Torque-balanced electrical cable

A wellbore cable, comprising:

• a cable core comprising a soft polymer central element disposed between three conductors, wherein the soft polymer central element is deformed completely filling the interstitial space between the conductors;
• wherein a diameter of a circle passing through the centers of each of the conductors is approximately the same size as the individual diameter of each of the three conductors;
• at least a first armor wire layer comprising a plurality of strength members and surrounding the cable core;
• at least one layer of a polymeric material surrounding the cable core and the first armor wire layer and defining a predetermined radial thickness;
• and
• at least a second armor wire layer comprising a plurality of strength members surrounding the first armor wire layer and partially disposed within the polymeric material, the polymeric material defining a predetermined radial spacing between the first armor wire layer and the second armor wire layer, the second armor wire layer covering a predetermined percentage of the circumference of the first armor wire layer, wherein the predetermined percentage is from 50 percent to 90 percent, and wherein the number of strength members in the first armor wire layer is equal to the number of strength members in the second armor wire layer.
