Umgangatho weCable ye-ADSS kunye neSikhokelo seXabiso

2025-03-20

Ubuza malunga Iintambo ze-ADSS ngokugxila kumgangatho olungileyo kunye nexabiso. Makhe ndiyichaze le nto. Okokuqala, zithini iintambo ze-ADSS. Ziintambo ezizixhasayo ze-All-Dielectric ezisetyenziswa ekufakweni kwe-fiber optic ephezulu. Amanqaku aphambili apha ngumgangatho kunye nexabiso.

 

Ngoko ke, umsebenzisi mhlawumbi ufuna ukwazi ukuba yintoni eyenza intambo ye-ADSS esemgangathweni kunye nendlela amaxabiso asebenza ngayo. Ndifanele ndiqale ngokuchaza izinto ezimisela umgangatho. Oko kuya kuquka izinto ezisetyenzisiweyo, njengohlobo lweglasi kwimicu, izinto zejakethi (i-HDPE ixhaphakile), kunye nentambo ye-aramid yokuqina. Kwakhona, izinto ezinje ngamandla okutsalwa kunye nokumelana nemozulu zibalulekile.

 

Okulandelayo, izinto ezibangela amaxabiso. Ndifuna ukukhankanya ukuba ixabiso lixhomekeke kubuninzi befayibha, ubude, umlinganiselo wokutsalwa, kunye nazo naziphi na iimpawu ezongezelelweyo ezifana nokumelana neempuku. Ababoneleli banokubonelela ngezaphulelo zomthamo, ngoko mhlawumbi ungacebisa ukuba uqhagamshelane nabo ngokuthe ngqo ukuze ufumane iikowuteshini. Kwakhona, udumo lwebhrendi ludlala indima apha—iibhrendi ezidumileyo zinokubiza ngaphezulu kodwa zinikezela ngokuthembeka.

 

Emva koko, cetyiswa ababoneleli. Amagama anje ngeCorning, iPrysmian, iFujikura, iAFL, kunye neFeiboer afika engqondweni. Ezi ziinkampani ezidumileyo ezaziwa ngomgangatho. Ukubandakanya ababoneleli bamazwe ngamazwe kunye nabaseTshayina kunokuba luncedo kuba umsebenzisi usenokuba ufuna ukhetho kwiindawo ezahlukeneyo.

 

Ndifanele ndongeze neengcebiso zokuqinisekisa ixabiso lemali. Izinto ezinje ngokuqinisekisa iziqinisekiso (ISO, RoHS), ukujonga iinkcukacha zobugcisa ngokuthelekisa neemfuno zeprojekthi, ukufumana iisampulu, kunye nokuthelekisa iikowuteshini. Mhlawumbi khankanya ukubaluleka kwenkxaso emva kokuthengisa kunye newaranti.

 

Linda, umsebenzisi usenokuba ngumakhi okanye umphathi weprojekthi ofuna ukuthenga ezi ntambo. Bafuna ukulinganisela iindleko ngaphandle kokubeka emngciphekweni umgangatho. Ngoko ke ukugxininisa ulungelelwaniso phakathi komgangatho kunye nexabiso kubalulekile. Mhlawumbi ugxininise ukuba nangona iindleko zokuqala zinokuba phezulu kwiimveliso ezisemgangathweni, zonga imali ekuhambeni kwexesha ngokuqina kunye nokugcinwa okuncinci.

 

Ndifanele ndicinge nangeendleko ezifihlakeleyo ezinokubakho. Umzekelo, intambo engabizi kakhulu inokuba namandla okutsala aphantsi, nto leyo ekhokelela ekutshintsheni okanye ekusileleni rhoqo, nto leyo eyongeza kwixabiso lilonke. Ngoko ke kubalulekile ukucebisa ukuba ungachithi iinkcukacha ezibalulekileyo.

 

Kwakhona, imeko-bume yokusetyenziswa ibalulekile. Ukuba ukufakelwa kukwindawo enemozulu embi, imimoya enamandla, okanye amaqondo obushushu aphezulu, intambo kufuneka imelane nezo meko. Ngoko ke izinto ezisemgangathweni kufuneka zihambelane neemfuno zokusingqongileyo.

 

Mhlawumbi ungafaka uluhlu lwamaxabiso oluqhelekileyo, kodwa ekubeni amaxabiso etshintshatshintsha kwaye exhomekeke kwizinto ezithile, kungcono ukucebisa ukuba ufumane ikowuteshini eyenzelwe wena. Nangona kunjalo, ukunika inani eliphakathi kwe-$0.50 ne-$2 ngemitha nganye kunokunceda ekubekeni ulindelo, nangona kufuneka ndilumke kuba oku kunokwahluka kakhulu.

 

Ukubandakanya ababoneleli bamazwe ngamazwe nabaseTshayina kulungile kuba abavelisi baseTshayina abafana neFeiboer, Hengtong okanye iZTT banokubonelela ngamaxabiso akhuphisanayo, anokuba nomtsalane ukuba umsebenzisi uzimisele kakhulu kwibhajethi kodwa usafuna umgangatho othembekileyo.

 

Kwakhona, ukukhankanya ukubaluleka kodumo lomthengisi kunye nenkonzo yasemva kokuthengisa kunokukhokela umsebenzisi ukuba acinge kungekuphela nje ngemveliso kodwa nangenkxaso engasemva kwayo. Inkxaso yobugcisa ngexesha lokufakwa inokuba yinto ebalulekileyo kumntu ongenalo ulwazi lwangaphambili ngeentambo ze-ADSS.

 

Ndifanele ndihlele impendulo ngokuqala ndichaze ukuba yintoni emisela umgangatho, ndize ndilandele izinto ezibonisa amaxabiso, ndilandele iingcebiso zababoneleli, kunye neengcebiso zokufumana ixabiso elifanelekileyo. Ndigqibezela ngesiphelo esiqinisa ulungelelwaniso phakathi komgangatho kunye nokusebenza kakuhle kweendleko.

 

Kufuneka uqinisekise ukuba onke amagama obuchwephesha acacisiwe ngokucacileyo, kodwa ngaphandle kokubiza kakhulu. Umsebenzisi usenokuba sele esazi iziseko, kodwa kungcono ukuba achaze ngokucokisekileyo. Kuphephe ukusebenzisa ulwimi oluntsonkothileyo apho kunokwenzeka, okanye uluchaze ngokufutshane.

 

Jonga ukuba kukho na imigangatho yoshishino enxulumene neentambo ze-ADSS ekufuneka zikhankanyiwe, njengemigangatho ye-IEC okanye yeTelcordia. Ukuthobela le migangatho kunokuba luphawu lomgangatho.

 

Kwakhona, mhlawumbi thetha ngeendlela zokwenza ngokwezifiso. Abanye ababoneleli banikezela ngeentambo ezenzelwe iimfuno ezithile, ezinokuchaphazela ixabiso kunye nokufaneleka kweprojekthi.

 

Okokugqibela, qinisekisa ukuba icebiso liyasebenza. Umsebenzisi mhlawumbi ufuna amanyathelo afanelekileyo: indlela yokuvavanya ababoneleli, iinkcukacha ekufuneka zijongwe, indlela yokuxoxisana ngamaxabiso, njl.njl.
