Kwa akatswiri ogula zinthu ku B2B ndi mainjiniya amagetsi, kusankha zinthu zoyenera zotetezera nthaka ndi mphezi ndi chisankho chofunikira kwambiri. Kusankha kumeneku kumakhudza mwachindunji chitetezo cha polojekiti, kutsatira malamulo, komanso ndalama zosamalira kwa nthawi yayitali. M'zaka khumi zapitazi, waya wachitsulo wopangidwa ndi mkuwa (CCS wire) ndi ndodo zomangidwa ndi mkuwa zakhala ngati njira zina zomwe zimakonda m'malo mwa mkuwa wolimba m'mafakitale amagetsi, mauthenga apakompyuta, mphamvu zongowonjezwdwanso, ndi mapulojekiti a zomangamanga padziko lonse lapansi.

Bukuli likuthandizani kumvetsetsa ubwino waukadaulo, momwe mungagwiritsire ntchito, komanso zomwe muyenera kuganizira pankhani yopezera zinthu zofunika kuphatikizapowaya wachitsulo wokutidwa ndi mkuwa, Waya wa chingwe cha CCSndindodo zophikidwa ndi mkuwaKaya mukukonza malo atsopano ogwiritsira ntchito magetsi, kukonza netiweki ya nsanja ya telecom, kapena kupeza zipangizo za famu yamagetsi yamagetsi yamagetsi, mfundo zomwe zili pansipa zikuthandizani kupanga zisankho zodziwa bwino komanso zotsika mtengo.

Kodi Waya wa Chitsulo Chokhala ndi Mkuwa (CCS Waya) N'chiyani?

Waya wachitsulo wophimbidwa ndi mkuwa ndi chowongolera cha bimetallic chokhala ndi pakati pa chitsulo (nthawi zambiri chimakhala chotsika mpaka chapakati) chokhala ndi gawo lakunja lopangidwa ndi ma electroplated kapena clad lakunja la mkuwa woyeretsedwa kwambiri. Pakati pa chitsulocho pamapereka mphamvu yokoka komanso chithandizo cha kapangidwe kake, pomwe gawo la mkuwa—nthawi zambiri 6–40% ya malo onse odutsa—limapereka mphamvu zamagetsi.

Njira zazikulu zopangira zinthu zikuphatikizapo:

• • Kupaka Ma Electroplating: Mkuwa umayikidwa mofanana pakati pa chitsulo kudzera mu njira yamagetsi, kuonetsetsa kuti mkuwa ukukhuthala bwino komanso kuti umakhala wolimba.
• • Kuphimba (Kukulunga): Mzere wa mkuwa umakulungidwa nthawi zonse ndikulumikizidwa ndi chitsulo pakati pa chitsulo, zomwe zimapangitsa kuti mawonekedwe a bimetallic akhale opanda msoko.

Popeza mafunde amphamvu kwambiri amayenda pamwamba pa kondakitala (zotsatira za khungu), waya wa CCS umakwaniritsa ntchito yotumiza ma signal yofanana ndi waya wolimba wamkuwa wa mulifupi womwewo, pomwe umachepetsa kugwiritsa ntchito mkuwa ndi 50–70%.

Waya wa CCS Strand vs. Solid Copper: Kodi Zikufanana Bwanji?

Poyesa ma conductor a ma grounding grids, ma messenger wards, kapena ma conductor amkati a coaxial cable, ogula a B2B nthawi zambiri amayerekeza waya wa CCS strand ndi waya wolimba wamkuwa. Kuyerekeza kotsatiraku kukuwonetsa kusiyana kwakukulu:

Pa ntchito zambiri zoyika pansi, zomangira, ndi zotumizira ma signal, waya wa CCS umapereka magwiridwe antchito abwino kwambiri, kulimba, ndi mtengo. Mkuwa wolimba umakhalabe chisankho cha ntchito zomwe zimafuna mphamvu yoyendetsera bwino kwambiri (monga zida zolondola) kapena pamene ma code amalamula kuti izi zichitike.

