Xa ukhetha iintambo kunye neengcingo, ukucacisa ngokucacileyo iimfuno kunye nokugxila kumgangatho kunye neenkcukacha zingundoqo ekuqinisekiseni ukhuseleko kunye nokuqina. Okokuqala, uhlobo olufanelekileyo lwentambo kufuneka lukhethwe ngokusekelwe kwimeko yokusetyenziswa. Umzekelo, iintambo zasendlini zisebenzisa iPVC (Polyvinyl Chloride) iintambo ezigqunyiweyo, ngelixa iindawo zemizi-mveliso, ezinokuthi zibe phantsi kweemeko ezirhabaxa, zihlala zifuna iintambo ezinokumelana okuphezulu nobushushu kunye nomhlwa, njengezoI-XLPE (iPolyethylene eQhagamshelweyo)ukugquma. Ukusetyenziswa kwangaphandle, iintambo ezine-Aluminium Foil Mylar Tape njengezinto ezikhuselayo zikhethwa ukwandisa ukumelana nemozulu kunye nokusebenza kokungena kwamanzi. Ukongezelela, kubalulekile ukubala umthamo wangoku kwaye ukhethe inkcazo yekhebula efanelekileyo esekelwe kumlinganiselo wamandla wezixhobo zombane, ukuqinisekisa ukuba izinto ze-conductor, ezifana ne-oxygen-free copper okanye i-copper e-tinned, ine-conductivity eyaneleyo yokukhusela ukushisa okanye ukungasebenzi kakuhle ngenxa yokugqithisa.
Ngokumalunga nomgangatho wemveliso, kuyacetyiswa ukuba ukhethe iintambo eziqinisekisiweyo yimibutho efana neCCC kunye ne-ISO 9001, ukuqinisekisa ukuba ziyahlangabezana nemigangatho yelizwe. Ngaphaya koko, iintambo zomgangatho ophezulu kufuneka zibe nenkangeleko egudileyo, engqukuva enombala ofanayo. Umaleko wokugquma kufuneka ukhululeke kumaqamza okanye ukungcola kwaye ube nobukhulu obuhambelanayo. Ngokubhekiselele kwizinto zomqhubi, ii-conductors zobhedu kufuneka zibe nobomvu-mfusa, kunye nomphezulu okhanyayo kunye neentambo eziqiniweyo, ngelixa abaqhubi be-aluminium kufuneka babe yisilivere-mhlophe. Ukuba iiconductors zobhedu zibonakala zimfusa-mnyama okanye ziqulethe ukungcola, zinokuthi zenziwe kwizinto eziphantsi, ngoko kufuneka kuqatshelwe.
Xa ukhetha ukucaciswa kwekhebula, i-conductor cross-sectional area kufuneka ithathelwe ingqalelo ngokumalunga nomthwalo wangoku kunye nendawo yokusebenza. I-conductor cross-section enkulu ivumela umthamo ophezulu wokuthwala okwangoku kodwa ukwandisa iindleko. Ngoko ke, ukulungelelanisa zombini uqoqosho kunye nokhuseleko kubalulekile. Ukongezelela, inani lee-cores kufuneka likhethwe ngokweemfuno zangempela: iisekethe zesigaba esisodwa ngokuqhelekileyo zisebenzisa iintambo ezimbini okanye ezintathu, ngelixa iisekethe ezithathu zifuna iintambo ezintathu okanye ezine. Ngokuphonononga ngokucokisekileyo imeko yokusetyenziswa kunye neemfuno zobugcisa, iintambo ezikhethiweyo ziya kuba zombini iindleko kwaye zikwazi ukusebenza ngokuthembekileyo ixesha elide.
Kwiimeko ezikhethekileyo, ezinje ngeendawo ezinobushushu obuphezulu, iintambo ezikwaziyo ukumelana nobushushu obuphezulu, njengeentambo ezikwaziyo ukumelana nomlilo.mica tapeukusonga okanye i-XLPE i-insulated cables, inokugcina ukusebenza okuzinzile kwiziko zoshishino okanye iiworkshops eziphezulu zokushisa. Kwizakhiwo eziphakamileyo kunye neendawo zoluntu apho ukhuseleko lomlilo luyiprayorithi, ukunqanda umlilo, ukunqandwa komlilo, okanye i-halogen-free-flame-retardant cables zikhetho ezikhuselekileyo. Ezi ntambo zidla ngokuba nezaleko ezikhethekileyo ezikwaziyo ukumelana nomlilo okanye ziquka iiteyiphu zokuvala amanzi ukunciphisa umngcipheko wokusasazeka komlilo kunye nokomeleza ukhuseleko.
Ekugqibeleni, ukukhetha uphawu oluthembekileyo kunye nomthengisi othembekileyo kubalulekile. Iibrendi ezaziwayo ngokuqhelekileyo zineenkqubo zokuvelisa ezingqongqo kunye nolawulo lomgangatho, ziqinisekisa ukusebenza ngcono kunye nokubonelela ngenkonzo ebanzi emva kokuthengisa. Ukuthenga kumajelo asemthethweni, afana neemarike ezinkulu zemathiriyeli yokwakha okanye abasasazi abaqinisekisiweyo, akuqinisekisi nje kuphela ukunyaniseka kweemveliso kodwa kukwaqinisekisa inkxaso ngexesha elifanelekileyo xa kukho imiba. Kuyacetyiswa ukuba uphephe ukuthenga kwimithombo engaqinisekiswanga ukuthintela ukuthenga izinto zomgunyathi okanye iimveliso ezingekho mgangathweni.
Ukukhetha iintambo kunye neengcingo yinkqubo ecwangcisiweyo efuna ukuqwalaselwa ngenyameko kwinqanaba ngalinye, ukusuka kwiimfuno zemeko kunye nokusebenza kwezinto eziphathekayo ukuya kumgangatho wemveliso kunye nodumo lomthengisi. Ukukhetha okufanelekileyo akuqinisekisi kuphela ukhuseleko kodwa kwandisa kakhulu ubomi benkonzo kunye nokusebenza kakuhle kweemveliso.
