With the size changes of medium range voltage of wire and industrial cable, the standard chart for them changes as well.
Different types of cables are used to transmit weak, medium and strong currents.
Therefore, this product is particularly important in electrical equipment.
But what is a cable? If we were to give a general definition of this product, it should be said that a cable consists of several electrical conductors assembled in a sheath.
Cables consist of two main parts, conductors and insulators, which carry current, signals and light.
Cables are divided into different types according to voltage class, function, shape of conductors and their threads.
This product comes in many types and in many forms.
For this reason, different types of cables have different prices.
For example, the types used in telecommunications are not the same as those used to build networks.
Next, to get a more precise idea of what a cable is, we will examine the buildings that make it up.
Conductor material is one of its main components, usually made of copper.
Leaders can take different forms.
Power transfer takes place through conductors, which are usually made of copper and aluminum.
If you want the necessary wire to carry more current, use a type with conductors made of copper.
The shape of the conductors can be circular or triangular.
Besides conductors, semiconductors are also used to make electric fields uniform.
Note that not all of these types are available with semiconductors, only low voltage types.
The insulation on the conductors is usually made of plastic.
Insulators can also be of different types, depending on their application they use the appropriate type of insulator.
The sheath is also responsible for protecting the inner layer from mechanical damage.
Of course, in addition to conductors and sheaths, electrical and mechanical protection of cables is sometimes used as their other components.
Now we will check the quality of this product in terms of thickness.
The current contains millions of free electrons; as the current increases, so does the number of electrons.
In other words, the increase in current is directly related to the number of electrons.
If the desired type of cable has a larger diameter, it can carry more current, but the current density decreases with a constant intensity.
Remember, the longer they are, the more resistance they have.
In other words, the length of this product is directly related to its resistance.
Assuming that the length of this product is one meter and it has a resistance value of 4 ohms per 20 cm, then a meter length will have a resistance of 20 ohms.
Now suppose we have two meters long, in this case its resistance is 40 ohms.
