Abstract
The present invention relates to a downhole transfer system for transferring data through a well tubular metal structure arranged in a borehole of a well, comprising a well tubular metal structure having an axial direction and being arranged in the borehole providing an annulus between the borehole and the well tubular metal structure, a transceiver assembly comprising a tubular metal part mounted as part of the well tubular metal structure, the tubular metal part having an inner face, an outer face and a wall, an assembly conductive winding, such as a copper ring, connected with the inner face, a power consuming device, such as a sensor, arranged in the annulus and connected with the outer face and the power consuming device is connected to the assembly conductive winding by means of an electrical conductor, a downhole tool comprises a tool body, a tool body outer face and a tool conductive winding, wherein the assembly conductive winding has an axial extension along the axial direction and a radial extension perpendicular to the axial extension, the axial extension being at least 50% larger than the radial extension.
