Electrical cables apart from being just providing cable connections have tremendous control over the applications. Some cables can only provide power to the application and some can only be used for data transmission. Two important aspects of the electrical cables will be discussed as follows.
Power cables are generally referring to those electrical cables that have the strength and capacity to transfer high power transfer at large distance. Mostly used in the cases to provide power to the devices like motors, industrial machines, overhead and underground power transmission. Power cables are also used in power generating plant e.g. Solar plant, Wind Plant, hydro energy plant.
Communication cables are generally referring to those electrical cables that have the capacity to transfer low voltage signal transmission with minimum attenuation. These cables are used to convey information in the form of electrical pulses. Electrical pulses contain the electrical signal in the form of digital data which comprises of fewer millivolts. Communication cables are used in testing and measuring instruments. Dealing with the applications where the signal conditioning needs to be very precise the communication cables lay their major emphasis on signal integrity. A further application that involves the use of communication cables is electronic devices like intercoms, data transmitting devices, electronic circuits, and much other radio frequency related devices.
Power and Communication Cables
Nowadays, electronics and electrical engineer work side by side to collaborate both power and communication cable into one hybrid cable. Communication and power transfer using a single cable are old, but the applications are still very few. However, engineers are still working on this idea to expand the capabilities of this hybrid cables even in remote applications like in broadcasting units, antenna, and wireless applications.
