Further, the metal screen layer uses brass wire shielding or copper strip shielding with preferable fatigue behaviour.
Further, the restrictive coating uses the low density polyethylene (LDPE) with stronger waterproof performance, chlorosulfonated polyethylene, contains
One of fluorine-based polymer.
Further, the oversheath uses polyurethane or polyamide, has excellent waterproofness, wearability and tension
Property.
Further, the armor is using the strand of 2 layers or 4 layers of armouring wire and adjacent two layers armouring wire to phase
Instead, to improve the tensile strength and torsional strength of cable.
Compared with prior art, it the advantages of the utility model and has the active effect that
The utility model makes the laying up diameter conventional structure that compares have dropped 10% by dispersed placement cable core, drop
The low technology difficulty of boundling dynamic cable increases the tensile capacity of cable also with the steel strand wires added in cabling process
It bursts ability with resistance to compression, guarantees that cable is able to bear the dynamic action of top floating structure and environmental load.
