Seismic conductive rope lead-in cable |
摘要 |
A conductive rope-like lead-in cable connects a seismic streamer to a towing vessel. The lead-in cable comprises a first electrical conductor at the center core of the cable for carrying a first polarity of power to the streamer for providing tensile strength to the load-in cable. A first layer of insulation surrounds the first electrical conductor. A second electrical conductor for a second polarity of power to the streamer surrounds the first layer of insulation. A second layer of insulation surrounds the second electrical conductor. A layer of seismic data conductors surrounds the second layer of insulation. A third layer of insulation surrounds the layer of seismic data conductors. A metallic protective layer surrounds the third layer of insulation. Steel is effectively and efficiently used both to provide tensile strength and for electrical power conduction. |
