These conductor in form of a stranded wire which are insulated with a polymer (non-conductive) coating is a wire while a cable is combination of two or more shielded wired with a single cover which is used for generation, distribution and transmission of electrical power. A wire is designed with a single electrical conductor whereas an electrical cable is designed with several wires in a common sheathing but both of them are used to carry electrical current. Wire gauge is the most common measurement of the size, either diameter or cross-sectional area, of a wire. In the US, the most commonly used wire gauge system is AWG, or American Wire Gauge. In the computer, there are different parts available which are connected directly otherwise uses different cables for connecting from parts of the computer to the system. These electrical cables are used in outdoor or underground applications. Ques: Mention properties of cables suitable to be laid underground? 3. If selecting a cable for a special application such as outdoor or underground use, make sure you select the right type of cable.
The type of cables are used in the instrument equipment such as transmitters, sensors and switches. From that moment, Europe and the United States experienced accelerated development, and in a few decades almost all the main cities of each country had telegraph cables. In the current where every where it is a web of wires and cables at every place the cables play a very vital role in transmission and distribution of electrical power. These are very important for various application like power generation, distribution and transmission. These are generally made of polymeric material and these are used according the the environment conditions. Shielding or Armor : It is the external protection of the conductor against the temperature, sun, rain etc. These are generally made of polymeric material. Protection or Outer Sheath : In current time every cable have an outer sheath is used of protecting the cable. Sheath: Sheath is an additional layer that gives protection to the wires in the cable from the atmosphere & chemical reactions. They are also insulated with insulating material to prevent them from exposing them to atmosphere.
The insulation are made of polymer, plastic layer that cover the conductor it from external contacts. The major components of this cable are glass or plastic strands. Generally, a cable includes three essential components like conductor, insulator, and sheath. A common material like polyvinyl chloride (PVC) is used for the sheath. Some of the common labels written on cables are THHN, THWN, THW & XHHN. Why we use shielded cables ? Applications prone to moisture contact or pressure use cord grips with synthetic rubber or other elastomer seals. A cable plug or cord that transmits data or power to different devices is known as a computer cable. The name couldn’t be more appropriate: you simply plug in and charge. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. In case your auto battery has totally lost its charge, you can charge it utilizing a car battery charger. These cables are available in small size but we can extend by using some adapters based on the requirement. Different types of cables are used at different requirement like Coaxial cables, twisted cable pair cables, etc. The color codes on the electrical cables help to identify their purpose of usage and helps in proper operation and installation.
The power cables are used for domestic purpose as they can be buries into the ground or can be used overhead. These cables are mainly used for high voltages transmission in locations where overhead lines are not practical to use. We use shielded cables used when there is some unwanted electrical noise or some electromagnetic interference that the transmission of power. Overall the electrical cables are important for efficiently transportation of electrical power in every sectors. In electrical and electronic circuits, electrical cables are connected by using connectors which are known as cable assembly. Strength and flexibility : The cables which are used for any purpose must have a large insulation and should be easily installed. Circuits supplying a kitchen must not be used to supply any other area. For domestic Premises, all wiring supplying one room must be on the same phase, other than for kitchens and for ceiling lighting.
