OPGW optical cable instistration structure
1. Kalafo ea elongation ea pele
Bakeng sa phekolo ea ho lelefatsa ha pele ha OPGW, mokhoa oa ho pholisa o ka sebelisoa, ke hore, karo-karolelano ea aluminium-tšepe ea OPGW e hlahlojoa, 'me bolelele ba pele bo phekoloa ka boleng ba pholileng ba terata e tšoanang kapa fatše. terata.
2. Moralo oa mehato e khahlanong le ho sisinyeha
Har'a lisebelisoa tse sebelisoang ke OPGW, sekontiri sa tsitsipano ke sa mofuta oa terata o sothehileng pele, 'me mohala oa terata o kentsoeng o na le terata e sothehileng le gasket ea rabara.Mefuta ena e 'meli ea lisebelisoa e na le matla a itseng a anti-vibration.E le ho matlafatsa bokhoni ba ho thibela ho sisinyeha, ho ka khoneha ho nahana ka ho kenya hamore e thibelang ho sisinyeha, eo ka kakaretso e baloang ho latela nako:
Ha span e le tlase kapa e lekana le 300M, kenya hamore e thibelang ho thothomela;
Ha span e le> 300M, kenya lihamore tse peli tse thibelang ho thothomela.
3. Mathata a lokelang ho eloa hloko kahong le kahong ea OPGW
Kaho le ho emisoa ha OPGW ho fapane le likhoele tse tloaelehileng tsa tšepe.Tlhokomelo e lokela ho nkoa ho thibela tšenyo e sa feleng ho qoba ho ama ts'ebetso ea optical fiber nakong e tlang, 'me e lokela ho lebisa tlhokomelo ho: OPGW torsion, micro-bending, khatello ea radial ea sebakeng seo ka ntle ho sekhechana le tšilafalo ho fiber optical.Ka hona, sethaleng sa kaho, mehato e latelang e sebetsang e lokela ho nkoa ho e rarolla:
(1) Thibela OPGW ho sotha
Kenya sesebelisoa sa counterweight le anti-twist holim'a boto le clamp e tiisang;
Amohela pulley e khethehileng ea double-groove;
Mochine oa likhohlano o nang le li-winch tse peli;
(2) Thibela le ho fokotsa microbending le khatello ea maikutlo ea OPGW
Ha ho li-angles tse matla tse lumelloang (bonyane ba ho kobeha radius ke 500mm);bophara ba cable ea OPGW ha ea lokela ho ba tlase ho 1500mm;
Bophara ba pulley bo lokela ho ba makhetlo a fetang 25 bophara ba OPGW, ka kakaretso e se ka tlase ho 500mm;karolo e ka hare ea pulley e lokela ho ba le lesela la nylon kapa rabara ho thibela ho senya bokaholimo ba OPGW;
Mehala e loketseng ea ho hula le lisebelisoa tsa ho lefa;
Hlalosa boholo ba bolelele ba coil ea OPGW hore e be 6000M ho thibela palo ea makhetlo ao pulley e fetang;
Lekhalo la ho potoloha ha mela ea tefo e tsoelang pele e lekanyelitsoe ho ≤30 °.Karolong ea tsitsipano ea ho lefa, tataiso ea OPGW ka mor'a sekhutlo e lokela ho ba sebopeho sa "C";
(3) Taolo ea tsitsipano ea ho lefa:
Amohela tefo ea hydraulic tension le terekere e nang le sesebelisoa sa ho lokolla tsitsipano;
Fokotsa lebelo la ho lefa ≤ 0.5 m / s;
(4) Thibela tšilafalo ea fiber
Kaho le ho hlongoa ha OPGW, tlhokomelo e lokela ho lefshoa ho kenyelletsa lipheletsong;
Qetellong, re lokela ho hopotsa motho e mong le e mong hore pele OPGW e fihla setšeng, pele ho ts'oaroa, ka mor'a ho phethoa ha erection le optical fiber connection le ho phethoa ha mohaho oohle oa mohala, teko ea ho amoheloa ha fiber ea OPGW e lokela ho etsoa. setšeng ka nako.
