Do You Want to Know More About Coaxial Cable

Coaxial Cables are widely used for the transmission of electrical energy for one location to another.  Coaxial Cables derive their name because of the peculiar configuration in which a dielectric medium separates two conductors. The outer and inner conductors form concentric cylinders with a common axis and hence the name Coaxial Cables.

Construction Of Coaxial Cables:
The central conductor in a Coaxial Cable can be made from a number conducting metals or alloys including copper, tin, silver plated copper, copper clad aluminum, etc. This conductor may be solid or stranded depending upon the application of the cable. The dielectric medium, separating the two conductors is generally made up of materials like polyethylene (PE), polypropylene (PP), fluorinated ethylene propylene (FEP), and polytetrafluoroethylene (PTFE).

The outer conductor is made by braiding together a number of small copper or aluminum conductors. In high frequency applications, there is a need for better attenuation and shield effectiveness. So, in some of the Coaxial Cables there may be additional aluminum foil tapes covering the dielectric core. The jacket material acts as a protective covering also impart flame retardant properties to the cable.

Electrical Properties Of Coaxial Cables:

• Characteristic impedance is the total obstruction to the flow of current within the cable. It is expressed in Ohms and most of the Coaxial Cables are designed as 50 ohm, 75 ohm, and 93 for various applications.
• Capacitance, the capacity of cable to hold electric charge, should not be very high and Coaxial Cables are designed keeping this aspect in mind.
• The frequency and length of the Coaxial Cable determines attenuation or power loss within the cable.
• Thermal dissipation is during transmission is low.

Applications:
Coaxial Cables find a number of applications in various industries. These cables are widely used for video distribution.  Their electrical and physical properties make them ideal for Radio Frequency and microwave transmission.

The Use Of Coaxial Cables

Being the most commonly used type of Electrical Cables for the transmission of electrical energy or signals, the Coaxial Cable or the Coax Cable has a basic and easy to understand design. Connecting the source to a load and transmitting the signal from one point to the other, the Coaxial Cables have two conductors namely, the Central Conductor and Outer Conductor that form concentric cylinders with a common axis and are separated by a Dielectric Material, also called insulation. The Dielectric Material has to have a good amount of stability as far as its electrical characteristics such as dielectric constant and dissipating factor are concerned.

Range Of Coaxial Cables
The market has a wide range of the Coaxial Cables that can be availed as per the specific needs of the user. The range of the Coaxial Cables is as follows:

•  75 Ohms Coaxial Cables
• RG-59 Drop Cable
• RG-6 Drop Cables
• RG-11 Drop Cable
• 412 Series Cable
• 500 Series Cable
• 540 Series Cable

·    50 Ohms Coaxial Cables

•  50 Ohms Corrugated Copper Tube
•  50 Ohms Radiating
•  Braiding – Type 50 Ohms

Uses Of Coaxial Cables
The Coaxial Cables have a wide range of uses in the industrial sector as well as otherwise. As already mentioned the Coaxial Cables are primarily used for the transmission of signals or electrical energy from one point to the other and connect a load to the source. Some of the uses of Coaxial Cables are as follows:

• Used as a transmission line for radio frequency (RF) signals
• Used as feedlines that connect the radio transmitters as well as receivers along with their antennas
• Used in the connections of the computer networks as well as internet
• For the distribution of the cable television signals

The major advantage of using the Coaxial Cables as compared to the other types is that the signal being transmitted stays between the two conductors which ensures that there are no power losses. And when the guaranteed protection against the external electromagnetic interference is also considered, the Coaxial Cables indeed become the ideal cable to be used for the radio transmission lines.
