Iintambo ezingenamanzi zibhekisela kuhlobo lwekhebula apho izixhobo ze-sheath ezingenamanzi kunye noyilo zamkelwa kwisakhiwo sekhebula ukukhusela amanzi ukuba angene ngaphakathi kwesakhiwo sentambo. Injongo yalo ephambili kukuqinisekisa ukusebenza okukhuselekileyo kunye nokuzinzileyo kwexesha elide lekhebula kwindawo emanzi, phantsi komhlaba okanye ngaphantsi kwamanzi kunye nezinye iindawo ezinomswakama ophezulu, kunye nokuthintela iingxaki ezifana nokuchithwa kombane kunye nokuguga kwe-insulation okubangelwa ukungena kwamanzi. Ngokweendlela zabo ezahlukeneyo zokukhusela, zinokuthi zihlulwe kwiintambo ezingenamanzi ezithintela ukungena kwamanzi ngokuthembela kwisakhiwo ngokwawo, kunye neentambo zokuthintela amanzi ezikhusela amanzi ukuba asasazeke ngokuphendula kwezinto eziphathekayo.
Intshayelelo kwi-JHS Type Waterproof Cable
Uhlobo lwe-JHS lwentambo engangeni manzi yintambo eqhelekileyo yerabha eneshethi engenamanzi. Zombini umaleko wayo wokugquma kunye nesheath zenziwe ngerabha, ebonisa ukuguquguquka okugqwesileyo kunye nokuqina kwamanzi. Isetyenziswa ngokubanzi kwiindawo ezifana nonikezelo lwamandla ompompo ophantsi kwamanzi, ukusebenza phantsi komhlaba, ukwakhiwa kwamanzi angaphantsi kwamanzi, kunye ne-drainage yesikhululo samandla, kwaye ifanelekile ixesha elide okanye intshukumo ephindaphindiweyo emanzini. Olu hlobo lwekhebula ludla ngokuthatha isiseko se-three-core kwaye lufanelekile kwiimeko ezininzi zokudibanisa impompo yamanzi. Njengoko ukubonakala kwayo kufana neentambo eziqhelekileyo ze-rubber-sheathed, xa ukhetha uhlobo, kubaluleke kakhulu ukuba uqinisekise ukuba unesakhiwo sangaphakathi esingangeni manzi okanye uyilo lwe-sheath yesinyithi ukuqinisekisa ukuba ihlangabezana neemfuno zangempela zendawo yokusetyenziswa.
Ubume kunye neendlela zokukhusela iintambo ezingenamanzi
Uyilo lolwakhiwo lweentambo ezingangeni manzi zihlala zihluka ngokweemeko zokusetyenziswa kunye namanqanaba ombane. Kwiintambo ezingundoqo ezingenamanzi,i-semi-conductive tape yokuthintela amanziokanye eqhelekileyoiteyiphu yokuthintela amanziisoloko isongelwe kwi-insulation shielding layer, kunye nezinto ezongezelelweyo zokuthintela amanzi zingasetwa ngaphandle kwe-metal shielding layer. Ngexesha elifanayo, i-powder yokuthintela amanzi okanye iintambo zokuzalisa amanzi zidibeneyo ukuze kuphuculwe ukusebenza kokutywinwa ngokubanzi. Isixhobo se-sheath ubukhulu becala i-polyethylene ephezulu (i-HDPE) okanye irabha ekhethekileyo enokuthintela amanzi, esetyenziselwa ukunyusa umthamo we-radial wokungangeni kwamanzi.
Kwiintambo zombane ophakathi okanye ophakathi kunye nophezulu, ukomeleza ukusebenza kokungangeni manzi, iteyiphu ye-aluminium egqunywe ngeplastiki isoloko isongelwe ngobude ngaphakathi komgangatho wangaphakathi okanye i-sheath, ngelixa i-sheath ye-HDPE ikhutshelwa kumaleko angaphandle ukwenza ulwakhiwo oluhlanganisiweyo olungangeni manzi. Kubaipolyethylene edityaniswe ngomnqamlezo (XLPE)iintambo ezigqunyiweyo ze-110kV nangaphezulu kwamabanga, iishethi zetsimbi ezifana ne-aluminiyam ecinezelwe ngokushushu, ilothe ecinezelwe ngokushushu, i-aluminiyam edityanisiweyo edityanisiweyo, okanye iishethi zetsimbi ezitsalwa ngokubanda zihlala zisetyenziselwa ukubonelela ngezakhono ezingcono zokukhusela i-radial.
Indlela yokukhusela iintambo ezingenamanzi: i-longitudinal kunye ne-radial waterproofing
Iindlela zokukhusela amanzi kwiintambo ezingenamanzi zingahlulwa zibe yi-longitudinal waterproofing kunye ne-radial waterproofing. Ukungangeni kwamanzi ixesha elide kuxhomekeke kwizinto ezithintela amanzi, ezifana nomgubo wokuthintela amanzi, umsonto wokuthintela amanzi, kunye ne-tape yokuthintela amanzi. Emva kokuba amanzi engena, baya kwandisa ngokukhawuleza ukwenza umaleko wokuzihlukanisa ngokwasemzimbeni, ukuthintela ngokufanelekileyo amanzi ukuba asasazeke kunye nobude bekhebula. Ukuthintela amanzi kwiradial ikakhulu kuthintela amanzi ukuba angangeni kwintambo ephuma ngaphandle ngokusebenzisa izixhobo zesheath okanye iisheath zetsimbi. Iintambo eziphakamileyo ezingenamanzi zivame ukudibanisa ukusetyenziswa kweendlela ezimbini zokufumana ukhuseleko olubanzi lwamanzi.
