Tataiso ea Boleng ba Cable ea ADSS le Theko

2025-03-2020

U botsa ka Likhoele tsa ADSS ka ho tsepamisa maikutlo boleng bo botle le theko. E re ke hlalose sena hantle. Taba ea pele, hore na likhoele tsa ADSS ke eng. Ke likhoele tse Itšehetsang tsa All-Dielectric tse sebelisoang lits'ebetsong tsa fiber optic tse holim'a hlooho. Lintlha tsa bohlokoa mona ke boleng le theko.

Kahoo, mohlomong mosebelisi o batla ho tseba hore na ke eng e etsang thapo ea ADSS ea boleng bo botle le hore na litheko li sebetsa joang. Ke lokela ho qala ka ho hlalosa lintlha tse khethollang boleng. Seo se tla kenyelletsa thepa e sebelisoang, joalo ka mofuta oa khalase ka har'a likhoele, thepa ea baki (HDPE e tloaelehile), le khoele ea aramid bakeng sa matla. Hape, lintho tse kang matla a ho tsitlella le ho hanyetsa boemo ba leholimo lia bohlokoa.

E latelang, lintlha tsa litheko. Ke hloka ho bolela hore theko e itšetlehile ka palo ea faeba, bolelele, tekanyo ea ho tsitlella, le likarolo life kapa life tse ling tse kang ho hanyetsa litoeba. Bafepedi ba ka 'na ba fana ka litheolelo tsa bongata, kahoo mohlomong ba ka fana ka tlhahiso ea ho ikopanya le bona ka kotloloho bakeng sa litheko. Hape, botumo ba lets'oao bo bapala karolo mona - lihlahisoa tse hlomphehang li ka bitsa chelete e ngata empa li fana ka ts'epo.

Ebe ho kgothaletswa bafepedi. Mabitso a kang Corning, Prysmian, Fujikura, AFL, le Feiboer a tla kelellong. Tsena ke dikhamphani tse tsebahalang ka boleng. Ho kenyeletsa bafepedi ba matjhaba le ba China ho ka thusa kaha mosebedisi a ka nna a batla dikgetho dibakeng tse fapaneng.

Hape ke lokela ho eketsa malebela a ho netefatsa boleng ba chelete. Lintho tse kang ho netefatsa mangolo a netefatso (ISO, RoHS), ho hlahloba lintlha tsa tekheniki khahlanong le litlhoko tsa projeke, ho fumana disampole, le ho bapisa litheko. Mohlomong u bolele bohlokoa ba tšehetso ea kamora thekiso le waranti.

Ema hanyane, mosebelisi e ka ba rakonteraka kapa molaodi wa projeke ya batlang ho reka dikheibole tsena. Ba batla ho leka-lekanya ditjeo ntle le ho beha boleng kotsing. Kahoo ho totobatsa tekano pakeng tsa boleng le theko ke ntho ya bohlokwa. Mohlomong totobatsa hore le hoja ditjeo tsa pele di ka ba hodimo bakeng sa dihlahiswa tsa boleng, di boloka tjhelete ha nako e ntse e ya ka ho tshwarella le tlhokomelo e tlase.

Hape ke lokela ho nahana ka litšenyehelo tse ka bang teng tse patehileng. Mohlala, thapo e theko e tlase e ka ba le matla a tlase a ho thaepa, e leng se lebisang ho lintlheng tse ling khafetsa kapa ho hloleha, e leng se eketsang litšenyehelo tsohle. Kahoo ho bohlokoa ho eletsa hore u se ke ua hlokomoloha lintlha tsa bohlokoa.

Hape, tikoloho ea ts'ebeliso ea bohlokoa. Haeba ho kenngoa ho le sebakeng se nang le boemo ba leholimo bo bobe, meea e matla, kapa mocheso o feteletseng, thapo e hloka ho mamella maemo ao. Kahoo lintlha tsa boleng li lokela ho lumellana le litlhoko tsa tikoloho.

Mohlomong ho kenyeletsoa le mefuta e fapaneng ea litheko, empa kaha litheko lia fetoha 'me li itšetlehile ka lintlha tse itseng, ho molemo ho eletsa ho fumana khotheishene e ikhethileng. Leha ho le joalo, ho fana ka palo ea boleng bo holimo joalo ka $0.50 ho isa ho $2 ka mithara ho ka thusa ho beha litebello, leha ho hlokahala hore ke be hlokolosi kaha sena se ka fapana haholo.

Ho kenyelletsa bafepedi ba matjhaba le ba China ho hotle hobane bahlahisi ba China ba kang Feiboer, Hengtong kapa ZTT ba ka fana ka ditheko tse hlwahlwa, e leng se ka bang monate haeba mosebedisi a na le kelohloko ya tjhelete empa a ntse a batla boleng bo ka tshepahalang.

Hape, ho bua ka bohlokwa ba botumo ba mofani le tshebeletso ya kamora thekiso ho ka tataisa mosebedisi ho nahana eseng feela ka sehlahiswa empa le ka tshehetso e ka morao ho sona. Tshehetso ya botekgeniki nakong ya ho kenya e ka ba ya bohlokwa ho motho ya se nang boiphihlelo ba pele ka dikheibole tsa ADSS.

Ke lokela ho hlophisa karabo ka ho hlalosa pele hore na ke eng e etsang hore boleng bo be bo itseng, ebe lintlha tsa litheko, li lateloe ke likhothaletso tsa mofani oa thepa, le malebela a ho fumana boleng bo botle ka ho fetisisa. Ke qetella ka sephetho se matlafatsang tekano lipakeng tsa boleng le katleho ea litšenyehelo.

Ho hlokahala ho etsa bonnete ba hore mantsoe ohle a tekheniki a hlalositsoe ka ho hlaka, empa ntle le ho bua haholo. Mosebelisi a ka 'na a se a ntse a tseba lintho tsa motheo, empa ho molemo ho ba le puo e hlakileng. Qoba puo e sa tloaelehang moo ho khonehang, kapa u e hlalose ka bokhutšoanyane.

Hlahloba hore na ho na le maemo afe kapa afe a indasteri a amanang le likhoele tsa ADSS a lokelang ho boleloa, joalo ka maemo a IEC kapa Telcordia. Ho latela tsena e ka ba letšoao la boleng.

Hape, mohlomong re ka bua ka dikgetho tsa ho iketsetsa. Bafepedi ba bang ba fana ka dikheibole tse etseditsweng ditlhoko tse itseng, tse ka amang theko le ho tshwaneleha ha projeke.

Qetellong, etsa bonnete ba hore keletso e ea sebetsa. Ho ka etsahala hore mosebelisi a batle mehato e ka sebelisoang: mokhoa oa ho lekola bafepedi, lintlha tseo a lokelang ho li hlahloba, mokhoa oa ho buisana ka litheko, jj.

Ha o nahana kaLikhoele tsa ADSS (All-Dielectric Self-Supporting), ho leka-lekanyabolenglethekoe hloka ho utloisisa lintlha tsa bohlokoa tse susumetsang ka bobeli. Mona ke tataiso e hlophisitsoeng ho u thusa ho etsa qeto e nang le tsebo:

Kamehla netefatsa dintlha tse hlalositsweng mabapi le ditlhoko tsa hao tsa tikoloho (mohlala, dibaka tsa leqhoa/moya). Bakeng sa ho tshepahala ha nako e telele, tsetela ho matshwao a tsebahalang bakeng sa ho kenngwa tshebetsong ha dibaka tse kotsi haholo.
