Ngokuqhubeka okuqhubekayo komnotho kanye nomphakathi kanye nokusheshisa okuqhubekayo kwenqubo yokuthuthela emadolobheni, izintambo ezivamile azisakwazi ukuhlangabezana nezidingo zentuthuko yezenhlalakahle, ngakho-ke izintambo ezigqitshwe emhlabathini zavela. Ngenxa yolwazi lwendawo lapho ikhebula elingaphansi komhlaba litholakala khona, ikhebula kungenzeka kakhulu ukuthi lidliwe ngamanzi, ngakho-ke kuyadingeka ukwengeza i-tape yokuvimbela amanzi ngesikhathi sokukhiqiza ukuvikela ikhebula.
I-semi-conductive cushion water blocking tape ihlanganiswe ne-semi-conductive polyester fiber non-woven, i-semi-conductive adhesive, i-high-speed-speed resin emunca amanzi, ukotini o-semi-conductive fluffy nezinye izinto. Ivame ukusetshenziswa emgodleni ovikelayo wezintambo zamandla, futhi idlala indima yensimu kagesi efanayo, ukuvinjwa kwamanzi, i-cushioning, ukuvikela, njll. Kuyisithiyo esisebenzayo sokuvikela ikhebula lamandla futhi sinokubaluleka okubalulekile kokwelula impilo yesevisi yekhebula. .
Ngesikhathi sokusebenza kwekhebula le-high-voltage, ngenxa yamandla anamandla enkango yekhebula emkhakheni wefrikhwensi yamandla, ukungcola, izimbotshana nokugeleza kwamanzi kungqimba lokufakwa kwe-insulation kuzokwenzeka, ukuze ikhebula liphuke kungqimba lwe-insulation. ngesikhathi sokusebenza kwekhebula. I-cable core izoba nomehluko wokushisa phakathi nenqubo yokusebenza, futhi umgodla wensimbi uzokhula futhi unciphe ngenxa yokwanda nokuncipha kwezinga lokushisa. Ukuze uvumelane nokwandiswa kokushisa okushisayo kanye ne-contraction phenomenon ye-metal sheath, kuyadingeka ukushiya igebe ngaphakathi kwayo. Lokhu kunikeza amathuba okuvuza kwamanzi, okuholela ezingozini zokuwohloka. Ngakho-ke, kuyadingeka ukusebenzisa into yokuvimbela amanzi nge-elasticity enkulu, engashintsha ngokushisa ngenkathi idlala indima yokuvimbela amanzi.
Ngokukhethekile, itheyiphu yokuvimbela amanzi yomcamelo we-semi-conductive inezingxenye ezintathu, ungqimba olungaphezulu luyi-semi-conductive base material ene-tensile enhle nokumelana nokushisa, ungqimba olungezansi luyi-fluffy semi-conductive base base material, kanti phakathi nendawo impahla yamanzi okumelana ne-semi-conductive. Enqubweni yokukhiqiza, okokuqala, i-adhesive semi-conductive ixhunywe ngokufanayo kwindwangu yesisekelo ngokusebenzisa ukudaya kwe-pad noma ukugqoka, futhi impahla yendwangu eyisisekelo ikhethwa njengendwangu ye-polyester engalukiwe kanye nekotini ye-bentonite, njll. I-semi-conductive ingxube ibe isilungiswa ezingxenyeni ezimbili zesisekelo se-semi-conductive nge-adhesive, futhi impahla yengxube ye-semi-conductive ikhethwa ku-polyacrylamide/polyacrylate copolymer ukuze kwakhiwe inani eliphakeme lokumuncwa kwamanzi kanye ne-carbon conductive emnyama nokunye. Itheyiphu yokuvinjwa kwamanzi komcamelo we-semi-conductive ehlanganiswe izendlalelo ezimbili zesisekelo se-semi-conductive material kanye nongqimba lwamanzi amelana ne-semi-conductive ingasikwa ibe yitheyiphu noma isongwe ibe yintambo ngemva kokusikwa ibe yitheyiphu.
Ukuze kuqinisekiswe ukusetshenziswa okuphumelelayo kwe-tape yokuvimbela amanzi, i-tape yokuvimba amanzi idinga ukugcinwa endaweni yokugcina impahla eyomile, kude nomthombo womlilo kanye nokukhanya kwelanga okuqondile. Idethi esebenzayo yokugcina iyizinyanga eziyisi-6 kusukela ngosuku lokukhiqiza. Ngesikhathi sokugcina nokuthutha, ukunakwa kufanele kukhokhwe ukuze kugwenywe umswakama kanye nokulimala kwemishini ku-tape yokuvimbela amanzi.
