Xa Ib Tsab EmailAluminium Concentric Cable tsim nyog rau kev siv hauv tsev, kev lag luam thiab kev lag luam, suav nrog kev nkag mus rau hauv tsev, cov khoom noj khoom haus thiab cov ceg ntoo. Cov xov hlau concentric yog siv ua hluav taws xobqhov rooj nkag kev pabcuamlos ntawm lub network faib hluav taws xob mus txog rau ntawm lub vaj huam sib luag 'meter' (tshwj xeeb tshaj yog qhov twg nws xav tau los tiv thaiv kev poob "dub" lossis kev nyiag hluav taws xob), thiab ua cov xov hlau pub los ntawm lub vaj huam sib luag 'meter' mus txog rau ntawm lub vaj huam sib luag lossis lub vaj huam sib luag faib hluav taws xob dav dav, ib yam li nws tau teev tseg hauv National Electrical Code. Hom kab hluav taws xob no tuaj yeem siv rau hauv qhov chaw qhuav thiab ntub dej, faus ncaj qha lossis sab nraum zoov. Nws qhov kub siab tshaj plaws ntawm kev ua haujlwm yog 90 ºC thiab nws qhov hluav taws xob ntawm kev pabcuam rau txhua daim ntawv thov yog 600V.
Cov txiaj ntsig:
Tshwj xeeb tshaj yog tsim rau kev sib txuas ib theem los ntawm cov kab hluav taws xob uas tau sib dhos ua ntej thiab muaj hluav taws xob tsawg, txo qhov kev pheej hmoo ntawm kev nyiag hluav taws xob. Kev teeb tsa yuav tsum tau siv cov kev tiv thaiv los ntawm huab cua uas raug qhib thaum muaj kev sib txuas luv luv vim yog kev sim txuas zais cia, cuam tshuam kev pub mov thiab qhia txog kev sim nyiag.
