Txhim Kho Nws Txoj Kev Hloov Hluav Taws Xob thiab Kev Sib Txuas Zoo
May 08, 2018

Kev siv fiber ntau ntawm fiber ntau yog kab kev sib txuas lus uas muaj ob los sis ntau tshaj iav los yog ntau lub khob fiber ntau uas muaj nyob rau hauv ib qho kev tiv thaiv thiab muaj kev tiv thaiv los ntawm PVC yas tsho yas. Cov teeb meem kev sib tshuam nrog cov fibers hauv kev siv feem ntau siv cov teeb ci teeb ci.

1. Keeb kwm kev xyaum ua pov thawj;

Aluminium alloy cable tau raug tsim thiab siv hauv Tebchaws Meskas txij xyoo 1968. Nws tau siv rau 43 xyoos. Kev siv cov khoom no tau dhau los. Lub lag luam tawm ntawm North American lub teb chaws tau mus txog 80%. Tom qab 43 xyoo ntawm kev xyaum, nws tau raug pov thawj tias kev siv cov aluminium alloy cables yeej tsis ua tsis tau thiab muaj kev ruaj ntseg.

2, kev sim thiab kev lees paub;

Aluminium alloy cables kis UL los ntawm Tebchaws Asmeskas, CUL ntawm Canada, SAIGLOBAI los ntawm Australia, thiab Tuam Tshoj lub teb chaws xov tooj thiab xov chaw, Lub Nroog Grid Wuhan High Voltage Research Institute, National Fireproof Tsev Khoom Saib Xyuas Kev Tshawb Nrhiav thiab Kev Tshawb Fawb Xyuas thiab lwm cov koom haum. Cov neeg tsav tsheb sib tw ua tau raws li kev cai ntawm CSA Standard C22.2 Tshooj 38 hais txog ACM cov hlau xov tooj, thiab kev ua haujlwm ntawm cov kev hloov tshiab ntawm GB12706.1- 2008 thiab IEC60502.1, thiab cov qauv ntawm UL cov kev cai AA8000 Series.

3, lub luag haujlwm ntawm txhuas cov npuas txhuas;

◆ Aluminium alloy conductor Ntxiv cov tsis tshua muaj lub ntiaj teb thiab hlau thiab lwm yam khoom loj heev ua kom nws cov khoom siv thiab kev sib txuas ua ke. Tshwj xeeb tshaj yog thaum tus neeg xyuas pib annealed, qhov sib ntxiv ntawm cov hlau ua ib lub zog ua siab tawv. Thaum qhov tam sim no yog overloaded, cov hlau tseem ua haujlwm. Lub luag hauj lwm ntawm kev twb kev txuas, yog li ntawd cov txhuas hlau txhuas hlau yuav tsis creep.

◆ Tsim ua kom lub xov tooj poob. Yog hais tias lub cable yog creeping, thawj lub siab ntawm qhov chaw sib tiv tauj tsis nruj txaus, thiab kev tiv thaiv kuj yog nce ntau zog vim lub siab txo. Tom qab cov dej ntws tam sim no, tus connector tseem ceeb dua. Yog tias lub xov tooj tsis tuaj yeem kho tsis tu ncua, nws yuav pom kev nyab xeeb. Kev nyab xeeb ntawm kev nyab xeeb. Nws tseem ceeb heev kom daws tau qhov teeb meem ntawm cable creep.

Creep: Nyob hauv kev kub, kev quab yuam sab nraud thiab nws qhov nyhav, cov hlau yuav maj mam tsim ua kom deformation uas tsis tuaj yeem txum tim lub sijhawm dhau los. Qhov no phenomenon yog creep.

4, nplaim hluav taws

Cov rwb thaiv tsev ntawm txhuas hlau siv hluav taws xob siv hluav taws xob tua kab hluav taws xob polyethylene (XLPE). Tus txheej txheem tsim kho tus qauv xauv npab nws tus kheej. Kev kub txheej txheem cua kub yog qhov zoo dua li cov khoom siv PVC. Nws tau dissipate heat sai thiab nplaim taws sai sai tom qab nplaim taws. , yuav tsis ncua lwm yam ntaub ntawv, nplaim nplaum zoo dua qub. Aluminium alloy cables siv cov ntaub ntawv tshiab thiab cov txheej txheem tshiab los xyuas meej kom lawv siv kev nyab xeeb.
