Unolwazi olungakanani ngeentambo zombane ezisetyenziswa rhoqo? (Icandelo lesi-2)

1. Intambo yoMhlaba yeFiber Composite ye-OPGW

Iimveliso I-OPGW Zidibanisa imisebenzi yocingo olusezantsi kunye nonxibelelwano lwe-optical, kwaye zisetyenziswa kakhulu kwimigca yonxibelelwano yeenkqubo ezintsha zothumelo lwe-high-voltage oluphezulu ezingama-35 KV nangaphezulu, kwaye zinokusetyenziselwa ukutshintsha iingcingo zomhlaba ezikhoyo zeenkqubo ezindala zothumelo lwe-high-voltage oluphezulu, zongeze iingcingo zonxibelelwano lwe-optical kwaye ziqhube imisinga yesekethe emfutshane kwaye zibonelele ngokhuseleko lombane.

Iimpawu zesakhiwo seemveliso I-OPGW: iyunithi yefayibha yentsimbi engagqwaliyo kunye nocingo lobhedu olugqunywe yialuminiyam, ucingo lwe-aluminium alloy olugoqiweyo kunye neentambo; iyunithi yefayibha yentsimbi engagqwaliyo ikwindawo esembindini okanye engaphakathi yomaleko ogoqiweyo.

2. Intambo ye-optical yesinyithi exhasayo eyi-MASS

I-MASS (i-Metal Aerial Self-Supporting) yintambo efana ne-OPGW (i-Open Point Ground Wire) ene-core enye ebambekileyo. Ngaphandle kokuba kuchazwe ngenye indlela, i-wire metal stranded idla ngokwenziwa ngentsimbi egqunyiweyo, nto leyo ebangela isakhiwo esilula kunye nexabiso eliphantsi. I-MASS yimveliso evala umsantsa phakathi kwe-OPGW kunye ne-ADSS (i-Advanced Optical Fiber Support). Xa isetyenziswa njenge-optical cable ezixhasayo, izinto eziphambili ekufuneka ziqwalaselwe ngamandla nokuwa, kunye nokususwa kokhuseleko kwii-conductors/wires zomhlaba ezikufutshane kunye nomhlaba. Ngokungafaniyo ne-OPGW, ayifuni kuqwalaselwa umbane we-short-circuit kunye nomthamo wobushushu, i-OPPC, i-insulation, umthamo wokuthwala umbane, kunye ne-impedance, kunye ne-ADSS, ayifuni kuqwalaselwa umbane wentsimi kwindawo yokufakela. Umsebenzi we-outer metal wire kukulungiselela nokukhusela i-optical fiber kuphela. Kwimeko yamandla okuqhekeka afanayo, nangona i-MASS inzima kune-ADSS, ububanzi bayo bangaphandle buncinci malunga ne-1/4 kunobo be-ADSS core tube kwaye buncinci malunga ne-1/3 kunobo be-ADSS eneeleya. Kwi-diameter efanayo, amandla okuphuka kunye noxinzelelo oluvumelekileyo lwe-ADSS ziphantsi kakhulu kunezo ze-MASS.
