Thaum Lub Peb Hlis 18, nyob rau hauv kev sib koom ua ke ntawm Lub Xeev Grid Equipment Department, China Electric Power Research Institute Co., Ltd. tau ua tus thawj coj hauv kev teeb tsa 27 lub tuam txhab hluav taws xob hauv lub xeev kom ua tiav qhov kev sim ua haujlwm ntawm random tshuaj xyuas cov khoom sib xyaw ua ke hauv kev ua haujlwm ntawm overhead kis kab.
Tag nrho ntawm 620 batch ntawm kev ua haujlwm cov khoom kuaj tau ua tiav hauv qhov kev sim ua piv txwv no. Qhov no yog thawj zaug uas State Grid Corporation ntawm Tuam Tshoj tau ua qhov kev ntsuam xyuas kev ua tau zoo ntawm cov khoom siv insulators hauv kev ua haujlwm raws li kev tswj hwm kev cai thiab kev coj ua. Composite insulators yog cov khoom tseem ceeb rau kev tiv thaiv cov pa phem flashover hauv lub tshuab hluav taws xob, tab sis muaj ntau cov qauv kev xeem thiab ob peb yam kev ua haujlwm rau cov khoom lag luam.
Tuam Tshoj Lub Tuam Txhab Hluav Taws Xob Tshawb Fawb tau siv sijhawm 2 xyoos, txheeb xyuas qhov ua tau zoo ntawm ntau dua 2, 000 pawg ntawm cov khoom lag luam, coj tus thawj coj hauv kev tsim cov txheej txheem kev tswj hwm rau random tshuaj xyuas ntawm cov khoom siv hluav taws xob hauv kev ua haujlwm rau cov khoom siv hluav taws xob, thiab xaiv ib qho me me ntawm cov khoom kuaj uas muaj qhov ntsuas tau siab. Ntxiv nrog rau cov qauv ntsuas tus yam ntxwv, qhov sib txawv ntawm cov qauv qauv kuj tau npaj rau qhov chaw ua haujlwm sib txawv.
