Abstract:
A wellhead for sealing with a continuous electrical power cable for powering a downhole electrical submersible pump including an electrical motor within a well bore, the electrical power cable passing without interruption through the wellhead for electrically connecting the motor with an electrical power source external of the wellhead, the wellhead comprising:a wellhead body for supporting a tubing hanger at least partially therein; the tubing hanger including a tubing port for conducting a fluid from the submersible pump through the tubing port, and a power cable port having a cable axis for passing electrical power from the electrical power source through the power cable port to the electric motor; a cable seal within an annulus between the outer diameter of the power cable and an inner diameter of the power cable port for pneumatically sealing between the power cable and the wellhead body; a lower packing seat for supporting the cable seal; and a packing gland selectively moveable with respect to the seat for compressing the cable seal to form a pneumatic seal.
