Dab tsi yog Cov Khoom Tseem Ceeb Ntawm Cov Hluav Taws Xob Cables?

Raws li qhov voltage:
Raws li qib voltage, nws tuaj yeem muab faib ua nruab nrab thiab qis hluav taws xob hluav taws xob cables (35 kV thiab qis dua), high voltage cables (siab dua 110 kV), ultra-high voltage cables (275-800 kV) thiab ultra-high voltage. cables (1000 kV thiab siab dua). Tsis tas li ntawd, nws tuaj yeem muab faib ua AC cables thiab DC cables raws li qhov system tam sim no.
Raws li cov ntaub ntawv rwb thaiv tsev:
1. Roj-impregnated ntawv insulated fais fab cable yog lub hwj chim cable insulated nrog roj-impregnated ntawv. Nws muaj daim ntawv thov ntev tshaj plaws. Nws muaj kev nyab xeeb thiab txhim khu kev qha, muaj lub neej ua haujlwm ntev thiab pheej yig. Lub ntsiab qhov tsis zoo yog qhov tso tawm yog txwv los ntawm kev poob. Txij li thaum txoj kev loj hlob ntawm drip-dawb impregnated ntawv rwb thaiv tsev, qhov poob txwv qhov teeb meem tau raug daws, cia cov roj-impregnated ntawv insulated cables mus txuas ntxiv tau dav siv.
2. Yas insulated fais fab cable Cov txheej rwb thaiv tsev yog ib qho extruded yas fais fab cable. Cov yas siv feem ntau yog polyvinyl chloride, polyethylene, thiab cross-linked polyethylene. Yas cables muaj cov qauv yooj yim, yooj yim rau kev tsim thiab txheej txheem, yog lub teeb hauv qhov hnyav, yooj yim rau nteg thiab nruab, thiab tsis txwv los ntawm kev tso tawm. Yog li ntawd, lawv tau dav siv los ua cov kab nruab nrab thiab tsis tshua muaj hluav taws xob, thiab muaj qhov sib txawv los hloov cov ntaub ntawv roj nplaum nplaum nplaum. Nws qhov tsis zoo tshaj plaws yog qhov dendrite tawg tshwm sim, uas txwv nws txoj kev siv ntawm cov hluav taws xob ntau dua.
3. Roj hmab insulated fais fab cable Cov txheej rwb thaiv tsev yog cov roj hmab ntxiv rau ntau yam sib xyaw ua ke, uas yog tag nrho sib xyaw thiab extruded rau ntawm cov tub ntxhais conductive thiab ces rhuab thiab vulcanized. Nws yog mos thiab elastic, haum rau lub sijhawm uas nquag txav thiab me me dabtsi yog khoov vojvoog.
Cov khoom siv roj hmab feem ntau siv rau kev rwb thaiv tsev xws li roj hmab-styrene-butadiene roj hmab sib xyaw, ethylene-propylene roj hmab, butyl roj hmab, thiab lwm yam.
