TFFN cable (Thermoplastic Flexible Nylon Cable) yog ib hom kab siv dav siv hauv ntau yam kev siv hluav taws xob. Vim nws cov khoom siv hluav taws xob zoo heev, txhua yam muaj zog thiab kub tsis kam, TFFN cable yog dav siv hauv cov khoom siv hauv tsev, cov khoom siv hauv tsev, lub tsev hluav taws xob thiab lwm yam. Kab lus no yuav tshawb txog qhov hluav taws kub thiab kub tsis kam ntawm TFFN cable hauv qhov tob thiab txheeb xyuas seb cov khoom no ua lub luag haujlwm tseem ceeb hauv kev siv tswv yim.
1. Kev txhais thiab kev tsim kho ntawm TFFN cable
TFFN cable muaj cov neeg xyuas pib, txheej txheej rwb thaiv tsev thiab txheej txheej, thiab siv cov thermoplastic nylon (polyamide) ua cov khoom siv rwb thaiv tsev. Nws tus neeg xyuas pib feem ntau yog ua los ntawm tooj liab tsis muaj oxygen lossis tinned tooj liab. Cov khoom siv hluav taws xob zoo heev ntawm cov ntaub ntawv no ua rau TFFN cable los muab kev sib kis tam sim no ruaj khov hauv ntau yam kev sib txuas hluav taws xob. Cov txheej txheej rwb thaiv tsev ntawm lub cable yog ua los ntawm cov nylon thermoplastic, uas tsis yog tsuas yog muaj kev hnav zoo thiab yoog raws, tab sis kuj muab qhov kub thiab txias thiab tshuaj tiv thaiv corrosion.
2. Hluav taws kub tsis kam ntawm TFFN cable
Kev tiv thaiv hluav taws yog hais txog lub peev xwm ntawm cov kab hluav taws xob los tiv thaiv cov nplaim hluav taws yam tsis muaj hluav taws kub los yog ua kom muaj hluav taws xob txuas ntxiv tom qab hluav taws kub lossis kub ib puag ncig. Rau TFFN cables, hluav taws kub kuj tseem ceeb heev, tshwj xeeb tshaj yog nyob rau hauv qee qhov chaw muaj kev pheej hmoo siab xws li cov chaw tsim khoom, tsim hluav taws xob thiab cov chaw pej xeem.
2.1 Cov qauv hluav taws kub tsis kam ntawm TFFN cables
TFFN cables feem ntau ua tau raws li cov qauv thoob ntiaj teb thiab lub teb chaws hluav taws kub. Piv txwv li:
TS EN 1581:Qhov no yog US tus qauv uas qhia txog qhov hluav taws kub ntawm cov cables. TFFN cables feem ntau ua tau raws li tus qauv no, tuaj yeem tiv taus qhov kub ntawm lub sijhawm luv luv, thiab tuaj yeem tiv thaiv kev sib kis ntawm hluav taws thaum muaj hluav taws kub.
NFPA 70 (NEC):Txoj Cai Hluav Taws Xob Hauv Tebchaws Meskas xav kom txhua lub xov tooj hluav taws xob yuav tsum muaj hluav taws kub nyhiab hauv qee yam xwm txheej. TFFN cables feem ntau ua tau raws li cov kev cai no thiab tuaj yeem tswj tau qee yam hluav taws xob ua haujlwm thaum muaj hluav taws kub.

TFFN cables feem ntau tuaj yeem ua tau raws li qhov yuav tsum tau ua thiab tuaj yeem tswj tau cov khoom siv hluav taws xob rau lub sijhawm ntev hauv hluav taws.
