1. A system comprising:
a tubing positionable downhole in a wellbore;
a tubing encapsulated conductor, wherein at least a portion of the tubing encapsulated conductor is positionable downhole in the wellbore to contact the tubing at a plurality of locations along a length of the tubing, the tubing encapsulated conductor comprising:
at least one interior wire positionable to transmit electricity from a power source associated with the wellbore to at least one piece of electrical equipment during a wellbore operation performed with respect to the wellbore, the at least one piece of electrical equipment positionable downhole in the wellbore;
a metal sheath positionable around the at least one interior wire; and
a conductive encapsulation layer positionable on an outer side of the metal sheath to facilitate a plurality of electrical couplings between the metal sheath and the tubing at the plurality of locations; and
wherein the tubing further comprises a plurality of cross-coupling clamps positionable at the plurality of locations, wherein each of the plurality of cross-coupling clamps electrically and mechanically couples the tubing encapsulated conductor to the tubing.
