Waya womangidwa kale amagwiritsidwa ntchito polumikiza zolumikizira za kondakitala wamagetsi apamwamba ndi chingwe cholumikizira chingwe, kuyimitsidwa ndi kulumikizana. Waya womangidwa kale adawonekera koyamba ku United States m'ma 1940 ndi 1950s. Choyambiriracho chinali chitetezo cha mawaya ozungulira kuti pakhale kupsinjika kwa waya wopanda kanthu komanso malo a dzimbiri lamagetsi ndi kuyatsa kwa arc. Pambuyo pazaka zachitukuko, zida zokhotakhota zisanachitike zakhala zikugwiritsidwa ntchito kwambiri pakutumiza ndi kugawa mphamvu, kulumikizana kwa fiber, njanji yamagetsi, ma TV, zomangamanga, ulimi ndi madera ena.
Waya wachitsulo wa aluminiyamu amagwiritsidwa ntchito kwambiri mu 10 kV yogawa maukonde a waya wamba, ali ndi maubwino angapo amphamvu yolimba kwambiri, chitetezo chabwino chachitetezo cha mphezi, mtengo wotsika, chimagwiritsidwa ntchito kwambiri m'malo olumikizirana matauni ndi mizere yamagetsi yakumidzi. . Komabe, pamene chingwe chachitsulo chachitsulo cha aluminiyumu chachitsulo chawonongeka ndi mphamvu yakunja kapena nyengo yoipa, zimakhala zosavuta kukhala ndi vuto lalifupi la dera. Pamene chigawo chachifupi chosakanikirana chikuchitika, waya udzathyoledwa. Zinthu zotere zikapezeka, chithandizo choyenera chokonza mawaya chiyenera kuperekedwa munthawi yake kuti tipewe kupitiliza kwa zingwe zotayirira zomwe zimabweretsa kuchepetsedwa kwa mawotchi ndi magetsi a waya.
Waya wotsogola ndi wopangidwa kuchokera ku waya angapo ozungulira omwe amawongoleredwa. Malinga ndi kukula kwa gawo la waya, waya wa helix wokhala ndi m'mimba mwake wamkati umazunguliridwa motsatira njira ya helix kuti apange tubular. Waya womangidwa kale ndi wozungulira wokulungidwa kunja kwa waya. Pansi pa kugwedezeka kwa waya, zozungulira zimazungulira kupanga mphamvu yolumikizira waya. Kulimba kwa waya kumakulirakulira, kulimba kozungulira kumakhala kolimba komanso mphamvu yogwira imakulirakulira. Waya wokonzedweratu wokonzedweratu amagwiritsidwa ntchito kwambiri mu 35 kV ndi pamwamba pa mizere, koma sagwiritsidwa ntchito pang'onopang'ono mu mizere ya 10 kV, ndipo angagwiritsidwe ntchito pagawo la mzere ndi 7% kapena kucheperapo chingwe chosweka ndipo kuwonongeka sikuli kwakukulu, ndipo sungathe kufika pakulimbitsa. Kupanikizika kowongoleredwa kolumikizira kapamwamba ndi mtundu watsopano wazinthu zamawaya zopindika m'zaka zaposachedwa. Amagwiritsidwa ntchito ngati chida cholumikizira. Ikhoza kugwiritsidwa ntchito m'malo mwa ochiritsira achepetsa kuthamanga kulumikiza chitoliro ndi kuthamanga chitoliro, angagwiritsidwe ntchito kulumikiza zotayidwa stranded waya, zotayidwa aloyi stranded waya, zitsulo pachimake zitsulo zotayidwa stranded waya ndi mawaya ena, kukwaniritsa mphamvu yake yoyambirira makina ndi ntchito magetsi.
