The system equipment adopts digital base station technology and computer intelligent management and control technology, the system only needs to reach the signal field strength equivalent to the traditional base station and enable effective mobile signal control of coverage areas, the electromagnetic radiation of the personnel in the coverage area is far less than the radiation standard stipulated by the state, and will not cause long-term radiation damage to the human body. The system consumes a significant amount of electricity, which is also called green shielding.
Shielding area mobile phone manange and control, at the same time, combined with the passive antenna feed distribution system, uniformity wireless signal coverage is performed on the required shielding area. It can effectively control the external signal leakage, and implement bundled communication blocking for illegal mobile phones in the coverage area. There will be no blind spots and dead ends, and no signal interference will be caused to the surrounding normal mobile phone users and carrier base stations.
Can set whitelisted mobile number in the system, ensure that the prison guards mobile phone normally working, while in blocking area effective shielding illegal mobile phone with the surrounding base station communication, through mobile phone number intelligent indentification tehnology, the user of the preset mobile number can be kept in normal communication with the original base station.
When the system is in communication and computer intelligent identification control, obtained the serial number, sim card number or feature number in the effective control area, intercept the text message sent by the mobile phone and the dialed phone number, and also in the control center can send fraudulent messages such as" network busy" or " Dial-out usrs not in the service area" to the specific mobile phone in the caverage area, and thus provide a powerful means for the prison administrators to timely grasp the information of criminal activities and prevent crimes.
It can carry out large-area and high-efficiency search work on the confidential areas that are prohibited from entering the mobile phone, and realize the functions of shielding, locating, and grabbing the searched mobile phones, cause hidden trouble and danger to secret safety. The system is mature and will not interfere with the normal operation of the communication network.
The basic functions of the system include:

Building wires can also be divided into three types according to the hardness of conductors.
H05V-U/H07V-U voltage class 300/500 or 450/750V. It is the most commonly used connection line for household wiring, mainly used for power supply, lighting, sockets, air conditioners and other daily household lines
H05V-R/H07V-R voltage grade is 450/750V, which can be used for home lighting lines. It is good to use when the wiring is soft and the circuit turns too much, which is convenient for electricians to wear pipes.
H05V-K/H07V-K voltage class 300/500V or 450/750V household decoration is generally not used, and it is suitable for flexible installation sites with strict requirements, such as electrical control cabinets, distribution boxes and various low-voltage electrical equipment.
What is a flexible copper cable?
Copper flexible cables are commonly used to connect portable equipment and appliances. Their flexibility allows them to withstand the movements or vibrations present in a particular application.Flexible copper cables are made from multiple strands of fine copper wire. The conductor is made of normal annealed copper of category 4 and 5. The cable has more than 6 different coloured cores. The insulation and sheath material must have the usual electrical and physical properties. Flexible copper wire is also soft, oil resistant, low temperature resistant and flame retardant.
Construction
Conductor: Multistrand copper wire
Insulation: PVC
Sheath: PVC
Associated voltage: 450/750V

Applications and features.
Power cables are suitable for use in wet and dry areas, conduits, pipes, slots, trays, antennas supported by messengers, and where excellent electrical performance is required. These cables are capable of continuous operation at conductor temperatures up to 90°C (normal operation in wet and dry locations), 130°C (emergency overload) and 105°C (short circuit conditions). 1/0 AWG and larger are rated for CT use.
