Lub npe ntawm cov khoom siv hlau thiab cable ua raws li cov hauv qab no:
Cov ntsiab lus suav nrog hauv Cov Khoom Npe
Cov khoom siv rau daim ntawv thov lossis cov khoom lag luam dav dav;
Cov khoom tsim cov khoom siv lossis hom;
Cov khoom lag luam cov yam ntxwv tseem ceeb lossis cov yam ntxwv ntxiv.
Feem ntau, cov khoom lag luam muaj npe raws li cov lus teev tseg saum toj no; Txawm li cas los xij, txhawm rau hais txog qhov tseem ceeb lossis cov yam ntxwv ntxiv, cov yam ntxwv no qee zaum muab tso rau ntawm qhov pib ntawm lub npe lossis tam sim ntawd ua ntej cov lus piav qhia ntawm cov qauv sib xws.
Ib theem zuj zus ntawm cov lus piav qhia
Cov txheej txheem piav qhia ntawm cov khoom ua raws li "sab hauv- tawm" ntu: Tus neeg xyuas pib → Rwb thaiv tsev → Inner Sheath → Outer Sheath → Armor Type.
Yooj yim
Hauv qhov xwm txheej uas ua li ntawd yuav tsis ua rau muaj kev ntxhov siab, qee qhov kev piav qhia ntawm cov qauv yuav raug tshem tawm lossis luv luv. Piv txwv li, txij li kev siv aluminium conductors raug txwv nyob rau hauv tsheb thaiv thiab cov hlua hloov tau yooj yim, cov khoom siv hluav taws xob feem ntau tsis tau teev tseg hauv lawv cov npe khoom.
