Abstract

The utility model relates to a floating cable used in water, comprising an insulation layer outside an inner conductor, wherein the insulation layer is composed of an inner insulation layer, an outer insulation layer, a weaving layer and a protection sheath. The inner insulation layer is TPE elastomeric material. The outer insulation layer is TPE foaming material. The weaving layer is aramid fiber weaving layer. The protection sheath is polyurethane protection sheath. The beneficial effects are that: 1, the inner insulation and the foaming material use the TPE elastomeric material to make the cable more soft; 2, the outer insulation layer uses the TPE foaming material with smaller density and lighter weight to effectively control the small density of the whole cable; 3, the mechanical performance is good: after foaming the TPE material also has very high intensity; 4, the aramid fiber weaving structure greatly strengthens the stretching resistance of the cable and the intensity can be 10MPa; 5, the polyurethane protection sheath has features of oil resistance, low temperature resistance and fire retardation to make the cable used at the extreme condition.

Description

A kind of buoyant cable

Technical field

The utility model relates to a kind of cable, particularly is used for a kind of buoyant cable of water.

Background technology

Development along with marine industries and underwater robot industry, the cable of transmission usefulness is proposed the requirement of water float, therefore use this kind cable can reduce robot stube cable when operation its power that pulls is just required that cable is littler to density, weight is lighter, resistance to tension is stronger, more direction such as softness develops.General buoyant cable has only monolayer insulating layer and adopts polyethylene foamed as insulating material, and the foam degrees of this series products is smaller, and density is bigger, and insulating barrier is harder, and crooking ability is poor, resistance to tension is not organized, and can not satisfy the job requirements of underwater robot.

Summary of the invention

In view of the deficiency that prior art exists, the utility model provides a kind of a kind of buoyant cable that is provided with the braiding of multi-layer insulating structure peripheral hardware aramid fiber and adopts novel expanded material outside conductor.

The utility model for achieving the above object, the technical scheme that is adopted is: a kind of buoyant cable, the insulating barrier that the conductor that included is provided with outward is characterized in that: described insulating barrier is inner insulating layer, external insulation layer, braid, sheath four-layer structure; Described inner insulating layer is the TPE elastomeric material; Described external insulation layer is the TPE expanded material; Described braid is an aramid fiber silk braid.Described sheath is a polyurethane jacket.

The beneficial effects of the utility model are: 1, interior insulation and expanded material have adopted the TPE elastomeric material, make cable soft more.2, external insulation layer has adopted the TPE expanded material, and the density of expanded material is littler, and in light weight, and the density of effectively having controlled whole cable is little.3, good mechanical property: foaming back TPE material still has very high intensity.4, aramid fiber silk braiding structure can be strengthened the stretching resistance of cable greatly, and intensity can reach 10Mpa.5, the polyurethane jacket oil resistant is low temperature resistant, and is fire-retardant, and cable can under extreme conditions be used.

Description of drawings

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

Embodiment

As shown in Figure 1, a kind of buoyant cable, the conductor 1 outer insulating barrier that is provided with that included, it is characterized in that: described insulating barrier is inner insulating layer 2, external insulation layer 3, braid 4, sheath 5 four-layer structures.

The utility model can obtain by following technical process manufacturing: use electric wire cable strand machine or the stranded multiply tinned copper wire of bunching machine as inner wire 1, outside inner wire 1, extrude one deck TPE elastomeric material as inner insulating layer 2, outside inner insulating layer 2, extrude one deck TPE expanded material as external insulation layer 3, the braid 4 of braiding one deck aramid fiber wire material is extruded one deck polyurethane jacket 5 outside braid 4 outside external insulation layer 3.
