Types of Cables

Types of Cables

Various types of Cables are used everywhere for various applications. Not all cables perform the same application. The function of a cable depends upon the type of cable. The electrical cables are made of aluminium or copper wires protected by a insulating coating which can be made of synthetic polymers.

Cables are classified into 5 types depending upon their purpose:

  • Ribbon Electric Cables
  • Shielded Cables
  • Twisted Pair Cables
  • Coaxial Cables
  • Fibre Optics Cable

Ribbon Electric Cables

It consists of multiple insulated wires running parallely with one another and are used for transmission of multiple data simultaneously. For example, this is used to connect the CPU with the motherboard and are generally used for interconnection of networking devices.

Shielded Cables

It consists of 1 or 2 insulated wires which is covered by woven braided shield or aluminium Mylar foil for better signal transmission and removing irregularities in the frequency of power and external interference in radio. These cables transmit high voltage electric current and are protected by a shield.

Twisted Pair Cables

It has two or more insulated copper wires which are twisted with each other and are colour coded. This type of wires are usually used in telephone cables and the resistance to external interference can be measured by the number of wires.

Coaxial Cables

This consists of solid copper or steel conductor plated with copper which is enclosed in metallic braid and metallic tape. This is entirely covered with insulated protective outer jacket. These type of cables is used for computer networking and audio-video networking.

Fibre Optics Cable

There are these types of cable which transports optical data signals from an attached light source to the receiving device. We are pretty much aware of what is optical fibre and its uses in wide variety of applications.
