Ukwazi kangakanani ngamakhebula kagesi asetshenziswa kakhulu? (Ingxenye 2)

1. Ikhebula Elingaphansi Le-OPGW Fiber Composite

Imikhiqizo I-OPGW Zihlanganisa imisebenzi yentambo yokumisa kanye nokuxhumana kwe-optical, futhi zisetshenziselwa kakhulu imigqa yokuxhumana yezinhlelo ezintsha zokudlulisa i-high-voltage eziphezulu ezingama-35 KV nangaphezulu, futhi zingasetshenziswa futhi ukufaka esikhundleni sezintambo ezikhona zomhlabathi zezinhlelo zokudlulisa i-high-voltage ezindala eziphezulu, zandise imigqa yokuxhumana kwe-optical futhi ziqhube imisinga ye-short-circuit futhi zinikeze isivikelo sombani.

Izici zesakhiwo semikhiqizo I-OPGW: iyunithi ye-fiber optical tube yensimbi engagqwali kanye nentambo yethusi embozwe nge-aluminium, intambo ye-aluminium alloy elukiwe kanye nezintambo; iyunithi ye-fiber optical tube yensimbi engagqwali itholakala phakathi noma ungqimba lwangaphakathi lwengqimba elukiwe.

2. Intambo ye-optical yensimbi ezisekelayo

I-MASS (Metal Aerial Self-Supporting) iyikhebula elifana ne-OPGW (Open Point Ground Wire) elinomgogodla ogobekile onesendlalelo esisodwa. Ngaphandle kokuthi kuchazwe ngenye indlela, ucingo lwensimbi olugobekile luvame ukwenziwa ngensimbi ehlanganisiwe, okuholela esakhiweni esilula kanye nezindleko eziphansi. I-MASS umkhiqizo ohlanganisa igebe phakathi kwe-OPGW ne-ADSS (Advanced Optical Fiber Support). Uma isetshenziswa njengekhebula elibonakalayo elizisekelayo, izinto eziyinhloko okufanele zicatshangelwe amandla nokugoba, kanye nokususwa kokuphepha okuvela kubaqhubi bomhlaba/izintambo eziseduze nomhlabathi. Ngokungafani ne-OPGW, ayidingi ukucatshangelwa kwamandla kagesi afushane kanye nomthamo wokushisa, i-OPPC, ukufudumeza, umthamo wokuthwala ugesi, kanye ne-impedance, kanye ne-ADSS, ayidingi ukucatshangelwa kwamandla ensimu endaweni yokufaka. Umsebenzi wocingo lwensimbi lwangaphandle kuphela ukwamukela nokuvikela i-fiber ekhanyayo. Endabeni yamandla okuphuka afanayo, yize i-MASS inzima kune-ADSS, ububanzi bayo bangaphandle bucishe bube yi-1/4 kunobethubhu eliyinhloko le-ADSS futhi bucishe bube yi-1/3 kunobe-ADSS enezingqimba. Ngobubanzi obufanayo, amandla okuphuka kanye nokucindezeleka okuvunyelwe kwe-ADSS kuphansi kakhulu kunaleyo ye-MASS.
