Kwihlabathi lokufakelwa kombane, amagama athi “i-NEMA cable ladder” kunye “Itreyi yekhebula ye-NEMA"iinkcukacha" zihlala zikhankanywa. Ezi ngcamango zibalulekile ekuqinisekiseni ulawulo lweentambo olukhuselekileyo nolusebenzayo kwiindawo ezahlukeneyo, ukusuka kwiindawo zoshishino ukuya kwizakhiwo zorhwebo. Eli nqaku liza kuhlola ukuba yintoni ileli yentambo ye-NEMA kwaye likhanyise iinkcukacha zetreyi yentambo ye-NEMA.
Yintoni iIleli yekhebula ye-NEMA?
Ileli yentambo ye-NEMA luhlobo lwenkqubo yolawulo lwentambo esetyenziselwa ukuxhasa nokulungelelanisa iintambo. Igama elithi “NEMA” limele iNational Electrical Manufacturers Association (NEMA), ebeka imigangatho yezixhobo zombane kunye nezinto ezisetyenziswayo eMelika. Iileli zentambo ze-NEMA zihlala zenziwe ngezinto ezifana ne-aluminium okanye intsimbi kwaye zenzelwe ukubonelela ngesakhelo esomeleleyo sokuhambisa nokukhusela iintambo.
Uyilo lweleli yentambo ye-NEMA lunemigangatho okanye iibhari ezinqamlezayo ezivumela iintambo ukuba zilale zithe tyaba, nto leyo enciphisa uxinzelelo kunye nomonakalo onokubakho. Olu yilo lusebenza ngakumbi xa iintambo kufuneka ziqhutywe kumgama omde okanye kwiindawo ezinoxinano olukhulu lweentambo. Ulwakhiwo oluvulekileyo lweleli yentambo lukwakhuthaza ukujikeleza komoya, lunceda ekususeni ubushushu obuveliswa ziintambo, ngaloo ndlela luphucula ukhuseleko kunye nokusebenza.
Ukubaluleka kweMigangatho ye-NEMA
Imigangatho ye-NEMA idlala indima ebalulekileyo ekuqinisekiseni ukuba izixhobo zombane, kuquka iileri zekhebula kunye neetreyi, ziyahlangabezana nemigangatho ethile yokhuseleko kunye nokusebenza. Le migangatho iphuhliswa ngokuvumelana phakathi kwabavelisi, abasebenzisi, kunye nabanye abachaphazelekayo kushishino lombane. Ngokuthobela imigangatho ye-NEMA, abavelisi banokuqinisekisa ukuba iimveliso zabo zithembekile, zikhuselekile, kwaye ziyahambelana nezinye izinto zombane.
Yintoni iIkhowudi ye-NEMA yetreyi yekhebula?
Iinkcukacha ze-NEMA zeetreyi zekhebula zichazwe kumgangatho we-NEMA VE 2, obonelela ngesikhokelo soyilo, ulwakhiwo, kunye nokufakwa kweetreyi zekhebula. Lo mgangatho ubalulekile ekuqinisekiseni ukuba iitreyi zekhebula zinokuxhasa ngokukhuselekileyo ubunzima beentambo ngelixa zibonelela ngokhuseleko olufanelekileyo kwizinto ezingqongileyo ezifana nokufuma, uthuli, kunye nomonakalo womzimba.
Umgangatho we-NEMA VE 2 uhlela iitreyi zekhebula kwiintlobo ezahlukeneyo, kuquka iitreyi zeleli, iitreyi ezisezantsi eziqinileyo, kunye neetreyi zetrough. Uhlobo ngalunye lunezicelo ezithile kunye neenzuzo, kuxhomekeke kwindawo yokufakela kunye nohlobo lwekhebula elisetyenzisiweyo. Umzekelo, iitreyi zeleli zilungele ukusetyenziswa okunzima okufuneka kuxhaswe inani elikhulu leentambo, ngelixa iitreyi ezisezantsi eziqinileyo zilungele ngakumbi iindawo apho uthuli kunye nenkunkuma zingumcimbi.
Xa ukhetha kwaye ufaka iileyidi zekhebula ze-NEMA kunye neetreyi, kufuneka kuqwalaselwe izinto ezininzi:
1. **Umthamo wobunzima**: Qinisekisa ukuba ileli yentambo okanye itreyi yentambo inokuxhasa ubunzima beentambo ezifakelwayo. Oku kuquka ukuqwalasela ubunzima beentambo ngokwazo kunye nezinye izinto ezifana neemeko zokusingqongileyo.
2. **Ukukhetha Izinto**: Khetha izinto ezifanelekileyo kwindawo eziza kufakelwa kuyo. Umzekelo, kwindawo enokugqwala, i-aluminium isenokuba yinto ekhethwayo; ngelixa intsimbi isenokuba yeyona ifanelekileyo kwiindawo ezinzima.
3. **Iyahambelana ne-NEMA**: Soloko ubhekisa kwimigangatho ye-NEMA VE 2 ukuqinisekisa ukuba inkqubo yetreyi yekhebula iyahlangabezana nazo zonke iimfuno zokhuseleko kunye nokusebenza ezifunekayo.
4. **Iindlela zokufakela**: Landela iindlela zokufakela ezilungileyo ukuqinisekisa ukuba iileri zekhebula okanye iitreyi zifakelwe ngokukhuselekileyo kwaye iintambo zibekwe ngendlela efanelekileyo kwaye zikhuselekile.
Iileli zekhebula ze-NEMAkunye neenkcukacha zetreyi yekhebula ye-NEMA zibalulekile kulawulo olusebenzayo lwekhebula kufakelo lombane. Ngokuqonda iinkcukacha kunye nemigangatho ebekwe yi-NEMA, iingcali zinokuqinisekisa ukuba ukufakelwa kwazo kukhuselekile, kusebenza kakuhle, kwaye kuyahambelana nemigaqo yoshishino. Nokuba kukwiindawo zoshishino, zorhwebo, okanye zokuhlala, ukusetyenziswa ngokufanelekileyo kweeleli kunye neetreyi zekhebula ze-NEMA kunokunyusa kakhulu ukuthembeka kunye nobomi beenkqubo zombane.
