90% ntawm cov chaw nres tsheb thauj khoom tau tsoo rau hauv plaub kab loj loj loj}}} thiab ncaj ncees, nws yog zam kev ntxhov siab! Cia kuv qhia koj ib zaj dab neeg zoo nkauj ua ntej: Txoj cai thaum tooj liab tus nqi, ib cheeb tsam tooj liab chaw xaiv tsa tooj liab cable txo tus nqi. Tsawg dua li ib xyoos tom qab, cov cables hloov mus rau hauv lub zog hluav taws xob machine, thiab cov nqi kho tau xaus ua peb zaug lawv tau txais kev cawmdim thaum pib. Tu siab? Kiag li. Tab sis qhov xwm txheej tiag tiag yog ua si ntawm cov chaw them nyiaj hauv lub tebchaws.
Qhov khoom yog, them nyiaj haum ncaj qha rau kev nyab xeeb lub neej {{} Yog li cia li ua cov ntxiab koj tau nkag mus rau hauv?
Lately, qhov tsis muaj hlau hlau ua lag luam tau tag nrho cov menyuam mos. Hnov tus nqi tooj liab poob qis dua 85,000 Yuan ib tuj, thaum lub sij hawmÂinate ntsiag to crept los ntawm 10 yuan. AMID TXHUA TUS NQI TONE, Tuam Tshoj Lub Tsheb Them Tsheb Cable lag luam tau ntaus ntau tshaj li 12,8 billion yuan, loj hlob 23.6%. Tab sis ntawm no yog qhov txaus ntshai: ntau dua 30% ntawm cov cables ntawm kev ua lag luam yog Shoddy, tsis {{tus qauv khib nyiab! Raws li ib tug neeg los ntawm Zhejiang Zhongjing cable, Kuv nyob ntawm no mus rau kev lag luam kev lag luam qias neeg tsis txaus ntseeg "kev tsim txom" yog kev ua phem ua yuam kev.
Pitfall 1: Kev Nkag Siab Cable Cov Khoom Siv (qhov mob tshaj plaws!)
Cia tso qhov tseeb hnyav: Ntau tus neeg yuav khoom tau dazzled los ntawm cov lus tsis tshua muaj thiab tsis tuaj yeem qhia qhov sib txawv ntawm rov ua dua tooj liab thiab oxy {tooj dawb. Xyoo tas los, ib lub chaw nyob ze dav dav dav dav dav chaw nres tsheb bragged txog kev txuag tooj los yog kev siv cov khoom siv rov qab los nrog kev kub ntxhov rau txhua lub lim tiam. Frankly, txhua tus neeg uas hu ua kev lom zem ntawd yuav tsum tau muaj lub zog tam sim ntawd nruab nrab {}}}} kev them lawv tus kheej!
Cia peb tau txais kev tshawb fawb (tab sis tsis dhuav): oxygen - nws cov pa dawb muaj nyob rau hauv 0.017. Rov ua dua tus tooj liab, txawm yog? Nws yog kev sib xyaw ua ke ntawm cov khib nyiab, thauj khoom nrog impurities, thiab nws tiv taus feem ntau spikes los ntawm 50%. Thiab tsis txhob txawm tias tau pib ntawm tooj liab {{}} clad aluminium "tshuaj pleev ib ce"- lawv kev coj ua yog txiav hauv ib nrab! Qhov no tsis yog txiav cov ces kaum; Nws yog tsim lub sijhawm zuam lub sijhawm hauv xaim daim ntawv.
Tus Pitfall 2: Tus ntoo khaub lig-}} seem loj ntxiab (tuab tsis yog txhua yam!)
Tsis txhob xav tias txhua tus xaim ntawm tib tuab yog sib npaug ntawm ib qho, thiab koj yuav tuaj yeem ntawm qhov hluav taws xob nrawm dua li koj tuaj yeem hais tau "ceev ceev." Lub siab - Kev pabcuam ceev kev pabcuam hauv cheeb tsam yog classic: lawv tau nruab ib lub 120kw ceev {{4 4 4} Tus them se mus rau 50 hli clesnes. Zoo li zoo, txoj cai? Tab sis ntawm 80 meters deb, kab poob txhaj tshuaj li 8%, thiab tus nqi them nyiaj pib ua yeeb yam zoo li nws tau qaug dab peg, tsis muaj kev ntseeg tau, tsis muaj qab hau.
