EMI Shielding Changgao Electric Group Co., Ltd.
Shielding project in the test hall of No. 5 plant
Screening hall size: 37.7×30.4×20(H)m
Completion in June 2022
Grounding and Bonding: Proper grounding and bonding systems are implemented in integrated shielded halls to provide a low impedance path for any electromagnetic currents. This helps to divert and dissipate external electromagnetic interference safely into the ground, reducing its impact on the sensitive equipment.
Filtering and Suppression: Power and signal lines entering the integrated shielded hall undergo filtering and suppression measures. Filters are employed to attenuate and block unwanted electromagnetic frequencies, while suppression techniques, such as ferrite beads or chokes, are used to suppress electromagnetic noise present on the signal lines.
Together, these mechanisms create an electromagnetically isolated environment within the integrated shielded hall, effectively shielding sensitive equipment from external electromagnetic interference. This ensures that the equipment operates in a controlled and interference-free environment, allowing accurate testing, reliable performance, and protection against data corruption or malfunction caused by external electromagnetic sources.
