Kev siv cov xaim hluav taws xob muaj keeb kwm muaj ntau dua 100 xyoo

Kev siv cov xaim hluav taws xob muaj keeb kwm muaj ntau dua 100 xyoo. Xyoo 1879, Tus kws tsim qauv Asmeskas TA Edison qhwv lub jute rau ntawm tus pas tooj liab thiab xov nws rau hauv cov kav hlau, thiab tom qab ntawd sau nws nrog kev sib xyaw asphalt los ua ib txoj kab. Nws pw txoj kab hluav taws xob no hauv New York thiab sim xa xov xa hluav taws xob hauv av hluav taws xob. Xyoo tom qab, British Callender tsim lub suab-impregnated ntawv-insulated fais fab cable. Xyoo 1889, Tebchaws Askiv SZ Ferranti tau teeb tsa 10 kV roj-impregnated ntawv insulated cable ntawm London thiab Dartford. Xyoo 1908, Tebchaws Askiv tsim lub 20 kV cable network. Cov xaim hluav taws xob tau siv ntau dua thiab dav dua. Xyoo 1911, Lub Tebchaws Yelemees tau pib txhim kho ntawm cov xaim hluav taws xob ntau los ntawm kev tso 60 kV high-voltage cables. Xyoo 1913, German M. Horchstedt tau tsim cov khoom tiv thaiv-theem tiv thaiv cable, uas txhim kho hluav taws xob sib faib khoom sab hauv sab hauv cable thiab tshem tawm cov kev ntxhov siab ntawm lub ntsej muag insulating, uas tau dhau los ua ib qho tseem ceeb hauv kev txhim kho ntawm cov xaim hluav taws xob. Xyoo 1952, Sweden tso 380 kV ultra-high voltage cables nyob rau sab qaum teb fais fab nroj tsuag, paub qhov tseeb ntawm daim ntawv thov ntawm ultra-high voltage cable. Thaum xyoo 1980, 1100 kV thiab 1200 kV UHV fais fab cable tau tau ua.
