Waya Wopanda Pansi wa OPGW Wowala

Waya wamagetsi wopangidwa pansi (OPGW) ndi chingwe chogwira ntchito ziwiri. Chapangidwa kuti chilowe m'malo mwa mawaya achikhalidwe osasinthika/oteteza/opanda mphamvu pamizere yotumizira pamwamba ndi phindu lowonjezera la kukhala ndi ulusi wowala womwe ungagwiritsidwe ntchito pazinthu zolumikizirana. OPGW iyenera kukhala yokhoza kupirira kupsinjika kwa makina komwe kumayikidwa pazingwe zapamwamba chifukwa cha zinthu zachilengedwe monga mphepo ndi ayezi. OPGW iyeneranso kukhala yokhoza kuthana ndi zolakwika zamagetsi pa chingwe chotumizira popereka njira yopita pansi popanda kuwononga ulusi wowala womwe uli mkati mwa chingwecho.

Kapangidwe ka chingwe cha OPGW kamapangidwa ndi chitoliro cha fiber optic (chokhala ndi mayunitsi angapo kutengera kuchuluka kwa ulusi) chomwe chili mu chitoliro cholimba cha aluminiyamu chotsekedwa bwino chokhala ndi waya umodzi kapena ingapo wachitsulo ndi/kapena alloy. Kuyika kuli kofanana kwambiri ndi njira yomwe imagwiritsidwa ntchito poyika ma conductor, ngakhale kuti muyenera kusamala kuti mugwiritse ntchito kukula koyenera kwa sheave kapena pulley kuti musawononge kapena kuphwanya chingwecho. Pambuyo poyika, chingwecho chikakonzeka kulumikizidwa, mawayawo amadulidwa kuti awonetse chitoliro chapakati cha aluminiyamu chomwe chingadulidwe mosavuta ndi chida chodulira chitoliro. Mayunitsi ang'onoang'ono okhala ndi mitundu yosiyanasiyana ndi omwe amagwiritsidwa ntchito kwambiri chifukwa amapangitsa kukonzekera kwa bokosi la splice kukhala kosavuta.
