Thaum lub caij ntuj no, huab cua txias. Thaum txhim kho cov xov hlau thiab cables, koj yuav pom tias cov xov hlau thiab cov cables ntawm cov khoom zoo feem ntau muaj qee qhov tshwm sim xws li hardening ntawm lub cev hlau thiab ntog tawm ntawm cov insulating sheath. Ntau tus neeg yuav khoom xav tias nws yog cov khoom siv hlau thiab cable lawv tus kheej. Txawm li cas los xij, cov tuam txhab cable kuj tseem hais tias cov khoom tau raug tshuaj xyuas ua ntej tawm hauv lub Hoobkas thiab yog cov khoom tsim nyog, uas feem ntau ua rau muaj kev nkag siab tsis zoo ntawm ob tog.
Qhov tseeb, nws tsis yog qhov zoo ntawm cov khoom nws tus kheej yog qhov tsis ncaj ncees lawm, tab sis vim yog qhov txias txias hauv lub caij ntuj no. Cov tawv nqaij sab nrauv ntawm cov khoom siv hlau thiab cable yog feem ntau cov yas zoo tib yam (PVC) lossis roj hmab. Thaum lawv nyob rau hauv ib cheeb tsam sub-zero, lawv yuav nyuaj, thiab tag nrho cov xaim thiab cable khoom kab yuav nyuaj thiab nkig, uas ua rau cov tawv nqaij sab nrauv yuav nyob rau hauv qhov kev txiav txim ntawm me ntsis sab nraud quab yuam. poob los yog puas. Nyob rau lub caij ntuj no, tshwj xeeb tshaj yog nyob rau sab qaum teb, qhov kub ntawm sab nraum zoov feem ntau qis dua xoom, thiab qhov kub ntawm qhov chaw yuav qis dua. Yog li ntawd, yog tias cov khoom siv hlau thiab cable raug muab tso rau sab nraum zoov lossis ncaj qha rau hauv av, cov tawv nqaij sab nrauv ntawm cov khoom yuav poob tawm. Tom qab ntawd, txhawm rau tiv thaiv qhov xwm txheej saum toj no, cov kev ntsuas hauv qab no tuaj yeem ua:
1. Kev xa khoom los ntawm lub Hoobkas: Thaum cov khoom thauj khoom ntawm lub tsheb thauj mus los, nws yuav tsum tau ua kom sov thiab tiv thaiv kev ntsuas. Piv txwv li, siv lub tshuab thauj khoom kaw los tiv thaiv cov khoom los ntawm kev raug ncaj qha; cushion cov khoom nrog cov khoom softer; tuav nws nrog kev saib xyuas thaum thauj khoom, tsis txhob thauj cov khoom hnyav, thiab tsis txhob khoov ntau dhau ntawm cov khoom.
2. Thaum tuaj txog ntawm qhov chaw lossis qhov chaw tsim khoom, tus neeg muag khoom yuav tsum xa cov neeg ua haujlwm los saib xyuas kom tsis txhob muaj kev ua haujlwm tsis zoo thaum cov khoom tsis thauj khoom.
3. Cia: Nws yog qhov zoo tshaj plaws los khaws cov khoom hauv tsev, thiab tib lub sijhawm, nteg ib txheej txheej ntawm kev sib cais ntawm qhov chaw cia, xws li ntoo, txaj, ua npuas ncauj, thiab lwm yam., kom tiv thaiv cov khoom los ntawm khov thiab ntub dej. , thiab xyuam xim tiv thaiv cov khoom los ntawm kev sib cuag nrog hauv av. Yog hais tias lub cable sheath yog khawb, ua tib zoo saib xyuas.
4. Thaum cov khoom tso thiab ntsia: nws yog qhov zoo tshaj plaws los xaiv ua haujlwm nyob rau hauv cov ntaub ntawv ntawm sov sov nyob rau hauv lub yav tav su thiab yav tav su, thiab nruab nws nyob rau hauv lub xeev ntawm cov khoom zoo. Yog hais tias nws yog faus rau hauv av, ib txheej tiv thaiv, xws li daim ntaub thiab ua npuas ncauj, tuaj yeem muab tso rau hauv lub cable trench ua ntej. Yog tias nws yog cov yeeb nkab, xyuas kom cov yeeb nkab sab hauv thiab sab nraud yog du kom cov hlau tsis muaj khawb. Tshwj xeeb yuav tsum tau them nyiaj rau cov kav hlau. Thaum yuav cov kav hlau hlau zoo, tej zaum yuav muaj ntau tus ntse protrusions nyob rau hauv cov kav hlau uas tsis zoo, uas muaj feem ntau yuav khawb cov tawv nqaij ntawm cov xov hlau.
5. Xaiv cov kab hluav taws xob qis thiab ntsuas lawv nruj raws li cov kev cai xeem ntawm lub teb chaws tus qauv "GB/T2951.14-2008", muab tso rau hauv ib puag ncig ntawm rho tawm 35 degree rau 16 teev, thiab tom qab ntawd nqa tawm mechanical performance tests. Thiab lub tsho yog kuaj rau elongation thiab tensile lub zog, thiab tus nqi dhau yog 100 feem pua.
