Expansion Joint Cable Tais

Cable Tais Expansion Joints

Cable tray expansion pob qij txha (tseem hu ua "expansion devices") yog cov khoom tseem ceeb hauv cable tais tshuab. Lawv them nyiaj rau kev nthuav dav lossis kev hloov pauv ntawm cov kab hluav taws xob los ntawm kev hloov pauv kub, kev sib haum xeeb hauv tsev, kev co, thiab lwm yam, tiv thaiv kev puas tsuaj rau cov kab hlau phaj lossis cov kab hluav taws xob sab hauv vim muaj kev ntxhov siab ntau dhau thiab ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov khoom siv cable tais.

1. Kev them nyiaj rau Expansion thiab Deformation: Absorbs ntev hloov ntawm cable tais los ntawm ib puag ncig kub hloov (thermal expansion thiab contraction), los yog tshem tawm los ntawm lub tsev hais plaub los yog kev co (xws li cov khoom vibration los yog av qeeg), tiv thaiv lub cable tais ntawm twisting, tawg, los yog loosening ntawm kev sib txuas.

2. Kev Tiv Thaiv Kev Nyab Xeeb Cable: Tiv thaiv cov cables los ntawm kev ncab ntau dhau, nyem, lossis khoov vim raug yuam kom deformation ntawm cable tais, txo qhov kev pheej hmoo ntawm kev puas tsuaj los ntawm rwb thaiv tsev thiab luv luv Circuit Court.

3. Txhim kho qhov system ruaj khov: Ua kom muaj kev txuas ntxiv ntawm tag nrho cov khoom siv cable tais thiab hluav taws xob conductivity (xws li grounding continuity), tsis muaj kev cuam tshuam rau cable nteg thiab tom qab tu.

Ib tug raug cable tais expansion sib koom ua ke muaj cov hauv qab no core Cheebtsam:

Expansion Section: Tsim los ntawm ob qho kev zawv zawg cable tais profiles (xws li hom trough, hom ntaiv, hom tais), ua tiav kev nthuav dav thiab kev cog lus los ntawm kev sib tshooj lossis zes cov qauv.

Kev Txuas Cov Khoom Siv: suav nrog cov phaj flange, cov ntsia hlau sib dhos (rau kev txwv thiab kho, tso cai rau qee yam ntawm zawv zawg), thiab qhia grooves (kom ntseeg tau tias kev nthuav dav yog axial).

Cov ntsaws ruaj ruaj: xws li roj hmab strips los yog sealing strips, sau qhov khoob hauv qhov nthuav dav kom tsis txhob muaj plua plav, noo noo, thiab cov khoom txawv teb chaws nkag mus rau hauv lub tais cable.

Hluav taws xob Jumpers: tooj liab braided straps, tooj liab busbars, los yog galvanized steel phaj jumpers txuas ob kawg ntawm lub cable tais los xyuas kom meej lub continuation ntawm lub grounding system (lub cable tais feem ntau kuj ua hauj lwm raws li lub grounding hlau).

Raws li kev teeb tsa kev teeb tsa thiab cov qauv tsim, cov kev faib tawm ntau yog raws li hauv qab no:

1. Los ntawm Installation Direction:

Kab rov tav Expansion Joint: Siv rau kab rov tav nteg cable tais los them nyiaj rau kab rov tav expansion thiab contraction (feem ntau siv).

1. Vertical Expansion Joints: Siv rau vertically ntsia cable tais (piv txwv li, nyob rau hauv shafts) los them nyiaj rau ntsug xaav (yuav tsum tau ib tug qhia ntaus ntawv los tiv thaiv offset).

2. Los ntawm Hom Qauv:
Sliding Expansion Joints: Ua tiav qhov kev nthuav dav thiab kev cog lus los ntawm kev sib tshooj thiab zawv zawg ntawm ob kab tais kab. Cov qauv yooj yim, tus nqi qis, haum rau feem ntau cov xwm txheej.
Hinged Expansion Joints: Siv lub pob khawm rau ib txhij them nyiaj rau axial expansion thiab contraction thiab me me -angle deflection (piv txwv li, ntawm cable tais khoov lossis qhov chaw uas muaj qhov sib txawv me ntsis).

3. Los ntawm Khoom:
Matches cov khoom tseem ceeb ntawm lub tais cable. Cov ntaub ntawv muaj xws li steel (galvanized / hmoov coated), aluminium alloy, thiab fiberglass (FRP), haum rau ib puag ncig ib puag ncig, lub teeb yuag / corrosion- ib puag ncig tiv taus, thiab ib puag ncig corrosive heev (xws li cov nroj tsuag tshuaj, thaj chaw ntug dej hiav txwv).
 

