Zusammenfassung:PROBLEM TO BE SOLVED: To stabilize a surface buoy with a transmission cable, which does not exert unnecessary higher load, and provide a transmission cable structure capable of counteracting driftage by constituting a transmission cable from the surface buoy to an intermediate buoyant body, combining a plurality of cables having different specific gravities and strengths. SOLUTION: An A cable 12a using a steel wire as a tensile strength body, having a large specific gravity is connected directly under a surface buoy 11 to obtain submerged weight corresponding to the buoyancy of the surface buoy 11 and to stabilize the floating state of the surface buoy 11. A B cable 12b using high strength synthetic fibers as a tensile strength body, having a small specific gravity is connected under the A cable 12a for reducing a load to buoyancy of the surface buoy 11. As a transmission cable 12 between the surface buoy 11 and a sensor part 3 moored under the sea, the A cable 12a having a large specific gravity and high strength and the B cable having a small specific gravity are combined to stabilized the floating state of the surface buoy 11, and damages from drifitage or fish bits or the like is prevented.
