Kev tshuaj xyuas zoo ntawm cov hlau-cored aluminium stranded hlau npog ntau qhov ntev, suav nrog qhov ntev ntawm cov qauv, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab qhov chaw thiab plating zoo, ua kom muaj kev ua haujlwm txaus, lub zog tensile, thiab kav ntev hauv cov kab sib kis.
Hom kev tshuaj xyuas no yog ua nyob rau hauv tag nrho cov txheej txheem ntawm kev tsim cov neeg xyuas pib, kev lees txais kev sib txuas ntawm daim phiaj, thiab hauv - kev saib xyuas kev pabcuam, thiab yog qhov txuas tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ruaj khov ntawm daim phiaj hluav taws xob. Kev tshuaj xyuas yog feem ntau raws li cov qauv hauv tebchaws xws li GB / T 1179-2017 "Round Wire Concentric Stranded Overhead Conductors" thiab GB / T 3428, ua ke nrog cov qauv kev lag luam DL / T 371 series.
Cov khoom tseem ceeb ntawm kev tshuaj xyuas yog raws li nram no:
Kev soj ntsuam ntawm tus qauv Dimension
Ntsuas cov kab sab nraud ntawm cov hlua khi, txoj kab uas hla ntawm cov txhuas ib leeg xaim thiab cov tub ntxhais hlau, lub suab piv, cov xov tooj ntawm cov hlua, thiab lawv cov kev taw qhia (feem ntau yog txheej txheej sab nraud yog txoj cai - tes Z - kev taw qhia).
Siv micrometers, calipers, lossis multi-point diam gauges kom ntseeg tau tias ua raws li cov qauv tsim.
Mechanical Performance Testing
Resolution Tensile Strength (RTS) Test: Ua rau ntawm lub tshuab ntsuas universal. Qhov ntsuas tus nqi yuav tsum tsis pub tsawg dua 95% ntawm tus nqi nominal, thiab kev poob lossis kev puas tsuaj kawg yuav tsum tsis txhob tshwm sim ua ntej tawg.
Kev ntxhov siab-Cov yam ntxwv zoo thiab Elastic Modulus: Deformation tus cwj pwm thaum lub sij hawm thauj khoom raug kaw siv lub extensometer rau sag xam thiab nro tsim.
Kev Ntsuam Xyuas Kev Nyuaj Siab ntawm 1% Elongation: Ntsuam xyuas tus neeg xyuas pib lub peev xwm deformation nyob rau hauv ntev - lub sij hawm ua hauj lwm loads thiab yog ib tug tseem ceeb qhia ntawm nws mechanical stability.
Kev qaug zog thiab kev ua haujlwm siab: Simulates dynamic loads xws li cua vibration thiab dej khov loads los xyuas kom meej tus neeg xyuas pib qhov kev cia siab ntawm lub sij hawm ntev - kev pab cuam.
Kev Ntsuas Hluav Taws Xob
DC Resistance Measurement: Ntsuas siv plaub -terminal micro-ohmmeter nyob rau hauv isothermal tej yam kev mob. Siv los xam cov conductivity lossis resistivity thiab txiav txim siab kis tau tus mob.
High conductivity conductors kuj yuav tsum tau AC tsis kam, tam sim no nqa peev xwm pov thawj, thiab corona pib voltage kuaj.
Txheej thiab Corrosion Resistance Test
Zinc Coating Adhesion (Wrapping Test): Tightly qhwv cov hlau xaim nyob ib ncig ntawm ib puag ncig puag ncig rau 8 lem, tom qab ntawd tshem tawm thiab rov qab, xyuas kom tawg lossis tev.
Zinc Txheej Qhov Ntsuas Qhov Ntsuas: Siv cov txheej txheem tooj liab sulfate etching los yog txoj kev hnyav kom ua raws li cov kev cai tiv thaiv corrosion.
Cov xov hlau rau ib puag ncig tshwj xeeb kuj xav tau kev sim ua kom muaj zog xws li ntsev tsuag corrosion thiab kev ntxhov siab corrosion rhiab heev.
Surface Quality thiab Process Inspection
Saib xyuas qhov chaw ntawm aluminium hlau thiab steel core kom smoothness, tawg, burrs, oxidation, roj stains, los yog roj ntau dhau.
Stretching yuav tsum zoo ib yam thiab nruj, tsis muaj xoob strands los yog misalignment. Qhov sib txuas sib txuas yuav tsum siab dua 15mm thiab zoo sib xws.
Lwm Cov Kev Xeem Tshwj Xeeb
Winding Test: Txheeb xyuas qhov toughness ntawm ib lub xaim nyob rau hauv rov qab khoov kom tsis txhob tawg vim yog khoov thaum lub sij hawm tsim kho.
Kev tshuaj xyuas zoo crimping: Qhov ntev, tuav lub zog, tiv thaiv kev tiv thaiv, thiab qhov tsis xws luag sab hauv (xws li porosity thiab tsis muaj compression) ntawm crimped qhov chaw ntawm cov khoom sib txuas tau raug tshuaj xyuas.