Ndodo Zokhala ndi Mkuwa: Msana wa Machitidwe Odalirika Okhazikika

Ma electrode oyambira pansi ndi mgwirizano wofunikira pakati pa makina amagetsi ndi dziko lapansi. Amapereka njira yochepetsera kuponderezedwa kwa magetsi ndi mphezi kuti zizitha kufalikira bwino, kuteteza zida ndi antchito. Ndodo zoyambira pansi zokhala ndi mkuwa—zomwe zimadziwikanso kuti ndodo zoyambira pansi zopangidwa ndi mkuwa—ndi zina mwa ma electrode oyambira pansi omwe amagwiritsidwa ntchito kwambiri padziko lonse lapansi.

Xinchang Shibang amapanga ndodo zomangira mkuwa pogwiritsa ntchito electroplating ya 99.9% ya mkuwa woyeretsedwa wa electrolytic pa zitsulo zamtengo wapatali zopanda mpweya wambiri. Mafotokozedwe aukadaulo ofunikira ndi awa:

Ndodo zophwanyidwa ndi mkuwa ndizoyenera malo osiyanasiyana—kuyambira nthaka yokhazikika mpaka nthaka yonyowa, yamchere, kapena nthaka yogwira ntchito ndi mankhwala. Zimagwiritsidwa ntchito kwambiri mu:

• • Malo opangira magetsi ndi malo osinthira magetsi

• • Kukhazikitsa mphamvu zongowonjezedwanso (mafamu a dzuwa, ma turbine amphepo)
• • Makina amagetsi ndi zizindikiro za sitima
• • Malo opangira mafakitale ndi malo opangira mafuta
• • Kumanga maziko a nyumba zamalonda ndi nyumba zogona

Kuwotcherera kwa Exothermic: Kupanga Malumikizidwe Okhazikika, Osalimba Pansi

Ngakhale waya wachitsulo wapamwamba kwambiri wokhala ndi mkuwa ndi ndodo zomangira pansi zimakhala zogwira ntchito bwino ngati kulumikizana pakati pawo. Kuwotcherera kwa exothermic (komwe kumadziwikanso kuti thermite welding) ndiye muyezo wabwino kwambiri wopanga maubwenzi okhazikika pakati pa ma grounding conductors.

Njirayi imagwiritsa ntchito njira ya mankhwala—nthawi zambiri pakati pa ufa wa aluminiyamu ndi okusayidi wa mkuwa—kuti ipange kutentha kopitirira 1,400°C. Mkuwa wosungunuka womwe umatuluka umalowa mu nkhungu ya graphite, yozungulira ma conductors omwe akuyenera kulumikizidwa. Ikazizira, weld imapanga kulumikizana ndi:

• • Kukana kwa magetsi kofanana kapena kotsika kuposa ma conductors okha
• • Mphamvu ya makina yofanana ndi yamphamvu ya zitsulo ziwiri zolumikizidwa
• • Kukana dzimbiri bwino kwambiri, ngakhale pansi pa nthaka kapena m'nyanja.
• • Palibe chifukwa chogwiritsa ntchito magetsi akunja—ndi abwino kwambiri poyika magetsi akutali

Kuwotcherera kwa exothermic n'kofunika kwambiri polumikiza chitsulo chophimbidwa ndi mkuwa ndi mkuwa weniweni, mkuwa ndi chitsulo chophimbidwa ndi galvanized, kapena mkuwa ndi chitsulo chopopera. Ndi njira yolumikizira yomwe imakondedwa kwambiri yomwe yatchulidwa mu IEEE 80 ya machitidwe okhazikika ndipo imadziwika ndi US National Electrical Code (NEC) §250.8 ngati njira yovomerezeka yolumikizira ma bonding grounding conductors.

Momwe Mungasankhire Waya Wachitsulo Woyenera wa Copper Clad pa Ntchito Yanu
