Qhov ua rau hluav taws los ntawm USB cables tuaj yeem xa mus rau 4 cov ntsiab lus hauv qab no:
1. Kev kub nyhiab ntawm lub taub hau cable: Vim yog qhov ntub dej thiab av ntawm qhov chaw ntawm lub taub hau cable, cov plooj (porcelain bushing) ntawm lub taub hau cable yog tawg thiab cov hlau lead me me dhau, ua rau flashover thiab hluav taws kub, ua rau cov rwb thaiv tsev ntawm cov nplaim hluav taws. lub taub hau cable thiab cov hlau lead hlau rwb thaiv tsev kom hlawv.
2. Kev ua txhaum luv luv los ntawm kev puas tsuaj los ntawm rwb thaiv tsev: Cov hlau lead tiv thaiv ntawm lub hwj chim cable puas thaum lub sij hawm tso los yog cov rwb thaiv tsev cable yog mechanically puas thaum lub sij hawm ua hauj lwm, uas ua rau lub rwb thaiv tsev puas ntawm cov cables los yog nruab nrab ntawm cov hlau lead sheaths. Cov txheej txheem tiv thaiv tau hlawv thiab ignited.
3. Rwb thaiv tsev ntawm qhov nruab nrab ntawm lub thawv sib koom: Lub hauv nruab nrab ntawm lub cable sib koom lub thawv tsis nruj nruj, welded los yog cov khoom sib koom ua ke raug xaiv tsis raug, qhov sib koom ua ke yog oxidized, rhuab, thiab glued thaum ua haujlwm; thaum ua cov cable nruab nrab sib koom ua ke, nws yog poured nyob rau hauv nruab nrab Qhov zoo ntawm cov insulating neeg sawv cev nyob rau hauv lub sib koom lub thawv tsis tau raws li qhov yuav tsum tau. Thaum tus neeg saib xyuas insulating yog nchuav, muaj qhov pores nyob rau hauv lub thawv thiab lub thawv cable tsis zoo kaw, puas, thiab ya raws. Cov yam ntxwv saum toj no tuaj yeem ua rau rwb thaiv tsev tawg, ua rau luv luv, thiab ua rau lub cable tawg thiab tawg.
4. Lub sij hawm ntev overloading ntawm lub cable: lub sij hawm ntev overloading, kev khiav hauj lwm kub ntawm lub cable rwb thaiv tsev cov ntaub ntawv tshaj qhov siab tshaj plaws tso cai kub ntawm ib txwm cua sov, thiab lub rwb thaiv tsev ntawm lub cable yog laus thiab qhuav. Qhov tshwm sim ntawm rwb thaiv tsev laus thiab ziab feem ntau tshwm sim ntawm tag nrho cov kab cable. . Vim qhov kev laus thiab dryness ntawm cov rwb thaiv tsev cable, cov khoom siv rwb thaiv tsev poob lossis txo qhov kev ua haujlwm ntawm cov rwb thaiv tsev thiab cov khoom siv hluav taws xob, yog li nws yog qhov ua rau hluav taws kub hnyiab, thiab txawm tias kub hnyiab thiab hluav taws tshwm sim ntawm ntau qhov chaw raws li tag nrho qhov ntev ntawm lub cable.
