In order to minimize the interference between the cable, all power lines and signal lines, control lines and test lines and other cable channels are laid independently of each other. Under the elevated floor, there are at least six metal cable ducts with a diameter of 120 (one set of backup metal cable ducts). Each metal cable pipe is equipped with closed-loop lead, alternating current, direct current and weak are separately laid, and darkroom test Equipment and transmitting antenna power independent of each other line.

1. Characteristics
1) Such absorbers have a pyramid-shaped appearance, with blue color (the color can be customized too)
2) Pliable and flexible, the pyramids won’t bend in long-term use, and its absorbing properties won’t be changed within 10 years.
3) Oxygen index:32%(GB/T2406.2-2009), it can meet the requirements of test I voltage-resistant, test II difficulty of flame ignition and propagation, test III flame-resistant test of Navy laboratory report NRL8093(1977).
4) Good environmental performance, all raw materials can meet the environmental requirements, no volatile, no smell and non-toxic.
5) Working conditions: general indoor application
Long-time working temperature: -50°C~90°C
Short-time working temperature: -100°C~120°C
Relative humidity: 55%±15%
Frequency range: 30MHz~110GHz
6) Installation method: it generally use an environmental protective adhesive to paste the absorbers on the shield body; when the absorbers’ height is below 500mm, Velcro installation can be applied; furthermore, we can also adopt the fasteners to install the absorbers, which would facilitate the replacement of absorbers and the relocation of chambers.

We  mainly engaged in product R&D, system design and project contracting in the fields of Antenna measurement system and Anechoic Chambers as well as 5G telecom related testing and servies.

As a high-tech enterprise,we have been awarded a number of national high-grade qualifications, and has passed authentication of ISO9001 Quality Management System, ISO14001 Environmental Management System, and OHSAS 18001 Occupational Health and Safety Management System.

Due to excellent performance and good service, we have been one of the indispensable co-partner of the government, IT has undertaken and accomplished series of major projects in many significant missions including National-level Professional Anechoic Chambers, Largest Integrated Testing Anechoic Chamber in Asia and so on. Besides the outstanding achievement in China, we had exploited the international market actively and had exported the products to more than 80 countries and regions around the world. we also undertook some foreign aid projects from the Ministry of Commerce of the People-s Republic of China and achieved remarkable success.

We look forward to cooperating with the friends all over the world, making mutual benefit, and creating a bright future.
