Electric power is transmitted to the motor by a specially designed cable which extends from the top of the motor to the wellhead, supported along the tube with cable bands or clamps. Although round cables are more common, it may prove necessary to use flat cables when the space between the tubing collars and casing ID is restricted.
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