2.2 Cov yam ntxwv tiv thaiv hluav taws ntawm TFFN cables
Qhov hluav taws kub tsis kam ntawm TFFN cables feem ntau muaj feem xyuam rau cov khoom ntawm nws cov txheej txheem thiab tag nrho cov qauv ntawm cov cable. Nylon, raws li cov khoom siv sab nrauv, tuaj yeem yaj los yog degrade ntawm qhov kub thiab txias, tab sis feem ntau nws tuaj yeem tiv taus cov nplaim taws rau lub sijhawm luv luv. Cov khoom siv nylon nws tus kheej muaj qee yam nplaim taws retardant, uas txhais tau hais tias nyob rau hauv hluav taws, TFFN cables tsis yooj yim rau hlawv thiab tuaj yeem txo qhov kev pheej hmoo ntawm hluav taws. Txawm hais tias nylon nws tus kheej tsis tuaj yeem nres qhov nplaim taws, hauv kev tsim, cov tuam txhab ntawm TFFN cables feem ntau siv lwm cov khoom siv hluav taws xob los txhim kho qhov hluav taws kub ntawm lub cable.
2.3 Kev txwv ntawm kev siv TFFN cables
Txawm hais tias TFFN cables muaj qee yam kev tiv thaiv hluav taws, lawv tsis haum rau kev raug mob mus ntev hauv qhov chaw kub kub kub. Nyob rau hauv qhov kub thiab txias, lub cable yuav puas. Yog li ntawd, rau kev siv mus sij hawm ntev nyob rau hauv ib puag ncig hluav taws, kev siv TFFN cables yuav tsum ua raws li cov cai tswj kev nyab xeeb, thiab cov cables tshwj xeeb uas tsim los rau kev tiv thaiv hluav taws kub (xws li cov hluav taws kub-resistant cables lossis mineral insulated cables) feem ntau yuav tsum tau xaiv.
3. Thaum tshav kub kub tsis kam ntawm TFFN cables
Thaum tshav kub kub tsis kam yog hais txog lub peev xwm ntawm cov cables kom tiv taus qhov kub thiab txias ib puag ncig yam tsis muaj kev ua haujlwm ntawm lub cev lossis tshuaj lom neeg degradation. Lub tshav kub tsis kam ntawm TFFN cables feem ntau yog qhov tseem ceeb hauv nws cov khoom siv thiab kev tsim khoom, uas txiav txim siab nws lub neej kev pabcuam thiab kev ntseeg siab hauv ntau qhov chaw ua haujlwm.
3.1 Kev khiav hauj lwm kub ntawm TFFN cables
Kev khiav hauj lwm kub ntawm TFFN cables yog ib qho tseem ceeb parameter rau lawv cov tshav kub tsis kam. Kev khiav hauj lwm kub ntawm feem ntau TFFN cables feem ntau yog:
Yam tsawg kawg nkaus ua haujlwm kub:-20 degree. TFFN cables tuaj yeem tswj tau qhov kev ua tau zoo txawm tias nyob rau hauv qhov kub thiab txias ib puag ncig thiab tsim nyog rau kev siv hluav taws xob hauv cov chaw txias lossis qhov chaw kub.
Ua haujlwm kub siab tshaj plaws:90 degree. Cov khoom siv rwb thaiv tsev (thermoplastic nylon) ntawm TFFN cables tuaj yeem ua haujlwm tau ntev hauv qhov chaw kub thiab txias, kom ntseeg tau tias cov cables tuaj yeem ua haujlwm txuas ntxiv hauv qhov kub thiab txias.
Rau qee qhov tshwj xeeb ntawm TFFN cables, lawv cov hluav taws xob tiv thaiv tuaj yeem ncav cuag 120 degree, thiab lawv tuaj yeem tiv taus qhov kub siab dua hauv lub sijhawm luv. Txawm li cas los xij, kev cuam tshuam ntev mus rau ib puag ncig ntau tshaj qhov ntsuas kub no tuaj yeem ua rau kev laus ntawm cov khoom siv rwb thaiv tsev, kev ua haujlwm tsis zoo, thiab txawm tias luv luv lossis hluav taws xob tsis ua haujlwm.
