Xa uyila imveliso yombane, ukukhetha intambo efanelekileyo kubalulekile ekusebenzeni ngokubanzi kunye nokhuseleko lwesixhobo. Ngoko ke, ukhetho lweUL (Underwriters Laboratories) iintambokuthathwa njengento ebalulekileyo kubenzi abajonge ukuqinisekisa abathengi kunye nabathengi ukuba iimveliso zabo zithembekile kwaye zikhuselekile ukuzisebenzisa.
I-UL yintlangano yovavanyo oluzimeleyo kunye nesiqinisekiso esibeka imigangatho yokhuseleko kunye nokusebenza kwiindawo ezahlukeneyo ezibandakanya iimveliso zombane kunye ne-elektroniki, i-fiber optics, ucingo kunye nekhebula.UL (Underwriters Laboratories) iintamboisatifikethi siqinisekisa ukuba iintambo zidlula uvavanyo olungqongqo kwaye zithobela imigangatho yolawulo enxulumene nokhuseleko lwemveliso.
Zininzi izinto eziza kudlala xa ukhetha intambo ye-UL echanekileyo. Oku kubandakanya ukuphuma kwamandla kwentambo. Ukukhutshwa kwamandla ekhebula kuchazwa ngumlinganiselo wamandla ikhebula elihambisa kwindawo ethile. Ikhebula eliphezulu elisebenza kakuhle liya kuba namandla aphezulu ngaphezu kwentambo ephantsi.
Kubalulekile ukukhetha ikhebula ngeyona nto ingcono kakhulu njengoko iya kugqiba amandla amaninzi anokuthi adluliselwe. Ukuba i-cable output ayinelanga, iya kuchaphazela ukusebenza kwezixhobo, kubangele ukusetyenziswa kwamandla ngokufanelekileyo kunye nokuchithwa kwezixhobo. Umzekelo, iintambo ezikhupha imveliso ephantsi ezisetyenziselwa ukunika amandla izixhobo zokusebenza ezikumgangatho ophezulu zinokukhokelela ekunciphiseni ukusebenza kakuhle kwaye mhlawumbi nokusilela kwezixhobo.
Ukongeza kwimveliso yamandla, kukho ezinye izinto ekufuneka ziqwalaselwe xa ukhetha ezifanelekileyoUL (Underwriters Laboratories) iintambokwiprojekthi yakho:
1. Ukugqunywa kwentambo: Ukusebenza kwe-insulation yekhebula kuya kuqinisekisa ukhuseleko lwayo jikelele kunye nokusebenza kakuhle. Jonga iintambo ezinezinga eliphezulu lokugquma, njengePVC, iXLPE okanye iTPE. Eyaziwayo ngokuhlala kwayo, ukuxhathisa i-abrasion kunye nokuchasana nokushisa okukhulu, ezi zixhobo zifanelekile kwiindawo ezinzima.
2. Umlinganiselo wombane: Umbane olinganisiweyo wentambo umisela i-voltage enokumelana nayo ngaphambi kokuphuka okanye ukungaphumeleli. Qinisekisa ukuba intambo inikwe ireyithi yomgangatho ochanekileyo wombane wesixhobo esiza kusetyenziselwa umbane.
3. Ubungakanani bentambo: Ubungakanani bekhebula yingqwalasela ephambili. Ukukhetha intambo encinci kunokubangela ukulahleka kwamandla ngenxa yokumelana nentambo, enokuthi yenzeke ngexesha lokuhanjiswa, ngakumbi kumgama omde. Iintambo ezinkulu ziya kunciphisa ukulahleka kwamandla.
4. Ukuba bhetyebhetye:Ukuguquguquka kwentambo kubaluleke ngokulinganayo, ngakumbi kwizicelo apho intambo kufuneka ihanjiswe, igobe, kwaye iphathwe rhoqo. Ikhebula eliguquguqukayo liya kunciphisa ukunxiba kunye nokwandisa ubomi bayo.
5. Umlinganiselo wokusiNgqongileyo: Ngokuxhomekeke kwisicelo, ezinye iintambo zingadinga ukuba zingamanzi, umlilo okanye ukumelana neekhemikhali. Qinisekisa ukuba intambo oyikhethayo ifanelekile kwiimeko zokusingqongileyo apho intambo iya kubonakaliswa ngexesha lokusetyenziswa.
Isishwankathelo, ukukhetha okulungileyoUL (Underwriters Laboratories) iintambokuba iprojekthi yakho ibalulekile ekusebenzeni ngokupheleleyo kunye nokhuseleko. Qwalasela le miba ingasentla enje ngokuphuma kwamandla, ukugqunywa kwentambo yombane, amandla ombane alinganisiweyo, ubungakanani bentambo, ukuguquguquka kunye nokulinganisa okusingqongileyo ukwenza isigqibo esinolwazi.
Ukusebenzisa iintambo ezidweliswe ngu-UL kwiprojekthi yakho kuya kwenza imveliso yakho ikhuseleke ukuba ingasetyenziswa kwaye ithobele imigangatho yolawulo. Iya kuqinisekisa ukuba izixhobo zisebenza ngeyona ndlela ingcono, ukunciphisa ixesha lokuphumla, ukwandisa ukusebenza kakuhle, kunye nokwandisa ubomi besixhobo sakho.
