Cov ntaub ntawv pov thawj tawg (tseem sau cov ntawv pov thawj tawg) yog cov khoom sib txuas ua ke siv rau hauv qhov chaw muaj kev phom sij.Lawv muaj cov khoom siv hluav taws xob sib txawv xws li: lub davhlau ya nyob twg thaiv, cov keyboards, transformers, relays thiab lwm yam arching & sparking devices.Cov thawv no tau tsim kho kom muaj qhov tawg hauv qhov hluav taws xob los ntawm cov pa roj, vapors, plua plav thiab fibers kom muaj kev nyab xeeb nyob ib puag ncig.Lawv yog cov resistant rau corrosion thiab tuav ib tug siab kam rau ua rau huab cua kub.Cov ntaub thaiv npog flameproof no yog cov tshuaj zoo tshaj plaws rau cov chaw muaj kev phom sij.Ua pov thawj tawg, lawv yuav muaj cov khoom tawg sab hauv los ntawm kev sib kis mus rau ib puag ncig sab nraud, yog li tiv thaiv kev raug mob thiab kev puas tsuaj ntawm cov khoom.
Qhov chaw muaj kev phom sij tawg-pov thawj thiab cov ntaub thaiv npog flameproof tau muab faib ua cov kev tiv thaiv sib txawv, nyob ntawm qhov chaw thiab qib kev tiv thaiv lawv muab.Cov kev ntsuam xyuas no yog ua raws li National Electrical Manufacturers Association (NEMA) cov qauv, thiab tseem muaj tus qauv thoob ntiaj teb EN 60529 rau Ingress Protection (IP) uas qhia txog qib kev tiv thaiv hluav taws xob xws li corrosion, plua plav, nag, txaws & hose-directed dej. thiab kev tsim dej khov.
Cov ntaub ntawv pov thawj tawg yog tsim los nrog cov xov txuas txuas ntxiv uas ua kom txias thiab muaj qhov tawg hauv qhov chaw kaw.Yog li ntawd, tej yam muaj peev xwm hluav taws xob arc uas tshwm sim yuav tsis kis mus rau sab nraud explosive cua.
● Nws muaj kev nyab xeeb thiab txhim khu kev qha hauv cov huab cua tawg.
● Cov ntaub ntawv pov thawj tawg pab txhua tus neeg ua haujlwm hauv qhov chaw muaj kev phom sij nyob nyab xeeb thaum muaj xwm txheej.Nws kuj txo qhov kev puas tsuaj.
● Cov khoom siv nyob rau hauv lub thawv yog ruaj khov.Nws muaj kev tiv thaiv siab.
● Nws ua raws li cov qauv kev nyab xeeb siab tshaj plaws.
● Nws muaj kev tiv thaiv siab.
