Lub caij nyoog tshiab ntawm kev lag luam lub zog tshiab lub zog thiab kev tiv thaiv cov khoom siv hluav taws xob, thiab cov khoom pov thawj zoo heev rau cov hluav taws xob siab rau cov hluav taws xob. Cov tsheb hluav taws xob siab rau hluav taws xob muaj cov kev xav tau siab hauv txhua qhov, thiab yuav tsum ntsib RoHSB tus qauv, thiab yuav tsum tau ntsib RoHSB tus qauv ul94V-0 tus qauv kev xav tau thiab kev ua tau zoo. Daim ntawv no qhia cov ntaub ntawv thiab kev npaj thev naus laus zis ntawm cov hluav taws xob ntau rau hluav taws xob.
1.Qhov khoom siv ntawm cov hluav taws xob siab
(1) Cov khoom siv coj los ntawm cable
Tam sim no, muaj ob cov ntaub ntawv tseem ceeb ntawm cov cab cab txheej: tooj thiab txhuas. Ob peb lub tuam txhab xav tias tus nqi sib txawv, ua kom zoo dua li cov khoom siv hluav taws xob, kom ua tiav cov txiaj ntsig zoo ib yam li tooj liab lub peev xwm lossis ua kom tus neeg tooj liab zoo tib yam li tooj liab. Yog li, tus nqi tsim khoom yog tau txais kev cawmdim heev. Txawm li cas los xij, feem ntau cov lag luam tseem ceeb tooj liab yog qhov kev ua tau zoo tshaj plaws, thiab tom qab ntawd feem ntau nqa khoom muaj txiaj ntsig, tsis tshua muaj hluav taws xob thiab muaj zog kev ntseeg tau. Tam sim no, kev xaiv ntawm tus neeg saib xyuas feem ntau siv lub teb chaws tus qauv 6%, lub cheeb tsam tooj liab tau qis dua 0.30) kom ntseeg tau tias qhov muag muag thiab tawv ntawm tooj liab monofilament. Cov lus 1 teev cov qauv uas yuav tsum tau ua rau cov khoom siv ntawm tooj liab feem ntau.
(2) insulating txheej cov ntaub ntawv ntawm cables
Sab hauv ib puag ncig hluav taws xob cov tsheb sib xyaw, ntawm kev xaiv ntawm cov ntaub ntawv insulation txheej, kom ntseeg tau tias muaj peev xwm xaiv tau yooj yim thiab dav siv. Tam sim no, feem ntau siv insulating cov ntaub ntawv yog polyvinyl chloride (PVC),Hla-Txuas Polyethylene (XLPE), silicone roj hmab, thermoplastic elastomer (TPE), thiab lwm yam, thiab lawv cov yam ntxwv tseem ceeb yog qhia hauv Rooj 2.
Ntawm lawv, pvc muaj cov hmoov txhuas, tab sis cov kev qhia ROHS txwv tsis pub siv, Mercurne) thiab lwm yam kev phom sij, silicone roj hmab, TPE thiab lwm tus neeg ua phooj ywg.
(3) CABLE DOMAFFING LEM KHOOM SIV
Daim thaiv thaiv txheej tau muab faib ua ob ntu: semi-ua kev tiv thaiv txheej txheej thiab braided shield txheej txheej. Lub ntim respi-conductive tiv thaiv cov khoom ntawm 20 ° C thiab tom qab kev txiav txim siab tseem ceeb los ntsuas cov kev pabcuam lub neej ntawm cov hluav taws xob siab. Cov ntaub ntawv semi-qhia txog cov ntaub thaiv npog cov ntaub thaiv nrog ethylene-propylene-propylene roj hmab (EPR), polyvinyl chloride (PVC), thiabPolyethylene (PE)raws cov ntaub ntawv. Nyob rau hauv rooj plaub uas cov khoom siv raw tsis muaj txiaj ntsig thiab kev tshawb fawb txog kev tshawb nrhiav cov khoom siv ntawm cov khoom tiv thaiv kev ua haujlwm los txhim kho kev ua tau zoo ntawm cable.
