Inzuzo yemveliso

Enye yezona nzuzo ziphambili zeetyhubhu ze-arc eziphantsi komhlaba ezikwizinga eliphezulu kukuqina kwazo okugqwesileyo kunye nokuqina kwazo. Inkqubo yokwenza ubanda iphucula ukuqina kwesakhiwo sezinto, okwenza zifaneleke kwiintlobo ngeentlobo zezicelo ezifuna umgudu, kuquka iiprojekthi zokwakha kunye neziseko zophuhliso. Ukongeza, iteknoloji yokudibanisa i-spiral ivumela ukuba kuveliswe iipayipi ezinde, nto leyo enciphisa isidingo samalungu kunye nokunciphisa iindawo ezibuthathaka ezinokubakho.

Enye inzuzo ebalulekileyo kukuba le mibhobho ixabisa kancinci. Inkqubo yokuvelisa isebenza kakuhle, nto leyo enokunciphisa iindleko zokuvelisa. Olu buchule, kunye nomgangatho ophezulu wemveliso yokugqibela, lwenza iityhubhu ze-arc eziphantsi komhlaba zibe lukhetho olunomtsalane kumashishini amaninzi.
