka amateyipu okuvimba amanzi ukunciphisa ingozi yokusabalala komlilo nokuthuthukisa ukuphepha.
Okokugcina, ukukhetha uhlobo lomkhiqizo olunedumela elihle kanye nomhlinzeki othembekile kubalulekile. Imikhiqizo eyaziwayo ivame ukuba nezinqubo zokukhiqiza eziqinile kanye nokulawulwa kwekhwalithi, okuqinisekisa ukusebenza okungcono futhi okunikeza insizakalo ephelele ngemuva kokuthengisa. Ukuthenga eziteshini ezisemthethweni, njengezimakethe ezinkulu zezinto zokwakha noma abasabalalisi abaqinisekisiwe, akugcini nje ngokuqinisekisa ubuqiniso bemikhiqizo kodwa futhi kuqinisekisa ukwesekwa ngesikhathi uma kwenzeka izinkinga. Kunconywa ukugwema ukuthenga emithonjeni engaqinisekisiwe ukuze uvimbele ukuthenga imikhiqizo engamanga noma engaphansi kwekhwalithi.
Ukukhetha izintambo nezintambo kuyinqubo ehlelekile edinga ukunakwa ngokucophelela esigabeni ngasinye, kusukela ezidingweni zesimo kanye nokusebenza kwezinto kuya kwikhwalithi yomkhiqizo kanye nedumela lomhlinzeki. Ukukhetha okufanele akugcini nje ngokuqinisekisa ukuphepha kodwa futhi kuthuthukisa kakhulu impilo yesevisi kanye nokusebenza kahle kwemikhiqizo.
