Abstract
Systems and methods for connecting power cables to downhole equipment such as ESPs using side-exit (radial) connections. In one embodiment, a system includes an electric drive coupled by a power cable to an ESP. The electric drive is positioned at the surface of a well with the power cable coupled to it. The power cable extends into the well bore and is coupled to the downhole equipment which is positioned in the well bore. The power cable has a connector with a first set of radially oriented terminals (the terminals are perpendicular to the conductors of the power cable). These terminals engage a second set of terminals that are installed in the downhole equipment. The radial orientation of the terminals of the connector and downhole equipment allow the power cable to remain axially oriented, thereby facilitating engagement of the terminals and requiring less annular space in the well bore.
