Cov txheej txheem ntawm kev tswj cov khoom siv cable feem ntau yog muab faib ua cov txheej txheem tseem ceeb ntawm tus neeg xyuas pib, txheej txheej insulating, thaiv thiab tiv thaiv txheej, nrog rau cov khoom ntim thiab ncab cov ntsiab lus. Raws li kev siv cov khoom siv thiab kev siv cov khoom, qee cov khoom siv tau yooj yim heev hauv cov qauv thiab yog cov qauv ntawm tus neeg xyuas pib, xws li tus neeg xyuas pib liab qab, tus neeg xyuas pib catenary, tooj liab txhuas tsheb npav ( npav), thiab lwm yam, Cov khoom siv hluav taws xob sab nraud ntawm cov khoom no. yog guaranteed los ntawm qhov chaw nyob deb ntawm lub insulator (xws li cua rwb thaiv tsev) thaum lub sij hawm installation thiab tso. Tom qab ntawd, cia peb saib cov qauv ntawm cov khoom tswj cable!
1. Tus coj
Cov hlau yog ib qho tseem ceeb ntawm cov khoom siv los xa cov ntaub ntawv tam sim no thiab electromagnetic yoj. Cov hlau yog cov ntawv luv ntawm cov tub ntxhais hlau conductive, uas yog ua los ntawm cov hlau tsis muaj hlau nrog cov conductivity zoo xws li tooj liab thiab txhuas. Optical fiber cable rau optical kev sib txuas lus network uas tau tsim sai heev nyob rau hauv lub dhau los 30 xyoo siv optical fiber raws li cov hlau.
2. Insulating txheej
Cov kab hluav taws xob tswj tau qhwv ib ncig ntawm tus neeg xyuas pib nrog cov khoom siv hluav taws xob, uas yog, cov khoom xa tawm tam sim no, electromagnetic yoj thiab lub teeb yoj tsuas tuaj yeem txav mus raws tus neeg xyuas pib thiab tsis tuaj yeem ntws mus rau sab nraud. Lub peev xwm ntawm tus neeg xyuas pib tuaj yeem txiav tawm, uas yog, qhov sib txawv muaj peev xwm tsim los ntawm cov khoom nyob ib puag ncig, uas yog, qhov voltage. Kev ua haujlwm ntawm tus neeg xyuas pib yuav tsum tau ua kom tiav, Tib lub sijhawm, txhawm rau kom muaj kev nyab xeeb ntawm cov khoom siv sab nraud thiab tib neeg lub cev, tus neeg xyuas pib thiab cov txheej txheem rwb thaiv tsev yog ob yam tseem ceeb uas yuav tsum muaj rau cov khoom siv cable uas tsis yog cov xov hlau liab qab.
3. txheej tiv thaiv
Thaum tswj cov kab hluav taws xob teeb tsa cov xov hlau thiab cables nyob rau hauv ntau qhov chaw rau kev ua haujlwm, nws yog ib qho tsim nyog los tiv thaiv tag nrho cov khoom, tshwj xeeb tshaj yog cov seem ntawm cov txheej rwb thaiv tsev, uas yog hu ua txheej tiv thaiv.
Raws li cov ntaub ntawv rwb thaiv tsev yuav tsum muaj cov khoom siv hluav taws xob zoo heev, lawv yuav tsum muaj cov purity siab thiab ob peb impurities; Feem ntau, nws tsis tuaj yeem muab kev txiav txim siab txog kev tiv thaiv lub peev xwm rau lub ntiaj teb sab nraud, yog li cov txheej txheem tiv thaiv ntau yam yuav tsum muaj kev tiv thaiv thiab kev tiv thaiv rau ntau lub zog ntawm lub ntiaj teb sab nraud (piv txwv li, teeb tsa, siv cov xwm txheej, thiab siv), atmospheric ib puag ncig tiv thaiv, tshuaj tiv thaiv thiab roj tsis kam, kev tiv thaiv kab mob lom, thiab txo kev puas tsuaj hluav taws.
Cov khoom siv cable feem ntau thiab cov ntaub ntawv insulating txheej nrog qee lub zog txhua yam thiab huab cua tsis kam, uas tshwj xeeb yog siv rau kev huv, qhuav, sab hauv tsev thiab lwm yam zoo sab nraud yam tsis muaj kev siv tshuab sab nraud, tuaj yeem tsis muaj cov khoom xws li cov txheej txheem tiv thaiv.
4. Kev tiv thaiv
Nws yog ib feem uas cais cov electromagnetic teb nyob rau hauv cov khoom cable los ntawm sab nraud electromagnetic teb; Cov khub sib txawv (lossis pawg) ntawm cov khoom siv cable hauv cov khoom siv cable yuav tsum raug cais tawm ntawm ib leeg. Cov txheej thaiv tiv thaiv tuaj yeem hais tau tias yog "kev tshuaj ntsuam electromagnetic cais".
