Design Layout and Installation Methodology of Cable Trays in a Distribution Substation of Pakistan

The purpose of our research work is to provide a design layout, installation method and protection system for cables and wires through cable tray/ladder supporting system in electric power generating, transmitting and distribution stations. This system provides different methods of laying cables on cable trays and supporting channels, which make it easy for cables to run between different electrical equipment and provide physical protection to the cables. The main objective of the proposed research work is to minimize premature cable failures and their consequences. It is found that majority of cable failures in a substation are result of poor layout of cable termination and mechanical damage during cable installation. No one-cable characteristics should be emphasized to the serious detriment of others. To achieve sound cable system, it is necessary to provide good practices of design, construction and installation as well as balanced characteristics of cables. The possibilities of electrical failure can be reduced by implementing proposed method. The proposed work provides guidance for cable termination, cable routing and good practice of cable installation system in substation, which can also utilize in commercial applications.
