Abstract
A submersible cable for a fish-repelling installation comprises a central conductive-wire core covered with a conductive smoothing layer and then with an insulating layer. A first conductive layer is applied over this first insulating layer, then a second insulating layer and a second conductive layer that constitutes a field limiter. Armor in the form of synthetic-resin strands is then wound over the cable and a waterproof layer is applied to the outside of the cable. After the application of each insulating layer the cable is tested for leakage in order to repair any discovered leaks before the next conductive layer is applied to the cable.
Claims8
A submersible cable for a fish-repelling installation, said cable comprising a central metallic conductive core;
- a smoothing conductive layer surrounding said core;
- a discharge-proof insulating layer surrounding said smoothing conductive layer;
- a conductive field-limiting layer surrounding said insulating layer;
- and armoring insulation including a plurality of synthetic resin filaments wound around the outside of said field limiting layer and a watertight filling in the interstices between said filaments;
- and a discharge-proof layer of wear-resistant dielectric material of different material than the watertight filling surrounding said armoring insulation.
