Data cable are the parts of a computer that provide communication between it and other hardware components . They also enable the computer to communicate with other computers. There are different companies producing data cables with different qualities. Cable handling equipment are also available.
When you want to get them, you will be required to check on some characteristics to determine their quality. The outer cover is one of the things one tests on the wires. These are the outer cover of protecting the shielding and the inner conductors. The jacket is made up of different materials that include the PVC, low smoke zero halogens (LSZH), Teflon and the plenum.
The material that is highly used in cables is the polyvinylchloride (PVC) since they are available at a lower cost. The temperatures of PVC range between -20 to 80 degrees Celsius. Teflon is the most expensive material that has excellent electrical properties that enable it to resist high heating conditions and resist chemicals. They have the temperature that ranges between -70 to 200 degrees Celsius.
The other category of materials making the cover of data cable is plenum. This material has the highest level of resistance to the flame. When combustion takes place, the material emits toxic and corrosive gasses, cables made with plenum are utilized in air circulation thus can be used in fire extinguishers in the case of fire occurrence. The temperature of plenum varies since it is made up of different materials like the PVC and Teflon.
The plenum is the other material that is highest resistant to flame although they emit corrosive and toxic gasses as combustion takes place. They are used to circulate air. Thus the fire extinguishers with plenum cables are preferred in case of fire. The goods are made from different materials like the Teflon and PVC; its temperature varies because of materials used in making them.
The other characteristic of data cables is wire size. The wires diameter in American gauge increases when the number of AWG gets the tower. These wires are known, conductors. The bundled wires in cables, wire AWG, and temperatures are the factors that affect the current capacity in the wires.
The shield option characteristics in cables are identified as the metallic layer that is placed over the conductors and under the cables jackets to prevent electrostatic between the external devices and wires that may corrupt the data being transmitted by the cables in computers. The switches, fans and motors are the external devices that cause electromagnetic interference (EMI) on the wires.
The common types of shielding of data cables are foil/mylar, foil/Mylar plus braid and spiral shields. The foil/mylar is mostly used in a printer and serial cables. They have an excellent resistance of EMI. The second type is foil/mylar plus braids also known as the double shield. They are used in fire wire, USB, and high-end serials together with the parallel cables. The products are stranded wires that are interwoven in cylindrical form. They are also excellent resistance to EMI. The third type of shield in the cables is spiral shield, it is mainly found in flexible cables they are finely stranded wires applied spirally and have excellent EMI resistance.
