Self-regulating cables yog: ib tug txheej txheem cej luam ntawm hom, tshwj xeeb tshaj yog los ua ke thiab kev txheeb xyuas

Electric cua sov tshuab hnub no yog heev txawv khoom thov. Lawv fashionable siv ob sab hauv tsev thiab nraum zoov. Ntawm kev txaus siab yog nws tus kheej-regulating cables. Lawv yog cov tsawg demanding rau hauv tus txheej txheem ntawm mounting thiab haus tsawg zog.

Lawv apparatus ua ntawv thov cov hauv paus ntsiab lus sib txawv ntawm cov pa resistive cables. Consumer xyuas los pab xaiv rau qhov uas haum version ntawm qhov khoom. Kws txawj qhia yuav ua li cas kom zoo zoo mount ib tug zoo li system. Qhov no yuav kom ib tug ntev thiab tsim cov kev pab lub neej.

General yam ntxwv

Nyob rau hauv tsos self-regulating cables yog heev uas zoo sib xws rau cov pa ntau ntau yam, tiam sis tsuas yog ib tug me ntsis flattened. Qhov no yog vim tus ntaus ntawv sawv cev los ntawm cov khoom. Qhov no daim ntawv tso cai rau koj kom haum snugly mus rau lub rhuab nto.

Feem ntau cov feem ntau, cov khoom uas yog siv rau cov cua kub kav, tso tsheb hlau luam, dej thiab txhob txhaws ntawm lub-ru tsev. Muaj tshuab rau cua sov kev kho ntawm sab hauv thiab txoj kev installation nyob rau hauv lub hauv av los yog khi. Lawv muab tso rau hauv cov kauj ruam los yog tsheb.

Cov kab kev los ntawm daim ntawv thov ntawm tej khoom no tsis tshua muaj ntau. Qhov kom zoo dua ntawm no cable yog hloov lub cua kub lub hwj chim thiab khov, nyob ntawm seb ambient kub. Yog li ntawd, xws li ib tug system tsis xav tau ib tug ntsuas: nws adapts nws tus kheej rau muaj mob.

hlau tsim

Self-regulating cua kub cable muaj ib tug tshwj xeeb tsim. Nruab nrab ntawm ob conductive nyob ntawm tej yog ib tug matrix ua los ntawm ib tug polymer khoom. Nws yog ua los ntawm cov pa roj carbon-raws li.

Thaum ib tug tej yam ntau yam kub decreases, lub conductive muaj peev xwm nce, ua cas cov tshav kub. Yog hais tias lub cable ib ncig heev sov, cov khoom hloov nws cov khoom, pib ib ob peb tswj yus tus kheej lub khiav ntawm hluav taws xob, ntsig txog, cua kub tau tsawg.

Lub sab hauv qauv yog kev tiv thaiv los ntawm ntau cov zoo li. Cov hlau screen yog yuav tsum tau rau grounding thiab tiv thaiv lub caij cua kub los ntawm cov neeg kho tshuab kev puas tsuaj. Lub sab sauv plhaub yog ua los ntawm PVC kuj yuav tsub kom cov durability ntawm cov khoom. Los ntawm cov chav kawm ntawv ntawm nws lub zog nyob rau hauv lub tej yam kev mob nyob rau hauv uas koj yuav siv lub system.

zoo

Self-regulating hlau muaj ob peb zoo. Yog hais tias peb los sib piv nws nrog rau cov resistive ntau ntau yam, nws yog ntau yooj yim rau koj khiav lag luam. Nws yeej tsis ntshai ntawm kub me ntsis thiab tsis tau muaj ib tug uniform kub tshaj rau tag nrho cov qhov ntev ntawm cov khoom.

Nws yuav tsum tau muab sau tseg tias tam sim no system yog tsis ntshai ntawm lub hwj chim surges. Nws yuav rov ua kevcai raus dej, raws li txwv mus rau qhov cua kub nyob ntawm tej. Qhov no yog tshwj xeeb yog ib qho tseem ceeb nyob rau hauv lub lwm ntawm lub cua sov yeeb nkab tshuab, lawv li qub.

Nrog ib tug tshwj xeeb tsim tej khoom yuav txiav mus rau hauv daim me me. Wherein qhov tsawg kawg nkaus ntev ntawm 10-15 cm. Them mloog mus rau cov uas duav txhua yam ntawm lawv cov daim ntawv thov, ib tug yuav hais tias nyob rau hauv lub nyob ze yav tom ntej nws tus kheej-regulating system yuav displace resistive.

installation ntawm lub system

Installation xa khoom koj yuav ua tau koj tus kheej. Nws yog tsim nyog los ua raws li cov khw muag cov lus qhia thiab cov tswv yim ntawm cov kws txawj. Mounting ntawm ib tug self-regulating cua kub cable tej zaum yuav muaj ob hom: hauv thiab sab nraud. Yog hais tias cov yeeb nkab twb nteg underground, tab sis nws yog tsim nyog los ntes, koj yuav tsum yuav ib tug system nrog ib tug tsim nyog rwb thaiv tsev kawm ntawv. Nws ntev yuav tsum phim qhov luaj li cas ntawm cov yeeb nkab.

Communications txoj kab uas hla tsum tsis pub tshaj 50 mm. Lub cable yog thawb mus rau hauv cov yeeb nkab thiab yog kev cob cog rua rau lub network.

