Cov hlau thiab cables yog ib feem tseem ceeb ntawm lub zog hluav taws xob thiab siv los xa hluav taws xob hluav taws xob thiab cov teeb liab. Nyob ntawm kev siv ib puag ncig thiab daim ntawv thov scenario, muaj ntau hom hlau thiab cable. Muaj cov xov tooj tooj liab liab, lub zog hluav taws xob, hluav taws xob hluav taws xob hluav taws xob, hluav taws xob hluav taws xob, tswj cov kab hluav taws xob, cov ntaub xov hlau thiab cov cable tshwj xeeb thiab lwm yam.
Ntxiv rau qhov saum toj no cov hlau thiab cable hom, muaj qee qhov tshwj xeeb xaim thiab cable, xws li kub kub thiab cable, corrosion resistant hlau thiab cable, hnav-resistant hlau thiab cable. Cov xov hlau thiab cables muaj cov khoom tshwj xeeb thiab kev siv, tsim nyog rau cov ntawv thov tshwj xeeb thiab kev lag luam.
Hauv luv luv, raws li qhov sib txawv siv ib puag ncig thiab daim ntawv thov scenarios, xaiv txoj cai ntawm cov hlau thiab cable tuaj yeem ua kom muaj kev nyab xeeb thiab ruaj khov ntawm lub zog hluav taws xob. Nyob rau tib lub sijhawm, kev ua tau zoo thiab kev nyab xeeb ntawm cov xaim thiab cable kuj tseem cuam tshuam ncaj qha rau kev nyab xeeb ntawm tus kheej cov cuab yeej, yog li ua tib zoo xaiv cov hom tsis tu ncua thiab txhim khu kev qha zoo ntawm cov xaim thiab cable hauv cov txheej txheem ntawm kev siv. Cov hauv qab no piav qhia txog ntau hom hlau thiab cable thiab lawv cov yam ntxwv. Cia siab tias yuav pab koj nkag siab zoo dua lub ntsiab lus ntawm tus qauv specification.
Thawj hom hlau thiab cable: liab qab tooj liab hlau
Cov khoom lag luam liab qab thiab cov khoom lag luam liab qab xa mus rau cov xaim hluav taws xob tsis muaj rwb thaiv tsev thiab cov ntaub qhwv, feem ntau suav nrog cov hlau tsis muaj ib leeg, cov hlau tsis muaj hlua khi thiab cov khoom peb series.
Copper aluminium ib xaim: suav nrog cov tooj liab ib leeg, tawv tooj liab ib xaim, mos aluminium ib xaim, tawv aluminium ib xaim. Feem ntau siv los ua ntau yam ntawm cov xaim thiab cable semi-cov khoom, me me ntawm kev sib txuas lus hlau thiab cov khoom siv lub cev muaj zog raug tsim.
Cov hlau tsis muaj hlua khi: suav nrog cov tooj liab tawv tawv hlau (TJ), tawv txhuas hlau xaim (LJ), txhuas hlau stranded hlau (LHAJ), steel core aluminium stranded 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 cov lus saum toj no ntau yam stranded wires ranges ntawm 30.2mm.
Qhov thib ob hom hlau thiab cable: fais fab cable
Fais fab cable nyob rau hauv lub caj qaum ntawm lub hwj chim system rau kev sib kis thiab kev faib khoom ntawm high-power fais fab cable khoom, xws li 1 ~ 330KV thiab saum toj no ntau theem voltage, ntau yam rwb thaiv tsev fais fab cables.
Qhov loj yog 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70, 95, 120, 150, 185, 240, 300, 400, 500, 630, 800mm², 45, cores 3 + 1, 3 + 2.
Fais fab cables tau muab faib ua cov kab hluav taws xob tsawg, nruab nrab voltage cables, high voltage cables thiab lwm yam. Raws li cov txheej txheem rwb thaiv tsev tau muab faib ua cov yas insulated cables, roj hmab insulated cables, ntxhia insulated cables thiab lwm yam.
Qhov thib peb hom hlau thiab cable: nyiaj siv ua haujlwm insulated cable
Nyiaj siv ua haujlwm cable kuj muaj ntau heev, nws yog yam ntxwv tsis muaj lub tsho. Ntau tus neeg muaj peb txoj kev xav tsis zoo txog cov kab no. Ua ntej, nws cov conductors tsis yog tsuas yog txhuas, tab sis kuj tooj liab conductors (JKYJ, JKV) thiab txhuas alloys (JKLHYJ). Tam sim no kuj tseem muaj cov tub ntxhais hlau aluminium stranded overhead cables (JKLGY). Qhov thib ob, nws tsis yog ib qho tseem ceeb xwb, feem ntau yog ib qho tseem ceeb, tab sis nws tuaj yeem tsim los ntawm ntau tus neeg xyuas pib. Qhov thib peb, qhov voltage ntawm cov nyiaj siv ua haujlwm cable yog 35KV thiab qis dua, tsis yog 1KV thiab 10KV xwb.
