Guano flashover ali mitundu iwiri: imodzi ndi flashover chifukwa kudzikundikira insulator pamwamba.Komabe, chifukwa mbalame zimasiyanitsidwa ndi zigawo zingapo ndi ambulera ya insulator, mwayi wa flashover mwachindunji ndi wotsika kwambiri.Chinanso ndi kutchinjiriza kwa guano kugwera kudera lakunja, phata lachindunji limabweretsa kutulutsa kwafupipafupi pakati pa zida zam'mwamba ndi zam'munsi za golide, ndipo palibe zotsalira za guano zomwe zimasiyidwa pa sueko, womwenso ndi mtundu waukulu wa guano flassing.Pamaziko a kutengera bwino chodabwitsa chodabwitsa cha mbalame za insulator, dipatimenti yamagetsi yamagetsi yaku yunivesite ya tsinghua idaphunzira momwe zimagwirira ntchito komanso mawonekedwe a flashover a guano, ndipo adatsimikiza kuti mphindi yakugwa kwa guano imasokoneza kugawa kwamagetsi kuzungulira chotchingira, ndikupangitsa Kuwonongeka kwa mpweya wa njira ya guano kumapeto kwenikweni kwa kutchinjiriza, motero kumabweretsa kuphulika kwa insulator.Kutengera chitsanzo cha suozi yopangidwa ndi 110 kv, chozungulira chomwe chili ndi mainchesi 55 cm chiyenera kutetezedwa ndi mafani.Panthawi imodzimodziyo, ganizirani kuti mphepo yamkuntho idzagwa ngati parabola.Pantchito yeniyeni, malo opingasa pamwamba pa nsanja adzawonedwa ngati chinsinsi chopewera mbalame mkati mwa 30-45 ° ndi chingwe cha insulator ngati maziko ndi Angle pakati pa mbali ziwirizo.Kachiwiri, mbalame munga kuonetsetsa ena osalimba, mbalame kwathunthu "pulagi" kunja kwa chitetezo zone.

Mu ntchito ya uinjiniya, chifukwa cha mtundu wovuta wa nsanja, madera ena ofunikira chitetezo cha mbalame amatha kusiyidwa, zomwe zimapangitsa kuti pakhale zolakwika zachilendo za mbalame.Mbalame spikes pamwamba insulator wa magawo atatu waya waikidwa m'malo, koma mbalame munga si anaika pa nthaka mzati pamwamba pa mbali waya, amene amasiya zobisika mavuto chifukwa cha vuto.
