Xa Email19/33kV XLPE-insulated nruab nrab-voltage fais fab cables yog tsim rau lub zog sib txuas xws li chaw nres tsheb fais fab. Rau installation nyob rau hauv ducts, underground thiab sab nraum zoov. Nws kuj tseem tuaj yeem ua haujlwm rau kev teeb tsa ruaj khov hauv kev faib khoom sib txuas, chaw tsim khoom, thiab chaw nres tsheb fais fab. Thov nco ntsoov: Liab sab nrauv tuaj yeem ua rau fading thaum raug UV rays. Cov kab hluav taws xob nruab nrab yog tsim los siv cov txheej txheem monosil. Peb muab cov nroj tsuag tshwj xeeb, cov chaw tshawb fawb hauv lub xeev thiab cov txheej txheem tswj xyuas kom zoo uas yuav tsum tau ua rau kev tsim cov PVC insulated cables siv txog li 6KV thiab XLPE / EPR insulated cables rau kev siv ntawm voltages txog 35 KV. Cov ntaub ntawv yog tag nrho khaws cia rau hauv kev huv-tswj tej yam kev mob thoob plaws hauv cov txheej txheem ntau lawm thiaj li yuav xyuas kom meej lub homogeneity ntawm cov ntaub ntawv rwb thaiv tsev tiav.
