I can the built the app based on calculation. The input will be like AC or DC, voltage level, peak power, cable type etc. which fetch the result recommended cable dimension, yearly energy loss and max voltage drop. Hope you will provide the "formulas" to built the app. I will first make screen design after approved of design I will start to develop. Hope the final output will satisfy your need.
