1. Aging kumu o nā uea a me nā uwea: waho pōʻino.According i ka hana kālailai i nā makahiki i hala iho nei, he nui loa o ka uwea hewa ke kumu e mechanical damage.For laʻana: uea a me ka uwea hoʻokomo 'aʻole hana maʻamau, maʻalahi e hana mechanical poino. He mea maʻalahi hoʻi e hōʻino i nā uea a me nā kaula i ka hana i ka wā o ka hana kīwila ma nā uea i kanu pono ʻia a me nā kaula. he hewa.I kekahi manawa, koʻikoʻi ka pōʻino a hiki mai paha ka hewa pōkole, pili pono i ka hana palekana o ka mana.
2. Aging kumu o uea a me uwea: pulu insulation. He mea maʻamau nō hoʻi a hiki ma nā wēlau o nā uwea a me nā kaula i kanu pololei ʻia a i ʻole i loko o ke kahawai. hui, e hana i ka wai hui a i hui pū ʻia me ka mahu wai, no ka manawa lōʻihi ma lalo o ka hana o ke kahua uila e hana i nā lālā wai, e hōʻino mālie i ka ikaika insulation o ke kaula i hana ʻia e ka hewa.
3. ʻO nā kumu kahiko o nā uwea a me nā uwea: ʻino kino.ʻO ka pale pale e loaʻa i ka corrosion kemika a i ʻole ka electrolytic corrosion no ka manawa lōʻihi, ka hopena i ka hāʻule ʻole o ka pale pale a me ka hōʻemi ʻana o ka insulation, kahi e alakaʻi ai i ka hemahema o nā uea a me nā kaula. koʻikoʻi loa.
4. Aging kumu o ka uwea a me ka uwea: lōʻihi-manawa over-load operation.In overload hana, ma muli o ka thermal hopena o ke au, ka conductor e inevitably wela i ka wā e hele ana ka ukana i ke kaula.I kēia manawa, ʻo ka hopena o ka ʻili o ka hoʻopiʻi, ʻo ka eddy o kēia manawa o ke kila kila a me ka insulation medium loss e hoʻonui i ka wela, kahi e hoʻonui ai i ka mahana o ka uea a me ke kaula. ʻO kaʻelemakule o ka insulation a hiki i ka hoʻokuʻuʻana e wāwahiʻia.ʻOi aku i ke kauwela wela,ʻo ka piʻiʻana o ka mahana o ke kaula e alakaʻi pinepine i ka nawaliwali mua o ka nāwaliwali o ke kaula, no laila, i ke kauwela, he pinepine nā hewa o ke kaula.
5.Aging kumu o ka uwea a me ka uwea: cable hui failure.The uea hui mea ka nāwaliwali loa loulou i ka uwea laina.ʻO ka hewa o ka hui kaula i hanaʻia e ka hewa pololei o nā limahana (ka hana maikaʻiʻole). ka emi ana o ka insulation o ke poo uwea, pela ka pilikia.
6. ʻO nā kumu kahiko o nā uea a me nā kaula: ka honua a me ka mahana. ʻO ke kaiapuni o waho a me ke kumu wela kahi i loaʻa ai ke kaula e kiʻekiʻe loa ke kiʻekiʻe o ka wela o ke kaula, e wāwahi ka insulation, a me ka pahū a me ke ahi.
