YJV thiab BVV cov xov tooj tuaj yeem hais tias muaj qib siab ntawm kev sib koom ua ke hauv ntau yam. Piv txwv, hauv daim ntawv thov siv tau, ob lub YJV thiab BVV cov xov tooj feem ntau siv hauv kev teeb pom kev sab nraum zoov. Ob leeg kuj tseem siv tau los xa hluav taws xob. YJV cable thiab BVV cable muaj ntau qhov sib txawv ntawm cov teeb liab, qhov hluav taws xob thiab yam ntxwv.
Ua ntej, cia' qhia luv luv qhia YJV cable thiab BVV cable:
BVV cable lub npe tag nrho: tooj liab tub ntxhais PVC insulated PVC sheathed round sheathed cable
YJV cable lub npe tag nrho: XLPE insulated thiab PVC sheathed fais fab cable
Txawm hais tias YJV cable thiab BVV cable muaj qib siab ntawm kev sib tshooj hauv cov ntawv thov, muaj qhov ua tau qee qhov sib txawv ntawm ob. Thawj yog qhov sib txawv ntawm qhov hluav taws xob. Cov theem hluav taws xob ntawm BVV yog 300/500V, thaum qib hluav taws xob ntawm YJV cable yog ib txwm muaj. Peb lub zog: qis hluav taws xob 0.6/1KV, nruab nrab qhov hluav taws xob 6/10KV, qhov hluav taws xob siab 26/35KV, thiab lwm yam.
Qhov thib ob, sab txheej ntawm YJV cable thiab BVV cable sib txawv. BVV sheath hlau yog nquag siv cable hauv qhov ua haujlwm tsis muaj zog tam sim no. Nws cov qauv tsim los ntawm ob lossis ntau BV xov tooj ntxiv rau txheej txheej txheej sab nrauv. Cov tub ntxhais yog kab hlau, ob chav tub ntxhais yog xaim ncaj, thiab muaj 3 cores, 4 cores, 5 cores, 3-1 cores, 3-2 cores, 6 cores, 7 ~ 24 cores thiab lwm yam kev qhia tshwj xeeb. YJV yog tus ntoo khaub lig-txuas cable, thiab nws cov qauv yooj yim yog tsim los ntawm peb ntu: tus neeg xyuas pib, rwb thaiv tsev, thiab hnab looj tes. Yog tias muaj qhov tshwj xeeb xav tau, YJV cable tseem yuav muaj txheej tiv thaiv lossis txheej txheej tiv thaiv, thiab lwm yam, thiab tus lej cores, YJV piv nrog hom BVV. Ob peb, tsuas yog ib leeg xwb, 2 cores, 3 cores, 4 cores, 5 cores, 4-1 core, 3-2 core, 3-1 core.
Ib qho ntxiv, hais txog cov yam ntxwv, BVV cables thiab YJV cables kuj txawv. BVV yog ib qho khoom siv txhim kho tsev zoo. Nws cov yam ntxwv muaj cov yam ntxwv zoo xws li tiv taus xeb, tiv taus ya raws, thiab tiv taus roj, uas tsim nyog rau tsev neeg siv. Nws qhov kub ua haujlwm tsis tuaj yeem tshaj 65 degrees Celsius. Kev lig kev cai txhais tias yog lub hwj chim cable, nws tuaj yeem ua haujlwm ib txwm nyob hauv ib puag ncig uas tsis tshaj 90 degrees Celsius, muaj hluav taws xob ua tau zoo, thiab tseem muaj cov yam ntxwv zoo xws li kev ruaj ntseg, lub cev nyhav, thiab cov kab sab nraud me.
Txawm hais tias hauv ntau qhov kev thov, BVV thiab YJV tuaj yeem ua tau raws li qhov xav tau ntawm kev siv tib lub sijhawm, vim tias muaj qhov sib txawv ntawm ob, ntau qhov kev siv tshwj xeeb kuj txawv. Piv txwv li, BVV cov xov hluav taws xob tsim nyog rau lub zog ntsuas hluav taws xob 300/500V Nws tau siv los teeb tsa cov hlua hluav taws xob rau cov khoom siv hluav taws xob thiab hauv qab no, thiab feem ntau siv rau cov xaim hluav taws xob saum npoo av, xws li tso khoom siv hauv tsev, teeb pom kev zoo, thiab khoom siv hluav taws xob. YJV cov xov hluav taws xob tsim nyog rau kev teeb tsa ruaj khov hauv kev faib khoom sib txuas lossis kev teeb tsa kev lag luam nrog ntsuas lub zog hluav taws xob zaus ntawm 0.6/1KV thiab siab dua, xws li kev teeb tsa ruaj khov hauv nroog lub zog hluav taws xob, cov mines, thiab cov chaw tsim khoom loj.
Nws yog qhov tseeb vim tias kev txhim kho kev tshawb fawb thiab thev naus laus zis uas ntau yam kev lag luam tau koom nrog ntau dua thiab ntau qhov chaw thiab ntau thiab ntau qhov xav tau. Txhawm rau kom ua haujlwm tau zoo dua, cov xov hlau thiab cov xov hlau yuav tsim ntau yam khoom lag luam nrog cov yam ntxwv sib txawv thiab cov qauv. Cov yam ntxwv tshwj xeeb thiab siv cov txheej txheem ntawm cov khoom siv cable tuaj yeem siv qhov zoo tshaj plaws ntawm lawv cov ntaub ntawv thiab muab kev ua si rau lawv tus yam ntxwv zoo tshaj plaws thiab qhov zoo.
