Coaxial Cable is a kind of wire that is used to transmit radio and television signals. It is widely used in many applications, including home video equipment, satellite dishes, and avionics. There are several different types of coaxial cables available. These include semi-rigid, formable, and triaxial cable. Coaxial cable is commonly used to transmit radio frequency (RF) signals, such as those used in cable television (CATV) and cable internet networks, as well as in other applications that require high-frequency signal transmission, such as scientific instrumentation, industrial control systems, and medical equipment.
Coaxial cable is known for its ability to maintain a consistent signal level over long distances and to reject interference from external sources, making it a popular choice for many communication applications. Triaxial or triax cable has a third layer of insulation, which is a copper braid. This helps to shield the signal against electromagnetic interference (EMI). Coaxial cables are typically made of four layers. The innermost layer is the center conductor. The second layer is the dielectric. Dielectric materials are usually plastic or foam. The next layer is the shield. This protects the center conductor and the dielectric from external interference. Normally, the shield is grounded. In some cases, spacers are used to keep the inner conductor away from the shield. Finally, the outer shield surrounds the whole assembly and provides the ground. Typically, the outer metal shield is grounded in the connector at both ends of the line. A coaxial cable is ideal for weak electrical signals. However, it can also be susceptible to damage. As a result, it should be handled carefully. To avoid damage, it should be coiled correctly before transportation.
