Imbangela eqondile kakhulu yokwehluleka ukuguga kwekhebula ukuwohloka ngenxa yokuncipha kokufakwa kwe-insulation.Ziningi izinto eziholela ekwehlisweni kwe-insulation ebucayi.Ngokusho kokuhlangenwe nakho kwangempela kokusebenza, kungafingqwa kulezi zimo ezilandelayo.
1. Ukulimala kwamandla angaphandle:ukwehluleka okuningi kwekhebula kubangelwa ukulimala komshini.Isibonelo: ukubeka nokufakwa kwekhebula akukona ukwakhiwa okujwayelekile, okulula ukubangela ukulimala komshini;ukwakhiwa komphakathi kumakhebula angcwatshwe ngokuqondile kulula kakhulu ukulimaza izintambo ezisebenzayo.Ngezinye izikhathi uma umonakalo ungewona ongathí sina, kuzothatha izinyanga noma ngisho neminyaka ukudiliza ngokuphelele ingxenye eyonakele ukwenza iphutha, futhi ngezinye izikhathi iphutha elifushane lesifunda lingase lenzeke uma umonakalo unzima.
2. Ukufakwa emanzini:Lesi simo naso sivame kakhulu, futhi ngokuvamile sivela emajoyini ekhebula ekungcwatshweni okuqondile noma emapayipini.Isibonelo, amajoyinti ekhebula angafaneleki kanye namajoyinti enziwe ngaphansi kwezimo zezulu ezinomswakama kuzodala amanzi noma umhwamuko wamanzi ukuthi ungene emajoyintini, enze amagatsha amanzi ngaphansi kwesenzo senkundla kagesi isikhathi eside, kancane kancane alimaza amandla okufaka ikhebula futhi abangele ukwehluleka. .
3.I-Chemical corrosion:Ikhebula ligqitshwe ngokuqondile endaweni ene-asidi ne-alkali, okuvame ukubangela ukuthi izikhali, isikhumba somthofu noma umgodla wangaphandle wekhebula ugqwale.Isendlalelo esivikelayo sibhekene nokugqwala kwamakhemikhali noma ukugqwala kwe-electrolytic isikhathi eside, okuholela ekuhlulekeni kwesendlalelo sokuzivikela kanye nokunciphisa ukufakwa kwe-insulation, okuzophinde kuholele ekuhlulekeni kwekhebula.
4.Ukusebenza kokugcwala ngokweqile kwesikhathi eside:Ukusebenza kokulayisha ngokweqile, ngenxa yomphumela oshisayo wamanje, lapho umthwalo wamanje udlula ikhebula, nakanjani kuzokwenza ukuthi umqhubi ashise.Ngesikhathi esifanayo, umphumela wesikhumba wecala, ukulahlekelwa kwamanje kwe-eddy yezikhali zensimbi, nokulahlekelwa kwe-insulation medium kuzophinde kukhiqize ukushisa okwengeziwe, okuzokwandisa izinga lokushisa kwekhebula.Ngesikhathi sokusebenza okugcwele ngokweqile, izinga lokushisa eliphezulu lizosheshisa ukuguga kwe-insulation, ukuze ukufakwa kuzophulwa.Ikakhulukazi ehlobo elishisayo, ukuphakama kwezinga lokushisa kwekhebula kuvame ukubangela ukuthi ukufakwa kwekhebula okubuthakathaka kuphulwe kuqala, ngakho ehlobo, kukhona amaphutha amaningi wekhebula ikakhulukazi.
5.Isixhumi sekhebula esinephutha:I-cable joint isixhumanisi esibuthakathaka kakhulu emgqeni wekhebula, futhi ukwehluleka kokuhlanganiswa kwekhebula okubangelwa iphutha eliqondile labasebenzi (ukwakhiwa okungalungile) kuvame ukwenzeka.Enkambweni yokwenza izihlanganisi zekhebula, uma kunezintambo zangempela ezifana nezihlanganisi ezingacindezelwa ngokuqinile noma ezingashisi ngokwanele, ukufakwa kwekhanda lekhebula kuzoncishiswa, okuzodala izingozi.
6.Imvelo nezinga lokushisa:Indawo engaphandle kanye nomthombo wokushisa lapho ikhebula itholakala khona futhi kuzobangela ukuthi izinga lokushisa lekhebula libe phezulu kakhulu, ukuhlukana kwe-insulation, ngisho nokuqhuma nomlilo.
