1. Dab tsi yog waterproof cable?
Cables uas yuav siv tau ib txwm nyob rau hauv dej yog collectively hu ua dej-resistant (waterproof) fais fab cables. Thaum lub cable tso rau hauv qab dej, feem ntau muab tso rau hauv dej los yog qhov chaw ntub dej, lub cable yuav tsum muaj kev ua haujlwm ntawm kev tiv thaiv dej (ua haujlwm), uas yog, nws yuav tsum muaj kev ua haujlwm ntawm cov dej tsis kam, txhawm rau tiv thaiv dej los ntawm kev nkag mus rau hauv lub cable, ua rau kev puas tsuaj rau cable, thiab ua kom lub zog ruaj khov ntawm cov dej hauv qab dej. Cov qauv siv hluav taws xob tsis zoo yog JHS, uas belongs rau roj hmab tes tsho waterproof cable, waterproof cable kuj muab faib ua waterproof fais fab cable thiab waterproof computer cable, thiab lwm yam., thiab cov qauv neeg sawv cev yog FS-YJY, FS-DJYP3VP3.
2. Hom qauv tsis muaj dej tsis zoo
(1). Rau ib leeg-core cables, qhwv lubsemi-conductive dej thaiv daim kab xevntawm cov ntaub thaiv npog rwb thaiv tsev, qhwv qhov dog digdej thaiv daim kab xevsab nraud, thiab tom qab ntawd nyem lub plhaub sab nrauv, txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm Cov ntaub ntawv hauv ob sab hauv thiab sab nraud yog tib yam li cov tau piav qhia hauv cov tub ntxhais ib leeg.
(2). Ib txheej yas coated aluminium daim kab xev yog longitudinally qhwv rau hauv lub txheej sheath los yog puab txheej txheej raws li ib tug waterproof txheej.
(3). Extrude HDPE sab nrauv sheath ncaj qha rau ntawm cable. Lub XLPE insulated cable saum toj no 110kV yog nruab nrog cov hlau sheath kom ua tau raws li qhov yuav tsum tau muaj dej tsis zoo. Cov ntaub thaiv npog hlau muaj tag nrho impenetrability thiab zoo radial dej tsis kam. Lub ntsiab ntawm cov hlau sheath yog: kub pressed aluminium lub tes tsho, kub pressed lead tes tsho, welded corrugated txhuas lub tes tsho, welded corrugated steel tes tsho, txias drawn hlau tes tsho thiab hais txog.
3. Waterproof daim ntawv ntawm waterproof cable
Feem ntau muab faib ua Vertical thiab radial dej tsis kam ob. Vertical dej tsis kam yog feem ntau siv raudej thaiv cov xov paj, dej hmoov thiab dej thaiv daim kab xev, dej tiv thaiv mechanism yog nyob rau hauv cov ntaub ntawv no muaj ib tug dej yuav nthuav cov khoom, thaum cov dej los ntawm lub cable kawg los yog los ntawm lub sheath defect mus rau hauv, cov ntaub ntawv no yuav nthuav dej sai heev los tiv thaiv ntxiv diffusion raws cable longitudinal, kom ua tiav lub hom phiaj ntawm cable longitudinal waterproof. Lub radial dej tsis kam yog ua tiav los ntawm extruding HDPE non-metallic sheath los yog kub nias, vuam thiab txias kos hlau sheath.
4. Kev faib tawm ntawm cov cables tsis muaj dej
Muaj peb hom kab hluav taws xob tsis zoo siv hauv Suav teb:
(1). Roj-daim ntawv insulated cable yog cov feem ntau raug dej resistant cable. Nws cov rwb thaiv tsev thiab cov khoom siv hluav taws xob tau ntim nrog cov roj cable, thiab muaj lub tsho hlau (lub tsho txhuas lossis lub tsho txhuas) sab nraum lub rwb thaiv tsev, uas yog qhov zoo tshaj plaws dej tsis kam cable. Nyob rau hauv lub dhau los, ntau submarine (los yog underwater) cables siv roj-daim ntawv insulated cables, tab sis roj-daim ntawv insulated cables raug txwv los ntawm qhov poob, muaj teeb meem ntawm cov roj to, thiab kev kho yog tsis yooj yim, thiab tam sim no lawv siv tsawg thiab tsawg.
(2). ethylene propylene roj hmab insulated cable dav siv nyob rau hauv qis thiab nruab nrab voltage underwater kis kab yog vim nws superior rwb thaiv tsev kev ua tau zoo yam tsis muaj kev txhawj xeeb ntawm "dej tsob ntoo". Waterproof roj hmab sheathed cable (Hom JHS) tuaj yeem ua haujlwm nyab xeeb hauv dej ntiav ntev ntev.
