What are the types of lightning protection devices?

The lightning arrester is also named: lightning arrester, surge protector, surge protector, abbreviation, SPD, including: power supply lightning protection device and signal lightning protection device, and antenna feed lightning protection device.

In the information age today, computer networks and communication equipment are becoming more and more sophisticated, and their working environment requirements are getting higher and higher, and instantaneous overvoltages of lightning and large-scale electrical equipment will increasingly pass through power supplies, antennas, and radio signals. Lines such as transceivers invade indoor electrical equipment and network equipment, causing damage to equipment or components, personnel casualties, transmission or storage of data being disturbed or lost, and even causing electronic equipment to malfunction or temporarily collapse, system stalls, and data transmission interruptions. LANs and even wide area networks are destroyed. The danger is shocking and the indirect loss is generally much greater than the direct economic loss. Lightning arresters are devices that prevent lightning from being hit by modern electrical and other technologies.
