1、 Composition of anti magnetic library:

1. The shielding shell of the anti magnetic library is made of 2mm-3mm steel plates to form unit modules. The shielding body can be flexibly treated with beam and column wrapping according to the on-site situation to ensure the shielding effect.

2. The shell adopts a gantry frame inside and outside, with high load-bearing capacity and reliable stability.

2、 Performance indicators:

Magnetic field: 14KHz≥90dB

Electric field: 200KHz～50MHz≥110dB

Plane wave: 50MHz～1GHz≥110dB

Microwave: 1GHz～18GHz≥100dB

3、 Anti magnetic door:

1. The effective sizes are: 0.85m × 1.9m, 1.0m × 2.0m, etc. (special sizes can be customized);

2. Switching mode: electric swing screen door, electric sliding screen door;

3. Access control can be implemented in various forms such as facial recognition, fingerprint, password, and card swiping.

4、 Cut off ventilation duct window:

1. The honeycomb core shape of the ventilation waveguide window is hexagonal, with edge distances of 3.2mm, 4.2mm, and 5.2mm, respectively. The wind resistance coefficient is small, 0.25mmHg, and the wind speed is (3m/s)

2. External dimensions of waveguide window: 300mm × 300mm, 600mm × 600mm and other specifications (special dimensions can be customized).

5、 Anti magnetic warehouse power distribution system:

1. According to the size of the electrical load on each device, select power cables with appropriate wire diameters and power filters of different capacities.

2. Widely using low leakage current power filters, the attenuation capability is consistent with the comprehensive efficiency of the anti magnetic library.

3. Install corresponding filters in the weak current section, with attenuation capability consistent with the comprehensive efficiency of the anti magnetic library.

3. Indoor and outdoor distribution control boxes, cable trenches, and pipeline routing shall be installed in accordance with the design requirements.

6、 Grounding system:

The anti magnetic warehouse needs to be connected to the ground, with grounding resistance requirements≤2Ω。

7、 Scope of application:

The anti magnetic library product is suitable for important electronic documents or information storage carriers in procuratorates, governments, archives, archives bureaus and other units（Protection of USB flash drives, storage cards, magnetic tapes, and video tapes to prevent information damage and loss.
