Ngethuba lofakelo kunye nokusetyenziswa kwekhebula, lonakaliswe nguxinzelelo lomatshini, okanye ikhebula lisetyenziselwa ixesha elide kwindawo enomswakama kunye namanzi, okuya kubangela ukuba amanzi angaphandle angene ngokuthe ngcembe kwikhebula. Ngaphantsi kwesenzo sentsimi yombane, amathuba okuvelisa umthi wamanzi kwindawo yokugquma intambo iya kwanda. Umthi wamanzi owenziwe yi-electrolysis uya kuqhekeza i-insulation, ukunciphisa ukusebenza kwe-insulation jikelele yekhebula, kunye nokuchaphazela ubomi benkonzo yentambo. Ngoko ke, ukusetyenziswa kweentambo ezingangeni manzi kubalulekile.
Ikheyibhuli ingangeni manzi ikakhulu iqwalasela ukuntywila kwamanzi ecaleni kwendlela yentambo yomqhubi kunye necala elijikelezayo lentambo edlula kwisingxobo sentambo. Ngoko ke, i-radial waterproof and longitudinal water-blocking structure ingasetyenziswa.
1.Ikhebula yeradial engenamanzi
Injongo ephambili yokukhutshwa kwamanzi e-radial kukuthintela ukuhamba kwamanzi angaphandle okujikelezayo kwikhebula ngexesha lokusetyenziswa. Ulwakhiwo olungangeni manzi lunolu khetho lulandelayo.
1.1 Polyethylene sheath engenamanzi
I-polyethylene sheath engenamanzi isebenza kuphela kwiimfuno eziqhelekileyo zokungena kwamanzi. Kwiintambo ezintywiliselwe emanzini ixesha elide, ukusebenza kokungangeni manzi kweentambo ze-polyethylene ezifakwe emanzini zifuna ukuphuculwa.
1.2 Isingxobo sentsimbi singangeni manzi
Ubume beradial obungangeni manzi kwiintambo zombane ophantsi kunye nombane olinganisiweyo we-0.6kV/1kV nangaphezulu ubonwa ngokubanzi ngaphaya komaleko ongaphandle okhuselayo kunye nokusonga kwangaphakathi kwebhanti ehlangeneyo ye-aluminiyam-yeplastiki ephindwe kabini. Iintambo zamandla ombane aphakathi kunye ne-3.6kV/6kV yamandla ombane kunye nangaphezulu zi-radial waterproof phantsi kwesenzo esidibeneyo sebhanti edibeneyo ye-aluminium-plastiki kunye ne-semi-conductive resistance hose. Iintambo zombane eziphakamileyo ezinamaqondo ombane aphezulu zinokungangeni manzi ngeeshethi zetsimbi ezinje ngeeshethi zelothe okanye iishethi zealuminiyam.
Isingxobo esibanzi sokungangeni manzi sisebenza ikakhulu kumsele wentambo, ongcwatywe ngokuthe ngqo amanzi angaphantsi komhlaba kunye nezinye iindawo.
2. Ikhebhula ngokuthe nkqo ingangeni manzi
Ukuxhatshazwa kwamanzi okude kunokuthathwa njengento yokwenza i-cable conductor kunye ne-insulation ibe nefuthe lokumelana namanzi. Xa umaleko ongaphandle okhuselayo wentambo wonakaliswe ngenxa yamandla angaphandle, ukufuma okujikelezileyo okanye ukufuma kuya kungena ngokuthe nkqo ecaleni komqhubi wekhebula kunye nolwalathiso lwe-insulation. Ukuze ugweme umswakama okanye umonakalo womswakama kwintambo, sinokusebenzisa ezi ndlela zilandelayo ukukhusela intambo.
(1)Iteyiphu yokuthintela amanzi
Indawo yokwandiswa kwamanzi echasene namanzi yongezwa phakathi kwe-core wire core kunye ne-aluminium-plastic composite strip. I-tape yokuvala i-Water ihlanganiswe kwi-core wire core okanye i-cable core, kunye nesantya sokugubungela kunye ne-25%. I-tape yokuthintela amanzi iyanda xa idibana namanzi, okwandisa ukuqina phakathi kweTape yokuthintela amanzi kunye ne-cable sheath, ukuze kufezekiswe umphumo wokuthintela amanzi.
(2)Iteyiphu yokuthintela amanzi e-semi-conductive
I-Semi-conductive tape yokuthintela amanzi isetyenziswa ngokubanzi kwintambo yombane ophakathi, ngokusonga i-Semi-conductive tape yokuthintela amanzi kwi-metal shielding layer, ukufezekisa injongo yokumelana namanzi e-longitudinal yentambo. Nangona umphumo wokuthintela amanzi wentambo uphuculwe, ububanzi bangaphandle bekhebula buyanda emva kokuba intambo ihlanganiswe kwi-tape yokuthintela amanzi.
(3)Ukuzaliswa kokuthintela amanzi
Izinto zokuzaliswa kokuthintela amanzi ziqhelekileumsonto wokuvala amanzi(intambo) kunye nomgubo wokuvala amanzi. I-powder yokuthintela amanzi isetyenziselwa kakhulu ukuvala amanzi phakathi kwee-coodor cores eziphothiweyo. Xa i-powder yokuthintela amanzi inzima ukuyifaka kwi-conductor monofilament, i-adhesive yamanzi efanelekileyo ingasetyenziselwa ngaphandle kwe-conductor monofilament, kwaye i-powder-blocking powder ingagqunywa ngaphandle komqhubi. Umsonto ovala amanzi (intambo) udla ngokusetyenziswa ukuvala izikhewu phakathi koxinzelelo oluphakathi lweentambo ezingundoqo ezintathu.
