Intambo ye-UL1277 yeyona nto iphambili kwishishini lamandla. Ukusetyenziswa kwentambo yenayiloni ye-TC-ER kubanzi kakhulu. Okokuqala, inokungcwatywa ngokuthe ngqo phantsi komhlaba, ngaphakathi, kwimibhobho, nangaphandle ukuze kuhanjiswe umbane kwiimeko ezigqithisileyo. Akukho monakalo kumhlaba ojikelezileyo kunye nokusingqongileyo, ukuthobela ngokupheleleyo iimfuno zokukhusela i-ROHS. Okwesibini, inokuthintela iimpuku kunye neembovane ukuba zilume intambo, ziqinisekise ukusebenza okuzinzile kwentambo. Akukona nje ukuphucula ubomi benkonzo yeentambo, kodwa kwandisa ukusebenza kakuhle kunye nokuzinza kokuhanjiswa kwamandla.
Intambo ye-UL1277 eyenziwe nguJiangsu Elesun Cable, kunye ne-TC-ER ye-nylon sheath yayo ekhethekileyo, izise amathuba amatsha kwishishini lamandla. Olu hlobo lwentambo alunayo nje ukuguquguquka okugqwesileyo kunye nokunganyangeki, kodwa luneempawu zokuzithambisa kunye nokwenziwa okugqwesileyo, okwenza ukuba ilungele iimeko ezahlukeneyo ezigqithisileyo.
Intambo ye-UL1277 luhlobo lwentambo ehambelana nemigangatho ye-UL1277, kuquka i-TC, i-TC-ER, kunye neentambo ze-nayiloni ze-FT4 ezingenamlilo. Ezi ntambo zisetyenziswa kwihlabathi jikelele.
