3.0 thunders and lightnings insulate
Thunder and lightning insulate, and refers to when having thunder and lightning between the band conductor of thunder and lightning two or with not producing insulation between lightning conductors and other electric conductors
The insulation of breakdown；
Thunder and lightning insulation is new ideas in a lightning protection, due to identical thunder and lightning between each conductor difference caused by lightning voltage size
Amplitude is different, and different thunders and lightnings is also different in the big small magnitude of conductor point-to-point transmission lightning voltage, so the thunder and lightning insulation of conductor
It is not to have used insulating materials, there is what is be achieved that after operational insulation.
Thunder and lightning insulation show as some insulating materials insulated in thunder and lightning it is pressure-resistant more than the not breakdown property of lightning voltage,
Show as insulating materials of some structures between the two conductors property not breakdown in thunder and lightning.
（1）Lightning voltage, lightning current maximum estimated value：Lightning voltage, lightning current maximum estimated value refer to two conductor when having thunder and lightning
