Taw qhia rau BS 5308 Ntu 2 Hom 1 PVC/IS/OS/PVC Cable
I. Txheej txheem cej luam
BS 5308 Ntu 2 Hom 1 PVC / IS / OS / PVC Cable yog ib qho tshwj xeeb cable tsim los rau cov kev siv tshwj xeeb hauv kev sib txuas lus thiab tswj cov teeb liab kis tau tus mob. Nws yog tsim los ua kom tau raws li qhov yuav tsum tau muaj ntawm ntau hom kev teeb tsa, nrog rau kev tsom mus rau kev siv sab hauv tsev thiab ib puag ncig uas tiv thaiv kev siv tshuab tsis yog qhov kev txhawj xeeb tseem ceeb.
II. Daim ntawv thov
Teeb liab kis
Qhov no cable yog engineered los nqa ntau hom teeb liab, uas yog analogue, cov ntaub ntawv, thiab lub suab teeb liab. Cov teeb liab no tuaj yeem tau txais los ntawm ntau yam kev hloov pauv xws li lub siab sensors, ntsuas qhov sib thooj, thiab microphones. Nws ua haujlwm raws li qhov nruab nrab txhim khu kev qha rau kev xa cov teeb liab no hauv kev sib txuas lus thiab kev tswj hwm, ua kom muaj kev sib txuas tsis sib haum ntawm cov khoom sib txawv.
Sab hauv thiab qis - Kev Tiv Thaiv Ib puag ncig
Tshooj 2 Hom 1 cables feem ntau yog tsim los rau kev siv sab hauv tsev. Qhov no suav nrog kev siv hauv cov tsev ua haujlwm, cov chaw lag luam, thiab cov chaw tsim khoom hauv tsev. Nyob rau hauv cov cheeb tsam no, lub cable tsis raug rau cov neeg kho tshuab hnyav hnyav uas sab nraum zoov lossis qhov chaw muaj kev pheej hmoo siab tuaj yeem tshwm sim. Nws kuj tseem tsim nyog rau ib puag ncig uas kev tiv thaiv kev siv tshuab tsis yog qhov yuav tsum tau ua, vim nws tsis yog feem ntau raug cuam tshuam rau lub cev, kev puas tsuaj, lossis cov khoom sab nraum zoov.
Kev ruaj ntseg teeb liab
Lub cable raug tshuaj xyuas ib tus zuj zus, uas txhim kho cov teeb liab kev ruaj ntseg. Nyob rau hauv qhov chaw uas qhov kev ncaj ncees ntawm cov teeb liab kis tau yog qhov tseem ceeb, xws li hauv cov ntaub ntawv - kev sib txuas lus rhiab heev los yog kev tswj hwm, qhov kev tshuaj ntsuam no pab tiv thaiv kev cuam tshuam. Los ntawm kev tiv thaiv cov teeb liab los ntawm cov khoom siv hluav taws xob sab nraud, nws ua kom ntseeg tau tias analogue, cov ntaub ntawv, lossis lub suab teeb liab raug xa mus kom raug thiab tsis muaj kev cuam tshuam.
III. Yam ntxwv
Rated Voltage
Nrog rau qhov ntsuas hluav taws xob ntawm Uo / U: 300 / 500V, lub cable tau zoo - yoog mus rau ntau yam kev siv hluav taws xob ntsig txog kev sib txuas lus thiab tswj cov teeb liab hloov. Qhov ntsuas hluav taws xob no muab lub zog ruaj khov rau cov teeb liab uas nws xa tawm, ua kom muaj txiaj ntsig zoo ntawm cov khoom siv sib txuas.
