Raws li qhov voltage:
Cov kab hluav taws xob muaj peev xwm muab faib ua cov kab nruab nrab thiab tsis tshua muaj hluav taws xob (35 kV thiab qis dua), cov kab hluav taws xob siab (siab tshaj 110 kV), ultra- cov kab hluav taws xob siab (275-800 kV), thiab ntxiv - cov kab hluav taws xob siab (1000 kV thiab siab dua). Lawv tuaj yeem raug cais los ntawm cov kab ke tam sim no rau hauv AC cables thiab DC cables.
Raws li cov khoom siv rwb thaiv tsev:
Roj-impregnated ntawv insulated fais fab cables: Fais fab cables nrog roj-impregnated ntawv rwb thaiv tsev. Lawv muaj keeb kwm ntev tshaj plaws ntawm daim ntawv thov. Lawv muaj kev nyab xeeb, txhim khu kev qha, muaj lub neej ua haujlwm ntev, thiab pheej yig. Lub ntsiab tsis zoo yog tias lawv cov installation yog txwv los ntawm qhov siab sib txawv. Txij li thaum txoj kev loj hlob ntawm cov ntaub ntawv uas tsis yog-drip impregnated ntawv rwb thaiv tsev, qhov nce qhov sib txawv ntawm cov teeb meem txwv tau raug daws, tso cai rau cov roj-impregnated ntawv insulated cables mus txuas ntxiv tau dav siv.
Yas insulated fais fab cables: fais fab cables nrog extruded yas rwb thaiv tsev. Cov yas siv feem ntau suav nrog polyvinyl chloride, polyethylene, thiab ntoo khaub lig- txuas polyethylene. Yas cables muaj cov qauv yooj yim, yooj yim rau kev tsim thiab txheej txheem, yog lub teeb yuag, thiab yooj yim rau nteg thiab nruab, tsis muaj kev txwv los ntawm kev nce qhov sib txawv. Yog li ntawd, lawv tau dav siv los ua cov kab nruab nrab thiab tsis tshua muaj hluav taws xob thiab tab tom tab tom hloov pauv cov ntawv nplaum impregnated ntawv cables. Nws qhov teeb meem loj tshaj plaws yog qhov muaj dendritic kev puas tsuaj, uas txwv nws txoj kev siv ntawm cov hluav taws xob ntau dua.
Roj Hmab- insulated fais fab cables: Lub rwb thaiv tsev txheej yog ua los ntawm roj hmab nrog ntau yam additives, uas yog sib xyaw kom huv si thiab extruded mus rau lub conductive core, ces vulcanized ntawm kub. Nws yog mos thiab elastic, haum rau daim ntaub ntawv nrog nquag txav thiab me me bending radii.
