The Power cable is the key element of new generation Power distribution network. Wire and cables plays an important part in our surrounding. A cable is two or more wires running side by side and bonded, twisted or braided together to form a single assembly. In mechanics cables, otherwise known as wire ropes, are used for lifting, hauling and towing or conveying force through tension. In electrical engineering cables used to carry electric currents. An optical cable contains one or more optical fibers in a protective jacket that supports the fibers. Essential power cables used for transmission and distribution purposes consist of conductors stranded from plain high conductively annealed copper wires insulated with oil-impregnated paper tapes. The single or multicores assemble in them enclosed in an impermeable metal sheath, and where necessary depending on installation conditions, the assembly is protected by steel armoring. Modern cable technology is still pursuing the above ideal, but today many other additional factors have also to be considered, as indicated in the following notes (dealing with oil impregnated paper insulated cables), which are divided into three main parts, the first dealing with cable design, the second part outlines modern manufacturing methods and the third section discusses installation requirements. To the electrical industry faced with the continuing and probably inevitable increase in the cost of copper, the economic factor has necessarily been of vital importance. The Indian Cable Industry already has Co-operated readily with Government and the electric power industry in the country in producing aluminium- conductor insulated power cables. They have also established elaborate training facilities for wiremen and electricians in the jointing and installation of aluminium cables. The switch-over to aluminium for power and house-wiring cables in India has been dictated mainly from the point of view of availability and the difficult foreign exchange situation now prevailing. However, when free market conditions resume and when copper becomes freely available either from imports or by exploitation of indigenous copper ore reserves, the cable industry expects that a fair share or such copper will be allocated to it and the electric power industry in adequate quantities so that copper or aluminium could be used in cables to suit customer preference, technical requirements and real economics. The selection process of power cables is almost the same as that of a bus system. The basic data for selection would suffice the majority of applications. For site conditions and lying arrangements, which may influence the basic rating of a cable, corresponding daerating factors is also indicated. The information covered for the users to select their cable requirements. PVC coated cables and wires are extensively used in all electrical linings, domestic lightings and all other purposes. Parkway lighting, river crossings, and lighting of the grounds of an institution are among the more common applications of armoured cable. According to the present policy of the India Government, this time, PVC coating on electric cables and wire is exclusively reserved for development in small scale sector or in the cottage industries. Power cables play a small but significant part in infrastructure activities. With strong investments proposed across sectors such as power, realty, industrial and telecom, the cable industry in India is slated for a strong growth going forward. In India, the underground electricity distribution networks are rapidly undergoing upgrades to meet the growing requirements of quality power for industrial and residential use. There are also increasing trends of converting the overhead line to underground cables in low tension (LT) & high tension (HT) network in urban distribution networks. The demand for PVC coated electrical wires (with the rapid electrification all over the country) is increasing at a rapid rate. Hence there is a bright scope for starting new units in this field.
