Ulayini wokukhiqiza wenqwaba yokushaja we-DC uwulayini wokukhiqiza osebenzayo owenzelwe ukukhiqiza izinqwaba zokushaja ze-DC. Ulayini wokukhiqiza wamukela ubuchwepheshe obuthuthukisiwe bokuzenzakalela kanye nemishini, okuhlanganisa imodyuli yesiteshi sikagesi esinemigqa emibili esindayo, imojula yokuphakamisa phezulu naphansi, njll., ukuqinisekisa ukunyakaza okuzenzakalelayo kanye nokuma okunembile kwezinqwaba zokushaja emgqeni womhlangano. Ngaleso sikhathi, imigqa yomoya ecindezelwe iyasethwa ngaphakathi kwawo wonke ulayini, futhi ukuxhumana kugcinwe ezindaweni ezihambisanayo ze-elementi ngayinye ukuze kuhlangatshezwane nesidingo sokukhiqiza. Lo mugqa wokukhiqiza unamandla okukhiqiza aqinile futhi ungaqedela ukukhiqizwa kwenqwaba yezinqwaba zokushaja ngesikhathi esifushane futhi uqinisekise ikhwalithi yomkhiqizo ozinzile nothembekile. Ukubonakala komugqa wokukhiqiza ozenzakalelayo we-DC wokushaja kuthuthukisa kakhulu ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo wenqwaba yokushaja, okunikeza ukwesekwa okuqinile kokuthandwa nokuthuthukiswa kwezimoto zikagesi.
