YB-12/0.4 box-type substation (high and low voltage pre-installed substation) ndi high-voltage switchgear, thiransifoma yogawa ndi kachipangizo kakang'ono kagawidwe kamagetsi, malinga ndi ndondomeko ya mawaya yomwe imakonzedwa mu imodzi mwa fakitale yokonzedweratu m'nyumba. panja yaying'ono kugawa zida, ndiye thiransifoma sitepe-pansi, otsika-voteji kugawa ndi ntchito zina organically pamodzi. Anaika mu chinyontho, umboni dzimbiri, fumbi-umboni, makoswe-umboni, fireproof, anti-kuba, kutentha kutchinjiriza, otsekedwa mokwanira, zosunthika zitsulo kapangidwe bokosi, makamaka oyenera kumanga maukonde m'tauni ndi kusintha, ndi substation latsopano pambuyo kukwera kwa malo osungirako anthu. Box-type substation ndi yoyenera migodi, mabizinesi amafakitale, minda yamafuta ndi gasi ndi malo opangira magetsi amphepo, imalowa m'malo mwa chipinda choyambirira chogawa anthu, malo ogawa magetsi, ndikukhala seti yatsopano yamagetsi ndi zida zogawa.
YB mndandanda preassembled substation ali ndi makhalidwe amphamvu athunthu seti, yaing'ono, kapangidwe yaying'ono, otetezeka ndi odalirika ntchito, kukonza zosavuta, ndi kuyenda, etc. Poyerekeza ndi substation ochiritsira boma, bokosi substations ndi mphamvu yomweyo zambiri kuphimba dera la 1/10 ~ 1/5 yokha ya malo ochiritsira, omwe amachepetsa kwambiri mapangidwe a ntchito ndi zomangamanga, komanso amachepetsa mtengo womanga.
