Dab tsi yog ABC Cable?

Yog tias koj tau pom cov xim, cov xov hlau sib txuas rau cov nqi hluav taws xob (es tsis txhob pom cov xov hlau qub, koj yuav tau pom ABC cable. Nws yog cov tsiaj ntawv luv ntawm "Overhead Poothead Cable" thiab yog cov feem ntau siv rau kev faib hluav taws xob vim nws muaj kev nyab xeeb, chaw nyob hauv nroog, nroog thaj chaw me me.

Dab tsi yog nws?

ABC Cable ua ke 2 txog 4 insulated xaim rau hauv ib tug qauv compact. Tsis zoo li cov xov hlau nyiaj laus (uas raug rau huab cua thiab phom sij), txhua tus xaim hluav taws xob nrog cov ntaub ntawv ruaj khov xws li} Txuas Polyethylene (XLPE) lossis polyethylene (PE). Feem ntau yog qhov tsim nyog rau qhov tsawg rau nruab nrab voltage hluav taws xob hluav taws xob (0.6 / 1 kilovolt rau cov tsev me me) thiab feem ntau suav nrog ib lub tsev loj loj) thiab feem ntau suav nrog cov qauv me me "los txhawb nqa cov qauv hloov pauv thiab rov qab tam sim no. Cov xov hlau feem ntau ua los ntawm txhuas (lub hnab tawv thiab pheej yig) lossis tooj liab (zoo dua rau kev tshaj lij lossis hauv ntug hiav txwv).

Vim li cas tib neeg thiaj xaiv nws?

Nws qhov txiaj ntsig zoo tshaj plaws nyob rau ib qho teeb meem ntawm cov xov hlau qub:

Kev Nyab Xeeb Ua Ntej: Cov rwb thaiv av txheej txhais tau tias yog cov roj av, yuav tsis muaj kev pheej hmoo ntawm cov pej xeem nrog cov menyuam yaus lossis cov nroj tsuag ntom ntom ntom nti.

Tus txij nkawm tsawg: nws tuaj yeem tiv thaiv ultraviolet rays, nag, thiab txawm tias ua liaj ua teb. Nws lifespan yog 25 txog 30 xyoo (piv rau 15 txog 20 xyoo rau cov xov hlau liab), thiab nws txo cov kev xav tau txij li 40%.

Kev teeb tsa yog yooj yim: Pre {-} packaged wires txuag lub sijhawm {}}}} Tsis xav tau xaim txhua tus ib leeg zuj zus. Lub Hnav Me Me Tsim tso cai rau cov ncej me me lossis ntau qhov kev sib tw, yog li txuag nqi.

Tsawg lub zog hluav taws xob: cov ntaub ntawv insulating tiv thaiv luv luv tshwm sim los ntawm cov khib nyiab lossis cua, cov tuam txhab hluav taws xob txhim khu kev txhawb siab txo qis los ntawm 30% rau 50%).

Qhov twg nws ua haujlwm zoo tshaj?

Nws tsis yog ib qho siv tau thoob ntiaj teb, tab sis nws txawj ua tiav hauv cov chaw hauv qab no:

Thaj chaw (nyob deb nroog / nyob rau nroog): Kev lag luam ntau dua ntau dua li cov cables hauv av thiab muaj kev nyab xeeb dua li cov xov hlau (haum rau vaj).

Farm: Resistant to tractors, fertilizers, and adverse weather - harmless to livestock.

Kev ua lag luam me me: Muaj peev xwm tuav cov ntawv sau npe nyiaj ntsuab, cov khoom siv kho cua txias, thiab cov khoom siv teeb pom kev zoo hauv cov khw muag khoom lossis chaw haujlwm, thaum ua kom thaj chaw huv si.

Cov chaw nquag rau cua daj cua dub: ruaj khov kom muaj cov cua thiab khib nyiab, yog li nws yuav rov qab ua kom nrawm dua tom qab kev puas tsuaj.

Li cas los xaiv cov xaim xaim?

Ua cov tshev hauv qab no rau kev yooj yim:

Match Voltage: 0.6 / 1 kilovolt rau cov tsev, 10 kilovolt rau cov lag luam me (sab laj rau koj lub tuam txhab fais fab rau cov chaw tshwj xeeb hauv zos).

Xaiv tus neeg kos npe: feem ntau siv txhuas; Yog tias siv sijhawm ntev dua, kev tiv thaiv dej hiav txwv, lossis kev co ua kom xav tau, siv tooj liab. Rwb thaiv tsev yog ib qho tseem ceeb: Xaiv Cross -}}}}} linkylhlene (tuaj yeem tiv taus lub zog 90 degree) hloov ntawm polyethylene ntev.

Buy from reliable suppliers: Look for IEC/ANSI/BS certified products - uncertified cheap cables will soon break down.

Sai sai Dobunk Qee cov Myths

"Tsuas yog rau thaj chaw deb nroog?" Tsis muaj {- nws cov qauv kev cog lus tuaj yeem siv rau hauv cov chaw ua haujlwm ib yam nkaus.

"Kim dhau lawm?" Thawj tus nqi yog qhov siab dua me ntsis, tab sis cov nyiaj khaws cia hauv kev saib xyuas thiab hwj huam tuaj yeem muab suav ua ntej 10 txog 15 xyoos.

"Tsis tuaj yeem siv lub nra hnyav?" Siab - voltage versions (txog li 33 kikeat) haum rau cov peev txheej me me.

Hauv ntej, ABC Cable yog ib tug ntse dua, kev ua haujlwm ntawm kev siv fais fab. Lub sijhawm tom ntej koj pom cov xov xwm txuas ntxiv ntawm tus ncej, koj yuav paub - nws yog kev nyab xeeb ntawm lub nra hnyav.
