The configuration of coaxial cables makes it a good conductor of electricity. Its innermost core is made up of Silver Plated Copper(SPC), Silver Copper Clad Steel (SCCS) or Copper. The reason behind using these conductors metal is its high electrical conductivity. This innermost conductor is surrounded by a high quality fluoroplastic dielectric insulator (PTFE) which reduces the signal loss to minimum. Hence, signal is transmitted with fewer disturbances.
Next layer in the composition is the Silver Plated Copper (SPC) or Copper shield which surrounds the insulator. This shields the insulator and does not allow the electrical and magnetic lines to enter the cable and in case of leakage of these signals, this shield does not let these signals to transcend the range of dielectric insulator. This renders the transmission of weak signals. The outermost layer is plastic sheath which is called jacket. This jacket protects or shields the internal structure from the environmental factors like sunlight, chemical reaction, temperature variations etc. and provides strength to cable. This jacket is usually made up of Poly Tetra Fluoro Ethylene (PTFE) or Polyvinyl Chloride (PVC) or any other insulating material.
The flexibility and conductivity of coaxial cables have widened its area of application. These cables are brought in use in the transmission of video and radio signals. Feed line is the example in this context. Feed line works as a bridge or connector between the antenna and the receiver of radio and transports the Radio Frequency Current from receiver to antenna.
Coaxial Cable can withstand all kinds of weather conditions ensuring that there is no power loss. It facilitates smooth and disturbance-free telephonic conversations as it does not allow signal power loss. It can be concluded that due to its various characteristics, coaxial cable finds its applications in many industries like telephone, TV, airline, radar, computer networks, etc.
We are manufacturing RF cables like RG 187, RG 188, RG 195, RG 196, RG 393, RG 400 etc. as well as cables as per customer specification and requirement.
