It is a cord that serves as a conductor, more or less thick, which is created by several threads, covered by some material that serves as a protector and insulator, which is divided into several types, which have different uses, which in turn, give various meanings to the term "cable".
The most popular or the main use of the cable is given in electricity. The electric cable is made of several interlaced wires, commonly made of copper (due to its effectiveness to serve as a conductor) or aluminum (due to the low production costs compared to copper, but it is less effective in terms of conductivity). It is commonly covered by plastic, which serves as an insulator, which varies in type and thickness according to the voltage level handled by the cable, the nominal current, the ambient temperature and the conductor's service temperature.
The electrical cable is composed of the conductor, the insulation or insulator, the filling layer and the jacket. Furthermore, it can be divided according to: its voltage level, components, number of conductors, materials used, conductor flexibility and conductor insulation.
On the other hand, there is the coaxial cable, which is one that is composed of two concentric conductors: the live or central conductor (which is dedicated to transporting the data) and the outer conductor, also called shielding or mesh (acts as the return of the current and is ground reference). These conductors are separated by an insulating layer, known as the dielectric. These types of cables can carry high frequency electrical signals.
In Latin America and Spanish speakers, a new use for the term cable has developed in recent times, which has been used to represent the television service that is not transmitted over the air through a receiving antenna, but rather arrives by cable., a service commonly offered by private companies, which means that users must pay a monthly fee to enjoy it.
Finally, there is a phrase that is used as an idiom in many countries, which says "the cables crossed", which refers to a person losing control of their actions at a certain time. Also, there are countries where “throwing a cable” means helping someone in need, in a situation of trouble.
