Shielding Cabinet Product Introduction

With the continuous development of electronic technology, electromagnetic interference in the form of electromagnetic interference noise and radiation has intensified, which greatly affects the normal and safe work of various communication electronic equipment such as electronic computers, network servers, switches, etc., and may leak confidential information more seriously. In order to effectively protect various communication electronic equipment and electronic information, the company designed the JN series electromagnetic shielding cabinet, which is a fully enclosed hexahedron composed of steel plates, equipped with ventilation system, communication transmission system and other auxiliary facilities.

The shielded cabinet can be used to place computers, network servers, switches, and other communication electronic equipment, which can prevent electromagnetic waves from harming people, effectively inhibit computer electromagnetic information leakage and prevent the impact of external strong electromagnetic harassment, and ensure that computers and other electronic equipment work normally. The requirements of national standard B level or C level and military standard B level.

Shielding cabinet includes cabinet bottom, top cover, side wall, frame, spring leaf, upper waveguide window, lower waveguide window, door knife, filter, shielding glass, rear door, waveguide, optical end frame, etc.
