Txoj Kev Xaiv Cov Tub Ntxhais: Hlau Conductors
Lub "lub plawv" ntawm ib qho hlau lossis cable yog nws cov khoom siv hluav taws xob -ib qho tseem ceeb xws li cov ntshav ntws los ntawm peb cov leeg. Cov kev xaiv tseem ceeb tam sim no suav nrog:
Copper Conductors: Muaj cov khoom siv hluav taws xob zoo tshaj plaws thiab kev ua kom zoo dua qub, ua rau lawv zoo tagnrho rau cov ntawv thov uas yuav tsum tau khoov ntau zaus.
Aluminium Conductors: Lub teeb yuag thiab tus nqi- siv tau, cov no nquag siv nyob rau hauv ntev -span overhead power line.
Copper-Clad Aluminium: Muab qhov zoo ntawm ob qho tib si hlau; txheej txheej tooj liab ua kom cov conductivity, thaum lub hauv paus aluminium core txo qhov hnyav.
Cov Khoom Siv Alloy: Cov qauv tsim tshwj xeeb uas txhim khu kev tiv thaiv corrosion, ua rau lawv haum rau qhov chaw tshwj xeeb xws li cov nroj tsuag tshuaj.
Kev Tiv Thaiv Kev Tiv Thaiv: Cov Txheej Txheem Txheej Txheem
Cov txheej rwb thaiv tsev encasing tus neeg xyuas pib ua zoo li cov khaub ncaws tiv thaiv- nws yuav tsum ua raws li hluav taws xob thaiv thaum tib lub sijhawm ua kom ruaj khov:
Cov khoom siv PVC: Kev xaiv kev lag luam thiab siv tau zoo, muab cov nplaim hluav taws zoo- cov khoom tsis zoo thiab kev ua haujlwm yooj yim.
Polyethylene: Cov yam ntxwv los ntawm qhov tsis tshua muaj hluav taws xob poob, ua rau nws tshwj xeeb zoo - haum rau siab - zaus teeb liab kis tau tus mob.
Roj Hmab-raws li cov ntaub ntawv: khav theeb zoo elasticity, ua rau lawv qhov kev xaiv zoo tshaj plaws rau cables siv hauv cov khoom siv txawb.
Hla - Cov Khoom Txuas Txuas: Pom zoo thermal stability, muaj peev xwm tiv taus kev ua haujlwm siab dua.
Multifaceted Lub Hom Phiaj ntawm Sab Nraud Sheath
Lub tsho sab nraud ua haujlwm raws li lub xov tooj ntawm "cov cuab yeej" ua haujlwm nrog kev tiv thaiv kev tiv thaiv:
PVC Sheaths: Muaj kev tiv thaiv zoo - puag ncig, muaj peev xwm tiv taus kev puas tsuaj dav dav.
Cov Khoom Siv Polyurethane: Feature tshwj xeeb rau kev puas tsuaj, ua rau lawv haum rau qhov chaw hnyav xws li kev ua haujlwm mining.
Tsawg-Phau luam yeeb, Halogen- Cov Khoom Siv Dawb: Tsim cov pa luam yeeb tsawg heev thaum hlawv, ua rau lawv muaj kev nyab xeeb rau kev siv hauv cov chaw pej xeem.
Hlau Braided Layers: Muab ib txheej ntxiv ntawm electromagnetic shielding, tiv thaiv cov teeb liab los ntawm kev cuam tshuam sab nraud.
