Sab hauv tsev high voltage vcb yog ib qho hluav taws xob sab hauv tsev nrog peb-theem AC 50Hz rated voltage ntawm 12kV thiab 24kV fais fab tuag. Nws yog siv los ua kev tiv thaiv thiab tswj cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hauv kev lag luam thiab kev lag luam mining. Nws yog qhov tsim nyog rau qhov chaw uas yuav tsum tau ua haujlwm tsis tu ncua raws li kev ntsuas ua haujlwm tam sim no, lossis tawg luv-circuit tam sim no ntau zaus.
Siv tej yam kev mob
1. huab cua kub nyob ib puag ncig: sab sauv txwv ntxiv rau 40 degrees, qis dua -40 degrees;
2. Qhov siab: Tsawg dua lossis sib npaug li 2000m (yog tias qhov siab nce siab, qhov ntsuas qhov ntsuas hluav taws xob yuav nce raws li);
3. Cua siab: tsis ntau tshaj 700Pa (sib npaug rau cua ceev ntawm 34m/s);
4. Kev siv av qeeg: tsis ntau tshaj 8 degrees;
5. Qib kis kab mob: Ⅳ qib;
6. Qhov kub siab tshaj plaws txhua hnub sib txawv: tsis pub tshaj 25 degrees;
7. Tus txheeb ze av noo: qhov nruab nrab txhua hnub tsis ntau tshaj 95 feem pua, qhov nruab nrab txhua hli tsis tshaj 90 feem pua;
8. Qhov chaw uas tsis muaj qhov kub hnyiab, tawg ua rau muaj kev phom sij, tshuaj lom neeg corrosion thiab kev co hnyav.
