Lub tsev kev ruaj ntseg Circuit Court yuav tsum tsis txhob xaiv los ntawm cable loj xwb. Txoj kev cable, kev pheej hmoo hluav taws, kev tswj cov pa luam yeeb, thiab kev ua haujlwm hauv Circuit Court txhua qhov teeb meem. Ib qho hluav taws xob hluav taws xob hluav taws xob feem ntau yog siv rau cov khoom siv hluav taws xob uas yuav tsum tau ua haujlwm thaum lub sijhawm ntsuas hluav taws. Cov teeb pom kev kub ntxhov, cov twj tua hluav taws, cov kiv cua tawm pa, thiab lub tswb hluav taws xob hluav taws xob yog cov piv txwv. Lub tshav kub resistant fais fab cable yog txawv. Nws yog siv nyob rau hauv qhov chaw nyob ze ntawm lub tshav kub thaum lub sij hawm ib txwm ua hauj lwm, xws li qhov cub, cua sov, chav fais fab, thiab cov txheej txheem khoom.
Thawj kauj ruam yog los xyuas lub luag hauj lwm hauv Circuit Court. Yog tias lub Circuit Court yuav tsum muab cov khoom siv hluav taws xob, yuav tsum tau tshuaj xyuas qhov hluav taws kub. Cov ntaub ntawv siv cable suav nrog IEC 60331 ntawm 750 C rau tsawg kawg 90 feeb thiab UL 2196 ntawm 950 C rau tsawg kawg 180 feeb. Yog tias qhov kev txhawj xeeb tseem ceeb yog cov pa luam yeeb hnyav hauv thaj chaw pej xeem, qis - pa taws halogen- cov khoom siv dawb yuav tsum raug txiav txim siab. IEC 61034 thiab IEC 60754 cov lus qhia feem ntau yog siv los tham txog kev coj cwj pwm ntawm cov pa luam yeeb thiab kua qaub.
Kub yog lwm lub ntsiab lus. Qee qhov cua sov- cov kab hluav taws xob tiv thaiv tau teev nrog ntev - lub sijhawm ua haujlwm txog li 150 C thiab luv luv -lub sijhawm kub txog 180 C. Qhov no tsis tau txhais hais tias txhua lub cable tuaj yeem siv hluav taws xob ncaj qha. Nws txhais tau hais tias cov rwb thaiv tsev thiab sheath yuav tsum sib phim rau kev ua haujlwm kub nyob ib ncig ntawm txoj kab.
