RJ Cable Quality Identification

Lub xeev tau txiav txim kom meej tias cov xov tooj tooj liab yuav tsum tau siv rau hauv cov tsev uas tau tsim tshiab. Txawm li cas los xij, kuj tseem muaj cov kab tooj liab tsis zoo. Cov tub ntxhais tooj liab yog ua los ntawm cov tooj liab rov ua dua thiab muaj ntau yam impurities. Qee cov xov tooj hlau tsis zoo yog qhov tsis tshua muaj hluav taws xob ntau dua li cov hlau hlau, uas tuaj yeem ua rau hluav taws xob raug mob. Muaj ntau ntau yam, specifications thiab nqi ntawm cov xov hlau nyob rau hauv kev ua lag luam, uas ua rau nws nyuaj rau cov neeg siv khoom xaiv. Tsuas yog saib tus nqi ntawm ob hom tooj liab core xov hlau, 2.5 square millimeters thiab 4 square millimeters, uas feem ntau siv rau hauv tsev kho kom zoo nkauj, tus nqi ntawm ib co coil ntawm cov xov hlau ntawm tib lub specification tuaj yeem sib txawv ntawm 20% ~ 30% vim rau txawv manufacturers. Raws li qhov zoo thiab seb qhov ntev npaum li cas raws li tus qauv, nws tseem nyuaj rau cov neeg siv khoom txiav txim.
Raws li kev lag luam sab hauv: Yog vim li cas vim li cas tus nqi sib txawv ntawm cov xov hlau loj yog vim cov khoom siv sib txawv siv hauv cov txheej txheem tsim khoom. Cov ntaub ntawv tseem ceeb rau kev tsim cov xov hlau yog electrolytic tooj liab, cov ntaub ntawv rwb thaiv tsev thiab cov ntaub ntawv sheath. Tus nqi ntawm electrolytic tooj liab nyob rau hauv lub lag luam raw khoom yog kwv yees li 50,{1}} yuan ib tuj, hos tus nqi ntawm recycled seem tooj liab tsuas yog hais txog 40,000 yuan ib tuj; tus nqi ntawm cov khoom zoo ntawm cov ntaub ntawv rwb thaiv tsev thiab cov ntaub ntawv sheath yog 8,000 txog 10,000 yuan ib tuj, thaum tus nqi ntawm cov khoom puas tsuas yog 4,000 rau 5. ,000 yuan ib tuj, thiab tus nqi sib txawv yog ntau dua. Tsis tas li ntawd, qhov ntev tsis txaus thiab tsis txaus cov ntsiab lus ntawm cov roj hmab hauv cov rwb thaiv tsev kuj tseem yog vim li cas rau tus nqi sib txawv. Qhov ntev ntawm txhua kauj ntawm cov hlau yog 100 meters rau cov khoom zoo, thaum tsuas yog li 90 meters rau cov khoom puas; cov roj hmab cov ntsiab lus ntawm rwb thaiv tsev yog 35% mus rau 40% rau cov khoom zoo, thaum tsuas yog 15% rau cov khoom puas. Los ntawm kev sib piv, nws tsis yog qhov nyuaj rau cov neeg siv khoom pom tias qhov sib txawv ntawm tus nqi muag khoom ntawm cov xov hlau tiav yog vim muaj kev dag ntxias hauv cov ntaub ntawv.
