One , the main use :
|
The electromagnetic shielding cabinet is chiefly used :
1 , protect computer , network service and communication electron installation
from being revealing of confidential message in the running ;
2 , protect above-mentioned installation from being disturbed of
the outside world electromagnetic wave while running, and assure it work up to
snuff.

|
Two , the feature :
|
|
Lightly and agile and dependable and saves the investment .
|
|
Three , the performance index

C's grade ( FGWS-C1 )
Magnetic field : 14KHz >= 70dB 150KHz >= 95dB
Electrical field : 200KHz~50MHz >= 100dB
Plane wave : 50MHz~1GHz >= 100dB
Microwave : 1GHz~10GHz >= 95dB
B's grade ( FGWS-C2 )
150KHz~930MHz >= 70dB
The test means is according to GB12190-90's criterion

Five , the structure is made up :
|
1 , the shielding case part of the body : The entire hermetic box part of the body that the cold roll plate solders , after galvanizing together with anticorrosion handles such as paint and so on .
2 , shield the door : The high grade stuff goes through to manufacture painstakingly shielding the door shielding that the door leaf that reed and cold roll plate soldered is
made up against what handle .
3 , the wave filter : The power source wave filter has broad suppressed frequency band and tall insertion loss .
4 , the ventilation wave-guide window : The honeycomb type ventilation
wave-guide window , the peak ministry wave-guide window has some minisize axial flow fan
, single put out amount of wind 1.4m3/min .
5 , else : May deploying transmission interface and electrical equipment jack
according to the requirements of customers .
