Surge Protectors For Indoor Equipment

All indoor metal screens and cabinet enclosures should be welded or bolted to the base channel steel to ensure good contact. The channel steel should also be welded to the cable supports in the cable trench with galvanized flat steel to form a single, integrated grounding network, which in turn forms a complete grounding grid with the outdoor grounding grid.

Lightning protection grounding for computers, communications, and other automation equipment is the primary protective barrier for computers and other electronic equipment within a building. Since communication radios must be connected to antennas on communication towers via signal cables, the outer sheaths of the communication cables must be properly grounded (multiple points of repeated grounding) and connected to the building ground grid to establish equipotential. A surge protective device can also be installed. Communication radios should be equipped with serial port protectors such as the SD12-DB/25. The communication interfaces of other electronic equipment should also be equipped with corresponding serial port protectors, which are essentially various small surge protector and are not listed here. For electronic equipment within a building, the most important thing is to connect the independent grounding grids into a common grounding system. Other grounding schemes, such as separate, independent, or dedicated grounding schemes, are inappropriate and have no practical value in the project. Lightning protection measures should be implemented step by step for all electrical and electronic equipment within a building. First, ensure lightning protection grounding for the building and power supply, then install appropriate surge protection device in the computer room and at each equipment port to truly prevent the intrusion and counterattack of lightning waves.
