Instructional design of multi-layer insulation of power cables

An instructional procedure is described for designing an electrical power voltage distribution cable to satisfy the engineering requirements of maximum insulation utilization, maximum load current, and minimum outside diameter of the cable. The student in this project practices many engineering principles such as insulation coordination, current carrying capacity requirements, calculation of cable losses, and the use of the optimization technique. The engineering student is guided to develop a criterion function to select the materials from which the cable is to be fabricated and to select the best design to satisfy the minimum cost of material and minimum power losses in the cable. A personal computer is used to aid the design
