The lightning arrester is also named: lightning arrester, surge protector, surge protector, abbreviation, SPD. In the information age today, computer networks and communication equipment are becoming more and more sophisticated, and the requirements of their working environment are getting higher and higher. The instantaneous overvoltage of lightning and large electrical equipment will pass the power, antenna and radio signals more and more frequently. Lines such as transceivers invade indoor electrical equipment and network equipment, causing damage to equipment or components, causing personal injury or death, data transmitted or stored being disturbed or lost, or even causing electronic equipment to malfunction or temporarily paralyze, system stalls, and data transmission is interrupted. The LAN and even the WAN were damaged. The damage is shocking, and the indirect losses are generally far greater than the direct economic losses. The lightning arrester is a device that prevents lightning strikes through modern electricity and other technologies.
