Zingwe zapansi pamadzi zimagwira ntchito yofunika kwambiri pakulankhulana kwapadziko lonse, zomwe zimanyamula data yochulukirapo kudutsa nyanja zambiri. Kusankha zipangizo zoyenera pazingwezi n'kofunika kwambiri kuti zitsimikizire kukhalitsa, kugwira ntchito, ndi kudalirika m'madera ovuta a pansi pa madzi. M'nkhaniyi, tiwona zovuta zomwe zimakhudzidwa posankha zipangizo za zingwe zapansi pamadzi ndikukambirana njira zomwe zingathandize kupanga zisankho mwanzeru.
Kulimbana ndi Corrosion:
Chimodzi mwazovuta zazikulu pamapangidwe a chingwe chapansi pamadzi ndi dzimbiri. Zingwezi zimakhala ndi madzi a m'nyanja, zomwe zimatha kuwononga kwambiri nthawi. Kusankha zida zolimbana ndi dzimbiri ndizofunikira pa moyo wautali wa chingwe. Mayankho monga kugwiritsa ntchito aloyi osachita dzimbiri monga chitsulo chosapanga dzimbiri kapena zokutira mwapadera atha kupereka chitetezo chokwanira ku dzimbiri.
Mphamvu zamakina:
Zingwe za sitima zapamadzi zimafunika kupirira kupanikizika kwakukulu ndi kupsinjika kwa makina chifukwa cha mafunde a nyanja, mafunde, ndi kulemera kwa madzi. Kusankha Zida Zazingwe Zapansi Pamadzi zokhala ndi mphamvu zamakina apamwamba ndikofunikira kuti zingwe zitha kupirira mphamvuzi popanda kusokoneza kukhulupirika kwawo. Zida zamphamvu zolimba kwambiri monga ma aramid fibers ndi carbon fiber-reinforced polymers (CFRP) zimagwiritsidwa ntchito nthawi zambiri kupititsa patsogolo luso lamakina a zingwe zam'madzi.
Kutsekereza Madzi ndi Kusungunula:
Kusunga zotsekemera zoyenera komanso kutsekereza madzi ndikofunikira kuti tipewe kulowa kwa madzi ndikuteteza zigawo zamkati za chingwe. Polyethylene, polypropylene, ndi cross-linked polyethylene (XLPE) amagwiritsidwa ntchito kwambiri pomanga ndi kutsekereza zigawo zamadzi mu zingwe zapansi pamadzi. Zidazi zimapereka mphamvu zabwino kwambiri zotchinjiriza magetsi ndipo zimatha kukana kulowa kwamadzi, kuwonetsetsa kuti chingwe chikuyenda bwino komanso moyo wautali.
Flexibility ndi Bend Radius:
Zingwe zapansi pamadzi nthawi zambiri zimafunika kukhala zosinthika komanso zotha kupirira kupindika mobwerezabwereza popanda kusokoneza magwiridwe ake. Zida Zopangira Ma Cable Apansi Pamadzi okhala ndi kusinthasintha kwakukulu komanso kulimba kopindika pang'ono, monga mitundu ina ya polyurethane ndi elastomers, amagwiritsidwa ntchito nthawi zambiri kuwonetsetsa kuti zingwe zitha kuyikidwa ndikusungidwa m'malo osiyanasiyana apansi pamadzi ndikusunga kukhulupirika kwawo kwamagetsi ndi makina.
Thermal Kukhazikika:
Zingwe zapansi pamadzi zitha kukhala ndi kutentha kwakukulu m'malo apansi pamadzi. Ndikofunikira kusankha Zida za Ma Cable a Submarine okhala ndi kukhazikika kwamafuta kuti zitsimikizire kuti zingwe zitha kupirira kusintha kwa kutenthaku popanda kusokoneza magwiridwe antchito. Zipangizo za thermoplastic monga polyethylene ndi polypropylene zimapereka kukhazikika kwamafuta, kuwapangitsa kukhala zisankho zoyenera pakutchinjiriza ndi zigawo za sheathing.
Pomaliza:
Kusankha zipangizo zoyenera za zingwe zapansi pamadzi ndi njira yofunika kwambiri yomwe imaphatikizapo kuganizira zovuta zomwe zimakhala pansi pa madzi. Pothana ndi zinthu monga kukana kwa dzimbiri, mphamvu zamakina, kutsekereza madzi, kusinthasintha, komanso kukhazikika kwamafuta, opanga zingwe ndi ogwiritsa ntchito amatha kuwonetsetsa kuti zingwe zapansi panthaka zikuyenda bwino komanso kukhala ndi moyo wautali. Kumvetsetsa zovutazi ndikugwiritsa ntchito njira zoyankhulirana zoyenera ndizofunikira kuti pakhale maukonde odalirika komanso ogwira mtima padziko lonse lapansi.
