The image to the right shows the various ‘’layers’’ in an ESP cable. There are three conductors which are at the core of the cable. These conductors are made of copper (because copper is a good conductor of electricity as it has free moveable electrons) and coated with a lead-tin alloy material. Each conductor is insulated to prevent electric shock, over which a barrier is placed to provide mechanical protection
