Raws li tus neeg xyuas pib ntawm lub zog xa hluav taws xob thiab kev xa tawm thiab kev lag luam hluav taws xob faib hluav taws xob, kev xaiv ntawm cov khoom siv tooj liab busbar ncaj qha cuam tshuam rau cov khoom siv hluav taws xob, lub zog siv hluav taws xob, kev tiv thaiv corrosion, thiab ntev - lub sijhawm ua haujlwm kev ntseeg tau. Kev xaiv tsim nyog ntawm hom tooj liab thiab purity, ua ke nrog kev kho qhov chaw tsim nyog thiab kev tswj cov txheej txheem, yog qhov yuav tsum tau ua ua ntej kom ua tiav kev sib kis tau zoo thiab muaj kev nyab xeeb raws li qhov sib txawv ntawm daim ntawv thov thiab cov kev cai.
Cov khoom siv yooj yim rau tooj liab busbars yog electrolytic tooj liab, uas nws purity thiab cov qauv sab hauv txiav txim siab qhov tseem ceeb ntawm kev ua tau zoo. Cov khoom siv tooj liab feem ntau suav nrog siab-purity electrolytic tooj liab (purity Ntau dua lossis sib npaug li 99.90%), oxygen-dawb tooj liab (OFC, tsis tshua muaj oxygen cov ntsiab lus), thiab qis- oxygen tooj liab. High-purity electrolytic tooj liab muaj ib tug conductivity nyob ze rau nws theoretical tus nqi thiab yog haum rau siab -tam sim no daim ntaub ntawv uas tsis tshua muaj yuav tsum nruj heev rau kab poob thiab kub nce, xws li substation lub ntsiab busbars thiab loj muaj hwj chim faib trunk kab. Oxygen-dawb tooj liab, vim nws tswj nruj me ntsis cov ntsiab lus ntawm cov pa oxygen thiab cov qauv zoo li qub, ua pov thawj zoo dua ductility thiab weldability. Nws yog feem ntau siv hauv cov khoom siv busbar uas yuav tsum tau rov kho dua, crimping, lossis brazing, txo qhov kev pheej hmoo ntawm kev ua cov kab nrib pleb. Tsawg-oxygen tooj liab, nrog rau nws tus nqi qis dua, tseem ua tau raws li qhov yuav tsum tau ua feem ntau hauv kev faib hluav taws xob thiab cov kab sib txuas, ua rau nws yog qhov kev xaiv nrov ntsuas kev lag luam thiab kev ntseeg tau.
Dhau li purity, kev ua haujlwm ntawm tooj liab tseem cuam tshuam rau kev ua haujlwm. Mos (annealed) tooj liab busbars muaj siab ductility, yooj yim rau khoov thiab zoo, thiab yog haum rau complex routing thiab nyob rau hauv - site processing; nyuaj (txias- ua haujlwm) tooj liab busbars muaj lub zog ntau dua thiab ua haujlwm rau deformation, ua rau lawv tsim nyog rau kev teeb tsa ruaj khov thiab cov ntawv thov raug rau cov khoom siv tseem ceeb. Kev xaiv cov khoom yuav tsum muaj kev lag luam tawm - tawm ntawm txoj kev teeb tsa, kev ntxhov siab, thiab cov kev xav tau ua tom ntej.
Kev tiv thaiv corrosion yog ib qho tseem ceeb hauv kev xaiv cov khoom. Txawm hais tias tooj liab tsim cov yeeb yaj kiab tiv thaiv oxide nyob rau hauv qhov chaw, qhov kev tiv thaiv corrosion nrawm nyob rau hauv ib puag ncig uas muaj ntsev tsuag, acidic gases, los yog sulfides. Txhawm rau hais txog qhov no, kev tiv thaiv plating lossis txheej txheej tuaj yeem siv rau saum npoo ntawm tooj liab busbars, xws li tin plating, nyiaj plating, lossis txheej nrog cov tshuaj tua kab mob. Tin plating txhim kho solderability thiab qeeb oxidation nto, thaum nyiaj plating txo kev tiv thaiv thiab txhim khu kev tiv thaiv sulfidation nyob rau hauv siab - tam sim no kev sib txuas. Cov coatings tshwj xeeb muab cov teeb meem ntxiv hauv cov cheeb tsam tshuaj lom neeg hnyav.
Rau kev siv tshwj xeeb, tooj liab alloys lossis cov ntaub ntawv sib xyaw kuj raug txiav txim siab. Piv txwv li, ntxiv cov nyiaj ntawm cov nyiaj, cadmium, lossis cov ntsiab lus tsis tshua muaj hauv ntiaj teb tuaj yeem txhim kho siab - kub lub zog thiab nkag siab; composite busbars ua ke nrog cov thermally conductive insulating substrates tuaj yeem ua kom zoo thermal tswj hauv cov ntawv thov nrog cov cua kub tsawg. Txawm li cas los xij, cov ntaub ntawv zoo li no yuav tsum muaj kev ntsuam xyuas dav dav ntawm qhov sib npaug ntawm qhov txo qis conductivity thiab nce nqi.
Feem ntau, kev xaiv ntawm cov khoom siv tooj liab busbar yuav tsum yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob, thaum tseem xav txog kev siv lub zog, kev tiv thaiv corrosion, thiab kev ua kom haum, thiab yuav tsum tau soj ntsuam raws li qhov kev thov ib puag ncig, cov yam ntxwv thauj khoom, thiab kev lag luam. Los ntawm kev xaiv cov khoom siv tshawb fawb thiab kev kho qhov chaw tsim nyog, lub hauv paus kev ua tau zoo tuaj yeem tsim tau rau lub tshuab busbar, kom ntseeg tau ntev - lub sijhawm kev ntseeg siab thiab kev nyab xeeb.
