AI Technical Summary
The conductors of existing marine engineering communication cables may become misaligned and displaced due to external compression, leading to mutual compression and wear, resulting in an unstable and unsustainable structure.
The conductor is surrounded by an inner protective sleeve and an inner insulating layer, and the center frame is filled with glass fiber insulation material, external reinforcing ribs and a buffer layer, combined with a waterproof layer and an outer wear-resistant layer to form a multi-layer protective structure.
It improves the stability and durability of the cable, prevents conductor skewing and displacement and crushing wear, and enhances the safety and durability of the overall structure.