Rated Kub
Lub cable muaj qhov ntsuas kub ntawm qhov sib txawv nyob ntawm nws lub xeev. Rau kev txhim kho ruaj khov, nws tuaj yeem ua haujlwm nyob rau hauv qhov kub ntawm -40ºC txog +80ºC, thaum lub sijhawm hloov pauv, qhov ntau yog los ntawm 0ºC txog +50ºC. Qhov kev ntsuas kub siab no tso cai rau nws siv rau hauv cov huab cua sib txawv hauv tsev, los ntawm cov chaw cia txias mus rau cov chav tsev sov so.
Yam tsawg kawg Bending Radius
Qhov tsawg kawg nkaus khoov vojvoog ntawm 6D yog ib qho tseem ceeb yam ntxwv. Qhov no kuj me me dabtsi yog khoov vojvoog qhia tau hais tias lub cable yuav bent ntau sharply piv rau lwm yam cables yam tsis muaj kev puas tsuaj rau nws sab hauv. Qhov no yog qhov muaj txiaj ntsig zoo thaum lub sijhawm teeb tsa, vim nws tso cai rau kev hloov pauv ntau dua hauv kev xa cov kab nyob ib ncig ntawm cov ces kaum thiab los ntawm qhov chaw nruj hauv kev teeb tsa sab hauv.
IV. Kev tsim kho
Tus coj
Rau qhov chaw hla nruab nrab ntawm 0.5mm² - 0.75mm², lub cable siv Class 5 hloov tau tooj liab conductors. Cov conductors no muaj kev hloov tau zoo heev, uas yog qhov zoo rau cov ntawv thov uas cov cable yuav tsum tau khoov lossis maneuvered hauv qhov chaw sab hauv. Rau thaj tsam ntawm 1mm² thiab saum toj no, Chav Kawm 2 stranded tooj liab conductors yog ua haujlwm. Lawv muab cov conductivity zoo thiab txhua yam muaj zog, ua kom cov teeb liab kis tau zoo.
Ua khub
Lub cable nta ob insulated conductors uas yog uniformly twisted ua ke. Qhov kev sib koom ua ke no pab txo qis kev sib tham ntawm cov neeg sib tham, uas yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees ntawm cov teeb liab kis, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas muaj ntau lub teeb liab tau nqa ib txhij.
Rwb thaiv tsev
PVC (Polyvinyl Chloride) rwb thaiv tsev yog siv nyob rau hauv no cable. PVC yog ib tug nqi - zoo thiab feem ntau siv cov khoom siv rau cable rwb thaiv tsev. Nws muab cov khoom hluav taws xob zoo rwb thaiv tsev, tiv thaiv hluav taws xob tawm thiab ua kom cov teeb liab kis tau yam tsis muaj kev cuam tshuam.
Kev tshuaj ntsuam
Tus neeg thiab tag nrho cov tshuaj ntsuam ua los ntawm Al / PET (Aluminium / Polyester daim kab xev) muaj kev tiv thaiv tiv thaiv electromagnetic cuam tshuam. Nyob rau hauv ib puag ncig sab hauv uas tej zaum tseem yuav muaj cov suab nrov ntawm electromagnetic, xws li cov khoom siv hluav taws xob lossis cov xaim hluav taws xob, qhov kev tshuaj ntsuam xyuas no yuav pab tswj cov teeb liab kis tau zoo.
Dej Hlau
Lub tinned tooj liab xaim xaim ua haujlwm rau dissipate cov nqi hluav taws xob uas tuaj yeem tsim rau ntawm lub cable. Qhov no pab txhim kho kev nyab xeeb thiab kev ua haujlwm ntawm lub cable los ntawm kev tiv thaiv cov teeb meem zoo li qub.
Sheath
Sab nrauv ntawm lub cable yog ua los ntawm PVC, uas muab ib txheej ntxiv ntawm kev tiv thaiv rau cov khoom siv sab hauv. Lub sheath xim ntawm xiav - dub tsis tsuas yog muab lub cable ib tug txawv tsos, tab sis kuj pab nyob rau hauv ib qho yooj yim txheeb xyuas thaum lub sij hawm installation.
