Lub metering junction box yog ib qho tshwj xeeb hlws ris lub thawv ntawm cov qauv junction thawv rau hluav taws xob metering li. Nws yog qhov 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 tso cai rau kev nyab xeeb hloov lossis tshuaj xyuas cov ntsuas hluav taws xob thiab lwm yam khoom siv hluav taws xob hauv qab thauj khoom, ua kom cov neeg siv kev nyab xeeb thiab txhim kho kev ua haujlwm. Nws lub vaj tse yog ua los ntawm tuag- nrum txhuas alloy, nrog O- nplhaib roj hmab foob ntxiv rau qhov tawg- pov thawj nto, ua tiav qhov kev ntsuam xyuas IP65 thiab kev ua haujlwm tsis zoo. Lub cev tseem ceeb yog ua los ntawm siab-polymer polycarbonate cov ntaub ntawv, muaj kev cuam tshuam siab, nplaim taws retardancy, thiab siab -kub tsis kam, nrog rau kev khiav hauj lwm kub ntawm -40℃rau +60℃.
Lub thawv sib txuas no yog tsim rau Zone 1 thiab Zone 2 qhov chaw muaj kev phom sij thiab Chav Kawm IIA, IIB, thiab IIC explosive gas ib puag ncig. Plua plav tawg- hom pov thawj tuaj yeem kho raws li qhov yuav tsum tau ua. Cov qauv khoom tseem ceeb suav nrog XKM/JHD series ib zaug -theem / peb-theem metering hlws ris lub thawv, FJ6 / DFY1 tiv thaiv- tub sab peb-theem plaub- hlau hlws ris lub thawv, thiab FJ6 / JHT siab {{13{1} 4CC} cov khoom tshwj xeeb tam sim no, thiab lwm yam. ntawv pov thawj, CQC ntawv pov thawj thiab CE daim ntawv pov thawj, thiab ua raws li International Electrotechnical Commission cov qauv thiab lub teb chaws / kev lag luam qauv.
