Thumela i-imeyileI-1.OPGW iintambo ze-optical cable zisetyenziswa kakhulu kwi-110KV, 220KV, 550KV imigca yezinga lombane, kwaye isetyenziswa kakhulu kwimigca esanda kwakhiwa ngenxa yezinto ezifana nokuhamba kombane kunye nokhuseleko.
2. Imigca enamandla ombane aphezulu adlula i-110kv inoluhlu olukhulu (ngokubanzi lungaphezu kwe-250M).
3. Kulula ukuyigcina, kulula ukuyicombulula ingxaki yokuwela umgca, kunye neempawu zayo zomatshini zinokudibana nomgca wokunqumla okukhulu;
4. Umaleko wangaphandle we-OPGW sisikrweqe sesinyithi, esingachaphazeli i-voltage ephezulu ye-corrosion yombane kunye nokuthotywa.
5. I-OPGW mayicinywe umbane ngethuba lolwakhiwo, kwaye ilahleko yombane inkulu kakhulu, ngoko ke i-OPGW kufuneka isetyenziswe kwiintambo ezisanda kwakhiwa ezinombane ophezulu ngaphezu kwe-110kv.
Iimpawu eziphambili:
● Ubukhulu bekhebula elincinci, ubunzima obulula, umthwalo ophantsi owongezelelweyo kwinqaba;
● Umbhobho wentsimbi ubeka embindini wentambo, akukho monakalo wesibini wokudinwa komatshini.
● Ukuchasana okuphantsi koxinzelelo lwecala, ukunyanzeliswa kunye nokuqina (uluhlu olulodwa).
