Cov xov hlau thiab cov cables yog ib feem tseem ceeb ntawm lub zog fais fab thiab siv los xa cov zog hluav taws xob thiab cov cim. Nyob ntawm qhov chaw siv thiab qhov xwm txheej ntawm daim ntawv thov, muaj ntau hom xov hlau thiab cable. Muaj cov xov hlau tooj liab liab qab, cov xov hlau fais fab, cov xov hlau rwb thaiv tsev, cov xov hlau tswj, cov xov hlau ntaub thiab cov xov hlau tshwj xeeb thiab lwm yam.
Ntxiv rau cov xov hlau thiab cov cable uas siv ntau tshaj plaws saum toj no, muaj qee cov xov hlau thiab cable tshwj xeeb, xws li xov hlau kub thiab cable, xov hlau thiab cable tiv taus corrosion, xov hlau thiab cable tiv taus hnav. Cov xov hlau thiab cable no muaj cov yam ntxwv tshwj xeeb thiab kev siv, tsim nyog rau cov xwm txheej siv thiab kev lag luam tshwj xeeb.
Hauv ntej, raws li kev siv sib txawv thiab cov xwm txheej ntawm daim ntawv thov, kev xaiv hom hlau thiab cable zoo tuaj yeem ua kom muaj kev nyab xeeb thiab ruaj khov ntawm lub zog fais fab. Tib lub sijhawm, qhov zoo thiab kev nyab xeeb ntawm hlau thiab cable kuj muaj feem cuam tshuam ncaj qha rau kev nyab xeeb ntawm cov khoom ntiag tug, yog li them sai sai rau kev xaiv cov hom lag luam ib txwm muaj thiab cov hlau thiab cable zoo txhim khu kev qha hauv cov txheej txheem ntawm kev siv. Cov hauv qab no piav qhia txog ntau hom hlau thiab cable thiab lawv cov yam ntxwv. Vam tias yuav pab koj nkag siab zoo dua lub ntsiab lus ntawm cov qauv qhia tshwj xeeb.
Thawj hom hlau thiab cable: hlau tooj liab liab qab
Cov khoom siv hlau liab qab thiab cov khoom siv hlau liab qab yog hais txog cov hlau conductive uas tsis muaj rwb thaiv tsev thiab hnab, feem ntau suav nrog cov hlau liab qab ib leeg, hlau liab qab thiab cov khoom peb series.
Tooj liab txhuas ib txoj hlau: suav nrog tooj liab mos ib txoj hlau, tooj liab tawv ib txoj hlau, txhuas mos ib txoj hlau, txhuas tawv ib txoj hlau. Feem ntau siv ua ntau yam hlau thiab cable semi-products, me me ntawm kev sib txuas lus hlau thiab cov khoom siv hauv lub cev muaj zog.
Cov hlau tsis muaj hlua khi: suav nrog cov hlau tooj liab tawv (TJ), hlau txhuas tawv (LJ), hlau txhuas hlau (LHAJ), hlau hlau txhuas hlau (LGJ) feem ntau yog siv rau kev sib txuas ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob lossis cov khoom siv, cov lus qhia ntawm ntau yam hlau hlua khi saum toj no yog txij li 1.0-300mm².
Hom thib ob ntawm cov hlau thiab cable: fais fab cable
Cov xov hluav taws xob hauv lub nraub qaum ntawm lub zog fais fab rau kev xa thiab faib cov khoom siv hluav taws xob siab, suav nrog 1 ~ 330KV thiab siab dua ntau qib voltage, ntau yam xov hluav taws xob rwb thaiv tsev.
Cov seem yog 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 630, 800mm², thiab tus lej tseem ceeb yog 1, 2, 3, 4, 5, 3 + 1, 3 + 2.
Cov xov hluav taws xob muab faib ua cov xov hluav taws xob tsawg, cov xov hluav taws xob nruab nrab, cov xov hluav taws xob siab thiab lwm yam. Raws li cov xwm txheej rwb thaiv tsev, cov xov hluav taws xob yas rwb thaiv tsev, cov xov hluav taws xob roj hmab rwb thaiv tsev, cov xov hluav taws xob ntxhia rwb thaiv tsev thiab lwm yam.
Hom thib peb ntawm cov hlau thiab cable: overhead insulated cable
Cov xov hlau overhead kuj yog ib qho uas pom ntau heev, nws yog ib yam uas tsis muaj lub tsho. Muaj ntau tus neeg muaj peb qhov kev nkag siab yuam kev txog cov xov hlau no. Ua ntej, nws cov xov hlau tsis yog tsuas yog txhuas xwb, tab sis kuj yog cov xov hlau tooj liab (JKYJ, JKV) thiab cov hlau txhuas (JKLHYJ). Tam sim no kuj muaj cov xov hlau hlau txhuas uas muaj cov xov hlau overhead (JKLGY). Qhov thib ob, nws tsis yog ib lub tub ntxhais xwb, feem ntau yog ib lub tub ntxhais xwb, tab sis nws kuj tseem muaj ntau tus xov hlau. Qhov thib peb, qib voltage ntawm cov xov hlau overhead yog 35KV thiab qis dua, tsis yog 1KV thiab 10KV xwb.
