Description

Reinforced naval vessel flexible cable

Technical field

The utility model relates to a kind of naval vessel cable.

Background technology

At present, the naval vessel on the market is generally some eradication edge core outer coated sheaths with flexible cable and makes, and the insulating barrier of insulated wire cores adopts ethylene-propylene rubber, and this type of cable can satisfy the use needs of general naval vessel with flexible cable.

But at some special occasions, after breaking down under water as submarine, first and ship tail respectively sends a rescue buoy from ship respectively, and buoy sends an SOS with signal cable by a warship, makes things convenient for so that search.Common cable weight is heavier, can cause buoy floating not.If adopt common naval vessel flexible cable, because marine stormy waves is bigger, flexible cable can rupture because of frequent distortion.So common naval vessel can not satisfy the use needs of this type of special occasions with flexible cable.The warship of other cable factories adopts cable wire as strengthening core with the cable wire signal cable, and not only external diameter is bigger, and weight is also heavier, in use can make buoy be difficult for emerging, and the cable resistance to torsion is poor.

Chinese patent literature CN201364750Y has announced a kind of naval vessel flexible cable.The flexible conductor of this cable is surrounded by second third insulating barrier outward, second third insulating barrier is extruded with the chlorsulfonated polyethylenne insulation layer outward, the outer wrapped one deck twining package tape of chlorsulfonated polyethylenne insulation layer, be filled with the elastomer rope between twining package tape and the chlorsulfonated polyethylenne insulation layer, the twining package tape outer surface is extruded with the chlorosulfonated polyethylene sheath.The insulating barrier of this flexible cable is two-layer, has guaranteed anti-the circumnutating property of cable as the elastomer rope of filler.

Chinese patent literature CN101345101A has announced a kind of underwater magnet measurement cable for ship.This cable comprises insulated wire cores group, waterstop, woven shield and the oversheath that sets gradually outside interior, the insulated wire cores group has 6 to 18 to thoroughly do away with the edge core, 6 to 18 centers of thoroughly doing away with the edge core have an aramid fiber to strengthen filling out core, the wrapped cable outside of forming in insulated wire cores of waterstop, oversheath adopts the polyurethane oversheath.Because this cable has woven shield, thus not flexible cable, and weight is heavier, and its oversheath material is not suitable for using in seawater for a long time.

Summary of the invention

A purpose of the present utility model provides a kind of flexibility, the anti-property turned round is better, intensity is higher, the reinforced naval vessel flexible cable of anti-horizontal hydraulic pressure better performances.

The technical scheme that realizes the utility model purpose is that a kind of reinforced naval vessel comprises reinforcement material, insulated wire cores, twining package tape and oversheath with flexible cable; Reinforcement material is that material is that the strengthening core or the material of aramid fiber is the reinforced layer of aramid fiber; Insulated wire cores is that the outside that the insulating barrier of ethylene-propylene rubber insulating polymeric material is coated on conductor constitutes by material; Insulated wire cores is 2 to 10;

When reinforcement material was strengthening core, insulated wire cores was the stranded stranding in center with the strengthening core; Twining package tape is wrapped on the insulated wire cores that twists together; Material is the outside that the oversheath of chlorosulfonated polyethylene macromolecular material is coated on twining package tape;

When reinforcement material is reinforced layer, the stranded stranding of insulated wire cores concentric type; Twining package tape is wrapped on the insulated wire cores that twists together; Material is that the oversheath of chlorosulfonated polyethylene macromolecular material is divided into oversheath internal layer and oversheath skin; The oversheath internal layer is coated on the twining package tape outside; Reinforced layer is coated on the outside of oversheath internal layer, and the oversheath skin is coated on the outside of reinforced layer.

Stranded the forming of tinned copper wire that above-mentioned conductor is 0.1mm to 0.68mm by 7 to 133 filament diameters, the sectional area of the stranded conductor that forms 2 is 0.5mm ²To 2.5mm ²

The thickness of above-mentioned insulating barrier is 0.5 to 2mm.

Above-mentioned twining package tape is nonwoven fabrics or polyester belt.

Above-mentioned reinforcement material is a strengthening core, and the sectional area of strengthening core is 0.5mm ²To 2.5mm ²

The thickness of above-mentioned oversheath is 1mm to 3mm.

Above-mentioned reinforcement material is a reinforced layer, and the thickness of reinforced layer is 0.5mm to 2.5mm.

The thickness of above-mentioned oversheath internal layer is 0.5mm to 2mm, and the outer field thickness of oversheath is 0.5mm to 2.5mm.

The utlity model has positive effect: (1) reinforced naval vessel of the present utility model with flexible cable at the high performance aramid fiber material of selecting certain sectional area for use during as strengthening core, because the aramid fiber material has that density is little, intensity is high, percentage elongation is little, agent of low hygroscopicity, characteristics such as fire-retardant, make the flexibility of cable, the anti-property turned round improve greatly, external diameter is littler, be 30% of cable wire signal cable, weight is lighter, is 40% of cable wire signal cable.Because alleviating of deadweight, under same pull-off force, the fail safe of cable is more reliable.(2) reinforced naval vessel of the present utility model with flexible cable when selecting for use certain thickness high performance aramid fiber material to be coated on the oversheath internal layer as reinforced layer, then the performance owing to the above-mentioned excellence of aramid fiber makes the flexibility of cable, the anti-property turned round improve greatly, and intensity is also higher.(3) insulating barrier of the present utility model adopts certain thickness ethylene-propylene rubber, makes the temperature resistant grade height of cable, and insulation resistance is good, reaches 1000M Ω km.(4) oversheath of the present utility model adopts certain thickness chlorosulfonated polyethylene material, and anti-horizontal hydraulic pressure is good, is adapted at using in the seawater.
