Kev tswj cov kab hluav taws xob yog cov yam ntxwv los ntawm kev ya raws, kev tiv thaiv corrosion, thiab kev puas tsuaj, thiab tuaj yeem muab tso rau hauv qhov tunnels lossis cable trench. Cov kab hluav taws xob hluav taws xob tau siv rau hauv cov kab hluav taws xob tseem ceeb los xa tawm thiab xa tawm siab - lub zog hluav taws xob hluav taws xob, thaum tswj cov cables ncaj qha xa hluav taws xob hluav taws xob los ntawm cov ntsiab lus xa mus rau cov khoom siv hluav taws xob ntawm ntau yam khoom siv hluav taws xob thiab cov khoom siv hluav taws xob. Qhov ntsuas hluav taws xob ntawm lub zog hluav taws xob feem ntau yog 0.6 / 1kV thiab siab dua, thaum tswj cov kab hluav taws xob feem ntau yog 450 / 750V. Thaum lub sij hawm tsim khoom, cov hluav taws xob cables muaj cov rwb thaiv tsev tuab dua thiab cov sheaths dua li kev tswj cov kab hluav taws xob ntawm tib cov lus qhia.
Cov kab hluav taws xob tswj tau yog cov khoom siv hluav taws xob cables, thiab nrog rau cov hluav taws xob cables, lawv yog ob ntawm tsib pawg loj cable.
Tus qauv rau kev tswj cov cables yog GB 9330, thaum tus qauv rau fais fab cables yog GB 12706.
Lub rwb thaiv tsev ntawm cov cables tswj feem ntau yog xim dub nrog cov ntawv dawb, thaum qis -voltage fais fab cables feem ntau yog xim -coded.
Tus ntoo khaub lig- thaj tsam ntawm kev tswj cov kab hluav taws xob feem ntau tsis pub tshaj 10 square millimeters, thaum fais fab cables, feem ntau yog xa hluav taws xob, feem ntau muaj cov ntoo khaub lig loj dua -sections.
Rau cov laj thawj uas tau hais los saum toj no, cov kab hluav taws xob feem ntau tuaj yeem muaj tus ntoo khaub lig loj dua - ntu, txog li 500 square millimeters (qhov ntau yam uas cov tuam txhab lag luam tuaj yeem tsim tau). Muaj cov chaw tsim khoom tsawg dua uas tuaj yeem tsim cov ntoo khaub lig- ntu loj dua qhov ntawd. Kev tswj cov kab hluav taws xob, ntawm qhov tod tes, feem ntau muaj me me hla- ntu, nrog qhov siab tshaj plaws tsis pub tshaj 10 square millimeters.
