Getting to know the world of electric wires and cables

Today, electricity is known as the most influential energy in our daily life. From the lighting
 of houses and streets to the movement of electrical and industrial equipment, everyone depends
 on electric current.  But this vital flow will never reach its destination without wires and cables.

Electric wires and cables are the vital vessels of electrical systems that direct electric current 
from the place of production to the place of consumption.  The variety of these wires and cables
 is so great that choosing the right type for each application can be challenging.

In this article, we will review electrical wires and cables, their different types and categories,
 as well as the points that should be considered in choosing the right wire and cable.
 The purpose of this article is to provide you with comprehensive and practical information 
so that you can choose the right wire and cable for your needs with complete knowledge.

What is the difference between electric wires and cables?

In the complex world of electrical installations, it is often difficult to distinguish between electrical
 wires and cables.  Both play a vital role in the transmission of electrical current, but there are 
subtle differences in their structure, application, and performance that are essential to understanding
 in order to correctly select the right type for each project.

Wire: Consists of a conductive conductor (usually copper or aluminum) covered with an insulator.
  This insulation can be made of PVC, rubber or fireproof materials.  Wires are suitable for
 mobile use and short distances due to their high flexibility.
Cable: consists of several strands of insulated conductor wires placed next to each other and
 surrounded by a protective sheath.  This sheath can be made of PVC, rubber, metal or fireproof
 material. Due to their high strength and resistance, the cables are used for fixed purposes and long distances.

 Structure:

Application:
the wire:
Building wiring
Connecting wires of electrical appliances
Wires of engines and generators
Internal connections of electrical panels
cable:
Low, medium and strong power transmission lines
Industrial wiring
Underground and aerial cables
Connections between electrical equipment
Important Notes:

Size: wires and cables are produced in different sizes according to the capacity of passing current.
 Choosing the right size for each application is a necessary process to avoid overheating
 and potential hazards.
Voltage: Wires and cables are designed for different voltages (weak, medium and strong pressure).
 Using wire or cable with improper voltage can lead to damage and life risks.
Environment: Wires and cables must be selected according to environmental conditions 
(humidity, temperature, chemicals). In fact, proper insulation and sheathing ensure that the
 wire or cable is resistant to external factors.
