Technical field

This utility model relates to field of cable technology, particularly relates to the coaxial degaussing cable of a kind of two-conductor structure.

Background technology

The effect of degaussing cable is for ship deperming, have fixing lay and move lay two kinds, due to the cable of the type Life-time service is in having briny environment, and therefore, such cable, because having good weather-proof, salt spray resistance, is used at present Cable can reach this requirement the most substantially, but is as the life-time service of cable, cable be extremely easily subject to marine organisms or Other microorganism parasitisms corrode, and are susceptible to puncture, thus reduce the service life of cable.

Prior art uses bracing frame to be supported cable, protects coaxial demagnetization electricity by the form increasing bracing frame Cable, has certain effect, but adds laid down cost and time, and the load-carrying properties of cable own are poor in addition, difficult in work progress Exempting from can be because operating the problem causing the core of cable to damage accidentally；Prior art major part is all to use metal compression tube to increase Adding compressive property, owing to using metal, and other layers are plastic layer, and amalgamation is poor from each other, affects the performance of cable； Existing cable jacket is all to use the mode that extrudes to be extruded in outermost layer, this mode time length, easily relaxes or de- From；It addition, major part cable is all too high by temperature, causes spontaneous combustion, cause the biggest loss.

Utility model content

This utility model is in order to solve problem of the prior art, it is provided that a kind of from carrying and compressive property, moistureproof and Good airproof performance, flexibility is good, it is little to decay, shield effectiveness good, can simultaneously work as monitoring the same of cable temperature effect two-conductor structure Axle degaussing cable.

The coaxial degaussing cable of a kind of two-conductor structure described in the utility model, includes inner wire, rubber from inside to outside Insulating barrier, outer conductor, rubber sealing coat and oversheath；Described inner wire is by carrying core at its center and with carrying Core is that some aluminium alloy conductors that the center of circle is centered around outside strengthening core are stranded to be formed；Outer conductor is symmetrical with cable center by four Strengthening core and some copper conductors combine；It is provided with plastic flexible pipe between rubber sealing coat and oversheath；Described outer protect Putting and be additionally provided with temperature sense alarm, the height of temperature sense alarm is not more than 0.3mm, and width is not more than 0.8mm；Described Plastic flexible pipe be provided with four tongues, oversheath is provided with four grooves corresponding with tongue.

Improving further, the thickness of described rubber insulation is 2 times of rubber isolation strip thickness, wherein, rubber-covered The thickness of layer is 1.325-1.625mm.

Improving further, described carrying core is steel wire rope.

Improving further, described strengthening core is by center zinc-coated wire and the plastic protective layer that is extruded in outside zinc-coated wire Constitute.

Compared with prior art, this utility model has the beneficial effects that:

1, this utility model has the strongest from load-carrying properties, the conductor center layer You Yigen center carrying core of cable, The stress point of inner wire concentrates on center carrying core, and cable, in folding and unfolding winding process, protects inner wire, and the most easy to break Disconnected；

2, this utility model has the strongest reinforcing property, is provided with four strengthening cores in the outer conductor of cable, forms one Rack-like structures, the stress point of outer conductor concentrates on strengthening core, and cable, in folding and unfolding winding process, protects outer conductor, and And be not easily broken, and be externally provided with protective layer, not only acting as the effect of protection zinc-coated wire, prevent zinc-coated wire with Interfering with each other and rubbing between copper wire, affects the performance of cable；

3, this utility model use plastic flexible pipe alternative metals compression tube, have more preferable mechanical strength height, compressive property, Also make cable the most soft while protection against the tide and sealing, bending property, and plastics can with the amalgamation of other layers more Good；

4, oversheath uses polyurethane material to constitute, and has intensity high, and the advantage that anti tear, percentage elongation are good has simultaneously Lightweight advantage, very convenient manually lays.

5, the oversheath that polyurethane material is constituted, its surface is the most smooth, can ensure the use under salt mist environment for a long time In the life-span, self-cleaning ability is strong simultaneously, and marine growth is difficult to be attached to cable surface, and compared with prior art, its service life adds 2 More than Bei.

6, the thickness of rubber insulation is 2 times of rubber isolation strip thickness, this ensure that the overall rounding property of cable, makes Obtain each performance of cable better.

7, this utility model oversheath is additionally provided with temperature sense alarm, can detect cable variations in temperature operationally, If exceeding the temperature that this cable is born, alarm will be reported to the police, and staff just can cut off the electricity supply, and prevents cable from being burnt Bad, add safety, it is to avoid cable fire and the loss that causes, also save cost.

8, in order to make cable jacket be difficult to lax and depart from, oversheath and plastic flexible pipe are provided with tongue and recessed accordingly Groove, oversheath is told in groove by what groove snapped in flexible pipe so that the structure of cable is consolidated for a long time, it is ensured that cable performance Stability.
