Electrical cable - The messengers of electricityby Pooja Late so cut
Nobody has seen the invisible power that drives all the machinery. All that we have seen are just the switch and the light, a switch and the spin. But what are these invisible things that drive our day to day life itself? These invisible power people are the moving electrons. Electricity is nothing but electrons in motion causing electromagnetic fields which in turn produce current. This simple principle is a great power that is driving the world invisibly because great and important things are invisible.
The invisible drivers and their vehicles
As said above the motion of the electrons produce current. This needs a path, doesn't it? The path is given through materials called conductors. Conductors are substances that are capable of passing the electrons through them. Not all materials are conductors. Some don’t allow passage these are non-conductors. These are wood, paper rubber etc.
Electrical cables are conductors that are made up of elements that have a high potential to conduct electricity. These are mainly made up of copper, aluminium, iron. these metals show high potential for electrical conductivity. Hence these materials are used in electrical cables.
Where do they play their part?
These electrical cables are used almost everywhere. If we take a look around everything is connected and they are connected using electrical cables.
They are the messengers of electricity. They carry the charges from one place to another. Whenever light is switched on or a television is turned on the circuit is closed and the charges start to flow through the circuit. That's how the appliances we see everyday run on electricity.
Types of electric cables or the messengers of current
There are numerous types of electrical cables now evolved. These cables have different potential and are differently abled carriers by themselves. Some carry more current while some carry less. Some can transmit electricity over large distances while some can transmit over short distances only.
Some cable types are different from others in terms of their amount of protection given to them because they travel underground or above in the open air. These cables need extra covering and protection to avoid any wastage of electricity.
· Coaxial cables or coax electrical cables
· Twisted pair electrical cables
· Optical cables ( modern and extensively used )
These are the common types of electrical cables that are widely used nowadays everywhere.
Cables also carry codes and colour schemes which make them more specific and easy to classify.
Choosing the right messengers
When it comes to electricity choosing the correct cable is like choosing between life choices. Electricity is sometimes dangerous when left unattended or leaked. There are various cases of accidents due to electricity. The main reasons would be the leakage of current due to improper cables. When these cables are unknowingly touched they transfer the electricity through the body causing the person to be electrocuted. There is also fire accident cases recorded due to a spark of current that burns everything down.
Hence to avoid these accidents one should choose the proper and good quality electrical cables.
· Know the purpose of the cable. If it is a house wiring cable then a twisted pair can be used. If it is a long distance transmission then an optical fibre cable can be used.
· Check its efficiency. Checking it at the retail store before buying it is important.
· Check for damages or ruptures
· Maintain or change cables at regular intervals.
If approached properly and maintained well these messengers will work diligently for a long time and offer good service and safe electricity transfer.
