Thumela i-imeyile1. Iintambo ze-OPGW ezibonakalayo zisetyenziswa kakhulu kwimigca ye-voltage ye-110KV, 220KV, 550KV, kwaye zisetyenziswa kakhulu kwimigca esandula ukwakhiwa ngenxa yezizathu ezifana nokucinywa kombane kunye nokhuseleko.
2. Imigca enevolthi ephezulu edlula i-110kv inoluhlu olukhulu (ngokubanzi ngaphezu kwe-250M).
3. Kulula ukuyilungisa, kulula ukuyisombulula ingxaki yokuwela umgca, kwaye iimpawu zayo zoomatshini zinokuhlangabezana nomgca wokuwela omkhulu;
4. Umaleko wangaphandle we-OPGW sisikhuselo sesinyithi, esingachaphazeli ukugqwala kunye nokuwohloka kombane ombane ophezulu.
5. I-OPGW kufuneka icinywe ngexesha lokwakhiwa, kwaye ukulahleka kombane kukhulu kakhulu, ngoko ke i-OPGW kufuneka isetyenziswe kwimigca esandul’ ukwakhiwa enamandla aphezulu angaphezu kwe-110kv.
Iimpawu eziphambili:
● Ububanzi bentambo encinci, ubunzima obulula, umthwalo ophantsi owongezelelweyo kwinqaba;
● Ityhubhu yentsimbi ibekwe embindini wentambo, akukho monakalo wesibini wokudinwa koomatshini.
● Ukumelana okuphantsi koxinzelelo lwecala, ukugoba kunye nokuxinana (umaleko omnye).
