Description

A kind of marine with moistureproof ageing-resistant LP blades cable

Technical field

This utility model relates to field of cables, particularly relates to a kind of marine moistureproof ageing-resistant LP blades cable.

Background technology

At present, along with science and technology development, industry etc. field also at rapid advances, bring therewith is The increase of cable consumption, cable is typically several or at least two stranded classes often organized by several groups of wires Like the cable of rope, often mutually insulated between group wire, and be often twisted into around a center, whole outside Being surrounded by the cover layer of high-insulation, the kind of cable has a lot, can apply in a lot of fields different Field in use environment be different, therefore cable is also had different requirements, existing electricity Cable is easy to situation short circuit occur in working in the environment of some humidities, moisture can be easily through electricity Cable sheath enters inside cable, brings a lot of inconvenience to the use of people.

Utility model content

In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of marine with anti- The ageing-resistant LP blades cable of tide.

This utility model takes techniques below scheme to realize: the protection against the tide of a kind of sea is ageing-resistant to be prevented invading Erosion cable, it includes that cable body, described cable body include conductor, water accepting layer, stain-proofing layer and protect outward Set, described cable body is internally provided with multiple conductor；Described conductor outer wrapping layer of metal protective layer； Described coat of metal and conductor collectively form cable core；Described cable body is internally provided with multiple cable core； One layer of stain-proofing layer is extruded outside described cable core；Multiple guide core it is surrounded with inside described stain-proofing layer；Described Layer of polyethylene anticorrosive coat is extruded outside stain-proofing layer；One layer of enhancement Layer is extruded outside described polyethylene anticorrosive coating；Institute State and outside enhancement Layer, closely extrude one layer of cellosilk braid；Protect outside extruding one layer outside described cellosilk braid Set.

Above-mentioned is a kind of marine with moistureproof ageing-resistant LP blades cable, gap between described stain-proofing layer and cable core Part is provided with water accepting layer.

Above-mentioned is a kind of marine with moistureproof ageing-resistant LP blades cable, is surrounded with inside described enhancement Layer Many elastic adhesive tapes.

Above-mentioned a kind of marine with moistureproof ageing-resistant LP blades cable, described conductor is spiral type wrinkles aluminium tube Structure.

Above-mentioned a kind of marine with moistureproof ageing-resistant LP blades cable, described oversheath is polyurethane polymer Material is made.

In sum this utility model have the advantages that this utility model have reasonable in design, Moisture effect is good and the advantage such as length in service life, and described oversheath uses polyurethane polymer material to make, So that cable has good insulating properties and Inverter fed motor ability, it also is able to keep in the case of making moist Stable, also there is good insulation characterisitic.

Accompanying drawing explanation

Fig. 1 is this utility model cross-sectional structure schematic diagram；

Wherein: 1, cable body；2, conductor；3, coat of metal；4, water accepting layer；5, stain-proofing layer； 6, guide core；7, polyethylene anticorrosive coating；8, enhancement Layer；9, elastic adhesive tape；10, cellosilk braiding Layer；11, oversheath.

Detailed description of the invention

As it is shown in figure 1, a kind of marine with moistureproof ageing-resistant LP blades cable, it includes cable body 1, institute State cable body 1 and include conductor 2, water accepting layer 4, stain-proofing layer 5 and oversheath 11, described cable body 1 It is internally provided with multiple conductor 2；Described conductor 2 outer wrapping layer of metal protective layer 3；Described metal coating Layer 3 and conductor 2 collectively form cable core；Described cable body 1 is internally provided with multiple cable core；Described cable One layer of stain-proofing layer 5 is extruded outside core；Described stain-proofing layer 5 is internal is surrounded with multiple guide core 6；Described anti- Layer of polyethylene anticorrosive coat 7 is extruded outside pollution layer 5；One layer of enhancement Layer 8 is extruded outside described polyethylene anticorrosive coating 7； Described enhancement Layer 8 is outer closely extrudes one layer of cellosilk braid 10；Extrude outside described cellosilk braid 10 One layer of oversheath 11.

Described stain-proofing layer 5 can effectively prevent marine organisms and the microorganism erosion to submarine cable, protects Demonstrate,prove the service life of cable body 1；Described polyethylene anticorrosive coating 7 can effectively eliminate cable body 1 The induced potential produced；Described enhancement Layer 8 can enable the deadweight that submarine cable bears sufficient length cable Pulling force and external tensile force, simultaneously from laying and damage to cable during operation on the sea, and will not be by sea Aqueous corrosion；Even if described cellosilk braid 10 in use cable reverses for a long time does not also have fracture Situation, it is possible to ensure the normal use of cable body 1, and enhance the load bearing stength of cable body 1； Described oversheath 11 uses polyurethane polymer material to make, so that cable has good insulating properties And Inverter fed motor ability, it also is able to keep stable in the case of making moist, also there is good insulation characterisitic.

The above is embodiment of the present utility model, therefore all according to the structure described in this utility model application range Make, equivalence change that feature and principle are done or modify, be all included in this utility model patent claim In.
