MC Cable yog ib hom cable nrog tus thawj coj qhwv hauv lub hnab hlau, haum rau kev faib khoom, tswj kab, thiab hluav taws kub. Piv nrog AC (armored) cables, cov hlau riam ntawmMC Cabletuaj yeem ua ob qho tib si cov cuab yeej siv cov khoom siv hauv cov khoom siv thiab cov xov hlau insulated hauv av. Nws cov yam ntxwv tseem ceeb muaj xws li: 1. Durabe: Aluminium lossis hlau sheaths muab kev tiv thaiv ntau dua. 2. Yooj yim Installation: Tsis tas yuav muaj kev tsim kho ntxiv lossis cov ntaub ntawv tsim kho, tsim nyog rau cov chaw tsim kho thiab noo noo, thiab tuaj yeem nruab rau hauv av lossis raug ntsia.
Hauv ntau hom MC cables, txhua tus neeg xyuas pib cim nrog cov xim tshwj xeeb los xyuas kom meej cov kev ua haujlwm xaim hluav taws xob thaum lub teeb meem hluav taws xob thiab saib xyuas.Noj MC cable 12uasg ua piv txwv, piav qhia raws cov qauv xim cov xim muaj rau MC cables
1. Xim coding ntawm 12 2 mc cable
{{{0 {0}} MC cable feem ntau yog siv rau 120V lossis 277v kab, nrog cov ntawv thov raug suav nrog cov dej ci thiab cov teeb pom kev zoo. Nws muaj ob 12 lub ntsuas cua sov (AWG) thiab xim liab lossis ntsuab ntsuab hauv av sab hauv. Tus qauv xim coding yog raws li hauv qab no:
Dub (kub 1): theem tseem ceeb xaim xaim, cov hlau nyob txuas nrog lub zog hluav taws xob.
Nruab nrab: qhov nruab nrab ntawm cov hlau ua tiav cov voj voos.
Ntsuab lossis liab qab tooj liab (av): Cov xaim xaim hluav taws xob, muab kev tiv thaiv Circuit Court.
Hauv ib leeg-theem 120V lossis 277v siv, cov xov hlau dub txuas nrog cov hluav taws xob hauv Circuital, thiab cov xov hlau dawb tau ua ke kom ntseeg tau tias qhov kev nyab xeeb ntawm cov hluav taws xob kev nyab xeeb.
2. Xim coding ntawm 12 3 mc cable
{12 3 mc cables yog haum rau dual theem circuits nrog 208v, lossis rau ib leeg-theem 120V circuits uas yuav tsum tau hloov ywj pheej. Piv txwv li, nyob rau hauv lub chaw nyob thiab kev coj ua lag luam, thaum siv peb-theem fais fab mov, {} mc cables tuaj yeem siv los tswj ntau lub teeb. Cov xim coding yog raws li hauv qab no:
Dub (kub 1): kab paus tseem ceeb.
Liab (kub 2): theem ob nyob hlau, haum rau 240V cov khoom siv lossis dual hloov circuits.
Nruab nrab: nruab nrab hlau.
Ntsuab lossis liab qab tooj liab (av): galking hlau.
Thaum siv rau cov xov hlau 120V, cov xov hlau dub thiab liab tuaj yeem txuas rau cov hloov pauv sib txawv los tswj ob lub nra ywj pheej. Thaum siv rau cov xov hlau 240V, cov xov hlau dub thiab liab tau txuas nrog L1 thiab L2, muab ob-theem fais fab mov.
3. Cov xim coding ntawm 12 4 mc cable
{12 4 mc cable feem ntau yog siv rau {}}}}}}}}} pa fais fab mov system, lossis ntau dua cov khoom siv hloov chaw tswj. Cov xim coding yog raws li hauv qab no:
Dub (kub 1): thawj theem kub txoj kab.
Liab (kub 2): Thib ob theem nyob kab.
Xiav (kub 3): Thib peb theem nyob hlau.
Nruab nrab: nruab nrab hlau.
Ntsuab lossis liab qab tooj liab (av): galking hlau.
