Types Of Cables And Push Pull Mechanical Controls

By Minnie Whitley


Cables, wires and other similar contraptions are a staple in the modern industrial world. There is hardly any product that does not utilize a single cable. Bikes use them for brakes, as well as cars. Even communication systems use them. You may have seen the installation of telephone and even internet cables. Television companies also utilize these in the form of network cables. All machines, big or small, have cables with Push Pull Mechanical Controls inside the vast loop of wires and such inside their hulls.

They are usually seen by the public as two smaller wires that are bonded together, either twisted or braided, to come up with a single but much more stronger one. This technique was first done by sailors. Back then, there were no big and thick ropes for use in ships and other marine vessels. To substitute for this need, they have gotten hold of the biggest ones they could find and twisted them all together, ending in a far more superior line that just fits the bill.

Since then, the use of such cables have gained popularity even in other aspects of industrial activities. In the world of heavy equipment and machinery, strong wires are made for hauling, transporting, pushing, pulling, and lifting all kinds of materials. The cords that do heavy duty work are also termed as wire ropes.

The electrical engineering discipline has had the self same idea in the form of optical wires. They are termed as such due to the multitude of optic fibers inside each casing that carry electric currents from the source to receptor. These optical wires only transmit power within a few kilometers and are useful for use in buildings and other single location powerhouses. To be able to transmit power for longer distances, power and high voltage types are used.

They are also used for networking. In areas where only one equipment is to be shared by many, twisted pairs, coaxial and fiber optics are used. These are great in work environments where people use only one scanner, fax machine, and printer to carry out individual tasks.

One type of networking cable is the twisted pair. As it name suggests, this is made up of two wires that are twisted together as one. They come in foil, unshielded, and shielded subcategories. This is used to block interferences caused by nearby pairs or other outside sources. They are essential for home and office settings.

The second classification is more or less similar as to those used in electrical engineering. The fiber optic type has a glass core center. This core is surrounded by layer after layer of protective material. The last and outermost layer is commonly made out of PVC or Teflon. It is much more expensive than the first classification, but it can effectively transmit data over longer spans due to its higher bandwidth.

There is also the coaxial classification, which people all know as the TV cable. They are extensible and can be bent at even the most odd positions. They keep electromagnetic transmissions safely within cables to assure of fast and reliable signals.

Those that are used in vehicles are termed as Bowden cable, named after a then famous brand that manufactures them. They are a staple feature in all automobile types, starting from the big and heavy ones down to the most lightweight and compact ones. They come in all kinds that are classified according to need. In fact, some manufacturers even do customized ones that adhere to client specifications.
