Transmission of electricity with high voltage
Transmission of electricity with high voltage
Some may understand why the voltage output from the generation stations is raised through transformers and transported through transmission lines over long distances until it reaches the final consumer .
But what may be a problem for some is to imagine this matter , so how do we transfer the same electrical energy with different efforts or different currents each time
To bring the matter closer to the imagination of the human mind , it can be imagined that the generation stations are reservoirs of water , and this water is pumped to long distances .
There are two ways for us . As for transporting water at medium pressure in huge quantities through huge pipes with a large cross- sectional area , and therefore its prices will be expensive .
Or transferring the same amount of water , but by pumping it with high- pressure pumps through pipes with an inverted sectional area , and thus a lower cost .
Because we are in any project that must have an economic feasibility , so what is the point of delivering huge quantities of water in a very expensive way, the final consumer may not be able to pay for the delivery of this water
Likewise , electric power , the efforts are raised at the beginning of the transmission lines ( similar to pumping water through high pressure ) and this is a benefit as the electric current will decrease in the transmission lines , thus reducing the area of the wire section and reducing the size of the towers that will carry it .. and thus raising the economic feasibility of transferring energy
Transmission of electrical energy at low pressure and small quantities in the wires is completely equal to the transmission of high currents at medium or low pressure , but raising the efforts is much more economical than using transmission lines with high amperage capacities .
In addition , reducing the currents in the transmission lines will bring us other benefits that accrue positively to the economic feasibility , as reducing the currents reduces the ohmic losses that must not be exceeded by certain percentages of the transmitted energy according to international standards .

Among the most prominent features of the site, we find that there is proportional prices. On the Jazli website, you do not have to worry about the imaginary prices of products, as is the case with most sites that display their products on the Internet.
The price of product delivery is very reasonable and not expensive, just as the site accepts delivery to various countries, without forgetting that it accepts free shipping on some products.
Among the advantages of the site, we also find that there is the high quality of its products, as it is impossible to find a poor-quality product. Rather, the Jahzli website deals with major companies, Philips, for example, and other famous brands, so you have to remove from your mind the idea of poor quality of one of the products. Also, one of the advantages of the site is that it does not specialize in one type of product, but rather you will find various types of products on it, for example, electrical appliances, hand tools, mechanical devices, paints, packages for establishing apartments and many other types.
Jahzli also accepts what is known as the shopping cart, which makes it easier for you to filter the products you want to buy and put them in one package in order to be able to pay with the click of a single button.
Multiple payment methods are accepted.
