Shielded wire, as the name suggests, is a number of signal shielding wire products, they tend to use a metal mesh woven into the signal line to wrap the transmission line products, shielded wire shielding layer needs to be grounded, foreign interference signals through this type of material will be able to be imported into the earth, so as to achieve our purpose. So the next example for you is about the shielded wire information, including the manufacturer's recommendations and the difference between shielded and unshielded wire comparison. Interested in understanding or want to consume learning friends can refer to these parts of the content, comparison of examples of appropriate acquisition program, with accurate operation to achieve satisfactory results.
A, shielded and unshielded wire difference
Shielded refers to each line has its own shielding layer of shielded wire, also called shielded twisted-pair cable, shielded twisted-pair cable wrapped with a layer of shielding with a layer of metal film, which is better anti-interference performance. It should be noted that the shielding is only in the entire cable are shielded, and both ends of the correct grounding of the case will play a role. Therefore, it is required that the whole system is all shielded devices, including cables, sockets, crystal heads and patch panels, etc., while the building needs to have a good grounding system.
Unshielded network cable is also called unshielded twisted-pair cable. Twisted-pair cable by 8 very different colors of the wire into 4 pairs of twisted together, twisted in pairs is to minimize electromagnetic radiation and the impact of external electromagnetic interference. Unshielded cable diameter is small, saving the space occupied; light weight, easy to bend, easy to install, so most LANs use unshielded twisted-pair cable as a transmission medium for cabling to the network, the cable by a certain distance from the long twisted-pair cable and RJ45 header composition.
Two, shielded wire models (RVVP) and (KVVRp) what is the meaning of each?
RVVP is a soft conductor PVC insulated wire plus shield and PVC sheath cable. Copper core PVC insulated and shielded PVC sheathed flexible cable, also called electrical connection anti-interference flexible cable.
KVVRP copper core PVC insulated PVC sheathed braided shielded control flexible cable, more suitable for use in signal interference areas.
Three, shielded wire manufacturers
1, Shanghai Changhu High-temperature Cable Co. The company has a group of high-temperature wire production, research and development of more than 20 years of technical elite, while the use of domestic and foreign leading production equipment, technology and equipment to ensure that product quality to achieve the national leading level. Changshu produces a wide variety of product types, mainly including all kinds of high-temperature integrated cable, Teflon high-temperature wire, silicone high-temperature wire, coaxial cable, compensation wire, computer cables, nylon sheathed wire, fire-resistant wire, aircraft Lark line, towing flexible cables, communication cables and all kinds of special cables, etc., which can be widely used in the aerospace, military machinery, automotive, petrochemical, electronic and electrical appliances, metallurgy, shipbuilding industry, electromechanical, communication, medical, steel, lighting and many other industries. In addition, we can customize our own non-standard products according to customers' requirements to provide better solutions to meet the actual project.
The company adheres to the "technological innovation, quality first, service first" business philosophy.
2, Hefei CCTF was founded in 2002, is a new high-tech enterprises, the whole army confidential security products designated suppliers. In the process of development, the company is committed to security products as well as information security products, all the company's products are the company's self-developed products. As the largest and most professional cell phone signal blocker pioneer, the company has senior wireless mobile communication and information security experts, with strong R & D and production capacity, with independent intellectual property rights of the core technology, is committed to meet the growing needs of society. With strong economic strength, the production of cell phone signal shielding unique military quality, the machine on the human body without radiation, by the national enrollment offices in all provinces designated recommended, become the first brand of quality Miles.
In the actual production of some areas of life, we will find ourselves wanting to harvest the signal is shielded by it, or to put it in another way, we may find that there are some unwanted interference signals will affect our operation, so this time to choose to purchase a shielded wire is a very good suggestion, the above is about the shielded wire on the basis of a variety of basic sections of information, including Shielded wire and non-shielded wire difference comparison, in addition, there are recommended manufacturers of the description of the text, interested in understanding or want to consume friends can use the content of these boards, I believe that can reap satisfactory results.
