Types Of Cables And Push Pull Mechanical Controls

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.

A cable is most often composed of two or more wires that are twisted, bonded, or braided to form one thick assembly. These wires are then covered in a special casing which is more often made of water proof material. They were originally used in the nautical field, where sailors shackle their ropes together to form one strong nautical line.

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.

Electrical engineers borrowed the idea from old sailors to come up with a tool of their own. These came to be known as optical cables. The name is obviously derived from the optic fibers inside each wire. These fibers are highly receptive to and can transmit electric signals within a short distances between the origin to recipient. These are not advisable for power transmission for longer gaps than a few kilometers. For such cases, power suppliers make use of a high voltage cable or a special power line.

There are also those used in networking. If more people has to share a single device, say, a printer for printing office memos, a special cable is used. Obviously, this type is most used in offices, libraries, and other areas that house quite a number of computers which will share only one scanner, fax machine, and the like.

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.

The coaxial type is made primarily to confine the electromagnetic waves strictly within the cable. This type has a more flexible body that can be twisted to different angles. This is the most common wire for television connections.

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.
