Kuv. Taw qhia ntawm FTH Networks
Nrog rau kev txhim kho kev sib txuas lus ntawm kev sib txuas lus thiab cov sib sib zog nqus ntawm kev nkag tau, FTHTTH Kev Siv Kev Siv Network tab tom loj hlob zuj zus.
Nyob rau tam sim no, Ob Suav Tuam Tshoj thiab Tuam Tshoj Netcom tau qhia tias lawv yuav tau nqis peev nyiaj ntau npaum li cas ntawm kev ua lag luam loj ntawm FTH.
Yog vim li cas thiaj tsis tau High-Voltage Cables yuav faus rau hauv av?
Dab tsi yog High-Voltage Cable?
Ultra-high voltage kis tau tus mob hais txog kev siv 500 kV-1000 kV voltage theem xa hluav taws xob.
Yog tias 220 kV kis tau tus mob index yog 100%, tus txheeb ze peev ib kilometer ntawm UHV kis tau tus mob, tus nqi txheeb ze ib kilowatt-teev hluav taws xob xa mus ib puas kilometers thiab kev noj cov khoom siv hlau, lwm yam., tau raug txo kom tsawg, thiab txoj kab hauv kev siv tus nqi tau raug txhim kho zoo.
Hauv peb lub neej txhua hnub, peb tuaj yeem pom cov nyiaj siv ua haujlwm ultra-high voltage kis tau tus mob project, seb peb puas tau xav txog cov lus nug: vim li cas ho tsis tuaj yeem zoo li lub nroog underground cable, high-voltage fais fab kab tag nrho faus underground?
Tseem ceeb! Yam Koj Yuav Tsum Paub Txog Lub Luag Haujlwm Ntawm Kev Tiv Thaiv Hauv Kev Tswj Cables
Ib shielded tswj cable feem ntau yog siv los ua cov kab txuas ntawm cov cuab yeej hluav taws xob.
Nws yog qhov tsim nyog rau kev sib txuas ntawm cov cuab yeej hluav taws xob nrog AC-rated voltage ntawm 450/750V thiab hauv qab no thiab cov kab sib txuas ntawm kev tswj tsis siv neeg.
Nws muaj cov khoom zoo xws li roj tsis kam, dej tsis kam, hnav tsis kam, acid thiab alkali tsis kam, tsis kam mus rau ntau yam corrosive gases, kev laus tsis kam, thiab tsis-combustibility.
Dab tsi yog Qhov Chaw Hluav Taws Xob?
Rau cov neeg niaj hnub nyob hauv ntau qhov chaw ntawm lub ntiaj teb, hluav taws xob yog qhov tsim nyog. Nws yog ib yam khoom tseem ceeb uas pab txhawb peb kev nplij siab. Peb cov hauj lwm, gadgets, thiab feem ntau cov dej num txhua hnub yog nyob ntawm peb lub peev xwm nkag tau hluav taws xob.
Daim ntawv thov thiab kev cia siab ntawm High Voltage DC Transmission Cable
Los ntawm kev xav thoob ntiaj teb, high-voltage DC kis tau tus mob cable yog siv rau cov cheeb tsam hauv qab no xws li qhov ntev-ntev high-capacity overhead transmission, hluav taws xob daim phiaj kev sib txuas, thiab deb deb submarine cable kis tau tus mob nrog pom tseeb zoo.
6 Cov yam ntxwv ntawm Braided Cable
Braided cables yuav tsum tau rau stability.
Hla threads cia lub braid mus flex thiab stretch yam tsis muaj dabtsi yog khoov, folding los yog kinking.
Muaj cov khoom siv hluav taws xob zoo heev braided cables thiab electrostatic shield los xyuas kom meej cov teeb liab.
Tooj liab, tinned tooj, thiab aluminium yog cov piv txwv ntawm cov conductors no.
