Abstract

The utility model discloses a double-shielded ship drag chain control cable which comprises main wire cores, control wire cores, a filling layer, an inner shielding layer, an insulating layer, an outer shielding layer, a thermal insulation layer, an ethylene propylene rubber sheath and drainage wires. There are three main wire cores. The main wire cores are uniformly extruded inside the filing layer. There are five control wire cores. The control wire cores are extruded inside the insulating layer. The control wire cores are tightly distributed and are respectively tangent to the inner shielding layer and the outer shielding layer. A waterproof layer and a metal layer are successively wrapped between the thermal insulation layer and the ethylene propylene rubber sheath. The cable provided by the utility model has good conductivity, has long service life, is drag resistant, can undergo cyclic bending for 6 million times, and has advantages of good high-and-low temperature performance, oil resistance, mechanical damage resistance, waterproofness, water-pressure resistance and high anti-interference ability.

Description

A kind of double shield boats and ships towline control cable

Technical field

The utility model relates to field of cables, relates in particular to a kind of double shield boats and ships towline control cable.

Background technology

At present, along with electric wire consumption increases rapidly, the quality requirement of cable is also constantly improved, such as the cable using in the fields such as aviation, boats and ships, electric power and tunnel, high and low temperature resistance to cable, oil resistant, resistance to mechanical damage, can waterproof, water pressure resistance, anti-interference and chemical resistance aspect require all high especially.For example present general cable just adopts merely electro-insulating rubber material aspect waterproof, and waterproof effect is bad, does not reach deep water waterproof or is in for a long time in water environment.Only meet the actual service condition of cable, the safe handling of guarantee cable.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide one and conducts electricity very well, anti-pulling, long service life, resistance to mechanical damage, energy waterproof, water pressure resistance, jamproof double shield boats and ships towline control cable.

The utility model takes following technical scheme to realize: a kind of double shield boats and ships towline control cable, it comprises master core, control core, packed layer, internal shield, insulating barrier, outer shielding layer, thermal insulation layer, ethylene-propylene rubber sheath and drainage thread, described master core is three groups, be extruded in uniformly described packed layer inside, described control core is five, the described described insulating barrier inside that is extruded in, described control core is closely arranged, respectively with described internal shield, described outer shielding layer is tangent, between described thermal insulation layer and described ethylene-propylene rubber sheath, wrap up successively watertight composition, metal level, described watertight composition is made up of the crosslinked outer non-water accepting layer of interior water accepting layer.

Three drainage threads are also wrapped up in described insulating barrier inside, and described drainage thread is that some strands of nickel plating copper wires hold annealed wire stranded forming to the right.

Described internal shield, described outer shielding layer are all to be formed by the outer aluminium foil braiding of multiply high-strength alloy copper wire.

Described master core is by 12 albronze cores and be wrapped in 12 inner insulating layer and external insulation layers outside albronze core and form, and dielectric layers is to be all made up of fluorubber material.

The utlity model has in sum following beneficial effect: this kind of cable conduction performance is good, of many uses, long service life, anti-pulling, can experience reversed bending and reach 6,000,000 times, can be subject to the hydraulic pressure of 2800 meters of water depths, be mainly used in the cable using in the fields such as aviation, boats and ships, electric power and tunnel, also have that high and low temperature resistance is good, oil resistant, resistance to mechanical damage, can waterproof, water pressure resistance, humidity, antijamming capability is strong simultaneously, can reach effect of dual shield.

Embodiment

As shown in Figure 1, a kind of double shield boats and ships towline control cable, it comprises master core 1, control core 5, packed layer 2, internal shield 3, insulating barrier 4, outer shielding layer 6, thermal insulation layer 7, ethylene-propylene rubber sheath 11 and drainage thread 10, described master core 1 is three groups, be extruded in uniformly described packed layer 2 inside, described control core 5 is five, described described insulating barrier 4 inside that are extruded in, described control core 5 is closely arranged, respectively with described internal shield 3, described outer shielding layer 6 is tangent, between described thermal insulation layer 7 and described ethylene-propylene rubber sheath 11, wrap up successively watertight composition 8, metal level 9, described watertight composition 8 is made up of the crosslinked outer non-water accepting layer of interior water accepting layer.

Three drainage threads 10 are also wrapped up in described insulating barrier 4 inside, and described drainage thread 10 holds annealed wire stranded forming to the right for some strands of nickel plating copper wires.

Described internal shield 3, described outer shielding layer 6 are all to be formed by the outer aluminium foil braiding of multiply high-strength alloy copper wire.

Described master core 1 is by 12 albronze cores and be wrapped in 12 inner insulating layer and external insulation layers outside albronze core and form, and dielectric layers is to be all made up of fluorubber material.

This cable allows experience reversed bending to reach 6,000,000 times, can be subject to the hydraulic pressure of 2800 meters of water depths; The permission bending radius of this cable is the outside diameter of cable 10 times.

The above is embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
