With the rapid development of modern science and technology, radio and television transmission, transmitting stations, electronic equipment and communication equipment are increasing, audio and video signal transmission lines exposed outdoor are longer and longer, and the probability of lightning stroke is greatly increased.
With the rapid development of modern science and technology, radio and television transmission, transmitting stations, electronic equipment and communication equipment are increasing, audio and video signal transmission lines exposed outdoor are longer and longer, and the probability of lightning stroke is greatly increased. In addition, the working voltage of integrated circuit in modern electronic equipment is lower and lower, and the distance between lines of printed circuit board is smaller and smaller, which makes the equipment lightning resistant The force is getting weaker and weaker.
