I-OPGW (Optical Ground Wire) luhlobo lwentambo yocingo esetyenziswa kushishino lonxibelelwano ukuze idlulise idatha ngeteknoloji yefiber optic, ngelixa ikwabonelela ngokuhanjiswa kwamandla ombane kwiintambo zamandla ombane aphezulu.Iintambo ze-OPGW ziyilwe ngombhobho osembindini okanye umbindi, apho kubekwa khona umaleko omnye okanye ngaphezulu wentsimbi okanye iingcingo ze-aluminiyam, kunye nomaleko wangaphandle wemicu optical.Ukwakhiwa kweentambo ze-OPGW kuyahluka ngokuxhomekeke kwisicelo kunye neemfuno ezithile zenkqubo yentambo yombane.
Kukho iintlobo ezintathu ezisisiseko ze-OPGW yezakhiwo zeentambo:
Umbhobho ophakathi: Olu hlobo lwekhebula luqukethe ityhubhu ephakathi, apho kukho iingcingo zetsimbi ezibekwe okanye i-aluminium alloy wires.Iifiber ze-optical emva koko zibekwe kwi-tube.Olu luyilo luvumela ukuguquguquka okukhulu kwaye lunikeze indawo eninzi yeefibers optical.
Layer Stranding: Olu hlobo lwentambo lunemigangatho emininzi yentsimbi okanye iingcingo ze-aluminiyam ezidityanisiweyo.Iifiber ze-optical zibekwe kwii-interstices phakathi kweengcingo.Olu luyilo lubonelela ngamandla ngakumbi kwaye lufanelekile ngakumbi kwizicelo zoxinzelelo oluphezulu.
Unitube: Olu hlobo lwekhebula lunombhobho owodwa apho zombini intsimbi okanye iingcingo ze-aluminium kunye neentambo ze-optical zibekwe.Olu luyilo lubonelela ngentambo edibeneyo ekulula ukuyifaka.
Iintambo ze-OPGW nazo zinokuhlelwa ngokusekelwe kwinani lefiber, elisusela kwi-12 ukuya kuma-288 eentsinga.Ukhetho lobalo lwefayibha luxhomekeke kwisicelo esithile kunye neemfuno zomthamo wenkqubo yentambo yombane.
