NG7-40.5 seriyasi SF6 gazli izolyatsiya qilinadigan o'g'it qurilmasi, Rockwill tomonidan IEC 62271-200 standartiga muvofiqlikda ishlab chiqarilgan yangi avlodning miniaturlangan mahsuloti.U turli kombinatsiyalarga ega va fleksibil holda kengaytirilishi mumkin, bu esa elektr taqsimot talablari asosida, shuningdek, turli ikkinchi bosqichli taqsimot loyihalarining kompakt o'g'it qurilmalari uchun keraklarini qondiradi. U umumiy elektr tarmoqlar, temir yo'llar, yangi energiya evlari, quvib yuzaga chiqarish maydonlari, shamol maydonlari, ma'lumot markazlari va boshqa yangi energiya sohalarida keng qo'llaniladi.
