Wires, filaments, cords, cables and other similar kinds are common to everyone. They are perhaps the most popular tools that everyone is familiar with them. Today, there is no machine that does not utilize this contraption. It is found in simple and ordinary things that an individual uses everyday like the television, the telephone, even in bikes and cars. They are also used in special machines one does not use nor see on a regular basis. Big vehicles and equipment have bigger wires and Push Pull Mechanical Controls to support them.
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.
Networking cables, on the other hand, are essential tools in places where people share a single device. Most offices and schools have these which are used to connect two or more computers to share a printer, a scanner, and other devices. This classification is composed of many types, among which are the twisted pair, the optical, and coaxial cables.
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.
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.
