Level c shielding cabinet. For example, the c-class shielding cabinets of science are characterized as follows:
1. Block effectiveness: 14khz≥70db 50khz≥100db 450khz≥100db 930khz≥100db
2. Appearance: appearances and colours according to a
3 shells: fully closed boxes welded by 1. 5 mm cold-rolled steel plates, corrosively treated with zinc plating and paint
4. Front door shielding: high-quality materials are carefully constructed and processed shielding springs, cold-rolled steel plate welded doors, with additional back doors and locks as required
5 equipment stubble: adjust position up and down, with 20 bolts
6 prevention server layers: common 2m cabinets with three layers board
7. Ventilation wave steering windows: beehive formation, 300*300 mm each, axle current at top machine
Leachers: power filters with wide inhibiting bands and high penetration losses
Network-line transmission tubes: copper transmission line wavers with thallium 8*120 mm elastic headers pipe
10, optical wave tubes: thallium 14*140 mm copper plating light transfer waver pipe
11 - ground-to-ground electrical resistance: more than 1,000 land-to-ground electrical resistance should occur in the absence of ground

In accordance with our electronic information system suite design code (gb 50174-2008), data centres are classified into levels a, b and c depending on the nature of their use, the management requirements and the extent of the economic and social losses or impact of the disruption of the operation of electronic information systems due to site equipment failure。
Level a is faulty and the site equipment of the system should not be disrupted by operational failure, equipment failure, interruption of external power supply, maintenance and overhaul of the system during its operation. The applications are: national meteorological stations, information centres, key military command units, airports in large and medium cities, electronic information system rooms such as national and regional power dispatch centres and important control rooms。
Level b is redundant, and the site equipment should be within redundancy capacity during the time the system needs to operate and should not be disrupted by equipment failure. Applied industries include: scientific research institutes, higher education institutions, meteorological stations in cities and cities, information centres, power dispatch centres, traffic command and control centres, international conference centres, etc
Level c is basic and, in the case of normal operation of the site equipment, the electronic information system shall be guaranteed uninterrupted operation. Applications include users with barrier-free needs such as buildings, electronics, medical, office, etc。
In addition to level a, b, the ability to effectively suppress the release of computer electromagnetic information and prevent external strong electromagnetic disturbances affecting the normal operation of computers meets the level c requirement
