Cables lay the path for transferring the electrical signal from one place to another. Every cable has certain qualities and certain limitations. Electrical cables can be classified on the basis of their length, dimension, type, current capacity, and shape. Some electrical cables have the ability to transfer high voltage current, whereas some are just used for transferring very small minute micro signals. All of these are relevant to their applications and the environment in which they are being installed.

Some of the classification of these electrical Cables are as follows:

electrical-cablesCo-axial Cable

One of the most commonly used electrical cables is the co-axial cable also called as coax. In this type of cable, the inner conductor has a tube-shaped covering of the insulating medium on it. This insulating material is covered with a conducting shield. Both the inner conductor and insulating material share a geometrical axis that is the reason this cable is called co-axial cable. 

Direct-Buried Cable

electrical-cables-02Some electrical cables are designed to be buried under the ground without any excessive protecting material on it. The insulation has been specifically designed in a way to tackle heat, moisture, conductivity and soil acidity. It contains an inner and outer sheath, shock absorbing gel and filler armor so that the cable has the strength of transmitting the signal even after being buried underground.

Continuous-flex Cables

electrical-cables-03Deformation among the electrical cables does damage the inner conductor and signal quality. In automation industry, the cables have to be flexible as most often it is being subjected to a lot of turns inside a machine. For that reason, continuous-flex cable or flexible cable are used. It contains multiple bundling of the conductors which provides flexibility in its structure and keeps the electrical cable stable under maximum bending stress.

Heliax Cable

electrical-cables-04This is a semi-flexible electrical cable, which consists of a grooving outer conductor and an inner conductor, air as a dielectric medium as an insulation. Some of these cables also come with outer jackets for outdoor protection.
