Tus Kheej Kev Nyab Xeeb Grounding Equipment Overhead Line Security Earth Wire
Khoom taw qhia
Kev ruaj ntseg hauv ntiaj teb hlau yog tsim rau cov kab sib txuas, cov chaw tsim hluav taws xob thiab cov khoom siv hluav taws xob substation, luv Circuit Court grounding rau hluav taws xob tu.
Kev ua tiav ntawm kev ruaj ntseg hauv ntiaj teb hlau muaj cov khoom siv hluav taws xob ua haujlwm nrog cov khoom siv hluav taws xob, cov khoom siv hluav taws xob hloov tau yooj yim tooj liab nrog pob tshab sheath, grounding pin lossis grounding clip.
Lub conductive clamp yog muab faib ua: ob lub caij nplooj ntoos hlav conductive clamp thiab ncig kauv conductive clamp siv los clamp tus neeg xyuas pib, thiab tiaj tus kauv conductive clamp siv los clamp lub busbar.
1. Hlau clamper nrog aluminium alloy casting, siab zog, zoo conductivity.
2.The portable short-circuit grounding wire yog ntim rau hauv lub hnab canvas nrog exported ntoo thawv, uas yog ib qho yooj yim mus nqa thiab thauj.
teeb meem xav tau kev saib xyuas:
1. Ua ntej xyuas seb kab puas nyob thiab paub meej tias tsis muaj hwj chim.
2. Txuas lub davhlau ya nyob twg hauv av ua ntej thiab tom qab ntawd tus neeg xyuas pib lub davhlau ya nyob twg.Cov txheej txheem ntawm kev tshem tawm cov xaim hauv av yuav tsum thim rov qab;
3. Cov hnab looj tes insulating yuav tsum siv rau kev sib dhos thiab disassembling grounding wires.Tib neeg lub cev yuav tsum tsis txhob kov cov xaim hauv av lossis cov xov hlau uas raug kaw los tiv thaiv kev ua haujlwm inductive.
