Chingwe chamagetsi - Waya Wopanda Pansi Wokhala ndi Ulusi Wowala (OPGW) Wasin Fujikura
chiyambi
► OPGW kapena yotchedwa Optical Ground Waya ndi mtundu wa chingwe chokhala ndi waya wolumikizira magetsi ndi waya wolumikizira magetsi pamwamba pa waya kuti ipereke mphamvu. Imagwiritsidwa ntchito mu mizere yolumikizira magetsi ngati chingwe cha ulusi wa kuwala komanso waya wolumikizira magetsi pamwamba pa waya womwe ungapereke chitetezo ku kugunda kwa mphezi komanso kuyendetsa magetsi afupikitsa.
► OPGW imakhala ndi chubu chosapanga dzimbiri chachitsulo chosapanga dzimbiri, waya wachitsulo chophimbidwa ndi aluminiyamu, waya wa aluminiyamu wopangidwa ndi aluminiyamu. Ili ndi kapangidwe ka chubu chosapanga dzimbiri chachitsulo chapakati komanso kapangidwe ka chingwe cha waya. Tikhoza kupanga kapangidwe kake malinga ndi momwe zinthu zilili komanso zosowa za makasitomala.
Mbali
► Chida chosapanga dzimbiri cha ulusi wa kuwala cha chubu chapakati chotayirira kapena kapangidwe ka chingwe
► Waya wa aluminiyamu ndi waya wachitsulo wokhala ndi aluminiyamu
► Yokutidwa ndi mafuta oletsa kuwononga pakati pa zigawo
► OPGW imatha kuthandizira kuyika katundu wolemera komanso nthawi yayitali
► OPGW ikhoza kukwaniritsa zofunikira za waya wapansi pa makina ndi magetsi posintha kuchuluka kwa chitsulo ndi aluminiyamu.
► Zosavuta kupanga mafotokozedwe ofanana a waya wapansi womwe ulipo ukhoza kulowa m'malo mwa waya wapansi womwe ulipo.
► OPGW imapatsa Makampani Amagetsi mwayi wogwiritsa ntchito nsanja zawo pazinthu zina kupatula kutumiza magetsi. Iwo, chifukwa cha ndalama zochepa, amatha kupereka maulalo amphamvu kwambiri ku gawo la Telecom.
Katundu wa ntchito
► Chingwe cha OPGW chimayendetsedwa, kapena kuyikidwa pakati pa nsonga za ma pyloni amagetsi amphamvu kwambiri, chitsulo, matabwa, kapena mitengo ya konkire yokhala ndi zolumikizira zoyenera ndi zolumikizira. Gawo loyendetsa chingwe, pamenepa chitsulocho chimagwira ntchito yolumikiza nsanja zapafupi ndi nthaka, ndikuteteza ma kondakitala amphamvu kwambiri ku mphezi.
► OPGW ali ndi khalidwe loti palibe mphamvu ya induction yamagetsi apamwamba pa deta yomwe ikutumizidwa kudzera mu Ulusi. Chifukwa chake khalidwe ili la Ulusi limagwiritsidwa ntchito potumiza deta kudzera mu mizere yotumizira yamagetsi amphamvu kwambiri.
► Ulusi wa kuwala mkati mwa chingwe ungagwiritsidwe ntchito potumiza deta mwachangu kwambiri. Kampani yamagetsi ingagwiritse ntchito chingwe cha fiber optics pa SCADA yake, chitetezo ndi njira yowongolera chingwe chotumizira mauthenga, VOIP, ndi zina zolumikizirana. Zikatero, amatha kusunga ndalama zoyika mawaya ena achitsulo omwe amagwiritsidwa ntchito ngati mawaya apansi kapena otchingira ku zingwe zawo. Angathenso kubwereka kapena kugulitsa kwa anthu ena kuti akhale ngati kulumikizana kwa fiber optic mwachangu pakati pa mizinda, ndi maukonde ena.
