Isishwankathelo seMathiriyeli yeCable yokuThintela amanzi kunye noLwakhiwo

Izinto zeCable zokuvala amanzi

Izinto zokuthintela amanzi zinokwahlulwa ngokubanzi zibe ngamacandelo amabini: ukuthintela amanzi asebenzayo kunye nokuthintela amanzi. Ukuvala amanzi okusebenzayo kusebenzisa iimpawu zokufunxa amanzi kunye nokudumba kwezinto ezisebenzayo. Xa i-sheath okanye i-joint yonakele, ezi zixhobo zanda xa zidibene namanzi, zinciphisa ukungena kwayo ngaphakathi kwentambo. Izinto ezinjalo zibandakanyaamanzi afunxa ijeli eyandisayo, itheyiphu yokuthintela amanzi, umgubo wokuvala amanzi,umsonto wokuvala amanzi, kunye nentambo yokuthintela amanzi. Ukuthintela amanzi angenasiphelo, kwelinye icala, isebenzisa izinto ze-hydrophobic ukuvala amanzi ngaphandle kwentambo xa isheath yonakalisiwe. Imizekelo yezinto zokuthintela amanzi yipetroleum-filled paste, hot melt adhesive, kunye neheat-expanding paste.

I. Izinto zokuThintela zaManzi eziPassive

Ukuzaliswa kwezixhobo zokuvalela amanzi, ezifana nepetroleum paste, kwiintambo yayiyeyona ndlela iphambili yokuvala amanzi kwiintambo zombane zakwangoko. Le ndlela ithintela ngokufanelekileyo amanzi ukuba angangeni kwintambo kodwa ineziphene zilandelayo:

1.Yandisa kakhulu ubunzima bekhebula;

2.Ibangela ukunciphisa ukusebenza kwentambo yokuqhuba;

3.I-petroleum paste ingcolisa kakhulu i-cable joints, yenza ukucoca kube nzima;

I-4.Inkqubo yokuzaliswa okupheleleyo kunzima ukuyilawula, kwaye ukuzaliswa okungaphelelanga kunokubangela ukungasebenzi kakuhle kokuthintela amanzi.

II. Izinto ezisebenzayo zokuvala amanzi

Okwangoku, izinto ezisebenzayo zokuthintela amanzi ezisetyenziswa kwiintambo ziyi-tape yokuthintela amanzi, umgubo wokuthintela amanzi, intambo yokuthintela amanzi, kunye nentambo yokuthintela amanzi. Xa kuthelekiswa ne-petroleum paste, izinto ezisebenzayo zokuthintela amanzi zinezi mpawu zilandelayo: ukunyuswa kwamanzi aphezulu kunye nezinga eliphezulu lokuvuvukala. Ziyakwazi ukufunxa amanzi ngokukhawuleza kwaye zidumbe ngokukhawuleza ukwenza into efana nejeli ethintela ukungena kwamanzi, ngaloo ndlela iqinisekisa ukhuseleko lokukhusela intambo. Ukongeza, izinto ezisebenzayo zokuvala amanzi zikhaphukhaphu, zicocekile, kwaye kulula ukuzifaka kunye nokuzihlanganisa. Nangona kunjalo, bakwanazo ezinye iingxaki:

I-1.I-powder yokuthintela amanzi kunzima ukuyidibanisa ngokulinganayo;

I-2.I-tape yokuthintela amanzi okanye umsonto unokunyusa ububanzi obungaphandle, ukuphazamisa ukutshatyalaliswa kobushushu, ukukhawuleza ukuguga kwe-thermal ye-cable, kunye nokunciphisa umthamo wokuhambisa intambo;

3.Izinto ezisebenzayo zokuvala amanzi zibiza kakhulu.

Uhlalutyo loThintelo lwaManzi: Okwangoku, eyona ndlela iphambili e-China yokuthintela amanzi ekungeneni kumaleko wokugquma kweentambo kukunyusa umaleko wokungangeni manzi. Nangona kunjalo, ukufezekisa ukuvalwa kwamanzi okubanzi kwiintambo, akufuneki sicinge kuphela ukungena kwamanzi e-radial kodwa kwakhona sithintele ngokufanelekileyo ukusasazwa kwamanzi okude xa ingena kwintambo.

I-Polyethylene (I-Inner Sheath) I-Water Isolation Layer: Ukukhupha i-polyethylene yokuvimbela amanzi, ngokudibanisa ne-cushion layer ye-cushion (efana ne-tape yokuthintela amanzi), inokuhlangabezana neemfuno zokuvalwa kwamanzi okude kunye nokukhuselwa komswakama kwiintambo ezifakwe kwiindawo ezinomswakama ophakathi. Uluhlu lwe-polyethylene lokuthintela amanzi kulula ukwenza kwaye aludingi izixhobo ezongezelelweyo.

