An Electrical Cable is used to transmit electrical power from one point to another. It carries power and is major necessity for running electrical devices. Also known as power cables, Electrical Cables are widely used in almost every industry. They are comprised of electric wires which are usually made of copper. The Electrical Cables are insulated in order to get protection against shocks and hazards. There are many types of electrical cables in terms of configuration, size and performance. Each one of them is suitable for specific applications. Below mentioned are some of the common types of Electrical Cables
A coaxial electrical cable is comprised of a copper plated core which is surrounded by a dielectric insulator. A woven shield of copper enwraps the insulating layer which is enveloped by an outer layering of plastic sheath. Coaxial cables come in different sizes, and performance parameters. They can be further classified on the basis of malleability, power handling strength and cost. They are commonly used at residential places to connect devices like televisions, radios with power source. They are also used to facilitate television networks and local area networks.Shielded Cable
A shielded electrical cable is composed of collectively enclosed insulated wires. Mylar foil or woven braid shielding could be used for adjoining the wires together. High-voltage power applications generally use shielded cables. Shielded cables are capable of providing uninterrupted supply of power or signal as they are resistant to external radio or power frequency interference.
Apart from the above mentioned types of Electrical Cables, Aerial Bunched Cables, Jelly Filled Telephone Cables and Thermocouple Cables are also commonly used for specific purposes. Electrical Cables are designed in such a way that they can withstand harsh weather conditions and exposure to rains or sun.