2. siv hluav taws xob voltage cable npaj cov txheej txheem
(1) Cov neeg ua haujlwm thev naus laus zis
Cov txheej txheem yooj yim ntawm cable tau tsim rau lub sijhawm ntev, yog li tseem muaj lawv tus kheej cov qauv tshwj xeeb hauv kev lag luam thiab kev lag luam. Nyob rau hauv tus txheej txheem ntawm xaim kos duab, raws li lub untwisting hom ntawm ib qho xaim xaim, uncinging stranding tshuab thiab untwisting / untwisting stranding tshuab. Vim tias lub siab crystallization kub ntawm tooj liab tus txiv neej, lub annealing kub thiab sijhawm rub tawm Monwire los txhim kho lub elongation thiab pob txha lov ntawm xaim kos duab. Tam sim no, tus ntoo khaub lig-txuas nrog polyethylene cable (XLPE) tau hloov pauv cov roj roj ntxiv ntawm 1 thiab 500kv voltage qib. Muaj ob qho kev coj ua ib qho kev sib tw ua cov txheej txheem rau XLPE cov qauv: Las cov kab ke thiab cov hlau sib txuas. Ntawm ib sab tes, cov hlau core tuaj yeem zam lub siab kub thiab kev kub siab rau cov raj xa hluav taws xob rau cov khoom siv hluav taws xob mus rau hauv cov khoom siv hlau thiab cov khib nyiab; Ntawm qhov tod tes, nws kuj tseem tuaj yeem tiv thaiv dej infiltration raws cov kev coj ua kom ntseeg tau tias kev ua haujlwm nyab xeeb ntawm kev ua haujlwm ntawm cable. Tus txiv neej tooj liab nws tus kheej yog ib qho qauv zoo nkauj stranding, rawg stranding tshuab, nws tuaj yeem ua kom cov neeg saib xyuas txheej txheem sib dhos.
(2) XLPE Cable Rwb thaiv tsev Ntau Lawm
Rau zus tau cov kev tsim hluav taws xob siab xlpe xlpe xlpe xlpe, catenary qhuav cross-txuas (CCV) thiab ntsug kom sib txuas (VCV) yog ob txoj kev sib tw.
(3) Cov txheej txheem Extrusion
Ua ntej no, cable cov tuam ntxhab siv cov txheej txheem cable thiab tom qab ntawd cov txheej txheem cable Thaum xyoo 1970, 1 + 2 peb-txheej txheej txheem cov txheej txheem tau tshwm sim hauv cov khoom siv hlau insulated thiab sab nraud tiv thaiv thiab rwb thaiv tsev kom tiav rau hauv ib qho txheej txheem. Cov txheej txheem ua ntej muab cov ntaub thaiv npog cov ntaub thaiv npog, tom qab luv luv (2 ~ 5m), thiab tom qab ntawd extrudes rwb thaiv tsev thiab rwb thaiv tsev rwb thaiv tsev tib lub sijhawm. Txawm li cas los xij, thawj ob txoj kev muaj cov drawbacks zoo, yog li hauv cov khoom siv cov khoom siv ntau lawm, cov kev thaiv cov ntaub thaiv thiab rwb thaiv tsev thiab rwb thaiv tsev thiab rwb thaiv tsev. Ob peb xyoos dhau los, txawv teb chaws kuj tau tsim ib lub sijhawm tshiab ntxiv, hloov cov khoom sib txuas ntawm lub taub hau kev tsim qauv ntawm lub taub hau tsim tau kuj tseem txuag cov nqi downtime thiab txhim kho kev ua haujlwm.
3. Xaus
Lub zog hluav taws xob tshiab muaj kev txhim kho zoo thiab muaj peev xwm loj, kev ua haujlwm siab thiab lwm yam kev ua haujlwm tau zoo heev rau kev ua lag luam. Fais Tsheb Lub Tsheb High-voltage cable khoom thiab nws cov txheej txheem npaj muaj kev pab cuam tiag rau kev txhim kho. Lub tsheb hluav taws xob tsis tuaj yeem txhim kho ntau lawm thiab ua kom cov kev nyab xeeb uas tsis muaj kev tiv thaiv qib siab.