(3). Hla-txuas polyethylene (XLPE) insulated fais fab cable vim nws cov khoom siv hluav taws xob zoo heev, txhua yam thiab lub cev, thiab cov txheej txheem tsim khoom yog yooj yim, lub teeb qauv, muaj peev xwm kis tau tus mob loj, kev teeb tsa thiab kev saib xyuas yog yooj yim, tsis txwv los ntawm kev poob thiab lwm yam zoo, ua cov khoom siv rwb thaiv tsev feem ntau, tab sis nws yog tshwj xeeb tshaj yog rhiab rau ya raws, hauv kev tsim thiab kev ua haujlwm yog tias cov rwb thaiv tsev muaj dej "lub neej luv luv" kev pab cuam lub neej. kab. Yog li ntawd, tus ntoo khaub lig-txuas polyethylene insulated cable, tshwj xeeb tshaj yog nyob rau hauv nruab nrab thiab high voltage cable nyob rau hauv qhov kev txiav txim ntawm AC voltage, yuav tsum muaj ib tug "dej thaiv cov qauv" thaum siv nyob rau hauv ib puag ncig dej los yog ib puag ncig ntub.
5. Qhov sib txawv ntawm cov khoom siv dej tsis zoo thiab cov kab hluav taws xob zoo tib yam
Qhov sib txawv ntawm cov cables tsis muaj dej thiab cov kab hluav taws xob zoo tib yam yog cov kab hluav taws xob zoo tib yam siv tsis tau hauv dej. JHS waterproof cable kuj yog ib hom roj hmab sheath saj zawg zog cable, lub rwb thaiv tsev yog roj hmab rwb thaiv tsev, thiab zoo tib yam roj hmab sheath cable, JHS waterproof cable yog feem ntau siv, tab sis nws yog nyob rau hauv dej los yog ib co yuav dhau los ntawm cov dej. Waterproof cables feem ntau yog 3 cores, feem ntau yog siv thaum txuas lub twj tso kua mis, tus nqi ntawm waterproof cables yuav kim dua li cov roj hmab sheath cables, nws yog ib qho nyuaj rau paub qhov txawv ntawm waterproof los ntawm cov tsos, koj yuav tsum sab laj tus neeg muag khoom kom paub cov waterproof txheej.
6. Qhov sib txawv ntawm cov kab dej tsis zoo thiab cov kab dej tsis zoo
Waterproof cable: tiv thaiv dej los ntawm kev nkag mus rau sab hauv ntawm cov qauv cable, siv cov qauv dej tsis zoo thiab cov khoom siv.
Dej thaiv cov kab hluav taws xob: Qhov kev ntsuam xyuas tso cai rau dej nkag mus rau sab hauv ntawm lub cable, thiab tsis tso cai nkag mus rau qhov ntev raws li qhov xwm txheej. Water blocking cable muab faib ua tus neeg xyuas pib dej thaiv thiab cable tub ntxhais dej thaiv.
Dej thaiv cov qauv ntawm tus neeg xyuas pib: ntxiv dej thaiv cov hmoov thiab dej thaiv cov xov paj hauv cov txheej txheem ntawm ib txoj hlua khi, thaum tus neeg xyuas pib nkag mus rau hauv dej, cov dej thaiv cov hmoov los yog cov dej thaiv cov xov paj nthuav tawm nrog dej kom tsis txhob nkag mus rau hauv dej, ntawm chav kawm, tus neeg xyuas pib muaj cov dej thaiv zoo dua.
Dej thaiv cov qauv ntawm cov tub ntxhais cable: thaum lub plhaub sab nrauv puas thiab cov dej nkag mus, cov dej thaiv kab xev nthuav dav. Thaum cov dej thaiv daim kab xev nthuav dav, nws sai sai tsim cov dej thaiv cov ntu kom tiv thaiv cov dej nkag mus ntxiv. Rau peb-core cable, nws yog ib qho nyuaj heev kom ua tiav tag nrho cov dej tsis kam ntawm cov tub ntxhais cable, vim hais tias qhov nruab nrab qhov sib txawv ntawm peb-core cable core yog loj thiab tsis xwm yeem, txawm tias siv cov dej thaiv, cov nyhuv dej tsis zoo, nws raug nquahu kom txhua tus tub ntxhais raug tsim tawm raws li cov qauv dej tsis sib haum, thiab tom qab ntawd lub cable yog tsim.
