Cov khoom ntawm DC lub zog qaum mas yog muaj txheej txheem txheej, ib sab hauv, thiab tus neeg xyuas pib. Ntau hom kev kis kab mob muaj xws li tooj hlau thiab txhuas hlau.
1, txheej khaub ncaws
Cov txheej txheej txheej txheej no tseem hu ua kev tiv thaiv kabmob. Nws yog txheej txheej ntawm DC lub hwj huam hluav taws xob. Qhov kev pabcuam no yog siv los tiv thaiv kabmob DC. Cov txheej txheej muaj zog txaus, xws li kub kub thiab ua haujlwm. Tsawg kub, tsis kam mus rau lub teeb ci ntsa iab, kev ua haujlwm zoo, kev ua haujlwm siab thiab kev ua haujlwm zoo.
Pooj Txuj Ci: Lub tais khoob no tseem hu ua insulating sheath. Nws yog ib qho tseem ceeb ntawm ib nrab ntawm DC lub zog qaum. Lub hom phiaj tseem ceeb ntawm insulating sheath yog rwb thaiv tsev, txav lub hwj huam ntawm DC lub zog fais fab thiab cia lub tooj hlau xaim thiab cua tsis ncaj qha Tsis muaj cov leakage yuav tshwm sim, thiab cov khoom ntawm cov hlua khi insulating yuav tsum muag kom paub meej tias nws zoo kos rau hauv nruab nrab txheej.
2, sab hauv
Lub tais txheej txheem yog ib txheej ntawm cov khoom uas npuaj kab rau ntawm cov ntaub thaiv npog thiab cov tub ntxhais, feem ntau cov tshuaj polyvinyl chloride los yog polyethylene yas. Kuj muaj cov ntaub ntawv tsis muaj pa taws tsawg. Ua raws li cov txheej txheem cov cai, xwv txheej tiv thaiv yuav tsis tuaj rau hauv dej, cua los yog lwm yam khoom, thiab lub rwb thaiv tsev yuav tsum muaj kev tiv thaiv los ntawm cov dej noo thiab lub rwb thaiv tsev yuav raug pov thaiv los ntawm kev puas tsuaj.
3, tooj liab hlau
Lub xaim tooj liab yog qhov tseem ceeb ntawm DC lub zog xaim. Lub xaim tooj liab tsuas yog cov cab kuj tam sim no thiab cov khoom hluav taws xob. Qhov ceev ntawm tus tooj liab hlau ncaj qha mus cuam tshuam qhov zoo ntawm DC fais fab kab. Cov khoom siv ntawm DC lub zog qaum kuj yog ib qho tseem ceeb hauv kev tswj kom zoo. Tus lej thiab yooj yim ntawm txoj hlua tooj liab kuj pom tias tseem ceeb.