1. Kev Txiav Txim Qhov Chaw Nruab Nrab:
Ua ntej kev teeb tsa ntawm cov ntu ncaj ncaj (dhau 30-50m, tshwj xeeb raws li kev qhia tshwj xeeb), ntawm lub tsev sib tham / nthuav tawm cov pob qij txha, ntawm cov ntsiab lus sib txuas ntawm cov txheej txheem sib txawv (piv txwv li, lub tsev tsim khoom thiab cov tsev pabcuam), thiab hauv thaj chaw uas muaj qhov kub thiab txias (piv txwv li, sab nraum zoov cable tais, chaw ua haujlwm kub).

2. Expansion/Contraction xam xam:
Tus nqi nthuav dav / kev sib cog lus yuav tsum tau tsim raws li qhov ntev ntawm lub tais cable thiab qhov kub ntawm qhov sib txawv. Cov mis yog: ΔL=× L × ΔT (yog cov kab sib txuas sib txuas ntawm cov khoom siv cable, xws li ≈12 × 10⁻⁶ /℃rau steel, ≈23 × 10⁻⁶ /℃rau aluminium alloy; L yog qhov ntev ntawm lub cable tais; L yog qhov ntsuas qhov ntev ntawm cable tais; Δent ~ 2℃feem ntau yog qhov kub thiab txias. , ie, ΔT=80℃).

3. Cov Kev Txhim Kho Tseem Ceeb:

• Free Expansion/Contraction: Thaum lub sij hawm installation, lub expansion seem yuav tsum tsis raug yuam kom kho. Xyuas kom nws tuaj yeem xaub dawb raws li axial kev taw qhia kom tsis txhob muaj kev cuam tshuam ntawm kev nthuav dav / kev sib cog lus los ntawm cov hlua khi lossis cov hlua khi.
• Hluav taws xob txuas ntxiv: Txuas ob qhov kawg ntawm qhov txuas txuas nrog jumper xov hlau (tooj liab braided daim kab xev hla- thaj tsam loj dua lossis sib npaug li 16mm²) kom ntseeg tau tias qhov av tiv thaiv tsawg dua lossis sib npaug li 4Ω (thaum lub phaj cable kuj ua haujlwm raws li cov xaim hauv av).
• Kev sib khi thiab kev tiv thaiv: Qhov khoob ntawm qhov txuas ntxiv yuav tsum tau ntim nrog cov sealant. Kev kho dej tsis zoo ntxiv (xws li txhim kho lub hau los nag) yog xav tau rau qhov chaw sab nraum zoov lossis qhov chaw ntub dej.
• Kev sib txuas thiab fastening: Bolts yuav tsum tau nruj rau lub zog torque kom ruaj khov yam tsis muaj kev txwv kev nthuav dav thiab kev cog lus (elongated oval bolt qhov tsim tau txais).
   

Dav siv nyob rau hauv ntau yam cable tais tshuab, tshwj xeeb tshaj yog nyob rau hauv cov nram no scenarios:

• Industrial Sector: loj factories, metallurgical rhiav, chemical industrial parks (siab kub, corrosive ib puag ncig);
• Tsev Sector: High-cov tsev nce siab, cov chaw lag luam (kev sib koom ua ke), cov kav dej hauv av (ntev ncaj);
• Cov xwm txheej tshwj xeeb: txuas hniav, tunnels, kev tsheb nqaj hlau thauj mus los (kev vibration, kub hloov pauv hnyav);
• Cov xwm txheej sab nraum zoov: Qhib-cov kab hluav taws xob cua (piv txwv li, chaw nres tsheb, chaw nres tsheb fais fab photovoltaic, qhov kub thiab txias sib txawv).

• Kev xaiv thiab Kev Sib Tw: Cov lus qhia tshwj xeeb (dav, qhov siab) ntawm qhov sib koom ua ke yuav tsum sib haum rau lub cev tseem ceeb ntawm lub phaj cable, thiab qhov nthuav dav yuav tsum ua kom tau raws li qhov kev xav tau ntawm kev hloov pauv siab tshaj plaws (feem ntau, cov khoom specifications suav nrog 50mm, 100mm, 150mm, thiab lwm yam expansion ranges).
• Kev tu tsis tu ncua: Txheeb xyuas qhov cuam tshuam hauv qhov zawv zawg ntawm qhov sib koom ua ke nthuav dav, kev laus ntawm cov ntsaws ruaj ruaj, thiab xoob ntawm cov xov hlau jumper kom ntseeg tau ntev - lub sijhawm ua haujlwm tau zoo. Nyob rau hauv cov ntsiab lus, cable tais expansion pob qij txha yog "buffer li" uas ua kom lub cable tais system adapts rau ib puag ncig kev hloov thiab zam cov qauv thiab cable puas. Lawv tsim, xaiv, thiab kev teeb tsa yuav tsum tau txiav txim siab raws li cov yam ntxwv xws li qhov kub thiab txias, kev sib haum xeeb, thiab kev co hauv cov xwm txheej tshwj xeeb kom ua tiav kev nyab xeeb thiab txhim khu kev qha cable nteg.
