Abstract
A string of coiled tubing having a power cable therein supports and supplies power to an electrical submersible well pump assembly in a well. The coiled tubing has an upper section and a lower section joining each other, the upper section having a smaller inner diameter than the lower section. The power cable has an upper portion installed in the upper section of the coiled tubing and a lower portion installed in the lower section of the coiled tubing. The power cable has three insulated electrical conductors embedded within an elastomeric jacket. A metal armor strip has turns wrapped helically around the jacket. The armor strip is compressed between the jacket and the coiled tubing both in the upper section and in the lower section of the coiled tubing.
