Cov hluav taws xob xa hluav taws xob, tseem hu ua hluav taws xob xa hluav taws xob, yog hom hluav taws xob xa hluav taws xob thiab ib qho tseem ceeb ntawm cov kab xa hluav taws xob. Lawv txhawb nqa thiab tshem tawm cov kab hluav taws xob, ua kom muaj kev nyab xeeb thiab txhim khu kev xa hluav taws xob. Cov ncej sib kis muaj xws li ob pawg tseem ceeb: cov pob zeb muaj zog thiab cov yees hluav taws xob. Hauv kuv lub teb chaws txoj kev xa hluav taws xob uas twb muaj lawm, cov qauv hluav taws xob ntauwd feem ntau yog siv rau cov kab uas muaj qhov hluav taws xob ntawm 110kV lossis siab dua, thaum cov pob zeb ua vaj huam sib luag feem ntau yog siv rau cov kab uas muaj qhov voltage tsis tshaj 66kV. Cov xwm txheej muaj feem xyuam rau cov yees hluav taws xob muaj feem cuam tshuam nrog cov kab hluav taws xob theem, cov xwm txheej hauv av, thiab cov kev xav tau ntawm kev thauj khoom. Lawv yog siv nyob rau hauv tiaj tus, toj, roob, thiab ntev - ncua kev hla kev (xws li hla cov dej loj), thiab hom qauv zoo yuav tsum tau xaiv los ntawm kev sib piv kev lag luam thiab kev sib piv.
Tam sim no, lub ntiaj teb siab tshaj plaws hluav taws xob xa hluav taws xob ntauwd yog lub dav hlau sib kis ntawm Fengcheng -Meili 500kV Yangtze River Crossing Project. Qhov phiaj xwm no muaj ob lub 385-meter ultra- siab kis tau tus yees nrog qhov ntev ntawm 2550 meters hla tus dej, ua rau nws qhov loj tshaj plaws thiab cov txuj ci tseem ceeb tshaj plaws kev sib tw hla kev sib txuas hluav taws xob sib txuas hluav taws xob thiab kev hloov pauv hauv kuv lub teb chaws keeb kwm kev tsim hluav taws xob.
