Guano flashover ine mhando mbiri: imwe ndeye flashover inokonzerwa nekuungana kwenzvimbo inochengetedza mwenje. Zvisinei, nekuti shiri dzinoparadzaniswa nezvikamu zvakawanda neamburera inochengetedza mwenje, mukana wekuti mwenje upinde zvakananga wakaderera zvikuru. Imwe ndeye guano slippage insulation inowira pedyo nekunze, nucleus yakananga inotungamira mukubuda kwemhepo pfupi pakati pezvishandiso zvegoridhe zvepamusoro nepazasi, uye hapana madonhwe eguano anosara pasueko, inovawo nzira huru ye guano flassing. Zvichibva pakubudirira kutevedzera chiitiko che flashover cheshiri dzinochengetedza mwenje, dhipatimendi remagetsi reyunivhesiti yetsinghua rakadzidza mashandiro e flashover nemamiriro e flashover eguano, uye rakagumisa kuti nguva yekudonha kweguano inokanganisa kugoverwa kwemagetsi kwakatenderedza insulator, zvichikonzera kuputsika kwemhepo ye guano channel pamucheto wepamusoro we insulation, zvichikonzera flashover ye insulation. Tichitora 110 kv synthetic suozi semuenzaniso, denderedzwa rine dhayamita ye55cm rinofanira kudzivirirwa ne fantian. Panguva imwe chete, funga kuti guano yemhepo ichadonha separabola. Pabasa chairo, nzvimbo yeruoko pamusoro peshongwe ichaonekwa senzira yekudzivirira shiri mukati me30-45° netambo yekudzivirira shiri senzvimbo yekutanga uye Angle iri pakati pemativi maviri. Chechipiri, kuti ive nechokwadi chekuti shiri dzine huwandu hwakati wandei, shiri "dzinovhara" zvachose kunze kwenzvimbo yekudzivirira.

Mukushandiswa kwemainjiniya, nekuda kwerudzi rwakaoma rweshongwe, dzimwe nzvimbo dzakakosha dzekudzivirira shiri dzinogona kusara, zvichikonzera kuitika kwezvikanganiso zvisina kujairika zvekukuvadzwa kweshiri. Shiri dzinomira pamusoro pechinhu chinodzivirira tambo yezvikamu zvitatu dzinoiswa panzvimbo yadzo, asi munzwa weshiri hausi kuiswa padanda repasi pamusoro petambo yedivi, izvo zvinosiya dambudziko rakavanzika rekuitika kwezvikanganiso.
