ZBW-12/0.4 pre-ntsia substation yog hom American-style prefabricated box-hom substation. Raws li ib qho kev sib xyaw ua ke ntawm cov khoom siv prefabricated, nws sib txuas cov kab hluav taws xob ntawm cov khoom siv hluav taws xob faib hluav taws xob, cov khoom siv hluav taws xob siab thiab kev tiv thaiv, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob. Nws yog dav siv nyob rau hauv nroog thiab nyob deb nroog fais fab kev faib network.

Cov khoom yog nruab nrog siab -voltage load switches thiab siab -voltage fuses nyob rau hauv lub transformer roj tank, thiab muaj ob yam qauv: integrated transformer tank thiab cais transformer tank. Lub tank txais cov qauv kaw tag nrho, thiab tau nruab nrog cov ntsuas roj kub, ntsuas roj qib ntsuas, ntsuas ntsuas siab, lub siab tso tawm li qub, cov dej ntws tawm, thiab lwm yam khoom siv los saib xyuas kev ua haujlwm ntawm lub tshuab hloov pauv.

Raws li hom fais fab mov, cov khoom tau muab faib ua lub nplhaib network hom thiab hom davhlau ya nyob twg. Txhawm rau ua kom cov khoom no tsim nyog rau cov kev xav tau tiag tiag ntawm Tuam Tshoj txoj kab hluav taws xob, peb lub tuam txhab kuj tau pib ntsaws- hom fuses, uas tsis cuam tshuam rau kev ua haujlwm ntawm cov roj transformer.

Raws li qhov nyuaj ntawm qis-voltage outgo circuits, ZBW-12/0.4 cov khoom tau muab faib ua peb hom txee: hom qauv, hom kev txhim kho, thiab hom dav. Qhov no tso cai rau cov neeg siv thiab cov qauv tsim ua kom hloov tau yooj yim dua thiab raug nqi xaiv.
