Cable Laying or Installation
Laying or installing cables is one of the more essential aspects in the construction and industrial sector, ensuring that telecommunications and electrical power will be existent for later use by its consumers.
However complex it may seem, the process of cable-laying is basically a simple one. It simply consists of putting the cables in strategic areas in the building or structure, making sure that they are secure, obscure and aesthetically situated. For industrial or commercial purposes, cable-laying can be far more complicated, but the same basic principles are still followed.
Cable-laying used to be monopolised by telecommunications and electrical power companies. In the present time, apart from the previous ways cables were used, cable TV networks, internet service providers, cellphone companies and other similar businesses are now scrambling to get a piece of the pie, just to ensure consumer subscription and to gain more profit.
Short History of Cable-Laying
The history of cable laying is fascinating, and short of a miracle. Initially, cables were made to carry only electric current. Electricity was discovered earlier than the telephone, but the use of wires was adopted later on for the purpose of telecommunication. It is actually a known fact that telephones also make use of a low electric voltage to make it operate properly.
Electricity could be sourced locally, but communicating with different continents used to be an impossible feat, hence the demand for more inventions and discoveries related to wired communication. With the growing need for electricity and telephones during the earlier times, the demand for more and more efficient and evolving cable types also correspondingly increased.
It was, in fact, a big milestone in telecommunications when cable-laying significantly reduced the communication time between North America and Europe, from 10 days to just a few minutes, because of the so-called Transatlantic Telegraph Cable. The default communication mode used to be done using messages sent through a ship. From then on, communication has continually improved and developed up to what it is today.
Different Types for Different Purposes
Electrical cables come in different types. Cable-laying or installation in a residential structure requires only the regular type of wiring for this purpose. For the more specialised electrical power transmissions for bigger industries, the high-voltage cable, power cable, and the high-voltage direct current are commonly used.
Telecommunication cables, likewise, come in varied shapes and sizes. Their main purpose is to transfer signals and connect them through wires or cables. Some known types are called co-axial cables, fiber optic cables, twisted cables, Ethernet crossover cable, etc. These wiring systems are commonly used interchangeably for telephone lines, internet network connections, LAN connections, cable TV and for similar purposes.
Undersea cable-laying is the highly-specialised type of technology that was used in putting the Transatlantic Telegraph Cable in place. A huge ship was used in doing this, with the long cable gradually laid from the point of origin to its point of destination.
At present, there are a lot of ways cable-laying is done, underground, above-ground or under the sea. More advanced methods and technologies are now being used to make this task more efficient yet effective.
There are plenty of opportunities to enter the industry as long as you have the training, certification, or required degree as a network cabling installer, network cabling designer, data-communications cabling or cable installation.
