EMI Shielding System Electromagnetic Interference EMI Shielding

Product Description
EMI Shielding Hunan Electrical Appliance Science Research Institute





Shielding hall size: 34.55×29.55×32(H)m, 1 set, 11×9.55×6(H)m, 1 set


Completion in December 2020



The integrated shielded hall consists of the following key systems:



Filtering and Suppression System: To further reduce internal electromagnetic
interference, the integrated shielded hall features a filtering and suppression
system. Power and signal lines undergo treatment with filters, suppressors, and
other electromagnetic interference suppression devices to eliminate internal
electromagnetic noise, ensuring the accuracy and reliability of electronic
equipment.



Lighting and Ventilation System: The integrated shielded hall includes lighting and
ventilation systems to provide a comfortable and practical working environment.
These systems require special design considerations to avoid introducing
electromagnetic interference or compromising the shielding effectiveness.



Auxiliary Equipment and Facilities: The integrated shielded hall is typically
equipped with auxiliary equipment and facilities such as workbenches, test benches,
power supplies, instrumentation, and other supporting devices to facilitate
electronic equipment testing, research, and development activities.



The combination and coordination of these systems enable the integrated shielded
hall to provide an electromagnetic shielding, controlled, and secure environment,
protecting sensitive equipment from external electromagnetic interference and
ensuring the accuracy and reliability of testing and research endeavors.
