YB-12 / 0.4 pusa-ituaiga substation (maualuga ma maualalo voltage muaʻi faʻapipiʻiina substation) o se switchgear maualuga-voltage, tufatufaina transformer ma maualalo-voltage tufatufaina masini, e tusa ai ma se polokalame uaea faatulagaina i se tasi o falegaosimea prefabricated totonu ma meafaigaluega tufatufaina fa'apitoa i fafo, o lona uiga, transformer step-down, tufatufaina maualalo-voltage ma isi galuega tauave organically tuufaatasia faatasi. Faʻapipiʻiina i totonu o se susu-faʻamaonia, ele-faʻamaonia, pefu-faʻamaonia, iole-faʻamaonia, afi, anti-gaoi, faʻavela vevela, faʻapipiʻiina atoa, pusa faʻapipiʻi uʻamea, aemaise lava mo le fausiaina o fesoʻotaʻiga i le taulaga ma le suiga, o se substation fou pe a uma. o le tula'i mai o fale afi a le malo. Pusa-ituaiga substation e talafeagai mo maina, pisinisi alamanuia, suauu ma kesi fanua ma nofoaga malosiaga matagi, e sui ai le uluai potu tufatufaina lautele, nofoaga eletise tufatufaina, ma avea ma se seti atoatoa fou o transformer ma tufatufaina meafaigaluega.
YB series preassembled substation o loʻo i ai uiga o le malosi atoatoa seti, laʻititi laʻititi, fausaga faʻapipiʻi, saogalemu ma faʻatuatuaina faʻagaioiga, faigofie tausiga, ma feʻaveaʻi, ma isi. naʻo le 1/10 ~ 1/5 o substations masani, lea e faʻaitiitia ai le galuega faʻatulagaina ma le aofaʻi o le fausiaina, ma faʻaitiitia ai le tau o le fausiaina.
