1. Outer sheath:
Lub tsho sab nrauv, tseem hu ua lub tsho tiv thaiv, yog lub tsho sab nraud ntawm cov hlua hluav taws xob. Cov txheej txheej no muaj cov yam ntxwv muaj zog xws li kub tsis kam, tsis kub tsis kam, tsis kam tiv thaiv hluav taws xob cuam tshuam, kev ua haujlwm dav dav, kev ua haujlwm ntev, thiab cov ntaub ntawv zoo ib puag ncig.
2. Lub tes tsho insulating:
Lub tes tsho insulating, tseem hu ua insulating sheath, yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob. Lub luag haujlwm ntawm lub insulating sheath yog insulate, los xyuas kom meej lub hwj chim txuag kev ruaj ntseg ntawm lub hwj chim kab, thiab kom tsis txhob muaj qhov to ntawm tooj liab xov hlau thiab huab cua, tab sis cov khoom ntawm insulating sheath yuav tsum mos mos los xyuas kom meej tias nws yuav tsum tau embedded nyob rau hauv cov ntaub ntawv. nruab nrab txheej.
3. Tooj hlau:
Cov hlau tooj liab yog qhov tseem ceeb ntawm lub zog xaim. Qhov zoo ntawm cov xaim tooj liab yuav cuam tshuam ncaj qha rau tam sim no thiab qhov hluav taws xob ntawm lub zog xaim. Nws yog ib qho tseem ceeb heev los xyuas kom meej tias qhov zoo ntawm cov tooj liab hlau ua tau raws li qhov yuav tsum tau ua thiab cov lus qhia tshwj xeeb ntawm lub zog xaim. Tsis tas li ntawd, qhov kom muaj nuj nqis thiab kev hloov pauv ntawm cov hlau tooj liab kuj yog qhov tseem ceeb rau kev xav.
4. Inner sheath:
Cov ntaub qhwv sab hauv yog ib txheej ntawm cov khoom siv qhwv ntawm cov ntaub thaiv npog ntawm cov hlua hluav taws xob thiab cov tub ntxhais hlau, feem ntau polyvinyl chloride yas lossis polyethylene yas, thiab tseem muaj cov pa taws tsawg. Raws li cov kev qhia tshwj xeeb ntawm cov txheej txheem tsim khoom, cov txheej txheem insulating yuav tsum tsis txhob tiv tauj dej, huab cua lossis lwm yam khoom kom tsis txhob muaj kev puas tsuaj rau cov txheej txheem insulating thiab txheej txheej insulating.
5. Tus coj:
Tus neeg xyuas pib yog ib qho tseem ceeb ntawm cov kab hluav taws xob. Lub luag haujlwm tseem ceeb ntawm tus neeg xyuas pib yog muab cov haujlwm sib kis. Nws yuav tsum tau txiav txim siab seb qhov zoo ntawm tus neeg xyuas pib ua tau raws li qhov xav tau tshwj xeeb.
