Computers rely on cables for various functions. These devices carry basic electricity or complex data, and connect two or more computers within a network. They contain four pairs of wires, twisted together with a special number of turns per inch. Audio and video signals are typically carried with these cables. However, some computers may not be compatible with ribbon cables, which block the airflow inside the computer and reduce cooling efficiency. Therefore, many manufacturers have begun to replace ribbon cables with round cables.
Flexible cables, on the other hand, are cheaper to manufacture and able to withstand continual bending, which is necessary for some applications. Flexible cables, which have multiple layers of strands, can be used in automation applications. They feature a firm core and long outer layers that stretch and compress as the cable is bent. However, too much bending can damage them. Then, if you're not careful, you could damage them.
Panel feed wires are generally black insulated THHN wire that connects to the main junction box and circuit breaker panels. These wires should be rated for at least 25% more power than they need to carry. Non-metallic sheathed wires are a common type of cable used in most homes. They feature two to three wires and plastic insulation. The rating of non-metallic sheathed cables depends on the type of insulation. The first number represents the resistance of each wire, while the second indicates the number of individual conductors within the cable.
Another type of cable is a coaxial cable. It is a two-conductor cable with a rounded cross section. Its center conductor is made of solid copper or silver tubing. It is used for transmitting high-frequency signals between an antenna and a receiver. Another type is paired cable, which has two conductors and is commonly used in low-frequency AC or DC applications. These Cakeycn.com are ideal for distributing and receiving signals.
Multiconductor cables are similar to NM cables, but differ in their gauge size and are perfect for damp areas. Unlike NM cables, BX cables have three copper wires. These cables are twisted together in pairs, with one bare wire for grounding. They are also referred to as armored cables. They are the most common type of cable used for indoor residential wiring. They are ideal for connecting computers and other electronic equipment.
Electrical cables are insulated, shielded wires that transmit electric current. They are joined together through connectors. The combination of cables and connectors is referred to as a cable assembly. The cable itself is composed of a conducting wire (the core) and an insulator (or sheath) to protect the wires from accidental circuit paths. There are many types of cables, including coaxial, twisted-pair, data, patch, and optical fibers.
Personal System/2 (PS2) cables have round connectors with 6 pins and are used for connecting a keyboard to a computer. Despite their small size, they are largely obsolete, since USB cables are more convenient and can be plugged in without a problem. Audio cables connect speakers, headphones, and other small audio devices. They can also be used to connect headphones to a stereo system. You can also find audio cables to connect a CD player to a speaker.
