Mu kapangidwe katsopano katsopanozosagwira motozingwe,cross-linked polyethylene (XLPE) insulatedzingwe zimagwiritsidwa ntchito kwambiri. Amawonetsa magwiridwe antchito abwino kwambiri amagetsi, zida zamakina, komanso kulimba kwa chilengedwe. Zodziwika ndi kutentha kwakukulu kwa ntchito, mphamvu zazikulu zotumizira, kuyika kosalephereka, ndi kukhazikitsa ndi kukonza bwino, zimayimira njira yachitukuko ya zingwe zatsopano.
1. Chingwe Conductor Design
Kapangidwe ka Kondakitala ndi Makhalidwe: Kapangidwe ka kondakitala kamatengera mtundu wachiwiri wopangidwa ndi kondakitala wowoneka ngati fan, pogwiritsa ntchito (1 + 6 + 12 + 18 + 24) mawonekedwe okhazikika. Pazingwe zokhazikika, gawo lapakati limapangidwa ndi waya umodzi, gawo lachiwiri lili ndi mawaya asanu ndi limodzi, ndipo magawo oyandikana nawo amasiyana ndi mawaya asanu ndi limodzi. Mbali yakunjayo ndi ya kumanzere, pamene zigawo zina zoyandikana nazo zimakhala zomangika kumbali ina. Mawayawa ndi ozungulira komanso a mainchesi ofanana, kuonetsetsa kuti pamakhala bata munjira iyi. Kapangidwe kakang'ono: Kupyolera mu kuphatikizika, kondakitala pamwamba pake amakhala wosalala, kupewa kuchulukana kwa magetsi. Panthawi imodzimodziyo, imalepheretsa zipangizo zogwiritsira ntchito semi-conductive kuti zilowe m'kati mwa waya panthawi ya kutsekemera kwa extrusion, kuteteza bwino kulowa kwa chinyezi ndikuwonetsetsa kuti kusinthasintha kwina. Makondakitala otsekeka amakhala ndi kusinthasintha kwabwino, kudalirika, komanso mphamvu zambiri.
2. Cable Insulation LayerKupanga
Ntchito ya insulation layer ndikuwonetsetsa kuti chingwe chimagwira ntchito yamagetsi ndikuletsa kuyenda kwamagetsi motsatira kondakitala kuti asatulukire kunja. An extrusion kapangidwe ntchito, ndiZithunzi za XLPEosankhidwa kutchinjiriza. XLPE imapereka magwiridwe antchito apamwamba kwambiri poyerekeza ndi polyethylene, yokhala ndi zida zabwino kwambiri zotchinjiriza zamagetsi, zodziwika ndi ma dielectric constants (ε) ndi low dielectric loss tangent (tgδ). Ndiwofunika kwambiri wotchingira ma frequency high-frequency. Voliyumu yake yokana mphamvu komanso mphamvu yakuwonongeka kwamunda imakhalabe yosasinthika ngakhale patatha masiku asanu ndi awiri akumizidwa m'madzi. Chifukwa chake, amagwiritsidwa ntchito kwambiri pakutchinjiriza chingwe. Komabe, ili ndi malo otsika osungunuka. Mukagwiritsidwa ntchito mu zingwe, zolakwika za overcurrent kapena zazifupi zingayambitse kutentha, zomwe zimapangitsa kuti polyethylene ikhale yofewa komanso yosinthika, zomwe zimapangitsa kuwonongeka kwa insulation. Kuti asunge ubwino wa polyethylene, imadutsa pamtunda, kupititsa patsogolo kutentha kwake komanso kukana kusokonezeka kwa chilengedwe, kupanga polyethylene yolumikizana ndi mtanda kukhala chinthu chabwino chotchinjiriza.
3. Chingwe Stranding ndi Kukulunga Mapangidwe
Cholinga cha chingwe chomangira ndi kukulunga ndikuteteza kutsekereza, kuonetsetsa chingwe chokhazikika, ndikupewa kutsekereza kotayirira ndi zodzaza, kuwonetsetsa kuzungulira kwa pachimake. Thelamba wotsekera woletsa motoimapereka zinthu zina zoletsa moto.
Zida Zopangira Chingwe Kumangirira ndi Kukulunga: Zomangira ndizopanda moto kwambiri.nsalu zopanda nsalulamba, wokhala ndi mphamvu zolimba komanso cholozera chocheperako chalawi chosachepera 55% oxygen index. Zodzazazo zimagwiritsa ntchito zingwe zamapepala zoletsa moto (zingwe zamchere), zomwe zimakhala zofewa, zokhala ndi index ya okosijeni yosachepera 30%. Zofunikira pakumangirira chingwe ndi kukulunga kumaphatikizapo kusankha m'lifupi bandi yokulunga molingana ndi mainchesi apakati ndi ngodya ya bandiyo, komanso kupindika kapena kukulungako. Njira yokulunga ndi yamanzere. Malamba osatentha kwambiri amafunikira malamba oletsa moto. Kukana kutentha kwa zinthu zodzaza kuyenera kufanana ndi kutentha kwa chingwe, ndipo mawonekedwe ake sayenera kuyanjana ndiInsulation sheath zinthu.Iyenera kuchotsedwa popanda kuwononga pakatikati pa insulation.
