Abstract

The utility model relates to a marine watertight cable. The technical problem to be solved is to provide a cable which has the characteristics of high strength, wear resistance, seawater corrosion resistance and no longitudinal water leakage. The technical scheme is that the marine watertight cable comprises an inner conductor, and an insulation layer, an outer conductor layer for shielding and an outer sheath coaxially coating the inner conductor from inside to outside, and the marine watertight cable is characterized in that a plurality of bare copper wires are stranded into the inner conductor; organosilicon cable-sealing gum is filled among the bare copper wires; an aramid fiber layer for stopping water is coaxially arranged between the shielding layer and the outer sheath; waterproof factice is filled between the shielding layer and the insulation layer; the insulation layer is a high-pressure polyethylene layer; and the outer sheath is a polyurethane sheath.

Description

A kind of naval vessel watertight cable

Technical field

The utility model relates to a kind of cable, specifically the watertight cable of naval vessel special use.

Background technology

Mainly as the feeder line of the transmission of ship communication system signal or sender, and the naval vessel wears the storehouse and connects with the watertight coaxial cable on the naval vessel, and reliability standard is higher; And require cable end face (axially) energy water pressure resistance, at specified testing pressure with in the time, do not allowed water to ooze out.Common cable fails to satisfy above-mentioned requirements, thereby is necessary to be improved.

The utility model content

Technical problem to be solved in the utility model is the deficiency that overcomes the above-mentioned background technology, and the coaxial cable that provides a kind of naval vessel to use, this cable have that intensity is high, wear-resisting, seawater corrosion resistance and vertical watertight characteristics.

The technical scheme that the utility model provides is: a kind of naval vessel watertight cable comprises inner wire and from inside to outside coaxial coating insulating barrier in the conductor, outer conductor layer and the oversheath of shielding usefulness; It is characterized in that described inner wire is many stranded the forming of bare copper wire, is filling the organosilicon cable sealing glue between each bare copper wire; The block water aramid layers of usefulness of coaxial coating one also between described screen and the oversheath.

Be filled with the ointment that waterproof is used between described screen and the insulating barrier.

Described insulating barrier is the polyethylene from high pressure process layer.

Described oversheath is polyurethane jacket.

The beneficial effects of the utility model are:

1) inner wire adopts many bare copper wires (being shown as seven bare copper wires among the figure) lay configuration, can make cable have preferably flexibility; Simultaneously in stranded process, the silica filled organopolysiloxane cable sealing glue between bare copper wire of continuous uniform, thus make stranded inner wire shape direction waterproof structure.

2) add on the outer conductor layer to twine and form an aramid layers behind the aramid fiber waterstop, oversheath adopts pressure type to extrude formation, make close structure between oversheath and insulator, the outer conductor layer, and aramid fiber waterstop and polyurethane jacket are combined together, guaranteed the interface direction waterproof superior performance between oversheath and insulator, the outer conductor layer.

3) insulating barrier adopts the polyethylene from high pressure process pressure type to extrude formation; Intensity is high, and compactness is good, and block-water effect is good.

4) product have that little, the anti-tampering ability of signal attenuation is strong and intensity is high, the characteristics of wear-resisting, seawater corrosion resistance.

Embodiment

Because the environment on naval vessel is special, for guaranteeing that communication is good on the naval vessel, each member and the faying face between the member thereof of the watertight cable that adopts all require direction waterproof functional.

For this reason, the naval vessel that the utility model provides watertight coaxial cable, inner wire 1 adopts many stranded the forming of bare copper wire (preferred seven bare copper wire); In the stranded process of bare copper wire, continuous uniform ground silica filled organopolysiloxane cable sealing glue between bare copper wire again.Outer from inside to outside coaxial outer conductor layer 3, water resistance aramid fiber layer 4 and the oversheath 5 that is coated with insulating barrier 2, shielding usefulness successively of inner wire.Wherein, insulating barrier adopts high-pressure polyethylene material and extrudes formation by pressure type.

Outer conductor layer forms a wire sheathing by many one metal wire braidings are rear, has good shield effectiveness; Be filled with the ointment (being the POA ointment) that waterproof is used between screen and the insulating barrier, have good block-water effect; The water resistance aramid fiber layer is that external peripheral surface at insulating barrier forms after with aramid fiber waterstop uniform winding; With pliability is good, grease resistance is high, extrude as the oversheath material after wear-resisting, the corrosion resistant polyurethane heat treated, improved the resistance to wear, corrosion-resistant of cable, make cable in the situation that long-term motion and corrosion, the stability of inhibit signal transmission.

The utlity model has the high characteristics of watertightness; Be particularly suitable for using on the naval vessel.
