Galvanized Steel Electrical Metallic Tubing (EMT) yog cov khoom siv hluav taws xob zoo heev los siv tam sim no muaj nyob hauv khw.

EMT yog tsim los ntawm cov hlau muaj zog, thiab tsim los ntawm cov txheej txheem vuam hluav taws xob.

Sab hauv thiab sab nrauv ntawm EMT yog dawb los ntawm qhov tsis xws luag nrog ib tug du welded seam, thiab ua tib zoo coated nrog zinc siv kub dip galvanizing txheej txheem, thiaj li hais tias hlau-rau-hlau sib cuag thiab galvanic tiv thaiv corrosion yog muab.

Qhov saum npoo ntawm EMT nrog lub ntsej muag ntshiab tom qab galvanizing los muab kev tiv thaiv ntxiv tiv thaiv corrosion. Sab hauv nto muab ib tug du nruam raceway rau yooj yim hlau rub. Peb EMT conduit muaj ductility zoo heev, muab kev khoov zoo, txiav hauv thaj teb.

EMT yog tsim nyob rau hauv ib txwm ua lag luam loj los ntawm ? rau 4". EMT yog tsim nyob rau hauv tus qauv ntev ntawm 10' (3.05 m). Qhov kom muaj nuj nqis hauv pob khoom thiab tus tswv pob khoom yog raws li cov lus hauv qab no. Cov pob khoom tiav ntawm EMT raug txheeb xyuas nrog cov xim coded daim kab xev rau kev txheeb xyuas qhov loj me.

Nta thiab Cov txiaj ntsig
