A method for manufacturing a motor lead cable includes the steps of forming one or more motor leads and placing external armor around the one or motor leads. The step of forming each of the one or more motor leads includes providing an insulated conductor, providing an open capillary tube that has opposing sides that have not been joined together, placing the insulated conductor inside the unclosed capillary tube, approximating the sides of the unclosed capillary tube around the insulated conductor, and welding the sides of the capillary tube together to form a closed capillary tube around the insulated conductor.

An electric submersible pumping system includes a motor, a pump driven by the motor, and a cable that provides electrical power to the motor. The cable includes a conductor and an insulator surrounding the conductor. The insulator includes a first layer surrounding the conductor and a second layer surrounding the first layer. The insulator may include an HS scavenger and an HS reactant in the first or second layers surrounding the conductor. The cable optionally includes a sub-insulator layer that includes a metal or nitride coating applied directly to the conductor.
