An electrical cable includes insulated primary conductors and at least one insulated secondary conductor, which extend along the cable. The primary conductors define interstitial spaces between adjacent primary conductors, and the primary conductors have approximately the same diameter. The primary conductors include power conductors and a telemetric conductor. The secondary conductor(s) each have a diameter that is smaller than each of the diameters of the primary conductors, and each secondary conductor is at least partially nested in one of the interstitial spaces. The electrical cable may include at least one fiber optic line.
