Power Cable Light Your Surroundingsby India Internet Business Services
Power cable is a assembly of two or more electric conductors used for transmission of electric powers. There are number of ways for installing like permanent wiring within the buildings, run overhead or exposed and buried in the ground. It is a line used to distribute electricity.
It comes in a variety of materials, sizes and types. In industry, sometimes the large single insulated conductors are also called power cables.
A cable has three important components conductor, insulation, protective jacket. Make up of individual cables varies from application to application. Stranded copper and aluminum conductors are used by power cables, although small cable powers may demand solid conductors.
Choosing a adequate cable or wire for any purpose is very important. Different appliance requires different voltage and current to operate. So different cables should be required for different devices.
There are some points one must take into consideration while selecting cable.
Types Of Installation
The method of installing a task is an important factor for selecting cable. You may use it in underground application, indoor or outdoor application. The requirement of cable vary as the application vary. One must give attention to the type of application using.
Ampere capacity Requirement
The Ampere capacity of KVA loading is required to determine the final conductor size. Before finalizing the size of the conductor, one should be aware about the current load, power factor and KVA load. Voltage drop determines the cable size rather than by heating.
For buying the proper cable, the voltage determination is necessary for the electrical device. The voltage factor determines the type and thickness of insulation.
It includes the external thermal conditions responsible for measuring the raised temperature of a cable. Lasting and proper functioning of cables are affected by the external factors.
Presence of Artificial Cooling, Ambient Temperature, Number of Cables in a Duct Bank, Depth of Buried Cable, Nature of Surrounding Atmosphere, Proximity to other Cables, Thermal Conductivity of Soil or other Surrounding Medium are some of the important factors affecting the selection of cables.
Other than the above mentioned conditions and situations there exist some more special conditions affecting the performance of the cable. These conditions should also be considered for better life of your cables. Some of those conditions are effect of magnetic material like pipes, noise or interference occurring in telephone cables and many more.
There are so many electric cable manufacturers in the market offering a wide range of cable accessories. Cable connectors, cable joints, cable cabinets, cable terminations are few such examples.