Plaub hom hlau thiab cable: tswj cable
Cov qauv ntawm cov kab hluav taws xob thiab lub zog hluav taws xob no zoo sib xws, yog qhov tshwj xeeb ntawm cov tub ntxhais tooj liab nkaus xwb, tsis muaj txhuas core cable, tus neeg xyuas pib hla ntu me me, cov cores ntau dua, xws li 24 * 1.5, 30 * 2.5 thiab lwm yam.
Haum rau AC rated voltage 450/750V thiab hauv qab no, chaw nres tsheb fais fab, substations, mines, petrochemical tuam txhab thiab lwm yam kev tswj ib leeg lossis chav tswj cov khoom siv. Txhawm rau txhim kho lub peev xwm ntawm kev tswj cov teeb liab cable los tiv thaiv kev cuam tshuam sab hauv thiab sab nraud, kev tiv thaiv txheej feem ntau yog siv.
Cov qauv yog KVV, KYJV, KYJV22, KVV22, KVVP. Qauv lub ntsiab lus: "K" tswj cable chav kawm, "V"PVCrwb thaiv tsev, "YJ"crosslinked polyethylenerwb thaiv tsev, "V" PVC sheath, "P" tooj liab hlau thaiv.
Rau cov ntaub thaiv npog, feem ntau KVVP yog tooj liab hlau thaiv, yog tias nws yog tooj liab daim thaiv npog, nws tau qhia tias yog KVVP2, yog tias nws yog aluminium-yas sib xyaw daim kab xev, nws yog KVVP3.
Qhov thib tsib ntawm cov hlau thiab cable: Lub Tsev Hluav Taws Xob Cable
Feem ntau siv nyob rau hauv tsev thiab faib khoom, thiab feem ntau hais tias BV hlau belongs rau ntaub xov hlau. Cov qauv yog BV, BLV, BVR, RVV, RVVP, BVVB thiab lwm yam.
Hauv cov qauv kev sawv cev ntawm cov hlau thiab cable, B feem ntau pom, thiab qhov chaw sib txawv sawv cev rau cov ntsiab lus sib txawv.
Piv txwv li, BVVB, qhov pib ntawm B yog lub ntsiab lus ntawm cov xaim, nws yog los qhia txog kev faib cov ntaub ntawv cable, ib yam li JK txhais tau hais tias nyiaj siv ua haujlwm cable, K txhais tau tias tswj cable. B ntawm qhov kawg sawv cev rau hom tiaj tus, uas yog ib qho kev xav tau tshwj xeeb ntxiv rau lub cable. Lub ntsiab lus ntawm BVVB yog: tooj liab tub ntxhais polyvinyl chloride insulated polyvinyl chloride sheathed ca cable.
Hom thib rau ntawm hlau thiab cable: tshwj xeeb cable
Cov kab hluav taws xob tshwj xeeb yog cov kab hluav taws xob uas muaj cov haujlwm tshwj xeeb, feem ntau suav nrog cov nplaim hluav taws xob hluav taws xob (ZR), cov pa hluav taws xob tsis muaj hluav taws xob tsis muaj hluav taws xob (WDZ), hluav taws kub-resistant cables (NH), hluav taws kub-pov thawj cables (FB), rat-proof cables thiab termite-proof cables (FS), dej-resistant cables (ZS), thiab lwm yam. Flame retardant cables (ZR) tseem ceeb rau cov pa hluav taws xob (ZR) tsis tshua muaj hluav taws xob cable (ZR) fais fab thiab tswj systems.
Thaum cov kab ntsib hluav taws, lub cable tsuas tuaj yeem hlawv nyob rau hauv qhov kev txiav txim ntawm cov nplaim hluav taws sab nraud, cov pa luam yeeb me me, thiab cov pa phem (halogen) hauv cov pa luam yeeb kuj tsawg heev.
Thaum cov nplaim hluav taws sab nraud ploj mus, lub cable kuj tuaj yeem tua nws tus kheej, kom qhov hluav taws kub rau tib neeg lub cev thiab cov khoom puas tsuaj raug txo kom tsawg. Yog li ntawd, hom kab no yog siv dav hauv petrochemical, hluav taws xob hluav taws xob, metallurgy, cov tsev siab siab thiab cov neeg nyob ruaj khov thiab lwm qhov chaw tseem ceeb.
Refractory cable (NH): feem ntau haum rau tshwj xeeb tseem ceeb lub zog thiab tswj cov tshuab. Thaum cov kab yog hluav taws kub, cov hluav taws kub-resistant cable tuaj yeem tiv taus qhov kub ntawm 750 ~ 800 ° C rau ntau tshaj 90 feeb los xyuas kom meej tias muaj kev nyab xeeb hluav taws xob kom muaj kev sib ntaus sib tua hluav taws txaus thiab lub sij hawm txo kev puas tsuaj.
Nyob rau hauv lub ntsej muag ntawm tshwj xeeb zaus, cov khoom tshiab tau los tas li, xws li hluav taws kub-resistant cables, hluav taws kub-retardant cables, tsis tshua muaj pa taws halogen dawb / tsawg-tsim tsawg-halogen cables, termite-proof/rat-proof cables, roj / txias / kub / hnav-resistant cables, hluav taws xob cross-linked cables, thiab lwm yam.
