A well system incorporates electrically conductive mesh providing robust, reliable electrical communication pathways along portions of tubular equipment. An example system comprises a tubular string disposed in a wellbore, such as a multilateral wellbore. The tubular string defines an internal fluid flow path for conveying fluids to or from a surface of a wellsite. The tubular string also includes a plurality of well components with tubular component bodies arranged along the tubular string. An electrical network along the tubular string interconnects the well components. The electrical network comprising a transmission path defined at least in part by a mesh sleeve disposed along the tubular string around the internal fluid flow path.
