Shielding room is a 6-surface shielding body,overall electrical connection among these 6-surface 

Efficiency after electromagnetic shielding (to meet requests for PD testing ) 0.5~1.6MHz ≥60dB
 
Grounding resistance of grounding electrode< 0. 5Ω
 
Main parts
1.Shielding door
* Manual squeeze shielding door
* Single or double plat open door with single knife swift and double reed
* Manual (electric) airtight shielding moving door: Its characteristic is new structure, high shielding efficiency, long life, saving space, saving energy opened and closed, be convenient operation and maintenance.
* Various series of specification to be chosen.
2. Shielding observation window
* Shielding observation window is made by import shielding glass, has high fidelity and fine definition advantages.
* Special made high-performance magnetic shielding observation window (dealt with special technology), the efficiency is the same as shielding room, no interference fringe, high definition.
* Various series of size to be chosen.
* The frame adopts door pocket decoration, has elegant appearance.
* Can be made as a large area or one wall shielding observation window.
3. Ventilate wave-guide window: made by the special made copper cellular wave-guide window with low wind resistance of our company, and the new developed large aperture and low voltage resistance, high performance wave-guide window. Its performance is the same as the shielding room.
4. Conduction frame and board: manufacture it according to the supplied blueprint, and manufacture it as wardrobe or cupboard.
5. Quench pipe: used in super conduction, and match the brute force wind machine to exhaust. It will be manufactured for the condition of the place.
