Kuisa nzvimbo yekudzivirira shiri spike:

Zvinonyanya kukonzera shiri kukanganisa kukanganisa shiri flashover, pfupi dunhu dema dendere zvinhu, pfupi redunhu muviri shiri, etc. Pakati pavo, mutsetse rwendo kunokonzerwa nehombe mvura shiri dzakadai Heron mhuri uye stork mhuri pamusoro shongwe inenge 90% yeshiri kukanganisa kukanganisa kutapurirana mutsara, inova chikonzero chikuru chekufambisa mutsara shiri dzine chokuita nerwendo. Kupfupika kweshiri nest material uye gedhi redunhu rinokonzerwa neshiri body short circuit rinonyanya kuitika mumutsetse wekugovera. Naizvozvo, chinhu chakakosha chekudzivirira kukuvara kweshiri ndechekudzivirira kukuvara kweshiri kunokonzerwa neshiri huru. Kudzivirira kuruma kweshiri i "simbi tsono" yakaiswa pashongwe. Chinangwa ndechekudzivirira shiri huru kuti dzifambe pamusoro peshongwe, kuitira kuti uwane chinangwa chekubvisa shiri flashover. Anti bird spike inonyanya kushandiswa kudzivirira flashover ye110 kV kusvika 500 kV mitsetse yekufambisa.
