【Thawj, saib】
1. Paub cov ntawv pov thawj
Thaum yuav khoom, nco ntsoov xyuas seb puas muaj "3C" daim ntawv pov thawj ntawm daim ntawv pov thawj, thiab seb tus qauv specification, qhov ntsuas hluav taws xob, qhov ntev, hnub tsim khoom, tus lej pov thawj, kev tshuaj xyuas, kev siv tus qauv, lub npe Hoobkas, chaw nyob thiab lwm yam cim paub meej.
2. Tshawb xyuas qhov tshwm sim
Thaum yuav khoom, ua tib zoo saib xyuas kom pom tias cov tsos yog du thiab puag ncig, cov xim zoo ib yam, thiab txhais tes zoo li zoo. Yog nws yog roj hmabkab thiab kab, lub plhaub thiab rwb thaiv tsev tuaj yeem hlawv nrog cov luam yeeb pob tw, thiab qhov saum npoo yog tag nrho.
3. Ua tib zoo saib xyuas lub ntim
Thaum yuav khoom, xyuam xim rau cov ntim khoom zoo, luam ntawv ntshiab, ua tiav cov qauv specifications, lub Hoobkas lub npe, chaw nyob, thiab lwm yam. Fake thiab shoddy xov hlau thiab cables feem ntau "peb tsis muaj cov khoom", tab sis lawv kuj muaj cov ntsiab lus tsis meej thiab lwm cov cim ntawm lawv. , xws li ua nyob rau hauv Tuam Tshoj, ua nyob rau hauv ib tug tej lub xeev los yog lub nroog nyob rau hauv Tuam Tshoj, thiab lwm yam, uas yog sib npaug zos rau tsis cim lub hauv paus chiv keeb.
4. Tshawb xyuas qhov ntev
Thaum yuav khoom, tsis txhob npau taws rau tus nqi pheej yig. Thaum yuav cov xov hlau thiab cables nrog tsuas yog 90m lossis 80m, lossis txawm tias tsis muaj qhov cim ntev, qhov ntev yuav tsum ua tau raws li tus qauv xav tau ntawm 100 (ntxiv rau /-) 0.5m.
5. Tshawb xyuas cov tub ntxhais hlau
Diameter - SYV cable yog 0.78-0.8mm, SYWV cable yog 1.0mm; Tsis ntev los no tau muaj SYV75-5 cable nrog ib txoj kab uas hla ntawm 1. xyuas lub cheeb ntawm lub hauv paus ntawm lub cable nrog ib tug vernier caliper.
6. Tshawb xyuas tus neeg xyuas pib
Tus neeg xyuas pib yuav tsum muaj qee yam luster thiab hloov tau yooj yim, thiab qhov tshwm sim loj ntawm tus neeg xyuas pib yuav tsum ua kom tau raws li cov qauv hauv lub tebchaws. Qhov hla ntawm cov tub ntxhais tooj liab ntawm cov xaim thiab cable, thawj-chav kawm tooj liab yog ci xim thiab mos hauv xim, txwv tsis pub nws yog cov khoom tsis raug.
7. Txheeb xyuas cov txheej txheem tiv thaiv
Tus lej puas txaus? Cov tooj liab mesh yog woven los xyuas cov solderability, thiab cov tinned tooj liab computer hlau yog scraped saib seb nws yog tooj liab hlau. Lub hardness ntawm aluminium-magnesium alloy hlau yog pom tseeb ntau dua li ntawm cov hlau hlau; Tsis zoo cable; siv lub teeb ci los hlawv cov tub ntxhais hlau, yog tias nws yog tooj liab-clad aluminium, nws yooj yim pom tias cov xim sab hauv txawv ntawm cov tooj liab sab nraud; tev tawm ntawm daim tawv nqaij thiab pom lub braiding lub kaum sab xis ntawm lub shielding txheej, yog hais tias nws yeej sawv ntsug, ces qhov yooj yim nws yuav pom tau los ntawm saum toj no hais tias lub weaving lub kaum sab xis yog loj, uas yog ib yam khoom uas txiav cov ces kaum.
【Second, test】
Nws yog qhov zoo dua los khoov ib txoj hlua hlau rov qab los ntawm tes. Cov neeg uas muaj lub ntsej muag muag muag, kev qaug zog zoo, yas lossis roj hmab xav tias elastic thiab tsis muaj kab nrib pleb ntawm cov hlau insulator yog cov khoom zoo tshaj.
