Ngenkqubela phambili eqhubekayo yoqoqosho kunye noluntu kunye nokunyuka okuqhubekayo kwenkqubo yokufudukela ezidolophini, iingcingo zendabuko ezingaphezulu azikwazi ukuhlangabezana neemfuno zophuhliso lwentlalo, ngoko ke iintambo ezingcwatywe emhlabeni zavela. Ngenxa yobume bemeko yendawo apho ikhebula elingaphantsi komhlaba lihlala khona, ikhebula linokwenzeka kakhulu ukuba lihlanjululwe ngamanzi, ngoko ke kuyimfuneko ukongeza i-tape yokuthintela amanzi ngexesha lokwenziwa ukukhusela intambo.
I-tape yokuthintela umcamelo we-semi-conductive idityaniswe ne-semi-conductive polyester fiber non-woven fabric, i-adhesive semi-conductive, i-high-speed-speed water-absorbing resin, i-semi-conductive cotton fluffy kunye nezinye izinto. Ihlala isetyenziselwa kwi-sheath ekhuselayo yeentambo zamandla, kwaye idlala indima yentsimi yombane efanayo, ukuvalelwa kwamanzi, i-cushioning, ukukhusela, njl.
Ngethuba lokusebenza kwentambo ye-high-voltage, ngenxa yombane oqinileyo we-core cable kwintsimi ye-frequency yamandla, ukungcola, i-pores kunye ne-seapage yamanzi kwi-insulation layer iya kwenzeka, ukwenzela ukuba intambo iya kuchithwa kwi-insulation layer ngexesha lokusebenza kwentambo. I-core cable iya kuba nokuhluka kweqondo lokushisa ngexesha lenkqubo yokusebenza, kwaye i-sheath yensimbi iya kwanda kwaye inkontileka ngenxa yokwandiswa kwe-thermal kunye nokunciphisa. Ukuze ulungelelanise nokwandiswa kwe-thermal kunye ne-contraction phenomenon ye-sheath yensimbi, kuyimfuneko ukushiya i-gap ngaphakathi kwayo. Oku kubonelela ngamathuba okuvuza kwamanzi, okukhokelela ekuqhekekeni kweengozi. Ngoko ke, kuyimfuneko ukusebenzisa i-water-blocking material kunye ne-elasticity enkulu, enokutshintsha ngobushushu ngelixa idlala indima yokuthintela amanzi.
Ngokukodwa, i-tape yokuthintela umcamelo we-semi-conductive inamacandelo amathathu, umaleko ongaphezulu yinto esisiseko semi-conductive ene-tensile elungileyo kunye nokumelana nobushushu, umaleko ongezantsi uyinto eguquguqukayo enesiqingatha-conductive, kwaye umbindi yimathiriyeli yamanzi yokumelana ne-semi-conductive. Kwinkqubo yokuvelisa, okokuqala, i-adhesive semi-conductive enamathela ngokulinganayo kwilaphu lesiseko ngokusebenzisa ukudaywa kwephedi okanye ukutyabeka, kwaye isiseko selaphu lezinto ezikhethiweyo zikhethwa njengelaphu le-polyester engalukiweyo kunye nomqhaphu we-bentonite, njl njl. i-polyacrylamide/polyacrylate copolymer ukwenza ixabiso eliphezulu lokufunxa amanzi kunye ne-carbon conductive emnyama njalo njalo. Iteyiphu yokuthintela amanzi yomqamelo wesemi-conductive eyenziwe ngamanqanaba amabini esiseko semi-conductive kunye nomaleko wesixhobo samanzi esichasayo semi-conductive inokusikwa kwiteyiphu okanye ijijelwe ibe yintambo emva kokusikwa kwiteyiphu.
Ukuze kuqinisekiswe ukusetyenziswa ngokufanelekileyo kwetape yokuthintela amanzi, i-tape yokuthintela amanzi kufuneka igcinwe kwindawo eyomileyo, kude nomthombo womlilo kunye nokukhanya kwelanga. Umhla osebenzayo wokugcinwa kwiinyanga ezi-6 ukususela kumhla wokwenziwa. Ngexesha lokugcinwa kunye nokuthutha, ingqalelo kufuneka ihlawulwe ukuphepha umswakama kunye nomonakalo womatshini kwi-tape yokuthintela amanzi.
