YB-12/0.4 box-type substation (siab thiab tsis tshua muaj hluav taws xob ua ntej-ntsia substation) yog lub tshuab hluav taws xob high-voltage switchgear, tis transformer thiab low-voltage tis ntaus ntawv, raws li ib qho kev xaim hluav taws xob tau npaj rau hauv ib qho ntawm lub Hoobkas prefabricated sab hauv tsev thiab Sab nraum zoov compact faib khoom, uas yog, transformer step-down, low-voltage tis thiab lwm yam dej num organically ua ke. Muab tso rau hauv cov ntaub ntawv pov thawj noo noo, xeb-pov thawj, plua plav pov thawj, nas-pov thawj, hluav taws kub, tiv thaiv tub sab, rwb thaiv tsev kub, tag nrho ntim, txav tau steel qauv lub thawv, tshwj xeeb tshaj yog tsim rau kev tsim kho hauv nroog thiab kev hloov pauv, yog lub chaw tsim khoom tshiab tom qab. qhov nce ntawm pej xeem substations. Box-type substation yog tsim rau mines, industrial enterprises, roj thiab roj teb thiab cua fais fab chaw nres tsheb, nws hloov lub qub pej xeem faib chav tsev, tis fais fab chaw nres tsheb, thiab dhau los ua ib tug tshiab ua tiav txheej ntawm transformer thiab faib khoom.
YB series preassembled substation muaj cov yam ntxwv ntawm lub zog ua tiav, me me, compact qauv, kev nyab xeeb thiab txhim khu kev qha, yooj yim txij nkawm, thiab kev txav mus los, thiab lwm yam. tsuas yog 1/10 ~ 1/5 ntawm cov chaw ua haujlwm ib txwm siv, uas txo qis cov qauv tsim thiab kev tsim kho tus nqi, thiab txo cov nqi tsim kho.
