How to select the shielding gasket for the PCS cabinet door of an energy storage system?

Selecting the right shielding gasket for the PCS cabinet door is crucial to ensuring the cabinet's shielding effectiveness. Selection should consider:

1. Shielding Effectiveness (SE): Choose gaskets with appropriate SE values based on the EMC standards required by the system. SE curves at different frequencies are typically provided.

2. Environmental Adaptability: Consider the temperature, humidity, and presence of oil or corrosive gases in the cabinet's environment. Select gaskets with suitable outer coatings (e.g., silicone rubber coating, Monel mesh, conductive cloth) to ensure long-term conductivity and elasticity.

3. Compression Deformation and Closing Force: The gasket should be able to be compressed to its optimal design operating range (typically 25%-50% compression) under normal door closing force to provide stable conductive contact while avoiding excessive closing force.

4. Installation Method: Select gaskets with adhesive backing, clip mounting, or screw fixing based on the cabinet door and frame structure.

5. Material Compatibility: Avoid electrochemical corrosion with contacting metal surfaces.
