Cell phone jammer is manufactured by applying the advanced foreign technology

Different occasions using different electromagnetic interference shielding structures and shielding materials. In the cabling, the design unit should be in accordance with the surrounding environment and interference signal wiring crosstalk within the system to choose a reasonable level of communication cable model.   cell phone jammer is manufactured by applying the advanced foreign technology.Taking into account the needs of next-generation communications technology, and strive to achieve the communication network, "a framework for long-term evolution" of the technical objectives. 2, various shielding and structure of the cable shield in the form of semi-conductive shielding material extruded shield, shielding tape around the package or longitudinally, vertical bag with metal / welding / around the bag, foil wrapping / drag bag, metal silk weaving, wire wrapping, metal extrusion seamless shield (such as lead sheath), metal tube suite.   cell phone jammer  is also used in prisons, detention houses courts, police stations and so on. In the communication cable production, the main drag metal foil packages, and metal wire woven with welding. Way in accordance with the data cable shielding, ISO11801, TIA / EIA 568 B.2, IEEE 802.3 common technical standards and other international data cable into the UTP, FTP, STP, SFTP four major cable types. With the rapid development of communications technology, new materials, new forms of cable shielding technology is bound to be shipped out. The shielding radius range of  china cell phone jammer depends on signal strength of site working environment.Here focuses on newly emerging communication cables manufactured in several technologies, for reference. Double helix-shaped shield: the double helix-shaped shield: Spiral shielded cable with copper wire tightly around for spiral wound. Wrapped twice around the time the opposite is also known as "double spiral shield", or more than the traditional single spiral braid shield reduces microphonic noise or static. Spiral shielding to the price range of copper mesh shielding and foil shielding between the price.  cell phone jammer   guarantees that the confidential information would not be leaked. End of the process is relatively simple, but very active spiral shielding performance will not fall, spiral shield is designed for fixed installation. Than a single double-helix spiral shield shielded DC loop resistance must be low, performance is better. Braid: braid: braid to maintain good flexibility and flex life, while providing superior structural integrity. This shield for reducing low-frequency electromagnetic interference is the ideal choice. Compared to foil shielding, the lower the DC resistance. Mesh screen and the audio frequency range (0.03-0.3MHz) is very effective. Generally, the more dense mesh screen cover, shield, the better. Foil shielding layer shielding foil: foil shielding is integrated in a thin polyester film or a thin aluminum foil made of copper with a wound on the cable.
Foil shielding braid flexibility than better, but shorter flex life. The emission power of   cell phone jammer  is 4W in total. And foil shielding for use with ground wire, so that termination easier, and electrostatic discharge into the earth.
The cable terminal treatment is simple and has good mechanical strength and insulation properties, commonly used in the line of the data cable between the shield and overall shield. Cheaper price of money, intended for fixed installation. For the need to pass through metal foil layer tube wiring shielded cables must be sheathed with a high tear strength rope in order to improve the tensile strength of the cable.
