Xa EmailMedium Voltage aerial bundled cables yog siv raucov kab hauv nruab nrabntawm ncej lossis raws li feeders rau thaj chaw nyob. Kuj tseem ua haujlwm rau kev xa hluav taws xob los ntawm cov ncej hluav taws xob mus rau cov tsev. Muab kev nyab xeeb thiab kev ntseeg siab, nws tiv taus huab cua hnyav, hluav taws xob ultraviolet, thiab kev ntxhov siab txhua yam. Yooj yim rau nruab thiab tswj, nrog rau cov nqi ua haujlwm qis, nws nquag siv rau kev faib hluav taws xob hauv nroog thiab nyob deb nroog.
Txheem:
IEC 60502-2---- Fais fab cables nrog extruded rwb thaiv tsev thiab lawv cov khoom siv rau cov ntsuas hluav taws xob los ntawm 1 kV (Um = 1.2 kV) txog 30 kV (Um = 36 kV) - Ntu 2: Cables rau cov ntsuas hluav taws xob ntawm 6 kV (Um = 7.2 kV) m3 (Um = 7.2 kV) m3
