Qincheng Prison is one of the most famous prisons in China. It was established in 1958 and is located in Qincheng Village, Xingshou Town, Changping District, Beijing (near Xiaotangshan Town). Cheng Kejie and other high-level prisoners. Most of the senior provincial and ministerial officials sentenced in China are concentrated here. Qincheng Prison is also the only prison that is not affiliated with the Ministry of Justice but the Ministry of Public Security.

        At first, there were 4 white buildings in the prison. During the "Cultural Revolution", "senior prisoners" increased, and "bull ghosts and snake gods" had nowhere to be detained, so they were expanded here. In 1967, Qincheng Prison added six buildings and six yards.

        Each cell is 20 square meters with a separate toilet, as well as a toilet and a foot flush. The walls of the re-offender cell are specially designed to prevent prisoners from committing suicide by hitting the wall. There is only one low bed about one foot above the ground in the room. Only when the “communicating materials” need to be written, the management staff will send them into a single school desk for primary school students to use. But perhaps for security reasons, the stool is never there, and the bed is where the prisoner sits on weekdays. All permanent facilities in the room have been removed from the corners and polished to round shapes. Iron wire, broken glass pieces, ropes and even cloth strips, as well as flammable and explosive items, in short, all tools that may be used to commit murder, suicide, and escape from jail are extinct here.

As the basis of the entire weak current system, the integrated wiring system is particularly important in this project. Through strict screening by Party A, in competition with many international and domestic first-class cabling brands, KEG Handian Integrated Cabling, with its many years of design and cabling experience, finally adopted comprehensive network planning, rigorous technical demonstration, practical solutions and Reasonable selection of network cabling products provided the most useful reference for the Beijing Qincheng Prison Project, and finally won the bid!

      The horizontal cable of the entire wiring system adopts six types of shielded wiring systems. As a modern prison, there are higher requirements for the quality requirements of network data transmission and data transmission distance. The final data backbone uses 12-core 10 Gigabit multimode fiber. The low-smoke halogen-free outer sheath has good flame retardancy and attenuation performance is much better than the relevant standards such as ISO / IEC 11801, TIA / EIA 568C. The data level subsystem adopts KEG Korean Electric Group 6 shielded copper cable solution, and adopts KEG Korean Electric Group 6 shielded modular distribution frame and Korean Electric Group 6 shielded modules, which have good short link performance. The voice trunk adopts three types of 50 pairs of large logarithmic copper cables, and the voice distribution frame adopts Korea Electric 100 to 110 distribution frames, which has high stability and adaptability, and realizes a high-density voice solution.

After the cabling system is built and operated, it will provide stable, powerful, and high-quality operation for the entire network system. The structured, modular, standardized, and highly flexible open building integrated wiring system adopted by the system will provide higher bandwidth for information transmission and sharing of computer systems and meet future comprehensive business needs, such as data and voice , Image and video signal multimedia transmission. It is also convenient for future maintenance and expansion.

       The successful completion of the wiring system of the Beijing Qincheng Prison Project will become one of the hallmark examples of Handian's comprehensive wiring in government military projects.
