1. Waya yeOPGW Fiber Composite Ground
Zvigadzirwa OPGW Dzinobatanidza mabasa ewaya yekumisa pasi uye kutaurirana kwemaziso, uye dzinonyanya kushandiswa pakutaurirana kwemasisitimu matsva ekutumira magetsi ane simba repamusoro e35 KV zvichikwira, uye dzinogona kushandiswawo kutsiva waya dzepasi dziripo dzemasisitimu ekare ekutumira magetsi ane simba repamusoro, kuwedzera kutaurirana kwemaziso uye kuita mapfupi emagetsi uye kudzivirira mheni.
Hunhu hwechimiro chezvigadzirwa OPGW: chiyuniti chesimbi isina ngura che optical fiber uye waya yemhangura yakaputirwa nearuminiyamu, waya yealuminium yakarukwa uye waya dzetambo; chiyuniti chesimbi isina ngura che optical fiber chiri pakati kana mukati mechikamu chakarukwa.
2. NZIRA YEKUSHANDISA TAMBO YEMAHARA Inozvitsigira
MASS (Metal Aerial Self-Supporting) itambo yakafanana neOPGW (Open Point Ground Wire) ine core ine layer imwe chete. Kunze kwekunge zvataurwa neimwe nzira, waya yesimbi yakasungirirwa inowanzogadzirwa nesimbi yakabatidzwa, zvichikonzera chimiro chiri nyore uye mutengo wakaderera. MASS chigadzirwa chinovhara musiyano uripo pakati peOPGW neADSS (Advanced Optical Fiber Support). Kana ikashandiswa setambo ye optical inozvimiririra, zvinhu zvikuru zvinofungwa nezvazvo isimba nekudzika, pamwe nekubviswa kwemhepo kubva kuma conductor/waya dziri pedyo nevhu. Kusiyana neOPGW, haidi kutariswa kwe short-circuit current uye kupisa, OPPC, insulation, current-carrying capacity, uye impedance, uye ADSS, haidi kutariswa kwesimba remunda panzvimbo yekuisa. Basa rewaya yesimbi yekunze nderekuchengetedza nekudzivirira fiber ye optical. Kana paine simba rakafanana rekutyoka, kunyangwe MASS ichirema kupfuura ADSS, dhayamita yayo yekunze inenge 1/4 diki pane yeADSS core tube uye inenge 1/3 diki pane yeADSS yakasungirirwa. Kune dhayamita yakafanana, simba rekutyoka uye kushushikana kunobvumirwa kweADSS zvakaderera zvikuru pane zveMASS.