1. Sim toughness
Tsim nyog tooj liab tub ntxhais hlau tooj liab tub ntxhais yuav tsum yog ntshav, ci iab thiab mos rau qhov kov. Cov tub ntxhais tooj liab ntawm cov khoom cuav thiab tsis zoo tooj liab tub ntxhais hlau yog xim liab-dub, daj lossis dawb, nrog ntau yam impurities, tsis muaj zog txhua yam thiab tsis zoo toughness. Thaum kuaj xyuas, koj tsuas yog yuav tsum tau tev tawm ib qho kawg ntawm cov hlau los ntawm 2cm, thiab tom qab ntawd rub ib daim ntawv dawb ntawm cov tub ntxhais tooj liab. Yog tias muaj cov khoom siv dub rau ntawm daim ntawv dawb, nws txhais tau tias muaj cov impurities ntau dua hauv cov tub ntxhais tooj liab.
2. Longitudinal tensile zog
Siv ib lub 'meter' ntawm kev ruaj ntseg cable, tev tawm cov tub ntxhais hlau, txheej rwb thaiv tsev, tiv thaiv txheej, thiab lub tsho sab nrauv hauv cov khaubncaws sab nraud povtseg, tawm 10 cm ntev rau txhua tus. Cov txheej txheem yog: tuav ob txheej ntawm cov kab uas nyob ib sab nrog ob txhais tes thiab rub lawv nyob rau hauv cov lus qhia rov qab; Cov kab hluav taws xob zoo tsis tuaj yeem rub nrog lub zog dav dav, thiab cov cables tsis zoo tuaj yeem rub tawm yooj yim yam tsis muaj kev siv zog ntau.
3. Pinch lub PVC sheath
Nyob rau saum npoo, nws tuaj yeem pom tias tsis tu ncua "tsis sib xws" ntawm cov mesh hauv compression, qhia tias kev siv tshuab ua haujlwm zoo, yuav tsis muaj qhov sib txheeb zawv zawg, thiab nws yog ib qho zoo cable. Cov tsos yog du, thiab "unevenness" ntawm compressed braided net tsis tuaj yeem pom. Muaj kev xav xoob thaum pinching lub sheath ntawm tes, uas yog ib qho tsis zoo cable;
4. Sim xyuas qhov adhesion ntawm cov tub ntxhais hlau thiab cov txheej insulating
Txiav cov txheej insulating diagonally, rub cov tub ntxhais hlau nyob rau hauv cov kev taw qhia tev, thiab xyuas seb cov tub ntxhais hlau thiab cov txheej insulating puas yog adhered rau cov txheej txheem khoom; qhov zoo cable muaj ib tug loj adhesion quab yuam, thiab cov neeg pluag cable tsis adhere.
5. Qhov hnyav
Qhib lub kauj ntawm cov hlau los ntsuas qhov ntev, lossis siv txoj kev hnyav los txiav txim siab tias cov xov hlau zoo feem ntau nyob rau hauv qhov ntsuas qhov hnyav. Piv txwv li, feem ntau siv cov yas insulated ib leeg-strand tooj liab tub ntxhais hlau nrog ib tug ntoo khaub lig-sectional cheeb tsam ntawm 1.5mm2 muaj ib tug luj ntawm 1.8 mus rau 1.9kg ib 100m; ib tug yas insulated ib leeg-strand tooj liab tub ntxhais hlau ntawm 2.5mm2 muaj ib tug luj ntawm 3 mus rau 3.1kg ib 100m; yas ntawm 4.0mm2 Insulated ib leeg-strand tooj liab tub ntxhais hlau, qhov hnyav ntawm 100m yog 4.4 ~ 4.6kg, thiab lwm yam. Cov hlau tsis zoo yog qhov hnyav, tsis ntev txaus, los yog muaj impurities ntau dhau ntawm cov tub ntxhais tooj liab ntawm cov hlau.
【thib ob, kev sib piv】
Vim tias cov khoom siv hluav taws xob tsis zoo thiab cov khoom siv hluav taws xob tsis zoo, cov tub lag luam feem ntau muag lawv ntawm tus nqi qis raws li cov khoom siv hluav taws xob pheej yig thiab cov khoom siv hluav taws xob zoo, uas ua rau tib neeg dag.
