What is an Electrical Cable?
The electrical cables are the medium by which they distribute and transmit electrical power at different destinations. These cables are capable of transmitting high voltage to various connected destinations. The cable is used for the distribution and the transmission of the electrical cable where overhead lines are impractical to use. Cables are generally made using copper as it is a good conductor of electricity. Copper is easily available but sometimes aluminum is also used in cable as it is more cheaper than copper and a good conductor.
An electrical cable is generally composed of three things:-
- Conductor : It is used for transmitting electricity. The most commonly used conductors are copper and aluminum. The conductor in the wire provides the conducting path to the cables.
- Dielectric : For isolating the conductor from other things and preventing it from an unintended path. Different synthetic polymers are used for insulation. The dielectric (insulation ) withstands the voltage and it isolates the conductor to come in contact with another object.
- Sheath : It is a protection layer to the wires from external influence or atmosphere. commonly used sheath material is PVC. The sheath protects the cable from external influences like human touch, water spills, chemicals, etc.
Electrical Cable
Electrical cables are used in every sector which are used in transporting electrical energy from one point to another. These cables are composed of materials that are electrically conducting with an outer insulating cover. When the cables are connected to the corrected terminal of the the application allows them to carry the power or current into them. These cables are used for the distribution of electrical power to various destinations. They transmit high-voltage power where the overhead lines are impractical to use and implement. There purpose of electrical cables is to transport the electrical energy from one point to another destination. The electrical cables are an assembly of one or more wires that are twisted with each other and are used as conductors for carrying electrical current. These cables can have different configurations based on their design on national and international regulations.
