A self-retracting coiled cable having a variable length along a center line can include an outer insulator sleeve having a longitudinal axis. The self-retracting coiled cable can also include a spring material extending along the longitudinal axis of the outer insulator sleeve. The spring material can hold the outer insulator sleeve in a helical shape around the center line. The spring material can also allow the self-retracting coiled cable to expand upon an application of an axial force to an end of the self-retracting coiled cable, thereby increasing a length of the self-retracting coiled cable, and to retract upon a removal of the axial force from the end of the self-retracting coiled cable, thereby reducing the length of the self-retracting coiled cable. The self-retracting coiled cable can further include multiple wires extending along the longitudinal axis of the outer insulator sleeve and disposed symmetrically around the spring material.
