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, ukugoba, ukuvikela, njll. Kuyisithiyo esisebenzayo sokuzivikela sekhebula lamandla futhi sinokubaluleka okubalulekile kokwelula impilo yesevisi yekhebula.
Ngesikhathi sokusebenza kwekhebula le-high-voltage, ngenxa yamanje eqinile ye-cable core emkhakheni we-frequency yamandla, ukungcola, ama-pores kanye ne-sepage yamanzi kungqimba lokufakwa kwe-insulation kuzokwenzeka, ukuze ikhebula lizophulwa kungqimba lokufakelwa 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.
Ikakhulukazi, itheyiphu yokuvimbela amanzi yomcamelo we-semi-conductive inezingxenye ezintathu, ungqimba olungaphezulu luyi-semi-conductive base material enokuqina okuhle nokumelana nezinga lokushisa, ungqimba olungezansi luyi-fluffy semi-conductive base base material, kanti phakathi nendawo luyi-semi-conductive resistance resistance. Enqubweni yokukhiqiza, okokuqala, i-adhesive semi-conductive ixhunywe ngokulinganayo kwindwangu yesisekelo ngokusebenzisa ukudaya kwephedi noma ukugqoka, futhi impahla yendwangu eyisisekelo ikhethwa njengendwangu ye-polyester engalukiwe kanye ne-bentonite ukotini, njll. i-polyacrylamide/polyacrylate copolymer ukwenza 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.
