OPGW intambo yokubonaimigca kufuneka ithwale imithwalo eyahlukeneyo phambi nasemva kokwakhiwa, kwaye kufuneka ijongane nemekobume yendalo eqatha efana nobushushu obuphezulu ehlotyeni, ukubetha kombane, kunye nomkhenkce nekhephu ebusika, kwaye kufuneka bajongane nemisinga eqhubekayo kunye nokufutshane- imisinga yesekethe ebangelwa yimigca yesigaba samandla.Indawo yokusebenza enzima apho ubushushu bukhuphuka ngenxa yempembelelo ye-thermal, ngoko ke, kubaluleke kakhulu ukukhetha i-optical cable ye-OPGW efanelekileyo. 
(1) Ukukhethwa kwezixhobo ezikrwada kunye nezincedisayo: khetha iimveliso ezidumileyo kwihlabathi njenge-fiber optical main, intlama yefiber yokuthintela amanzi, umcu wentsimbi, i-aluminium clad steel wire (AS), i-aluminium alloy wire (AA), njl. qinisekisa ezona zalathisi zoMgangatho zingcono.
(2) Iimpawu zoomatshini ze-OPGW intambo yokukhanya: Intambo ephothiweyo ngaphandle kombindi we-OPGW intambo yokukhanya iqulunqwe kakhulu yi-AA wire (i-aluminium alloy wire) kunye ne-AS wire (i-aluminium clad steel wire) ukuqinisekisa amandla aphezulu, ukuhanjiswa okuphezulu, kunye ne-anti. -ukwenziwa komhlwa.Okugqwesileyo, isizukulwana esitsha se-stainless steel tyhubhu yeemveliso ze-OPGW optical cable zizodwa phakathi kweemveliso ezifanayo, kwaye ziyahlangabezana neemfuno ezingxamisekileyo zelizwe lam i-500KV, 220KV kunye namanye amanqanaba ombane ahlukeneyo olwakhiwo lonxibelelwano lwentambo optical fiber.Ngokulungelelanisa umlinganiselo we-aluminium / wentsimbi kunye neenkcukacha zocingo, kukho ngaphezu kwe-100 OPGW izakhiwo zekhebula kubasebenzisi ukuba bakhethe.
Kwityhubhu edibeneyo kunye ne-tube ephakathi yeemveliso ze-OPGW optical cable, i-diameter yangaphandle yentambo ye-optical iyafana kwiiparitha zobugcisa.Ngenxa yenani elihlukeneyo lemigca ye-AS kunye nemigca ye-AA, iimpawu zomatshini kunye nombane we-OPGW iintambo ezibonakalayo zikwahluke.Ukuze utshatise uxinzelelo lwe-OPGW kunye nomhlaba kwelinye icala, kuyafuneka ukuba iipropathi zabo zoomatshini, kubandakanya amandla okuqina (RTS), imodyuli elastiki, i-coefficient yokwandiswa komgca, ubunzima, kunye nedayamitha yangaphandle, kufuneka isondele kakhulu. kangangoko kunokwenzeka.
(3) Uxinzelelo oluphezulu lomsebenzi (MAT): Xa i-OPGW intambo ye-optical isetyenziswa njengocingo oluphantsi lomgca wokuhambisa amandla, ukukhethwa koxinzelelo olukhulu lokusebenza kufana nocingo oluqhelekileyo lomhlaba, olulungele ukulungiswa koxinzelelo lwe-sag. ngezihlandlo ezahlukeneyo, kwaye uyanelisa isikhokelo seziko kunye nocingo olusezantsi lwepitch Phakathi kweemfuno zomgama.Ngaphantsi kwesi sizathu, ukunyanzeliswa kufuneka kukhululeke kangangoko kunokwenzeka ukuze kuqinisekiswe ukuba i-fiber optical ayigxininisi phantsi komthwalo.
(4) Umyinge woxinzelelo lwemihla ngemihla (EDS): Ukumiselwa kweli xabiso kuchaphazela ngokuthe ngqo ukusebenza okukhuselekileyo kwexesha elide lekhebula le-optical cable.Emva kokwamkela amanyathelo okulwa nokunyakaza ngokuhambelana nenkcazo yokuyila umgca, uxinzelelo lwemihla ngemihla yokusebenza komqhubi ngu-15-25% RTS, kwaye ngokuqhelekileyo kucetyiswa ukuba kuthathe Ixabiso li-18%.
(5) Umthamo wangoku wesiphaluka esifutshane (I2t): Umthamo okhoyo wesiphaluka omfutshane wentambo ye-OPGW uhambelana ne-current (I) ehamba ngentambo ye-OPGW xa i-single-phase ground fault iyenzeka kwinkqubo, isenzo sokukhusela. ixesha (t), ubushushu bokuqala kunye nobona bushushu buphezulu obuvumelekileyo.Eli xabiso lihambelana ngokusondeleyo neendleko zesakhiwo se-OPGW, kwaye isalathisi se-shunt yesayensi kunye nezoqoqosho emva kokucima i-fiber optical kunye ne-2 iingcingo zomhlaba kufuneka ziqwalaselwe.
(6) Ukulawulwa kobude obude be-fiber optical kwintambo ye-OPGW ebonakalayo: ngokuqhelekileyo i-OPGW eboshiweyo ifumana ubude obungaphezulu besibini be-fiber optical ngokujija ubude obude be-fiber optical kwi-tube yensimbi engenasici kunye nokujija intambo ukuya. qinisekisa ukuba i-fiber optical ayichaphazeli intambo ye-OPGW phantsi koxinzelelo olukhulu lokusebenza.Amandla;esona salathisi sokulawula ubude obugqithisileyo bentambo yokukhanya ye-OPGW, kunye nokwandisa uyilo ngovavanyo loxinzelelo loxinzelelo ngokudibanisa neemeko zokusebenza.
