Zogulitsa zathu zatsopano, NVS1-12 mndandanda wamagetsi amkati amkati amagetsi apamwamba kwambiri amagwiritsidwa ntchito posintha ma switchgear mumagetsi a 12kV, ngati gawo lowongolera ndi chitetezo cha zida zamagetsi m'mabizinesi akumafakitale ndi migodi, zopangira magetsi ndi malo ocheperako. Chifukwa cha ubwino wapadera wa vacuum circuit breaker, ndizoyenera kwambiri kugwira ntchito pafupipafupi zomwe zimafuna kuti zigwiritsidwe ntchito panopa, kapena malo omwe magetsi afupikitsa amasweka kangapo. Wophwanyira dera amatengera mapangidwe ophatikizika a makina ogwiritsira ntchito ndi thupi lophwanyira dera. Awiriwa ndi mawonekedwe a kutsogolo ndi kumbuyo, omwe ali ndi ntchito yodalirika yolumikizirana. Wowononga dera angagwiritsidwe ntchito ngati gawo lokhazikika. Itha kukhalanso ndi galimoto ya chassis kukhala gawo langolo yamanja.