3 Ulwakhiwo oluqhelekileyo lokumelana namanzi ekhebula
Ngokommandla ohlukeneyo wokusetyenziswa kunye neemfuno, i-cable water resistance structure ibandakanya i-radial waterproof structure, i-longitudinal (kubandakanywa ne-radial) isakhiwo sokumelana namanzi kunye ne-round-round-round resistance structure. Isakhiwo sokuthintela amanzi kwikhebula le-voltage ephakathi kwezintathu ezingundoqo zithathwa njengomzekelo.
3.1 Ulwakhiwo lweRadial olungangeni manzi lwentambo yombane yamandla aphakathi angundoqo amathathu
I-Radial yokungangeni manzi kwentambo yombane yamandla amathathu engundoqo ephakathi ngokubanzi ithatha iteyiphu yokuthintela amanzi eSemi-conductive kunye neplastiki enamacala amabini agqunywe ngeteyiphu yealuminiyam ukuphumeza umsebenzi wokuxhathisa amanzi. Ulwakhiwo lwalo ngokubanzi lu: umqhubi, umaleko okhuselayo we-conductor, ukugquma, umaleko okhuselayo, umaleko okhuselayo wesinyithi (iteyiphu yobhedu okanye ucingo lobhedu), ukuzaliswa okuqhelekileyo, iteyiphu yokuthintela amanzi, iplasitiki enamacala amabini agqunywe nge-aluminium tape longitudinal ipakethe, sheath yangaphandle. .
3.2 Ulwakhiwo loxhathiso lwamanzi olunezimbo ezintathu ezingundoqo eziphakathi kwamandla ombane
Intambo yamandla ombane aphakathi amathathu engundoqo ikwasebenzisa i-semi-conductive tape yokuthintela amanzi kunye neplastiki enamacala amabini agqunywe ngeteyiphu yealuminiyam ukuphumeza umsebenzi wokuxhathisa amanzi. Ukongeza, intambo yokuthintela amanzi isetyenziselwa ukuzalisa isithuba phakathi kweentambo ezintathu eziphambili. Ulwakhiwo lwalo ngokubanzi lu: i-conductor, i-conductor shielding layer, i-insulation, i-insulation shielding layer, i-semi-conductive tape yokuthintela amanzi, i-metal shielding layer (iteyiphu yobhedu okanye ucingo lobhedu), ukugcwaliswa kwentambo yokuvala amanzi, i-semi-conductive tape yokuthintela amanzi, i-sheath yangaphandle.
3.3 I-Three-core ye-voltage ye-voltage ephakathi ejikeleza yonke isakhiwo sokuxhathisa amanzi
I-cable yesakhiwo sokuthintela amanzi esijikelezayo sidinga ukuba i-conductor nayo ibe nefuthe lokuthintela amanzi, kwaye idibaniswe neemfuno ze-radial waterproof kunye ne-longitudinal water blocking, ukufezekisa ukujikeleza kwamanzi okujikelezayo. Ulwakhiwo lwalo ngokubanzi lu: i-conductor yokuthintela amanzi, i-conductor shielding layer, i-insulation, i-insulation shielding layer, i-semi-conductive tape yokuthintela amanzi, i-metal shielding layer (iteyiphu yobhedu okanye ucingo lobhedu), intambo yokuthintela amanzi, iteyiphu yokuthintela amanzi. , iplastiki enamacala amabini agqunywe nge-aluminiyam tape iphakheji longitudinal, sheath yangaphandle.
Intambo yokuthintela amanzi engundoqo emithathu ingaphuculwa ibe yizithinteli ezintathu zentambo yokuthintela amanzi (ezifana ne-aerial-core insulated cable structure). Oko kukuthi, i-core cable nganye iqala ukuveliswa ngokuhambelana ne-single-core water-blocking cable structure, kwaye ke iintambo ezintathu ezihlukeneyo zixutywe ngekhebula ukuze zithathe indawo yentambo yokuthintela amanzi. Ngale ndlela, kungekuphela nje ukuphucula ukuchasana kwamanzi kwentambo, kodwa kwakhona ukubonelela ngokulula kokulungiswa kwentambo kunye nokufakwa kamva kunye nokubeka.
4.Izilumkiso zokwenza izixhumi zentambo zokuthintela amanzi
(1) Khetha izinto ezifanelekileyo ezidibeneyo ngokweenkcukacha kunye neemodeli zentambo ukuze uqinisekise umgangatho wentambo yentambo.
(2) Musa ukukhetha iintsuku zemvula xa usenza iintambo zentambo zokuthintela amanzi. Oku kungenxa yokuba amanzi entambo aya kuchaphazela kakhulu ubomi benkonzo yentambo, kwaye neengozi zesekethe ezimfutshane ziya kwenzeka kwiimeko ezimandundu.
(3) Ngaphambi kokuba wenze iintambo zentambo ezinganyangekiyo emanzini, funda ngokucophelela imiyalelo yemveliso yomenzi.
(4) Xa ucinezela umbhobho wobhedu kwindawo edibeneyo, ayikwazi ukuba nzima kakhulu, nje ngokuba icinezelwe kwindawo. Ubuso besiphelo sobhedu emva kwe-crimping kufuneka bufakwe phantsi ngaphandle kwe-burrs.
5
(6) Ubungakanani bentambo ye-cable shrink ebandayo kufuneka yenziwe ngokungqongqo ngokuhambelana nemiyalelo yokudweba, ngakumbi xa ukhupha inkxaso kumbhobho ogciniweyo, kufuneka uqaphele.
(7) Ukuba kuyimfuneko, into yokutywina ingasetyenziswa kwiintambo zentambo ukuze itywine kwaye iphucule ngakumbi amandla okuthintela amanzi entambo.
