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.
Txheem:
Xyoo 1418—South AfricanNational Standard for Aerial Bundled Conductors System
GENERAL CHARACTERISTIS:
Kev ntsuas hluav taws xob: 4 kV ac (5 min.)
Qhov ntsuas kub siab tshaj plaws ntawm tus neeg xyuas pib: +90 ºC
Short-Circuit kub ntawm tus neeg xyuas pib: 250 ºC (t ≤5s)
Qhov siab tshaj plaws rub lub zog tshaj tus neeg xyuas pib (N): tshaj tus neeg xyuas pib 30 x Seem mm²
Kev tsim kho:
TSEV KAWM NTAWV SYSTEM: Muaj plaub cores ntawm hard drawn stranded compactedaluminium conductorsntawm tib qhov chaw hla ntu insulated nrog carbon loaded XLPE rau UV tiv thaiv
TXOJ CAI TSHAJ PLAWS: Muaj peb theem cores ntawm cov khoom siv nyuaj ntawm cov khoom siv sib xyaw ua ke ntawm cov khoom sib txuas ntawm tib qho chaw sib txuas nrog cov pa roj carbon loaded XLPE thiab nteg ib ncigliab qab aluminium alloy txhawb core
