Zoopsa za Chinyezi cha Chingwe ndi Kapangidwe Kapamwamba Kosalowa Madzi

Pambuyo pa mvula yamphamvu, magetsi ofunikira kwambiri mu sitima yapansi panthaka mumzinda adalephera. Atayang'ana chingwecho, nyumba zazikulu zamitengo yamadzi zidawonedwa mu insulation ya XLPE, ndipo dzimbiri lidawonekera pamwamba pa conductor yamkuwa. Chinyezi chidalowa mu chingwecho kudzera m'malekezero, malo olumikizirana, kapena m'chimake chowonongeka, zomwe zidapangitsa kuti insulation iwonongeke komanso kuti conductor iwonongeke, zomwe zidakhudza kwambiri kudalirika kwa chingwecho kwa nthawi yayitali.

Kulowa kwa Madzi

Chinyezi chingalowe mu chingwe kudzera m'malekezero kapena malo olumikizirana osatsekedwa bwino, kuwonongeka kwa makina kapena ming'alu yokalamba mu chikwama, kukhuthala kwakukulu kwa zinthu zotetezera madzi kapena chikwama, komanso chinyezi chotsalira mkati mwa chikwama kapena zigawo zotetezera kuchokera ku njira yopangira. Pa zingwe zapakati ndi zapamwamba, kulowa kwa madzi kumabweretsa kupangika kwa mitengo yamadzi mkati mwa chikwama cha XLPE, chomwe chimatha kukhala mitengo yamagetsi pansi pa minda yamagetsi yambiri, zomwe pamapeto pake zimayambitsa kuwonongeka kwa chikwama. Chinyezi chingawonongenso ma conductor a mkuwa kapena aluminiyamu, kuwonjezera kukana kukhudzana, kuyambitsa kutentha kwambiri, kuchepetsa kukana kwa chikwama, kuwonjezera mphamvu yotuluka, kuyambitsa zolakwika za nthaka pazochitika zazikulu, ndikufulumizitsa kukalamba kwa zinthu zotetezera ndi chikwama, kufupikitsa nthawi yogwira ntchito ya chingwe.

Chitetezo cha Chinyezi

Zingwe zamakono zapakati ndi zochepa zamagetsi zimadalira zipangizo za chingwe zogwira ntchito kwambiri kuti zipange njira zotchingira madzi zozungulira komanso zozungulira. Zotchingira madzi zozungulira zimagwiritsa ntchito zigoba za lead, zigoba za aluminiyamu zolumikizidwa, zigoba zamkuwa, kapena tepi ya aluminiyamu-pulasitiki (AL/PET) yokhala ndi kapangidwe ka chigoba chakunja cha PE, zomwe zimapereka chitetezo chamakina komanso kukana chinyezi chozungulira. Zotchingira madzi zozungulira zimagwiritsa ntchito matepi otupa madzi,ulusi wotchinga madzindi ma phala ozungulira ma cable cores, ndi ufa woteteza madzi wochokera ku polymer (SAP) kapena matepi oikidwa pakati pa ma conductor ndi ma cable cores. Zipangizozi zimakula zikakhudzana ndi madzi kuti zipange chotchinga chakuthupi, zomwe zimathandiza kupewa kusamuka kwa chinyezi komanso kupereka chitetezo chachiwiri cha XLPE insulation ndi LSZH sheath materials.

Kapangidwe ka Chingwe Chosagwira Chinyezi

Chingwe chodziwika bwino chotchinga madzi chapakati chimakhala ndi ma conductor a mkuwa kapena aluminiyamu, zigawo zotchinga zotulutsa mpweya zomwe zimayendetsedwa ndi semiconductive extruded, XLPE insulation, gawo lotchinga madzi lotalika (tepi yotchinga madzi/ ulusi usanalowetse chinsalu chachitsulo), chinsalu chachitsulo, tepi yolumikizidwa ya aluminiyamu-pulasitiki yolumikizidwa ngati chinsalu chakunja, ndi HDPE kapena zipangizo za polyolefin zoletsa moto. Kapangidwe kameneka kamapereka njira yotetezera chinyezi cha radial ndi chachitali. Kukhazikika ndi magwiridwe antchito a chingwe chilichonse kumatsimikizira mwachindunji chitetezo ndi moyo wa chingwe m'malo ovuta.

Kukhazikitsa ndi Kusamalira

Chitetezo chabwino cha chinyezi chimadaliranso kuyika ndi kukonza bwino. Kutseka ndi kulumikizana kuyenera kugwiritsa ntchito zipangizo zotsekera zoyenera komanso zapamwamba monga kutentha-kuchepa, kuzizira-kuchepa, kapena epoxy sealants kuti zitsimikizire kutseka kodalirika. Pakuyika, chidebecho chiyenera kutetezedwa ku kuwonongeka kwa makina, ndipo mphamvu zakunja ziyenera kupewedwa panthawi yogwira ntchito. Kuyeza nthawi zonse kukana kutenthetsa ndikofunikira kuti muwone momwe chinyezi chilili mu XLPE insulation ndi zipangizo za LSZH sheath. Makina amakono a chingwe amathanso kuphatikiza zida zowunikira za sheath kuti zipereke machenjezo enieni a kulowa kwa chinyezi.

Matepi otchingira madzi ogwira ntchito bwino kwambiri, ulusi/ma phala otchingira madzi, zipangizo za chikwama chapamwamba kwambiri, kapangidwe koyenera ka nyumba, ndi kukhazikitsa kokhazikika ndizofunikira kwambiri kuti zingwe zikhale zodalirika kwa nthawi yayitali. Monga wogulitsa zinthu za chingwe waluso, ONE WORLD imapereka kutchinjiriza kwapamwamba kwa XLPE, zipangizo za chikwama cha LSZH, matepi otchingira madzi, ulusi/ma phala otchingira madzi, ndi matepi ophatikizika a aluminiyamu-pulasitiki, omwe amagwiritsidwa ntchito kwambiri mu zingwe zamagetsi, zingwe zolumikizirana, ndi zingwe zotchingira madzi zapakati ndi zochepa, zomwe zimathandiza makasitomala kukulitsa kukana kwa chinyezi cha chingwe ndi kudalirika kwa nthawi yayitali.
