Coaxial Cables

· Coaxial cables are used as a transmission line for radio frequency signals. Its applications include feed lines connecting radio transmitters and receivers with their antennas, computer network (Internet) connections, and distributing cable television signals. One advantage of coax over other types of radio transmission line is that in an ideal coaxial cable the electromagnetic field carrying the signal exists only in the space between the inner and outer conductors. This allows coaxial cable runs to be installed next to metal objects such as gutters without the power losses that occur in other types of transmission lines. Coaxial cable also provides protection of the signal from external electromagnetic interference

Technical Specification

Coaxial Cables are typically identified or classified according to its impedance or RG-type. For example, 50 or 75 ohm coax or RG-59 type coax.

A coaxial cable consists of two conductors separated by a dielectric material. The center conductor and the outer conductor, or shield, are configured in such a way that they form concentric cylinders with a common axis. Hence the term and name co-axial.

Construction features:

-Conductor material : Plain or tinned copper

-Conductor type : Solid (Class1)/Stranded(class2) - Round

-Insulation: Solid or foam polyethylene

-Shield: Tinned or plain copper braided

- Outer sheath: Polyvinyl chloride (PVC) or Polyethylene (PE)

Other features :

-Ultra violet (UV) resistant colored outer sheath

-Low smoke and fume (LSF)

-Halogen free and flame retardant (HFFR)

- Oil & hydrocarbon resistant

-Vermin proof

Standards : JIS C-3501, MIL-C-17, IEC 60096 , ISIRI 1311

Note : Armoured or lead sheathed cables and also cable with extra shield are available on request .
