In 1752, Benjamin Franklin, one of the pioneers in the study of electricity, He performed his famous kite experiment during a storm, proving that lightning is a form of electricity. This discovery was crucial to understanding the nature of electricity and paved the way for later experiments related to the conduction of electricity..
Alessandro Volta and the Electric Battery (1800)
In 1800, Italian physicist Alessandro Volta invented the first electric battery, known as the dick back. This battery was the first direct current generator (DC), providing the basis for later development cables capable of conducting this electricity in a controlled and efficient manner.
Michael Faraday and Electromagnetic Induction (1831)
In 1831, Michael Faraday discovered the phenomenon of electromagnetic induction, which made it possible to generate electric current by moving a conductor through a magnetic field. This principle is fundamental in the creation of generators and transformers, systems that would use cables to distribute the electricity generated.
2. The Industrial Revolution: The Birth of Electrical Wiring
With the beginning of the Industrial Revolution at the end of the 19th century, electricity began to be a resource used in factories, offices and homes, which prompted the need for cables to distribute it efficiently. Advances in the science of electricity allowed the creation of the first electrical wiring systems, fundamental for the electrification of cities.
The Invention of the Light Bulb and Copper Wiring (1879)
In 1879, Thomas Edison invented the incandescent light bulb, which marked a before and after in the history of electricity. To power the light bulbs, Edison developed an electricity distribution system that used copper cables to bring electricity to homes and businesses. This was the first time that a cable system was implemented as basic infrastructure for energy transmission..
The War of the Currents: Edison vs. Westinghouse (1880s)
In the famous “War of the Currents” between Thomas Edison and George Westinghouse, It was debated whether direct current (DC) or alternating current (AC) It would be more efficient for the transmission of electricity. Although Edison defended the use of direct current and copper cables for transmission, It was the alternating current proposed by Westinghouse and Nikola Tesla that turned out to be most effective, especially for long distances. This event spurred the expansion of the cables high voltage for the transport of electricity.
3. The 20th Century: Electrical Cable Expansion and Improvements
With the widespread use of electricity throughout the 20th century, electrical wiring experienced great advances. As cities grew and energy demand increased, cables had to evolve to withstand higher loads, longer distances and better safety conditions.
The High Tension Cable (1910-1920)
During the first decades of the 20th century, electricity transmission capacity was a key issue. Los high tension cables began to play a fundamental role in long-distance electricity distribution. These cables, initially manufactured with copper, They were covered with insulating materials such as asphalt and rubber, which allowed them to transport electricity without significant losses.
Underground Cable and the Use of Improved Materials (1930-1950)
In the decades of 1930 y 1940, Cities began to replace overhead cables by underground cables, which offered better aesthetics and greater safety. These underground cables began to use insulation materials such as polyethylene and the PVC (polyvinyl chloride), which allowed improving the durability and resistance of electrical systems, especially in urban environments.
Fiber Optic Cable (1970s)
At the end of the decade of 1970, The field of telecommunications experienced a revolutionary change with the development of fiber optic cables. Although they were initially used to transmit information, Fiber optic cables also began to have applications in electricity distribution., as they could handle data efficiently and quickly over great distances.