Hom hlau thiab cable thib plaub: tswj cable
Cov qauv cable no thiab lub hwj chim cable zoo sib xws, nws tsuas yog muaj tooj liab xwb, tsis muaj txhuas, qhov seem ntawm tus neeg xyuas pib me me, thiab muaj ntau lub cores, xws li 24 * 1.5, 30 * 2.5 thiab lwm yam.
Haum rau AC rated voltage 450/750V thiab qis dua, chaw tsim hluav taws xob, chaw hloov pauv, chaw tsuas, chaw tsim khoom siv roj av thiab lwm yam kev tswj hwm lossis kev tswj hwm cov khoom siv hauv chav tsev. Txhawm rau txhim kho lub peev xwm ntawm cov xov tooj tswj teeb liab kom tiv thaiv kev cuam tshuam sab hauv thiab sab nraud, feem ntau yog siv cov txheej tiv thaiv.
Cov qauv feem ntau yog KVV, KYJV, KYJV22, KVV22, KVVP. Lub ntsiab lus ntawm tus qauv: "K" tswj cable chav kawm, "V"PVCrwb thaiv tsev, "YJ"polyethylene txuas nrogrwb thaiv tsev, "V" PVC sheath, "P" tooj liab hlau tiv thaiv.
Rau cov txheej tiv thaiv, KVVP feem ntau yog cov hlau tooj liab tiv thaiv, yog tias nws yog cov hlau tooj liab tiv thaiv, nws yog qhia ua KVVP2, yog tias nws yog cov ntaub thaiv kab xev txhuas-yas sib xyaw, nws yog KVVP3.
Hom hlau thiab cable thib tsib: Tsev Wiring Cable
Feem ntau siv rau hauv tsev neeg thiab cov txee faib khoom, thiab feem ntau hais tias BV hlau yog cov xov ntaub. Cov qauv yog BV, BLV, BVR, RVV, RVVP, BVVB thiab lwm yam.
Hauv cov qauv sawv cev ntawm cov hlau thiab cable, B feem ntau pom, thiab ntau qhov chaw sawv cev rau ntau lub ntsiab lus sib txawv.
Piv txwv li, BVVB, qhov pib ntawm B yog lub ntsiab lus ntawm hlau, nws yog los qhia txog kev faib tawm ntawm daim ntawv thov ntawm lub cable, ib yam li JK txhais tau tias overhead cable, K txhais tau tias tswj cable. B ntawm qhov kawg sawv cev rau hom tiaj tus, uas yog qhov yuav tsum tau tshwj xeeb ntxiv rau lub cable. Lub ntsiab lus ntawm BVVB yog: tooj liab core polyvinyl chloride insulated polyvinyl chloride sheathed flat cable.
Hom hlau thiab cable thib rau: Cable tshwj xeeb
Cov cables tshwj xeeb yog cov cables uas muaj cov haujlwm tshwj xeeb, feem ntau suav nrog cov cables retardant hluav taws (ZR), cov cables tsis muaj pa luam yeeb tsawg halogen (WDZ), cov cables tiv taus hluav taws (NH), cov cables tsis tawg (FB), cov cables tiv taus nas thiab cov cables tiv taus kab ntsaum (FS), cov cables tiv taus dej (ZS), thiab lwm yam. Cov cables tiv taus hluav taws (ZR), cov cables tsis muaj pa luam yeeb tsawg halogen (WDZ): feem ntau yog rau cov tshuab hluav taws xob tseem ceeb thiab kev tswj hwm.
Thaum cov kab ntsib hluav taws, lub cable tsuas tuaj yeem hlawv hauv qab qhov kev ua ntawm cov nplaim taws sab nraud, cov pa luam yeeb me me, thiab cov roj teeb meem (halogen) hauv cov pa luam yeeb kuj me me heev.
Thaum lub nplaim taws sab nraud ploj mus, lub cable kuj tuaj yeem tua nws tus kheej, yog li ntawd qhov hluav taws rau tib neeg lub cev thiab kev puas tsuaj rau khoom vaj khoom tsev raug txo kom tsawg kawg nkaus. Yog li ntawd, hom cable no yog siv dav hauv petrochemical, hluav taws xob, metallurgy, tsev siab thiab cov chaw muaj neeg coob coob thiab lwm qhov chaw tseem ceeb.
Cov xov hluav taws xob tsis kam (NH): feem ntau yog siv rau cov tshuab hluav taws xob thiab tswj hwm tseem ceeb. Thaum muaj hluav taws kub, cov xov hluav taws kub tuaj yeem tiv taus qhov kub siab ntawm 750 ~ 800 ° C rau ntau tshaj 90 feeb kom ntseeg tau tias muaj kev xa hluav taws xob zoo thiab siv sijhawm txaus los tua hluav taws thiab txo kev puas tsuaj.
Thaum muaj tej lub sijhawm tshwj xeeb, cov khoom tshiab yeej ib txwm muaj los, xws li cov cables uas tiv taus hluav taws, cov cables uas tiv taus hluav taws, cov cables uas tsis muaj pa luam yeeb halogen tsawg/pa luam yeeb tsawg uas tsis muaj pa luam yeeb halogen tsawg, cov cables uas tiv taus kab ntsaum/nas tsis muaj kab, cov cables uas tiv taus roj/txias/kub/hnav, cov cables uas txuas nrog hluav taws xob, thiab lwm yam.
