Izicateleni nezinye zokuthula ezinethiwe ngamnyama zihleli amandla nokuba kahle kunye nesiphumo esisodwa sezikhundleni ezithile kakhulu kunye namaphrojekthi yezikhundla: Izicateleni nezinye zokuthula ezinethiwe ngamnyama zihleli ukungqinisekiswa kwemfuyo wesintathu kunye nokugcwaliswa okukhawuleza okanye ukususa ukuhambisana ngekomponyenti zakhoze lokuphucwayo. Izicateleni nezinye zokuthula ezinethiwe ngamnyama zihlala kwiqinisekiso lemfazwe, umsebenzi wokulubola ngesintu, kunye nokungabuyabuya ngokusebenzisa imoya.
Kwiminyaka yesibini, izicateleni nezinye zokuthula ezinethiwe ngamnyama zihlala kwiqinisekiso lokuncane kwezindlu, ubuhle obuchaze, isifundo sesityalo esisidingi, kunye nokuhlala kwenqanawe, okungakuvunyiswa ukwenza usapho lomkhonto kunye nokusetyenziswa ngokukhangelwa. Iziphrojekthi zokuthula ezinethiwe ngamnyama zihlala kwe-450/750V kwegumbi lokusebenza olufanelekileyo kunye nokusetshenziswa kwindawo yokuhlala, iindlela, kunye nokuhlala.
Umgca wokusebenza kwezinsuku ezininzi ngumthi wokuqala ukuqonda nge-90 ℃ okanye 75 ℃, futhi umthi wokulayisha ayikwazi ukufakwa ngaphambili kwe-0 ℃. Umphathelano wokubhuka ayikwazi ukuba yisiso sesithathu eside kunye nomdabuko wekhabhele.
Jiangsu Elesun Cable inekuvaniseni elincinci lokuhlala kwiTHHN nenxibelelo le-UL. Ngenxa yokuhlala yomlomo omkhulu, umbaluleko wenqanawe wahlukile eUSA ngowe-2009.
