Lub metering hlws ris lub thawv yog ib lub thawv tshwj xeeb hauv cov thawv sib txuas ntawm cov khoom siv hluav taws xob. Nws kuj tseem tsim nyog rau cov kab hluav taws xob theem nrab nrog cov ntsuas hluav taws xob txog li 660 volts thiab ntsuas tam sim no txog 20A. Nws yog siv rau kev hloov chaw nyab xeeb lossis ntawm -kev tshuaj xyuas qhov chaw ntawm cov ntsuas hluav taws xob, cov cuab yeej hluav taws xob, cov khoom siv tiv thaiv cov pa taws, thiab lwm yam khoom siv hluav taws xob hauv qab thauj khoom, ua kom muaj kev nyab xeeb ntawm tus kheej thiab txhim kho ntawm - qhov chaw ua haujlwm zoo.,
Lub thawv hlws ris feem ntau yog ua los ntawm Asmeskas cov khoom siv siab tshaj -polymer polycarbonate, uas muaj ntau yam zoo xws li kev cuam tshuam lub zog, kev laus tsis kam, dej tsis kam, nplaim hluav taws kub, thiab kub tsis kam. Nws muaj cov xim ci thiab zoo nkauj, thiab nws cov khoom ua tau zoo dua ntxiv. Nws pab daws qhov tsis txaus ntawm cov khoom siv bakelite ib txwm muaj, xws li brittleness thiab fragility, dej nqus thiab fogging, uas ua rau theem nrab ntawm cov CTs thiab yooj yim tawg hauv PTs.
