1, Txheeb xyuas cov ntawv pov thawj.Cov khoom uas tau txais daim ntawv pov thawj yuav tsum tau muab tso rau hauv daim ntawv pov thawj, uas yog lub cim "CCC", nyob rau hauv ib txoj hauj lwm tseem ceeb ntawm cov khoom, txwv tsis pub lawv yog cov khoom tsis muaj ntawv tso cai.
2, Saib ntawm daim ntawv tshuaj ntsuam xyuas.Raws li cov khoom uas cuam tshuam txog kev nyab xeeb ntawm tus kheej thiab khoom ntiag tug, hlau thiab cable yeej ib txwm tau teev tseg raws li qhov tseem ceeb ntawm tsoomfwv saib xyuas thiab tshuaj xyuas. Cov tuam txhab lag luam tsis tu ncua raug tshuaj xyuas los ntawm cov chaw saib xyuas tsis tu ncua.Yog li ntawd, cov neeg muag khoom yuav tsum muaj peev xwm muab cov ntaub ntawv soj ntsuam los ntawm cov chaw soj ntsuam zoo, txwv tsis pub muaj qhov tsis muaj lub hauv paus rau kev txiav txim siab qhov zoo ntawm cov khoom.
3, Rwb thaiv tsev thiab sheath testing.Lub thickness ntawm rwb thaiv tsev thiab sheath yuav tsum zoo ib yam thiab tsis muaj deflection, thiab yuav tsum tau pom tseeb nro thiab elongation ntawm tes kov.Tam sim no, lub nto ntawm rwb thaiv tsev thiab sheath yuav tsum muaj nruam luam ntawv cim. ntawm cov chaw tsim khoom npe thiab cov qauv khoom, nrog rau qhov sib txawv ntawm qhov tsis muaj ntau tshaj 200mm rau rwb thaiv tsev thiab tsis pub tshaj 500mm rau sheath.
4, Saib xyuas qhov smoothness thiab xim ntawm lub cev hlau.Tus neeg xyuas pib ntawm cov hlau thiab cable yog cov hlau-plated los yog tsis-hlau-plated annealed tooj liab hlau, thiab aluminium conductor yog aluminium lossis aluminium alloy hlau nrog ib tug du nto. Tus neeg xyuas pib tooj liab yog lub teeb liab thiab lub txhuas tus neeg xyuas pib yog nyiaj dawb. Txwv tsis pub, tus neeg xyuas pib yuav raug tov nrog lwm yam impurities, ua rau txo qis hauv conductivity.
5, Ntsuas DC tsis kam.Txhim kho qhov zoo ntawm cov xaim xaim thiab cable, nws raug nquahu kom ua ntej txiav 3-5 meters ntawm cov khoom yuav tsum tau yuav thiab xa mus rau lub chaw soj ntsuam rau DC kev ntsuas.
6, Ntsuas qhov ntev.National cov qauv muaj cov kev cai meej ntawm kev xa khoom ntev ntawm cov xaim thiab cable.Qhov ntev ntawm lub kauj yuav tsum yog 100m, thiab qhov ntev ntawm lub reel yuav tsum siab tshaj 100m. Cov neeg siv khoom tuaj yeem ntsuas raws li qhov ntev ntawm daim ntawv lo. Tus qauv qhia tias qhov kev ua yuam kev ntev yuav tsum tsis pub tshaj 0.5% ntawm tag nrho qhov ntev.Yog tias nws tsis ua raws li qhov kev txwv qis ntawm tus qauv, nws raug suav tias yog qhov tsis tsim nyog.
