[0028] In this embodiment, the Class C electromagnetic leakage-proof cabinet is primarily used to protect confidential information and equipment from physical and electronic attacks. The Class C electromagnetic leakage-proof cabinet is manufactured using special materials that can effectively shield external electromagnetic wave interference while preventing internal signal leakage. Its design complies with specific electromagnetic compatibility (EMC) standards. The cabinet 1 typically adopts a sealed design to ensure a relatively closed internal environment to reduce potential information leakage risks. The cabinet 1 is equipped with anti-intrusion devices, such as physical locks, alarm systems, and monitoring equipment, to prevent unauthorized physical access. The cabinet 1 is used as follows: First, when arranging equipment inside the cabinet 1, pay attention to cable management to avoid excessive entanglement and ensure that the cables do not affect the shielding effect of the cabinet 1.
