Kev sib koom ua ke siab -voltage switchgear muaj siab -voltage fais fab faib khoom muab los ua tiav los ntawm cov chaw tsim khoom thiab tom qab sib dhos rau ntawm -site. Cov cuab yeej no faib cov hluav taws xob tseem ceeb rau hauv ntau lub voj voog; Txhua chav sib koom ua ke ib qho hluav taws xob hluav taws xob, disconnector, ntsuas hluav taws xob, thiab kev tiv thaiv thiab tswj cov khoom siv hauv ib lub txee. Ntau yam xws li switchgear txee tuaj yeem ua ke los tsim lub tshuab hluav taws xob rau cov chaw tsim hluav taws xob thiab cov chaw ua haujlwm.
Raws li cov yam ntxwv ntawm cov qauv, kev sib xyaw ua ke siab -voltage switchgear raug faib ua hom xws li hlau- kaw, hlau- kaw armored, hlau- kaw lub thawv- hom, thiab SF6 roj- insulated switchgear (GIS). Nyob ntawm txoj kev sib txuas ntawm lub tshuab hluav taws xob, nws yog categorized raws li ib qho ruaj khov - hom lossis tshem tau - hom (trolley- hom); Raws li kev teeb tsa ib puag ncig, nws raug cais raws li sab hauv lossis sab nraum zoov. Cov cuab yeej tau nruab nrog "Tsib-Kev Tiv Thaiv" cuam tshuam kev ua haujlwm, siv cov khoom siv hluav taws xob lossis hluav taws xob cuam tshuam los tiv thaiv kev ua haujlwm tsis raug thiab ua kom muaj kev nyab xeeb ntawm kev ua haujlwm.
