What is a triaxial cable?
triaxial cable is a type of cable that is often used in communication, especially in the television industry. This is called "triaxial" because it consists of three separate conductive elements, usually arranged in alternating concentric circles of conductors and protected insulation. Shielding and insulation prevents individual signals from the wires to interfere with each other. The connectors for these cables are specially designed to prevent accidental use with other types of connectors and cables.
The design of the triaxial cable, when it is shown in the cross -section, resembles the bull's eye. The center of the cable or core consists of a conductor that is generally the only fixed wire, but it can be a knitted wire. The core is closed by insulating shielding. Around it is another layer of conductor, which can also be solid or knit, followed by another layer of shielded insulation. The third conductive layer, which can also be solid or knit, is wrapped around the Inner two layers and the cable is finished with the final outer layer of shielding.
today isAvailable several different triaxial cable stages. The common sizes of the triaxial cable include 14 mm, 11 mm and 8 mm, measurement referring to their thickness. Resistance may also vary, including 50 ohms, 75 ohms and 90 ohm cables, but the most common types have a resistance of 75 ohms.
The main difference between the triaxial cable and the typical coaxial cable is that the triaxial cable can act as a power conductor and a signal conductor, and for this reason the TV industry is often used by a triaxial cable to connect TV cameras with their control units. With this type of cable, the control unit is able to provide the camera power and also transmit and receive signals, all at the same time. Many places that regularly organize television events have its own triaxial system system, which allow TV crews to quickly set up on site broadcasting.
triaxial cable is generally notIt is in domestic applications, but at least one company establishes a signal distribution system for a house that can distribute a signal to multiple domestic units. This type of system can combine multiple signal sources and then distribute them to several separate locations in the home. These units are designed for use with satellite systems and can combine and supply a closed circuit, regular TV signals, satellite signals and even standard FM signals. However, these systems have been relatively unknown outside Europe since 2011.
