Cov khoom tseem ceeb ntawm kev tswj cables niaj hnub no yog: polyvinyl chloride insulated tswj cables, ntuj styrene butadiene roj hmab insulated tswj cables, thiab polyethylene insulated tswj cables, ntxiv rau cov khoom uas txuas polyethylene rwb thaiv tsev thiab ethylene propylene roj hmab rwb thaiv tsev. Thaum ntxov zus tau tej cov roj impregnated ntawv insulated txhuas sheathed tswj cables tau phased tawm.
Kev ntsuas kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm kev tswj cov cables thiab tiv thaiv kev cuam tshuam.
Txhawm rau kom muaj kev ruaj ntseg ntawm kev tswj cov cables nyob rau hauv qhov xwm txheej ntawm rwb thaiv tsev nkag mus, kev puas tsuaj, lossis hluav taws kub, lub teb chaws kev lag luam tus qauv GB50217-91 "Code for Design of Cable Lines in Electric Power Construction Projects" qhia meej meej tias kev tswj xyuas cais. cables yuav tsum tau siv rau ob lub tshuab uas yuav tsum tau txhim khu kev ruaj ntseg, nrog rau kev tiv thaiv bidirectional tam sim no, ua hauj lwm voltage, DC stabilized fais fab mov, thiab mus txawv tebchaws tswj Circuit Court.
Tswj cable chaw tsim tshuaj paus - Tom qab cov tswj cable tau muab tso rau hauv kev ua haujlwm, cov khoom siv hluav taws xob cuam tshuam tshwm sim ntawm cov kab hluav taws xob sib txawv ntawm tib lub cable thiab nruab nrab ntawm cov kab sib txuas uas nyob ib sab. Lub hauv paus tseem ceeb ua rau cov khoom siv hluav taws xob cuam tshuam yog qhov tsim ntawm electrostatic cuam tshuam nyob rau hauv kev cuam tshuam ntawm sab nraud kev khiav hauj lwm voltage thiab lub coupling ntawm capacitors ntawm cores; Kev cuam tshuam los ntawm kev sib nqus ntawm cov hluav taws xob tam sim no. Zuag qhia tag nrho, thaum muaj hluav taws xob siab thiab loj tam sim no electromagnetic cuam tshuam nyob ib puag ncig, kev cuam tshuam ntawm cov khoom siv hluav taws xob ua kom pom ntau dua. Vim yog qhov me me ntawm cov kab hluav taws xob ntawm tib lub cable, qhov kev cuam tshuam ntawm kev cuam tshuam ntau dua li ntawm cov kab uas nyob ib sab.
