Abstract

The utility model discloses a cable for ships, which comprises a cable core, wherein the cable core is formed by stranding a plurality of insulated wire cores; a filling layer is arranged in gaps of the cable core, the cable core is wrapped with a low-smoke halogen-free isolating belt, and the low-smoke halogen-free isolating belt is extruded with a low-smoke halogen-free flame retardant rubber sheath; and each insulated wire core is composed of a conductor and a high resistance thin insulating layer extruding outside the conductor. The cable for ships has the properties of flexibility, tear resistance, salt spray resistance, acid and alkali resistance, tension resistance and the like; the wire diameters of copper wires adopted by the conductors are smaller, and the cable manufactured by using the copper wires has better flexibility. The insulation and sheath of the cable for ships adopt two types of different materials, the advantages of rubber and plastics are organically combined, so that the problem that the flexibility and light weight cannot be simultaneously ensured is solved, and the cable is applicable to the environment in the sea.

Description

A kind of cable for ship

Technical field

The utility model belongs to power cable field, is specifically related to a kind of cable for ship.

Background technology

Existing cable for ship mainly can be divided into two kinds according to the material of its use, and a kind of is the cable (calling rubber cable in the following text) that insulation and sheath are rubber, and another kind of insulation and sheath are the cable (call in the following text and mould cable) of plastics.Both all have feature separately, and rubber cable has the advantages that softness is good, are therefore applicable to frequently mobile use on naval vessel, and mould cable cable as fixing use on naval vessel, seldom move.

Problem and shortcoming that prior art exists:

Although existing ship cable properties can meet the requirement of naval vessel standard, but in long-term use, still there are various uncertain factors and affected use, mould at present cable insulation used and sheath material and mostly be polythene material, there is relative density little, good mechanical strength, the features such as point insulating, but harder at cable when installing and laying, bending radius is larger, is unfavorable for installing; Although and rubber cable has the feature of good bending property, its weight is also heavier, some cable is for a long time on ship deck, so the sheath performance of cable can not meet instructions for use.

Utility model content

The purpose of this utility model is to provide a kind of cable for ship with softness, tear-proof, salt spray resistance, acid and alkali-resistance, resistance to tension.

A kind of cable for ship described in the utility model, comprises cable core, and its cable core is by many stranded the forming of insulated wire cores; Cable core gap is provided with packed layer, and the outer wrapped low smoke and zero halogen of cable core isolation strip, extrudes low-smoke and halogen-free fire-retardant rubber sheath again outside low smoke and zero halogen isolation strip; Described insulated wire cores consists of conductor and the high resistance thin dielectric layer that is extruded in outside conductor.

Further improve, described conductor is tinned copper conductor.

The beneficial effects of the utility model are:

In order to make cable have good weatherability, salt fog resistance, take into account the weight that reduces cable simultaneously, and there is the good feature of softness, first from the insulation aspect of cable, what adopt is high resistance thin insulating, and this insulation is to belong to low smoke and zero halogen cross-linking radiation material, and its intensity can reach 20N/mm ², its insulation resistance reaches 351700 M Ω ㎞, and can reduce insulation thickness under the prerequisite that does not affect instructions for use, and the overall weight that realizes cable reduces; Secondly, the rubber sheath on naval vessel adopts low-smoke and halogen-free fire-retardant rubber, the performance that meets low-smoke non-halogen flame-retardant guarantees that the tear strength of finished cable can reach 8.0N/mm left and right (standard-required 6.1N/mm) simultaneously, this index is much higher than standard both domestic and external, this sheath is applicable to the environment using on ocean, has the performances such as softness, tear-proof, salt spray resistance, acid and alkali-resistance, tension; Finally, the copper wire string diameter adopting due to conductor is less, and the cable softness made from this type of copper wire is better.Insulation of the present utility model adopts with sheath the material that two classes are different, and the advantage of rubber and plastics is organically combined, and has solved flexibility and the lightweight problem that can not take into account.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Embodiment

As shown in Figure 1, a kind of cable for ship described in the utility model, comprises cable core, and its cable core is by many stranded the forming of insulated wire cores; Cable core gap is provided with packed layer 3, the outer wrapped low smoke and zero halogen of cable core isolation strip 4, the outer low-smoke and halogen-free fire-retardant rubber sheath 5 that extrudes again in low smoke and zero halogen isolation strip 4; Described insulated wire cores consists of conductor 1 and the high resistance thin dielectric layer 2 that is extruded in outside conductor 1.Described conductor 1 is tinned copper conductor.

The utility model provides a kind of cable for ship; the above is only preferred implementation method of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
