Push Pull Mechanical Controls And Other Cables

By Minnie Whitley


Cords and similar looking tools are a common sight. They can be found everywhere. They are inside homes in the form of television, internet, and telephone cords. They are found at the office or at school in the form of networking cables. They are found in power lines. They are even in cars and vans and bikes with Push Pull Mechanical Controls.

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.

Now, the use of a cable is not limited only for use in marine vessels. They are used in almost everything, more so in the field of heavy equipment. Here, they are used to transport, haul, pull, push, and lift things to wherever the operator pleases. The cables that are utilized in this line opf work are more commonly known 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 fiber optic cable is the most expensive among networking kinds. They are perfect in thje transmission of relatively large data in the least time possible. This efficiency is due to the glass core inside each wire, swathed in safeguarding layers of PVC and Teflon.

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.

There are also cables in various land vehicles. They are found at the brakes of a bike to the cords in a hauler. They come in all appearances to fit all types of need. Manufacturers even make special ones that adhere to the request of the costumer to ensure optimum satisfaction.