Qhov kev teeb tsa no tshwj xeeb tshaj plaws hauv kev ua lag luam thiab kev muaj zog, xws li muab lub zog rau peb-theem motors lossis rau of elevator tswj system nyob rau hauv cov vaj tse ntau zaj. Cov xov tooj dub, liab, thiab xiav nyob sib haum rau theem A, B, thiab C ntawm peb-theem thauj khoom xws li cov khoom siv hvac lossis cov khoom siv hvac.
4. Cov xim coding ntawm 12 5 mc cable
Lub 125 MC Cable Ntxiv ntxiv ib qho xaim xaim ntxiv, haum rau ntau cov tshuab hluav taws xob muaj 277 / 480V faib khoom, teeb tsa HVAC. Cov xim coding yog raws li hauv qab no:
Dub (kub 1): thawj theem kub txoj kab.
Liab (kub 2): Thib ob theem nyob kab.
Xiav (kub 3): Thib peb theem nyob hlau.
Txiv kab ntxwv (hauv av cais): Kev rho tawm cov hlau xaim hluav taws xob (siv rau cov khoom siv rhiab).
Nruab nrab: nruab nrab hlau.
Ntsuab lossis liab qab tooj liab (av): Khoom siv kob xaim xaim.
Cov tshuaj ntsuab txiv kab ntxwv feem ntau yog siv rau kev cais tawm hauv tsev (IG) thiab yog tsim rau ib puag ncig xws li lub suab kho mob thiab lub suab nrov hluav taws xob. Qhov kev teeb tsa no kom ntseeg tau tias cov cuab yeej tsis cuam tshuam los ntawm kev cuam tshuam hluav taws xob hauv hluav taws xob hauv hluav taws xob thiab txhim kho kev ua kom muaj zog.
5. Xim coding ntawm 14 2 Hluav Taws Kub Hluav Taws Mc cable
Qhov 14 2 Hluav Taws Kub Mc Cable yog tsim rau cov hluav taws kub thiab ua tau raws li kev yuav tsum tau muaj ntawm hluav taws kev tiv thaiv hluav taws xob. Vim kev ntseeg siab yuav tsum muaj ntawm hluav taws kub hluav taws, nws cov xim hlawv kuj tseem txawv ntawm cov neeg MC cable MC sib txawv:
Liab (FPLL Fais Fab Circuit Court): Hluav Taws Kub Teeb Kab Sib Kis Sib Kis Sib Kis (feem ntau nyob).
Dub (Rov qab Circuit): Circuit Court sib txuas cov xov hlau.
Ntsuab lossis liab qab tooj liab (av): galking hlau.
Hauv qee cov ntawv teev tshwj xeeb, 14 2 Hluav Taws Kub Mc cable tej zaum yuav teeb tsa liab thiab dawb, qhov twg:
Liab sawv cev rau lub tswb ntsuas kev sib kis.
Dawb sawv cev rau nruab nrab kab lossis rov qab cov paib.
Qhov kev teeb tsa no tsim nyog rau cov khoom siv xws li hluav taws kub kub, buzzers, teeb pom thaum muaj xwm ceev, thiab ntsuas pa taws.
Qhov tseem ceeb ntawmMC CableXim Coling
Kev txheeb xyuas cov xim coding ntawm MC yog qhov tseem ceeb rau cov hauv qab no:
Kev Nyab Xeeb: Tiv thaiv cov hluav taws xob tsis zoo los ntawm kev ua rau luv luv ntawm cov voj voog, hluav taws xob hluav taws xob, lossis hluav taws kub.
Ua raws: kom ua kom ua raws li NEC thiab cov cai tsim hauv zej zog.
Kev sib xws yooj yim: nws pab txhawb cov neeg thev naus laus zis kom paub sai sai thiab txo lub sijhawm daws teeb meem.
Cov Txheej Txheem Tau: Ua kom cov kab ke ntawm kev sib txawv ntau ntau ntau ntau ntau ntau ntau, theem, thiab cov hom phiaj tsis meej pem rau siv.
