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.

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.

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.

Twisted cables are composed of two wires that are tangled together. These two wires, the forward and return conductors, respectively, are tangled so that they effectively obstruct annoying interference from other origins that may affect its effectiveness. They also come in shielded, foil, and unshielded types.

Another type is the fiber optic. It can transmit faster and larger data and is obviously more expensive among all the other types. It has a special glass core that is shielded by thick layers of protective casing. Teflon and PVC are perfect casing materials for this type.

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.

Push pull controls are also known as Bowden cables, named after the man who first thought of making them. They are found in every type of automobile, from bikes to loaders and other huge vehicles. They transmit force without requiring much too much effort from the operator. These can even be modified and custom made to suit every type of need.
