The commonly used shielded rooms for information leakage prevention mainly include the following:
1. Metal mesh shielded room
The metal mesh shielded room is to install a wooden or metal frame on the wall, top surface and ground of the machine room, and install a copper or iron mesh on the frame to achieve the shielding effect. Depending on the required shielding effectiveness, a single-layer or multi-layer metal mesh shielding layer can be used. The metal mesh shielded room can be used in occasions with general requirements for shielding.
2. Steel plate assembled electromagnetic shielding room
The six-sided steel plate shielding layer of the steel plate assembly type electromagnetic shielding room shell is formed by folding the steel plate by a special machine tool mold into a unit module, and is assembled by bolts, nuts, gaskets and conductive gaskets. The steel plate-assembled electromagnetic shielding machine room meets the needs of possible relocation. The machine room has beautiful appearance, light weight, fast installation, reliable electromagnetic sealing, strong assembly and disassembly technology, and can be used for multiple disassembly and assembly. It is mainly used for shielding performance requirements Higher measurement and testing, information security, EMC testing and other fields and occasions with large shielding area, high shielding performance and some special requirements.
Three, steel plate welding electromagnetic shielding room
The steel plate welded electromagnetic shielding room uses different specifications of modular steel plates to be welded together into a whole. The steel plate welded electromagnetic shielding room has the characteristics of reliable structure, excellent performance indicators, and the scope of use. At present, it is the most widely used, especially suitable for the shielding of various electronic computer rooms and communication rooms, various radio transmission and reception tests, measurements and calculations, electrical discharge tests and tests, and various tests and measurements of electromagnetic compatibility (EMC). And assessment, applicable to all interference and leakage prevention places. The steel plate welding electromagnetic shielding room is made of steel plate formed by large-scale mold folding and gas shielded welding to minimize welding deformation and ensure the flatness of the steel plate.
