[0002] In recent years, with the development of submarine optoelectronic composite cables, electricity for offshore oil platforms can be first transmitted from land via submarine optical cables, then transferred to the platform via power cables through ship electrical equipment, and then converted through transformers to supply various system applications, solving the shortcomings of high energy consumption, high noise, and large space required for power generation by generator sets in the past.

[0003] With regard to the existing related technologies, the inventors believe that the following defects often exist: the cable needs to be transported over long distances from the factory to the place of use. During the transportation process and the actual use, the cable will inevitably be squeezed and scratched. The insulation layer of the cable is easily damaged by external forces and loses its original insulation performance. Discharge occurs between the cores, which easily breaks through the insulation layer and shortens the lifespan.

[0004] To this end, we propose communication cables for offshore oil platforms. Utility Model Content
