Guano flashover waxa ay leedahay laba qaab: mid waa bakhti-dhaafka ka dhashay isu-ururinta dusha dahaarka.Si kastaba ha ahaatee, sababtoo ah shimbiraha waxaa u kala sooca qaybo badan oo dallad ah, suurtogalnimada in ay si toos ah u soo baxaan waa mid aad u hooseeya.Midda kale waa guano silbashada dahaarka oo ku dhacaya agagaarka bannaanka, xudunta tooska ah waxay keenaysaa dheecaan gaaban oo u dhexeeya qalabka dahabka sare iyo hoose, iyo wax raad ah oo guano ah oo ku hadhay sueko, taas oo sidoo kale ah qaabka ugu muhiimsan ee guano flasing.Iyada oo ku saleysan si guul leh u jilitaanka ifafaale shimbiraha insulator, waaxda injineernimada korantada ee jaamacadda tsinghua ayaa baratay habka flashover iyo xaaladaha guano, waxayna soo gabagabeysay in xilliga guano ee dhacaya ay aberrates qaybinta beerta korantada ee ku wareegsan insulator, taasoo keentay Burburka faraqa hawada ee kanaalka guano ee dhamaadka sare ee dahaarka, taas oo horseedaysa in ay soo baxaan insulator.Haddii aan tusaale u soo qaadano 110 kv synthetic suozi, wareegga leh dhexroorka 55cm waa in uu ilaaliyaa fantiyan.Isla mar ahaantaana, tixgeli in guano dabayshu ay u dhici doonto sida parabola.Shaqada dhabta ah, aagga isgoysyada sare ee munaaradda waxaa loo tixgalin doonaa furaha ka hortagga shimbiraha inta u dhaxaysa 30-45° oo leh xarigga insulator-ka oo ah barta salka iyo xagasha u dhexeysa labada dhinac.Marka labaad, qodxaha shimbiraha si loo hubiyo cufnaanta qaarkood, shimbiraha ayaa si buuxda u "ku dheji" meel ka baxsan aagga ilaalinta.

Codsiga injineernimada, oo ay ugu wacan tahay nooca munaaradda ee kakan, meelaha muhiimka ah ee ilaalinta shimbiraha ayaa laga yaabaa in laga tago, taasoo keentay inay dhacdo cillado waxyeello shimbiraha aan caadiga ahayn.Shimbiraha ka soo boodaya insulator-ka siligga saddexda weji ah ayaa lagu rakibay meesha, laakiin qodax shimbireedka laguma rakibin tiirka dhulka ee ka sarreeya siliga dhinaca, taas oo ka tagaysa dhibaatada qarsoon ee dhacdada qaladka.
