Ikhwalithi Yekhebula le-ADSS kanye Nomhlahlandlela Wentengo

2025-03-20

Ubuza mayelana Amakhebula e-ADSS ngokugxila kwikhwalithi enhle kanye nentengo. Ake ngikuchaze lokhu. Okokuqala, ukuthi ziyini izintambo ze-ADSS. Ziyizintambo ezizisekelayo ze-All-Dielectric ezisetshenziswa ekufakweni kwe-fiber optic ephezulu. Amaphuzu abalulekile lapha yikhwalithi kanye nentengo.

 

Ngakho-ke, umsebenzisi cishe ufuna ukwazi ukuthi yini eyenza ikhebula le-ADSS elisezingeni elihle nokuthi amanani asebenza kanjani. Kufanele ngiqale ngokuchaza izici ezinquma ikhwalithi. Lokho kuzofaka phakathi izinto ezisetshenziswayo, njengohlobo lwengilazi kumafayibha, impahla yejakethi (i-HDPE ivamile), kanye nentambo ye-aramid yokuqina. Futhi, izinto ezifana namandla okudonseka kanye nokumelana nesimo sezulu zibalulekile.

 

Okulandelayo, izici zamanani. Ngidinga ukusho ukuthi intengo incike ekubalweni kwefayibha, ubude, isilinganiso sokudonseka, kanye nanoma yiziphi izici ezengeziwe njengokumelana namagundane. Abahlinzeki bangase banikeze izaphulelo zomthamo, ngakho-ke mhlawumbe basikisele ukuxhumana nabo ngqo ukuze uthole izingcaphuno. Futhi, idumela lomkhiqizo lidlala indima lapha—imikhiqizo ehloniphekile ingabiza kakhulu kodwa inikeza ukuthembeka.

 

Bese kuba abahlinzeki abanconywayo. Amagama afana neCorning, iPrysmian, iFujikura, i-AFL, kanye neFeiboer ayafika engqondweni. Lezi yizinkampani ezisunguliwe ezaziwa ngekhwalithi. Ukufaka abahlinzeki bamazwe ngamazwe kanye nabaseShayina kungaba usizo njengoba umsebenzisi angase afune izinketho ezifundeni ezahlukene.

 

Kufanele futhi ngengeze amathiphu okuqinisekisa inani lemali. Izinto ezifana nokuqinisekisa izitifiketi (i-ISO, i-RoHS), ukuhlola imininingwane yobuchwepheshe ngokuhambisana nezidingo zephrojekthi, ukuthola amasampula, nokuqhathanisa izingcaphuno. Mhlawumbe khuluma ngokubaluleka kokusekelwa ngemuva kokuthengisa kanye newaranti.

 

Linda, umsebenzisi angaba ngusonkontileka noma umphathi wephrojekthi ofuna ukuthenga lezi zintambo. Bafuna ukulinganisela izindleko ngaphandle kokubeka engcupheni ikhwalithi. Ngakho-ke ukugcizelela ibhalansi phakathi kwekhwalithi nentengo kubalulekile. Mhlawumbe qokomisa ukuthi yize izindleko zokuqala zingase zibe phezulu emikhiqizweni esezingeni eliphezulu, zonga imali ngokuhamba kwesikhathi ngokuqina nokugcinwa okuphansi.

 

Kufanele futhi ngicabangele izindleko ezingase zifihleke. Isibonelo, ikhebula elishibhile lingase libe namandla aphansi okudonseka, okuholela ekushintsheni noma ekuhlulekeni okuvamile, okwengeza ezindlekweni eziphelele. Ngakho-ke kubalulekile ukweluleka ukuthi unganciphisi imininingwane ebalulekile.

 

Futhi, indawo yokusetshenziswa ibalulekile. Uma ukufakwa kusendaweni enesimo sezulu esibi, imimoya enamandla, noma amazinga okushisa aphezulu, ikhebula lidinga ukumelana nalezo zimo. Ngakho-ke izici zekhwalithi kufanele zivumelane nezidingo zemvelo.

 

Mhlawumbe faka uhla lwamanani olulinganiselwe, kodwa njengoba amanani eshintshashintsha futhi encike ezintweni ezithile, kungcono ukweluleka ukuthola isilinganiso esenziwe ngokwezifiso. Kodwa-ke, ukunikeza inani eliphakathi kuka-$0.50 no-$2 ngemitha kungasiza ekubekeni okulindelwe, yize kudingeka ngiqaphele njengoba lokhu kungahluka kakhulu.

 

Ukufaka abahlinzeki bamazwe ngamazwe nabaseShayina kuhle ngoba abakhiqizi baseShayina abafana noFeiboer, Hengtong noma i-ZTT bangase banikeze amanani ancintisanayo, okungaba kuhle uma umsebenzisi eqaphela isabelomali kodwa esafuna ikhwalithi ethembekile.

 

Futhi, ukukhuluma ngokubaluleka kwedumela lomhlinzeki kanye nensizakalo yangemva kokuthengisa kungasiza umsebenzisi ukuthi angacabangi nje ngomkhiqizo kodwa nokusekelwa kwawo. Ukusekelwa kobuchwepheshe ngesikhathi sokufakwa kungabaluleka kumuntu ongenalo ulwazi lwangaphambilini ngezintambo ze-ADSS.

 

Kufanele ngihlele impendulo ngokuchaza kuqala ukuthi yini enquma ikhwalithi, bese kuba izici zamanani, kulandelwe izincomo zabahlinzeki, kanye namathiphu okuthola inani elihle kakhulu. Ngiphetha ngesiphetho esiqinisa ibhalansi phakathi kwekhwalithi nokusebenza kahle kwezindleko.

 

Kudingeka uqinisekise ukuthi wonke amagama obuchwepheshe achazwe ngokucacile, kodwa ngaphandle kokukhuluma kakhulu. Umsebenzisi kungenzeka ukuthi usevele uyazi izisekelo, kodwa kungcono ukucacisa. Gwema ukusebenzisa amagama anzima lapho kungenzeka khona, noma uwachaze kafushane.

 

Hlola ukuthi zikhona yini izindinganiso zemboni eziphathelene namakhebula e-ADSS okufanele zikhulunywe ngazo, njengezindinganiso ze-IEC noma ze-Telcordia. Ukuhambisana nalezi kungaba uphawu lwekhwalithi.

 

Futhi, mhlawumbe ungathinti izinketho zokwenza ngokwezifiso. Abanye abahlinzeki banikeza izintambo ezenzelwe izidingo ezithile, ezingathinta intengo kanye nokufaneleka kwephrojekthi.

 

Okokugcina, qiniseka ukuthi iseluleko siyasebenza. Umsebenzisi cishe ufuna izinyathelo ezisebenzisekayo: indlela yokuhlola abahlinzeki, ukuthi yiziphi izici okufanele azihlole, indlela yokuxoxisana ngamanani, njll.
