Raws li cov qauv kev lag luam, siab -voltage switchgear teeb pom kev zoo yuav tsum ua raws li cov qauv kev nyab xeeb hluav taws xob thiab kev tiv thaiv qib. Piv txwv li, qib kev tiv thaiv feem ntau yuav tsum ncav cuag IP30 lossis siab dua kom ntseeg tau tias cov khoom siv muaj qee theem ntawm plua plav thiab dej tsis kam. Nyob rau tib lub sijhawm, cov khoom siv kuj tseem yuav tsum dhau cov ntawv pov thawj kev nyab xeeb hluav taws xob, xws li 3C ntawv pov thawj, kom ntseeg tau tias lawv qhov zoo thiab kev nyab xeeb raws li cov qauv hauv tebchaws.