Pitfall 3: Tus Txheej Txheem Tiv Thaiv Myth (ib qho loj me tsis haum rau txhua tus!)
Qee pab pawg tsim kho tau tawm ntawm no ua qhov tsis muaj tseeb tshaj plaws: lawv yuav siv cov chaw nres tsheb sab nraum zoov (qhov chaw nkaum!) Tab sis npuaj dab tsi dog dig show piles. Nws yog txaus luag - kom txog thaum nws tsis yog. Hauv cov cheeb tsam uas muaj cov duab hluav taws xob UV muaj zog, cov khoom siv hluav taws xob zoo tib yam tig mus rau hauv brittle spaghetti hauv rau lub hlis. UPRY North, qhov nws tau khov, cov rwb thaiv tsev txheej tau txais li qos yaj ywm chips thiab tawg ntawm me ntsis khoov.
Ib qho kev daws teeb meem tiag tiag yuav tsum tau ua kom ib puag ncig: rau qhov siab {{} Kev Tiv Thaiv Plab, mus rau IP68 2}} qib seafarine; Cov cheeb tsam cua thiab xuab zeb yuav tsum muaj cov cabored cables kom tsis txhob tawg; Tshuaj lom neeg cov chaw ua si yuav tsum tau corrosion - cov ntaub ntawv resistant. Cov hnub no, qee cov cable tshiab txawm tau tsim-}}}} kub {} {} {} txhua yam tsis tseem ceeb.
Pitfall 4: Kev teeb tsa Seneranigans (txiav cov ces kaum= kev puas tsuaj!)
Kuv tau pom pab pawg tsim kho kom khoov rau hauv "cov nab uas khav theeb" thiab hais, "nws txuag tau chaw." Spoiler: Nws txuag chaw kom txog thaum lub cable tuag. Lub khw khw lub chaw them nyiaj tau ua qhov no- vim hais tias qhov kev ntaus nqi sab hauv, thiab thaum kawg, tag nrho cov kev sib kis tau zoo.
Here's the rulebook (and these aren't just suggestions-they're blood, sweat, and repair bill lessons): non-armored cables need a bending radius of at least six times their outer diameter! Ntsug muab kev sib txuas yuav tsum yog ua kom muaj zog txhua 'meter' meter! Crimping Terminals yuav tsum tau ntsib lub teb chaws tus qauv GB / T 14315! Cov xov tooj no tsis yog rau qhia -} Lawv muaj kev tiv thaiv kev puas tsuaj. Ntse siab -} Cov chaw nres tsheb kawg twb siv thermal kev kuaj mob rau peb hlis. Siv nyiaj ntawm no; Nws yog txoj kev pheej yig dua tom qab - {8} {qhov tseeb kho.
Cov kab hauv qab: nws yog txhua yam txog kev nyab xeeb thiab kev coj ua
Xaiv lub cable tsis yog hais txog tus nqi - nws yog kev sim ntawm kev nyab xeeb thiab kev coj ua lag luam. Thaum tus nqi tooj liab yog viav vias zoo li vwm, peb yuav tsum tau ceev faj ntxiv rau cov "nqi - cov ntxiab. Cia peb ua tiag tiag: lub cable zoo yuav tsum zoo li tus tub qhe laus loyal, ntsiag to saib thoob txhua qhov kev them nyiaj. Thaum nws los txog rau kev nyab xeeb, peb tsis yog kev twv txiaj nrog nyiaj - Peb twv txiaj nrog kev zoo siab ntawm tsev neeg suav tsis tau. Thiab qhov ntawd yog qhov chaw twv tsis muaj leej twg yuav tsum tau plam.
