| 摘要 |
<p>The invention relates to a cable (10) having an elongate core (20) made of a first dielectric material and having a core outer surface (25); and a plurality of elongate conducting elements (30) arranged about the elongate core (20). The elongate conducting elements (30) have an inner conductor (40) surrounded by an insulating layer (50) which is made of a second dielectric material. The outer surface of the inner conductor (40) is divided into a first outer surface area (60) and a second outer surface are a (70) and the first outer surface area (60) is attached, for example by sintering, to the core outer surface (25). The first and second dielectric materials are preferably expanded PTFE. The cable (10) finds application in a streamer (100) for use in seismographic surveys of the ocean bottom sub surface.</p> |
