YB-12/0.4 box-type substation (yakakwirira uye yakaderera voltage pre-yakagadzikwa substation) ndeye yakakwira-voltage switchgear, dhizaini yekuparadzira uye yakaderera-voltage yekuparadzira mudziyo, zvinoenderana neimwe wiring scheme yakarongwa mune imwe yefekitori yakagadzirirwa mukati uye. zvekunze compact kugovera midziyo, kureva, transformer nhanho-pasi, yakaderera-voltage kugovera uye mamwe mabasa organically akasanganiswa pamwechete. Yakaiswa muunyoro-uchapupu, ngura-proof, guruva-proof, gonzo-proof, fireproof, anti-kuba, kupisa kupisa, yakavharwa zvizere, inotakurika simbi yekugadzira bhokisi, kunyanya yakakodzera kuguta network kuvaka uye shanduko, inzvimbo nyowani mushure kusimuka kwezviteshi zvevagari vemo. Bhokisi-mhando substation inokodzera migodhi, mabhizinesi emaindasitiri, minda yemafuta negasi uye zviteshi zvemagetsi emhepo, inotsiva imba yekutanga yekugovera vanhu, chiteshi chemagetsi chekugovera, uye inova seti nyowani yakazara yeshanduko nemidziyo yekugovera.
YB series preassembled substation ine hunhu hwakasimba hwakakwana seti, diki diki, compact chimiro, yakachengeteka uye yakavimbika kushanda, kugadzirisa kuri nyore, uye kufamba, etc. Zvichienzaniswa neyakajairwa civil substations, bhokisi-mhando substations ine simba rakafanana rinowanzovhara nzvimbo ye chete 1/10 ~ 1/5 yezviteshi zvakajairwa, izvo zvinoderedza zvakanyanya basa rekugadzira uye huwandu hwekuvaka, uye inoderedza mutengo wekuvaka.