Umahluko phakathi kweentambo ezingangeni manzi kunye neentambo zokuvala amanzi
Nangona iinjongo zezi zimbini zifana, kukho umahluko ocacileyo kwimigaqo yolwakhiwo kunye neemeko zokusetyenziswa. Inqaku eliphambili leentambo ezingenamanzi kukuthintela amanzi ukuba angene ngaphakathi kweentambo. Ulwakhiwo lwabo ubukhulu becala lwamkela iishethi zetsimbi okanye izixhobo ezixineneyo ezixineneyo, kugxininiswa ekungangeni kwamanzi kwiradial. Zilungele indawo ezihlala ixesha elide eziphantsi kwamanzi ezifana neempompo ezingaphantsi kwamanzi, izixhobo eziphantsi komhlaba, kunye neetonela ezimanzi. Iintambo zokuvala amanzi, kwelinye icala, zijolise ngakumbi kwindlela yokuthintela ukusasazwa kwamanzi emva kokuba engenile. Ubukhulu becala basebenzisa izinto ezithintela amanzi ezandisayo xa zidibene namanzi, ezinje ngomgubo wokuthintela amanzi, intambo yokuthintela amanzi, kunye neteyiphu yokuthintela amanzi, ukufezekisa iziphumo zokuthintela amanzi kwilongitudinal. Ngokuqhelekileyo zisetyenziswa kwiimeko zesicelo ezifana neentambo zonxibelelwano, iintambo zombane, kunye neentambo zokukhanya. Isakhiwo esipheleleyo seentambo ezingenamanzi ziyinkimbinkimbi kwaye iindleko ziphezulu, ngelixa iintambo zokuthintela amanzi zinesakhiwo esiguquguqukayo kunye neendleko ezilawulekayo, kwaye zifanelekile kwiindawo ezininzi zokubeka.
Intshayelelo yeeFom zoLwakhiwo lokuValwa kwamanzi (yeeCybhuli zokuvala amanzi)
Izakhiwo zokuthintela amanzi zingahlelwa zibe yi-conductor yokuthintela amanzi kunye nezakhiwo ezingundoqo zokuthintela amanzi ngokwendawo yangaphakathi yekhebula. Isakhiwo sokuthintela amanzi sabaqhubi sibandakanya ukongeza i-powder-blocking powder okanye intambo yokuthintela amanzi ngexesha lenkqubo yokuguqula abaqhubi ukuba benze i-longitudinal water barrier layer. Kufanelekile kwiimeko apho kuyimfuneko ukukhusela ukusabalalisa ngaphakathi kwabaqhubi. Isakhiwo sokuthintela amanzi kwi-core cable yongeza i-tape yokuthintela amanzi ngaphakathi kwentambo yentambo. Xa i-sheath yonakalisiwe kwaye amanzi angena, ikhula ngokukhawuleza kwaye ivimbele iziteshi ze-cable core, ukukhusela ukusasazeka okuqhubekayo. Kwizakhiwo ezininzi ezisisiseko, kucetyiswa ukuba kuthathelwe iiplani ezizimeleyo zokuthintela amanzi kwisiseko ngasinye ngokulandelanayo ukwenza iindawo ezingaboniyo ezithintela amanzi ezibangelwa zizikhewu ezinkulu kunye neemilo ezingaqhelekanga zeentambo zentambo, ngaloo ndlela ziphucula ukuthembeka okupheleleyo kwamanzi.

Ukuqukumbela
Iingcingo ezingenamanzi kunye neentambo zokuvala amanzi nganye zineempawu zayo zobugcisa kunye nemida ecacileyo yesicelo. Kubunjineli bokwenyani, esona skimu sifanelekileyo sobume besakhiwo esingenamanzi kufuneka sivavanywe ngokupheleleyo kwaye sikhethwe ngokusekelwe kwindawo yokubeka, ubomi benkonzo, inqanaba lombane kunye neemfuno zokusebenza koomatshini. Ngexesha elifanayo, ngelixa ugxininisa ukusebenza kweentambo, ingqwalasela kufuneka ihlawulwe kumgangatho kunye nokuhambelana kwezinto eziluhlaza ezingenamanzi.
ILIZWE ELINYEinikezelwe ekuboneleleni abavelisi bekhebula kunye nezisombululo ezipheleleyo zamanzi kunye nokuthintela amanzi, kubandakanywa i-tape yokuthintela amanzi, i-semi-conductive water-blocking tape, intambo yokuthintela amanzi, i-HDPE, i-polyethylene edibeneyo (i-XLPE), njl. Asinikezeli kuphela izinto ezikumgangatho ophezulu, kodwa sikwanalo neqela lobuchwephesha lokuxhasa abathengi ekuyileni nasekulungiseleleni izakhiwo ezahlukeneyo zokungena manzi, ukunceda ukuqinisa ukuthembeka nokusebenza kweentambo.