I-Plastiki Coated Aluminium Tape Polyethylene Bonded Waterproof Isolation Layer: Ukuba iikheyibhile zifakwe emanzini okanye kwiindawo ezifumeme kakhulu, amandla okuthintela amanzi e-radial of polyethylene isolation layers anokwanela. Kwiintambo ezifuna ukusebenza kwe-radial ephezulu yokuthintela amanzi, ngoku kuqhelekile ukusonga umaleko we-aluminiyam-yeplastiki yeteyiphu edibeneyo ejikeleze umbindi wentambo. Eli tywina lingamakhulu okanye namawaka amaxesha amaninzi axhathisa amanzi kune-polyethylene ecocekileyo. Ngethuba nje i-seam ye-tape edibeneyo iboshwe ngokupheleleyo kwaye itywinwe, ukungena kwamanzi kuphantse kungenakwenzeka. I-aluminiyam-iplastiki ye-tape edibeneyo idinga i-longitudinal wrapping and bonding process, ebandakanya utyalo-mali olongezelelweyo kunye nokuguqulwa kwezixhobo.

Kwinkqubo yobunjineli, ukufezekisa ukuvalelwa kwamanzi okude kuyinkimbinkimbi kunokuthintela amanzi e-radial. Iindlela ezahlukeneyo, ezinjengokutshintsha isakhiwo se-conductor kwi-design-tight-pressed design, zisetyenzisiwe, kodwa iziphumo ziye zancinci ngenxa yokuba kusekho izikhewu kwi-conductor ecinezelekileyo evumela ukuba amanzi asasazeke ngokusebenzisa i-capillary action. Ukufezekisa ukuvinjelwa kwamanzi okude okwenyani, kuyimfuneko ukuzalisa izikhewu kwi-conductor edibeneyo kunye nezinto zokuthintela amanzi. La manqanaba mabini alandelayo emilinganiselo kunye nezakhiwo zingasetyenziselwa ukufezekisa ukuvalwa kwamanzi okude kwiintambo:

1.Ukusetyenziswa kwee-conductor zokuvala amanzi. Yongeza intambo yokuthintela amanzi, umgubo wokuvala amanzi, umsonto ovalela amanzi, okanye usonge iteyiphu yokuthintela amanzi ujikeleze umqhubi ocinezelweyo.

2.Ukusetyenziswa kwee-cores zokuthintela amanzi. Ngethuba lenkqubo yokuvelisa ikhebula, gcwalisa i-core kunye nentambo yokuthintela amanzi, intambo, okanye ubophe i-core nge-semi-conductive okanye i-insulating tape yokuthintela amanzi.

Okwangoku, umngeni obalulekileyo ekuvinjweni kwamanzi okuhlala ixesha elide ulele kwii-conductor zokuthintela amanzi-indlela yokuzalisa izinto ezithintela amanzi phakathi kwabaqhubi kunye nokuba zeziphi izinto ezithintela amanzi ezisetyenziselwa ukuhlala zigxininise kuphando.

Ⅲ. Ukuqukumbela

Itekhnoloji yokuthintela amanzi eradial ikakhulu isebenzisa iileya zokuvala zokuthintela amanzi ezisongelwe kwi-insulation layer, kunye ne-cushion efunxa ukufuma eyongezwe ngaphandle. Kwiintambo ze-voltage eziphakathi, i-aluminiyam-iplastiki ye-composite tape isetyenziswa ngokuqhelekileyo, ngelixa iintambo eziphezulu ze-voltage ngokuqhelekileyo zisebenzisa ilothe, i-aluminiyam, okanye intsimbi yokutywina iibhatyi zentsimbi.

I-teknoloji yokuthintela amanzi e-Longitudinal ngokuyinhloko igxininise ekuzaliseni izikhewu phakathi kweentambo ze-conductive kunye nezixhobo zokuthintela amanzi ukuthintela ukusasazwa kwamanzi ecaleni kwengundoqo. Ukususela kuphuhliso lwangoku lwezobuchwepheshe, ukuzaliswa kwepowder yokuthintela amanzi kulungelelaniso olusebenzayo longitudinal amanzi okuthintela.

Ukufezekisa iintambo ezingangeni manzi ngokuqinisekileyo kuya kuchaphazela ukutshatyalaliswa kobushushu bentambo kunye nokusebenza komqhubi, ngoko ke kubalulekile ukukhetha okanye ukuyila ulwakhiwo olufanelekileyo lwentambo yokuthintela amanzi ngokusekelwe kwiimfuno zobunjineli.
