Abstract
A gap sub uses a plurality of insulating members in conjunction with at least two metallic members to effect a mechanically and electrically robust configuration. The gap sub includes an upper end portion, a lower end portion, an outer sleeve, an inner sleeve, an insulating outer washer, an insulating inner washer, and an insulating spider. The insulating outer washer is configured to transfer a first axial load between the upper end portion and the outer sleeve. The insulating inner washer is configured to transfer a second axial load between the inner sleeve and the lower end portion. The insulating spider is configured to transfer a torsional load between outer sleeve and the inner sleeve. Because the insulating washers are utilized to transfer axial loads and the insulating spider is utilized to transfer torsional loads, each insulator may be manufactured so that the strongest axis of the material can be optimally and advantageously oriented to be coincident with the forces applied to each insulator, thereby making the gap sub more mechanically robust than a conventional insulated gap collar while permitting reliable and fast transmission of sensor data to the surface.
