Lub ntsiab kev faib tawm ntawm cov fais fab cables

Lub hwj chim cables ntawm lub Hoobkas cable yog tsuas yog siv rau kev sib kis thiab kev faib hluav taws xob hluav taws xob. Fais fab cables feem ntau yog siv rau cov kab hluav taws xob hauv nroog hauv av hauv av thiab chaw nres tsheb fais fab, nrog rau cov khoom siv hluav taws xob sab hauv ntawm kev lag luam thiab kev lag luam mining, los yog lub teb chaws underwater kis kab. Nyob rau hauv ib txoj kab, qhov kev faib ua feem ntawm cables kuj maj mam nce. Fais fab cable yog ib yam khoom siv cable siv los xa thiab faib cov hluav taws xob hluav taws xob siab hauv cov kab tseem ceeb ntawm lub zog hluav taws xob, suav nrog ntau theem voltage ntawm 1 ~ 500kv thiab siab dua, thiab ntau yam insulated fais fab cables. Lub hwj chim cable muaj keeb kwm ntau pua xyoo.

Nws yog Edison ntawm Tebchaws Meskas uas tau qhwv jute hauv Tongfeng County xyoo 1879 thiab muab tso rau hauv cov kav hlau, thiab tom qab ntawd muab ntim rau hauv ib lub cable uas ua los ntawm asphalt sib tov, thiab muab cov cable tso rau hauv New York los tsim ib lub khw muag ntawv hauv av. Nyob rau hauv lub xyoo thib ob, British Callender tsim pitch-impregnated ntawv insulated fais fab cables. Raws li qib voltage, nws tuaj yeem muab faib ua qis thiab nruab nrab fais fab cables, high voltage cables, ultra high voltage cables thiab ultra high voltage cables. Tsis tas li ntawd, nws tuaj yeem muab faib ua kev sib txuas lus cables thiab DC cables raws li tam sim no.

Yog tias nws muab faib raws li cuaj cov ntaub ntawv raw, nws tuaj yeem muab faib ua cov ntawv roj-impregnated. Insulated fais fab cable yog tsuas yog insulated los ntawm roj-impregnated ntawv. Keeb kwm ntawm kev siv fais fab cables hauv lub Hoobkas cable yog ntev heev, thiab nws muaj kev nyab xeeb thiab txhim khu kev qha. Ntev, tus nqi qis heev, ib qho tsis xws luag yog tias cov xim ntawm daim tawv nqaij raug txwv los ntawm kev poob. Txij li thaum txoj kev loj hlob ntawm non-drip impregnated ntawv rwb thaiv tsev, qhov teeb meem ntawm kev poob qis kuj tau daws nrog. Cov roj-impregnated ntawv insulated cable tau txuas ntxiv siv dav.

Yas insulated fais fab cable, nws cov rwb thaiv tsev txheej yog extruded yas fais fab cable. Cov yas siv feem ntau suav nrog poly-cov ntaub ntawv thiab ethylene-poly cross-linking. Raws li qee cov yas cables, cov qauv yooj yim heev, kev tsim khoom thiab kev ua haujlwm kuj yooj yim heev, thiab qhov hnyav hnyav heev. , Kev tso thiab kev teeb tsa yooj yim dua, thiab yuav tsis raug txwv los ntawm kev tso tawm. Yog li nws yog dav siv los ua ib qho nruab nrab thiab tsis tshua muaj hluav taws xob cable, thiab nws kuj tau hloov cov qauv ntawm cov ntawv nplaum nplaum.

Qhov tsis xws luag hauv cov txheej txheem yog qhov tshwm sim ntawm cov ceg tawg, uas tseem txwv nws txoj kev siv hluav taws xob ntau dua. Lub insulating txheej ntawm cov roj hmab insulated fais fab cable yog ua los ntawm roj hmab ntxiv rau ntau yam compounding agents. Tom qab sib tov txaus, nws yog extruded rau ntawm lub conductive hlau core los ntawm cua sov thiab vulcanizing kom nws mos mos thiab elastic. Yog li ntawd, nws yog haum rau mobile zaus thiab qee zaus nrog me me dabtsi yog khoov vojvoog.