Nyob rau hauv cov ntaub ntawv ntawm lwm mounting system uas txuas mus rau qhov chaw ntawm lub txhuas daim kab xev. Ces nws txiag ib tug tshwj xeeb rhaub. Yog hais tias ib tug me me txoj kab uas hla kev sib txuas lus thiab nyob ntawm tej nteg ca thiab sau raws nkaus Ii rau qhov ntev ntawm lub raj. Rau ib tug ncaj ntau viav vias lub cable khoom nyob ib ncig ntawm lawv. lub system ntev tshaj li qhov loj ntawm kev sib txuas lus.

Cua sov ntawm qhib qhov chaw

Self-regulating cable rau cov yeeb nkab feem ntau siv nyob rau hauv cov daus melting tshuab. Lawv yog tsau hauv lub txhob txhaws rau lub ru tsev. Nyob rau hauv tas li ntawd, ib co tshuab xws hauv paus ntsiab lus ntawm cov lag luam yuav tsum mounted rau hauv qab daus, du. Lawv hliv cov tshuaj thiab muaj xws li kev tshem tawm cov daus thiab cov dej khov ntawm cov chaw.

Loj heev rau tej thaj chaw muaj peev xwm yuav sov nrog xws li ib tug system. Khiav rau lub tsheb rooj, leem chaw nyob ze ntawm lub tsev kuj equip no txoj kev. Cov av nyob rau hauv lub tsev cog khoom yog rhuab los ntawm nws tus kheej-regulating systems. Lawv cov nqi yog siab tshaj hais tias ntawm ib cov pa cable, tab sis lub operating nqi yog tsawg.

Ntau ntawm lub hwj chim cable

Rau txhua hom ntawm tej yam kev mob uas tsim nyog los xaiv tus tsim nyog hwj chim cables yog nws tus kheej-regulating. Tsawg-kub systems yog haum rau sab hauv tsev installation. Lawv siab tshaj plaws cua kub yog 65 degrees. Yog li lawv cov nyiaj pab ntau tshaj hwj chim yog 15 W / m.

Rau de-icing, cov cua kub nruab nrab txoj kab uas hla cov kav dej, chutes yuav tsum yuav cov khoom uas muaj ib tug tshaj plaws cua kub 120 degrees. Lawv thickness 30 W / m.

Kom muaj chaw, cua sov loj inch kav thiab tso tsheb hlau luam cua sov hlau nce mus txog 190 degrees. Reserve hwj chim yog ces sib npaug zos rau 95 W / m. Tus nqi kuj yog nyob ntawm lub hwj chim cable. Xaiv lub tsis ncaj ncees lawm hom ntawm cable, koj yuav tau txais yog tsis tau tib yam tshwm sim, uas yog yuav tsum tau. Yog li ntawd, cov kev xaiv yuav tsum tau mus them.

nqi ntawm

Yuav kom yuav lub system sawv cev ntawm lub hom, yuav tau siv ntau tshaj cov nyiaj tsev neeg nyiaj txiag tshaj yuav ib tug pa cable. Tab sis yuav siv cov nqi them rau nws tus kheej zoo nkauj sai sai.

Self-regulating cable, tus nqi ntawm uas tau raug soj ntsuam nyob rau hauv lub chav peb lub teb chaws yog nyob ntawm tus ntoo khaub lig seem, thiab lub hwj chim ntawm lub chaw tsim tshuaj paus. Lub kim tshaj plaws yog cov ntau lawm ntawm cables nyob rau hauv Denmark. Lawv nqi yuav ncav cuag 700 rubles. 1 m. Nyeg producers yog tso system, lub starting nqi yog sib npaug zos rau 100 rubles. 1 m.

Lub ntev cov hlau no mas yuav kis, lub tsis tshua kim nws yuav raug nqi txhua txhua 'meter'. Nws yog tsim nyog los xav txog ua ntej koj muas.

neeg xyuas

Raws li neeg tawm tswv yim, niaj hnub no tus nrov tshaj plaws yog ib tug ob peb hom. Cov muaj xws li cov self-regulating cua kub cable Raychem, Ensto, Devi, Lavita.

Hauv cov yeeb nkab yog feem ntau, raws li cov tswv yim los ntawm cov neeg muas zaub, lub tuam txhab khoom uas siv Ensto (20 W / m) thiab Lavita (16 W / m). Sab nraum kev sib txuas lus yog tsim los Raychem khoom (10W / m). Lub Danish lub tuam txhab Devi ua ib tug ntau ntawm cov ntaub ntawv sau npe cables (9 W / m), tab sis nws yog tus nqi.

Qhov tseem tau nqi rau Ensto thiab Lavita nyob ntawm tej. Tsis tas li ntawd sau tseg rau hauv lub siab zoo ntawm cov khoom.

Lub Finnish lub tuam txhab Ensto kev khiav hauj lwm kav ntev yog tsis inferior mus Devi, tab sis cov khoom no yuav raug nqi npaum li cas cheaper. Yog li ntawd, muaj ntau yam tau txais kev pab xaiv cov ntawm no lub particular hom.

Tom qab tshuaj ntsuam lub ntaus ntawv cov khoom xws li self-regulating cables yuav raug thov lawv nyob rau hauv lub neej txhua hnub. Installation yog heev yooj yim ua koj tus kheej. Cov kev xaiv nyob rau hauv lub hwj chim ntawm cov khoom thiab cov tej yam kev mob ntawm nws daim ntawv thov. Nws yog ib heev zoo thiab check system. Nws yuav kav rau ntau xyoo, lawv cov tswv, muab qhov tseeb kev siv thiab installation.
