Cabinet how lightning protection

Computer data era, to the requirement of lightning protection cabinet has a strong, modern computer room construction, precision instruments used very much, but the precision for lightning resistance is very weak, this requires, external use of cabinets for lightning protection function is more strict, so how are the cabinet lightning-proof?
1, for all the bare wire on chassis cabinets, network line, telephone line to install all the corresponding power supply prevents thunder and signal lightning protection, prevent from outside the power cord and signal lines caused by lightning intruded into the damage to the equipment, so that you can guarantee in the process of the work to prevent the intrusion of the thunderbolt.
2, ensure company away from the doors and Windows, such as trees, at the same time try to make each line separated as far as possible, whether distance have 0 to the walls. 5 meters, don't put chassis cabinets near the Windows and doors, get closer, can from the walls, doors and Windows, caused by lightning intruded into check for other circuit wiring and wiring of chassis cabinets laid together, as far as possible.
3。 Set the room equipotential bus and grounding, ensure the grounding resistance is less than 4 ohm, the chassis cabinets metal case do equipotential connection on the bus.
the right reasonable lightning protection measures for chassis cabinets products, can avoid to cause natural disasters for chassis cabinets as well as the harm of internal precision instruments, to minimize harm, reduce the cost borne by an enterprise in its maintenance.
