Prefabricated substation, tseem hu ua prefabricated transformer substation, yog ib lub Hoobkas -prefabricated, compact sab hauv tsev / sab nraum zoov fais fab faib chav tsev uas integrates siab-voltage switchgear, tis transformers, thiab low-voltage fais fab faib khoom raws li ib tug tshwj xeeb wiring scheme. Nws organically sib xyaw ua ke transformer voltage txo thiab qis-voltage fais fab faib ua haujlwm, txhua lub tsev nyob hauv cov dej noo- pov thawj, xeb- pov thawj, plua plav- pov thawj, nas- pov thawj, hluav taws kub - pov thawj, tub sab tub nyiag{10}} pov thawj, cua sov{11}} pov thawj, lub thawv ntim khoom, thiab cov qauv hlau muaj peev xwm kaw tau. Nws yog qhov tshwj xeeb tshaj yog tsim nyog rau kev tsim kho vaj tse hauv nroog thiab kev kho dua tshiab, thiab sawv cev rau hom tshiab substation uas tau tshwm sim tom qab tsoos civil engineering substations.
Prefabricated substations yog tsim rau mines, factories, roj thiab roj av, thiab cua fais fab chaw nres tsheb. Lawv hloov cov tsoos civil engineering substations thiab faib chav, dhau los ua ib hom tshiab ntawm kev xa hluav taws xob ua tiav.
