Xa EmailCables rau cov khoom siv hluav taws xob siv hluav taws xob feem ntau yog rau pej xeem kev faib tawm. Kev teeb tsa sab nraum zoov hauv cov kab nyiaj siv ua haujlwm nruj ntawm kev txhawb nqa, kab txuas rau façades. Kev tiv thaiv zoo rau cov neeg ua haujlwm sab nraud. Tsis haum rau installation ncaj qha underground. Kev faib tawm nyiaj siv ua haujlwm rau thaj chaw nyob, nyob deb nroog thiab nroog, xa thiab xa hluav taws xob los ntawm kev siv hluav taws xob los yog cov tsev. Muab piv rau cov tshuab hluav taws xob tsis muaj hluav taws xob tsis muaj hluav taws xob, nws muaj kev ruaj ntseg zoo dua, txo tus nqi teeb tsa, txo qis hluav taws xob thiab kev ntseeg tau ntau dua.
Txheem:
Xyoo 1418—South AfricanNational Standard for Aerial Bundled Conductors System
GENERAL CHARACTERISTIS:
Kev ntsuas hluav taws xob: 4 kV ac (5 min.)
