Cov hlau thaiv cov txheej txheej yog ib qho qauv tsis tseem ceeb hauvNruab nrab-voltage (3.6 / 6kv∽26 / 35kv) Hla Polyethylene-Insulated Power CablesCov. Tsim kom zoo tus qauv ntawm cov hlau thaiv cov hlau, yog suav cov ntaub thaiv npog cov khoom sib txuas lus luv luv ntawm cov cable uas tsim nyog sib xws thiab kev nyab xeeb ntawm tag nrho cov haujlwm tag nrho.
Kev thaiv cov txheej txheem:
Daim thaiv npog hauv nruab nrab-hluav taws xob cable kev tsim tawm yog qhov yooj yim. Txawm li cas los xij, yog tias saib xyuas tsis tau them rau qee cov ntsiab lus, nws tuaj yeem ua rau muaj kev cuam tshuam loj rau cable zoo.
1. Tooj liab XevKev thaiv cov txheej txheem:
Lub tooj liab daim ntaub siv rau kev thaiv kev thaiv yuav tsum yog anealed mos mos tooj liab daim kab xev yam tsis muaj kev tsis xws luag los yog cov kab nrib pleb ntawm ob sab.Tooj liab Xevuas nyuaj dhau lawm tuaj yeem ua rau lubLeevundive Txheej, thaum lub sij hawm xev uas yog muag dhau yuav wrinkle yooj yim. Thaum lub sijhawm qhwv, nws yog qhov tseem ceeb kom teeb tsa lub kaum sab xis, tswj qhov nro kom tsis txhob muaj kev nruj. Thaum cables yog energized, rwb thaiv tsev ua kom muaj cua sov thiab nthuav me ntsis. Yog tias cov tooj liab daim kab xev qhwv kom nruj heev, nws yuav ntim rau hauv cov ntaub thaiv npog lossis ua rau daim kab xev tawg. Cov ntaub ntawv muag muag yuav tsum tau siv rau ntawm cov ntaub qhwv ntsej muag ntawm cov taub hau tshuab ntawm cov ntaub ntawv rov qab los tiv thaiv ib qho kev puas tsuaj rau cov kauj ruam tooj liab thaum cov txheej txheem tom ntej. Yuav tsum muaj cov kab xev liab ua ke yuav tsum yog kev siv tawm,
Tus thawj ntawm tooj liab cov shielding, tiv tauj nrog cov txheej txheem semiconductive yuav ua rau kev sib cuag ntawm lub siab thiab rhuav tshem kev sib cuag los ntawm cov hlau nthuav los yog kev cog lus thiab khoov thiab khoov. Kev sib cuag tsis zoo thiab thermal nthuav kuj yuav ua rau kev puas tsuaj ncaj qha rau sab nraudLeevundive TxheejCov. Kev tiv toj zoo ntawm cov tooj liab daim kab xev thiab cov txheej txheem semiconductive yog qhov tseem ceeb kom ntseeg tau tias tau ua tau zoo. Kev kub dhau los, vim tias los ntawm kev nthuav dav hluav taws xob, yuav ua rau tus tooj liab daim kab xev kom nthuav dav thiab deform, ua kom cov txheej semiconductive txheej. Hauv cov xwm txheej zoo li no, kev tsis zoo welded tooj liab daim kab xev tuaj yeem nqa tau qhov kawg ntawm qhov kawg ntawm qhov chaw semiconductive ntawm taw tes tooj liab lub breakage.
2. Copper hlau tiv thaiv cov txheej txheem:
Thaum ua haujlwm xoob cov tshuab luam ntawv xov tooj liab, cov xaim tooj liab ncaj qha, muaj peev xwm ua kom lub rwb thaiv kom nruj, ua rau muaj kev puas tsuaj cable. Txhawm rau hais txog qhov no, nws yog ib qho tsim nyog los ntxiv 1-2 txheej ntawm cov kab xev nylon ncig lub extruded sicield txheej tom qab extrusion.
Cesles siv xoob lub qhov txhab tooj liab tooj liab hlau thaiv tsis muaj kev txom nyem los ntawm cov kab xev oxide ntawm cov kab xev liab. Tooj liab hlau thaiv muaj tsawg heev khoov, tsawg thermal expusionion deformation, txhua yam uas ua rau muaj kev txhim kho hluav taws xob, tshuab, thiab ua haujlwm thermal hauv kev ua haujlwm cable.