3.2 Yam cuam tshuam rau cov cua sov ntawm TFFN cables
Lub tshav kub tsis kam ntawm TFFN cables cuam tshuam los ntawm ntau yam, feem ntau suav nrog cov hauv qab no:
Cov khoom siv conductor:TFFN cables feem ntau siv tooj liab tsis muaj oxygen (OFC) ua cov khoom siv. Tooj liab muaj qhov zoo conductivity, uas tuaj yeem txo qhov poob tam sim no hauv cable thiab tsis txhob muaj cua sov ntau dhau.
Cov khoom siv rwb thaiv tsev:Thermoplastic nylon (polyamide), raws li cov ntaub ntawv tseem ceeb ntawm TFFN cables, muaj cov cua kub tsis kam thiab tuaj yeem ua haujlwm ntawm qhov kub siab dua. Lub tshav kub tsis kam ntawm cov ntaub ntawv nylon feem ntau tuaj yeem sib txawv ntawm 90 degree thiab 120 degree.
Tam sim no load:Qhov ntau dua qhov tam sim no xa los ntawm cable, qhov kub ntau yog generated, yog li qhov luaj li cas ntawm lub load tam sim no tseem yuav cuam tshuam ncaj qha rau qhov kub thiab txias ntawm lub cable. Overload tam sim no yuav ua rau lub cable kub nce thiab txawm ua rau puas tsuaj rau lub rwb thaiv tsev txheej.
3.3 Daim ntawv thov ntawm TFFN cables nyob rau hauv ib puag ncig kub
Vim nws cov cua kub tsis zoo, TFFN cables tsim nyog rau qee qhov chaw kub kub, xws li cov khoom siv hluav taws xob, khoom siv hauv tsev thiab cov khoom siv automation. Hauv cov cheeb tsam no, TFFN cables tuaj yeem ua haujlwm ruaj khov kom ntseeg tau tias cov khoom siv ua haujlwm zoo ib yam. Txawm li cas los xij, nyob rau hauv qhov kub thiab txias heev, xws li kub-kub rauv thiab boilers, TFFN cables yuav tsum tau ntxiv kev tiv thaiv los yog xaiv lwm yam cables nrog zoo dua tshav kub.
4. Kev tsom xam ntawm hluav taws kub thiab kub tsis kam ntawm TFFN cables
Qhov hluav taws kub tsis kam thiab kub tsis kam ntawm TFFN cables yog cov yam ntxwv tseem ceeb hauv kev siv tswv yim. Txawm hais tias nws muaj qee yam hluav taws kub thiab kub tsis kam, nws yuav tsum tau ua tiav raws li qhov sib txawv siv ib puag ncig thaum xaiv. Hluav taws kub tsis kam txiav txim siab seb TFFN cables tuaj yeem ua haujlwm txuas ntxiv hauv qhov hluav taws kub, thaum tshav kub kub txiav txim siab ua haujlwm ruaj khov ntawm cable nyob rau hauv qhov kub thiab txias. Thaum xaiv TFFN cables, cov neeg siv yuav tsum xav txog yam xws li qhov kub siab tshaj plaws ntawm lawv qhov chaw ua haujlwm, muaj peev xwm raug hluav taws kub, thiab qhov ntsuas hluav taws xob ntawm cov cable los xyuas kom meej lub sijhawm ntev thiab kev nyab xeeb ntawm cable.
4.1 Cov xwm txheej siv tau
Cov hluav taws kub thiab kub tsis kam ntawm TFFN cables ua rau lawv zoo heev rau:
Industrial khoom:Hauv cov khoom siv kub thiab nquag ua haujlwm, TFFN cables tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev.
Kev lag luam khoom siv hauv tsev:Txij li thaum cov khoom siv hluav taws xob hauv cov khoom siv hauv tsev feem ntau yuav tsum tau ua haujlwm nyob rau hauv qhov kub thiab txias, TFFN cables tuaj yeem muab kev tiv thaiv qhov kub thiab txias.
Lub tsev hluav taws xob:Hauv kev tsim cov tshuab hluav taws xob, TFFN cables tuaj yeem tiv taus qhov kev hloov pauv ntawm qhov kub thiab txias thiab haum rau kev siv hluav taws xob dav dav thiab cov teeb liab kis tau tus mob.
