Lub 500 kV Gejun Kab tau muab tso rau hauv kev ua haujlwm hauv xyoo 1983. Nws tau 40 xyoo. Cov cuab yeej yog qub thiab cov kev ua haujlwm tsis zoo, yog li nws yog qhov yuav tsum tau kho dua tshiab. Kev tsim kho ntawm txoj haujlwm kho dua tshiab tau ua los ntawm Lub Xeev Grid Hubei Fais Fab Kis thiab Hloov Kho Engineering Co., Ltd. pib ntawm Gezhouba Hydropower Station thiab xaus rau ntawm Jinghe Village, Jiyukou Town, Qianjiang City, Hubei Province, hla dhau 7 lub nroog thiab lub nroog suav nrog Yichang City , Jingzhou City, Jingmen City, Qianjiang City, Hubei Province. Qhov ntev ntawm txoj kev yog 143.8 km. Tag nrho ntawm 167 towers tau tsim, 162 yees raug rhuav tshem, thiab 214 yees tau siv. Lub qub 214-puab pej thuam thiab cov kab qhia hauv av tau rhuav tshem tag nrho 141.064 mais. Txoj kab kev tsim kho tau hla tus Dej Yangtze, kev nthuav dav, kev tsheb ciav hlau, txoj kev loj hauv tebchaws thiab cov kab hluav taws xob sib txawv ntawm 212 zaug, thiab nws siv sijhawm 159 hnub los ua tiav cov haujlwm tsim kho.
Txoj haujlwm kho dua tshiab yog ib qho ntawm cov kauj ruam tseem ceeb rau Hubei Power Grid los tsim "Gezhouba-Three Gorges" dual lub zog xa hluav taws xob, paub txog hluav taws xob sib cais ntawm Peb Gorges thiab Gezhouba lub zog xa hluav taws xob ntawm qhov kawg, tsim lub zog hluav taws xob dual. qauv ntawm Peb Gorges thiab Gezhouba fais fab kis tau tus mob nyob rau sab hnub poob Hubei, thiab ntxiv dag zog rau Gezhouba fais fab kis kab mob. Tom qab kev tsim hluav taws xob thiab kev xa tawm, nws yuav qhib qhov kev sib kis tseem ceeb rau kev xa khoom ntawm hydropower thiab lub zog huv ntawm Gezhouba.
