Kodi Overhead Service Drop Cable Ndi Chiyani?

Zingwe zogwetsera ntchito zapamwamba ndi zingwe zomwe zimapereka zingwe zamagetsi zapanja. Ndi njira yatsopano yopatsira mphamvu pakati pa ma conductor apamwamba ndi zingwe zapansi panthaka, zomwe zidayamba kufufuza ndi chitukuko koyambirira kwa 1960s.

Zingwe zotsitsa ntchito zapamwamba zimapangidwa ndi wosanjikiza wotsekera komanso wosanjikiza woteteza, wofanana ndi njira yopangira zingwe zolumikizirana. Ngakhale kuti amatha kusokonezedwa ndi kusokonezedwa ndi kunja ndipo sizowoneka bwino, amagwiritsidwa ntchito kwambiri m'malo omwe zimakhala zovuta kuyala zingwe zapansi panthaka chifukwa cha kudalirika kwawo kwamagetsi, kukhazikika, komanso kukonza bwino.

Kodi timasankha bwanji chingwe chotsitsa chapamutu?

Mitundu itatu ya zingwe zogwetsera ntchito za aluminiyamu ndi duplex service drop cable, triplex service drop drop, and quadruplex service drop cable. Amasiyana malinga ndi kuchuluka kwa ma conductor ndi ntchito wamba. Tiyeni tikambirane mwachidule udindo wa aliyense wa izi.

Zingwe za Duplex service drop drops zokhala ndi ma conductor awiri zimagwiritsidwa ntchito pamizere yamagetsi yagawo limodzi pamapulogalamu a 120-volt. Amagwiritsidwa ntchito kawirikawiri pamakina owunikira kunja, kuphatikizapo kuyatsa mumsewu. Kuphatikiza apo, amagwiritsidwa ntchito nthawi zambiri pantchito yomanga ntchito kwakanthawi. Zosangalatsa- Makulidwe a chingwe chaku America cha duplex amatchedwa mitundu ya agalu, kuphatikiza setter, shepherd, and chow.

Zingwe zotsitsa ntchito za Triplex zokhala ndi ma kondakitala atatu zimagwiritsidwa ntchito kunyamula mphamvu kuchokera ku mizere yothandizira kupita kwa makasitomala, makamaka kumutu wanyengo. Apanso, zingwe zaku American triplex service drop zili ndi nkhani yosangalatsa ku dzina lawo. Amatchulidwa ndi mitundu ya nyama za m’nyanja, monga nkhono, nkhanu, ndi nkhanu. Mayina a chingwe akuphatikiza Paludina, Valuta, ndi Minex.

Zingwe zogwetsa mautumiki a Quadruplex okhala ndi ma kondakitala anayi adapangidwa kuti azipereka zingwe zamagetsi zamagawo atatu. Amagwirizanitsa ma transformer amagetsi okhala ndi mitengo, makamaka omwe ali kumidzi, ndi mitu ya utumiki wa wogwiritsa ntchito mapeto. Zingwe za Quadruplex zomwe zimadutsa zofunikira za NEC zimatchedwa mitundu ya akavalo, monga Gelding ndi Appaloosa.

Kupanga ma Aluminium Service Drop Cables

Ngakhale pali zolinga zosiyanasiyana komanso kuchuluka kwa ma kondakitala, mawaya onse amagetsi apamtunda amapangidwa mofanana. Oyendetsa zingwezi amapangidwa ndi aluminium alloy 1350-H19,6201-T81 kapena ACSR.

Amakhala ndi cholumikizira cholumikizira cha polyethylene XLPE chomwe chimapereka chitetezo chachikulu ku zoopsa zakunja. makamaka, ali ndi kukana kwambiri chinyezi, nyengo, ndi zotsatira za mankhwala osiyanasiyana. Kutentha kwa ntchito kwa zingwe za aluminiyamu zam'mwamba zokhala ndi kutsekereza kwa XLPE ndi 90 digiri Celsius. Nthawi zambiri, kutchinjiriza kwa polyethylene kumatha kuyikidwa m'malo mwa XLPE insulation. Pankhaniyi, kutentha kwa ntchito kumachepetsedwa kufika 75degrees, zomwe ndizofunikira kukumbukira poganizira za ntchito yanu yamagetsi. Mphamvu yamagetsi yamawaya onse amagetsi opitilira pamwamba ndi 600 volts.

Zingwe zonse za aluminiyamu zoponyera ntchito zimakhala ndi kondakitala wosalowerera kapena waya wa messenger. Cholinga cha messenger conductor ndikupanga njira yopanda ndale kuti magetsi athawe ndikupewa ngozi, zomwe ndizofunikira kwambiri pamayendedwe akunja. Mawaya a Messenger amatha kupangidwa ndi zinthu zosiyanasiyana, monga AAC, ACSR, kapena mtundu wina wa alloy aluminium.

Ngati mungafune kufunsidwa za ma conductor omwe amasiya ntchito, chonde titumizireni.
