Txheej txheem cej luam ntawm Technical Standards rau Fais Fab Distribution Boxes

Raws li qhov tseem ceeb ntawm lub zog hluav taws xob, cov kev xav tau ntawm cov thawv xa khoom ncaj qha cuam tshuam rau hluav taws xob kev nyab xeeb thiab kev ntseeg tau ntawm lub cev. Raws li lub teb chaws tus qauv GB7251 thiab lwm yam specifications, cov txheej txheem kev faib cov thawv yog feem ntau muab faib ua plaub yam tseem ceeb: cov qauv dav dav, lub cev lub cev, cov khoom, thiab cov kab sib dhos.

 

Cov kev cai dav dav muaj xws li: tag nrho cov kev ntsuas kev tsim khoom yuav tsum ua tau raws li cov kev qhia tshwj xeeb thiab cov qauv tsim, thiab kev tsim khoom yuav tsum nruj me ntsis ua raws li cov qauv kev ua tiav. Cheebtsam thiab technical parameters yuav tsum tau raws li GB7251 tus qauv hauv lub tebchaws. Tom qab cov qauv ntau lawm, cov khoom loj tuaj yeem pib tsuas yog tom qab tau txais kev sib koom ua ke los ntawm chav tsev tsim kho, chav saib xyuas, thiab chav tsev tsim kho.

 

Lub cev lub cev yuav tsum tau ua: lub thawv lub cev cov khoom yuav tsum ua tau raws li lub teb chaws cov qauv, feem ntau yog siv txias -rolled steel phaj; pem teb- cov thawv sawv ntsug yuav tsum tau nruab nrog lub hau npog sab saum toj; Cov thawv xa khoom zoo ib yam yuav tsum tsis txhob muaj qhov khoob khoob; lub thawv lub cev yuav tsum muaj ob - qhov rooj qauv.
