A cable anti-torsion device
The present invention discloses a cable anti-torsion device for connecting underwater cables to surface floats. By adding a protective layer to the cable's outer surface, the cable's torsional strength is increased, allowing the surface float's rotation to be released via a slip ring, preventing damage to the cable due to excessive twisting. Specifically, a protective layer of a set length is applied to the cable's outer layer, starting at the point where the cable connects to the connector. This ensures that the tensile strength of the cable segment covered by the protective layer is greater than the initial torque required to initiate the slip ring's rotation. This device can mitigate the effects of the surface float's long-term rotation on the cable, protecting the cable and ensuring proper system operation.
