Description
Technical field
The present invention relates to electric wire field, and in particular to a kind of seabed insulative water-proof coaxial cable.
Background technology
There are abundant wind energy resources and wide flat region in China sea, and close apart from power load center, makes
Obtaining coastal waters wind generating technology turns into the focus studied and applied recently.Because seabed natural environment is severe and its unpredictable
Property, offshore wind farm are the larger cable kinds of designing technique, manufacturing technology difficulty with submarine cable.Shallow water cable does not require nothing more than anti-
The properties such as water, corrosion-resistant, resistance to mechanical drawing and external force collision, also require higher electrical insulation properties and very high safety
Reliability, particularly long length extra large cable are even more to propose great challenge to the manufacturing capacity and technical merit of current cable industry.
Shallow sea is widely used between continent and island, island and island and passed through the power transmission of rivers lakebed with cable.With
Automation and the fast development of China's marine cause, in following many decades, either Oversea wind power generation, or other coastal waters
Operating system, all huge demand will be showed to shallow water cable.Because the particular surroundings of bay application is, it is necessary to which cable has
Have different conductive sections, different mechanical strengths, anti-seawater seepage with corrosion etc. architectural characteristic, and using adapt to intertidal zone,
The different construction method such as subtidal zone, to meet the specific demand of Wind Power Generation Industry.
The content of the invention
In order to overcome the deficiencies in the prior art, there is provided a kind of seabed insulative water-proof coaxial cable, have stretching strong
The features such as spending big height, elastic and elongation percentage, caking property, water-resistance and good weatherability, can be with colod-application, and service life is longer.
To achieve the above object, the invention discloses a kind of seabed insulative water-proof coaxial cable, including positioned at cable most in
The inner conductor layer of the heart, polyurethane water-proof film is extruded outside inner conductor layer, ceramic insulating layer is externally provided with polyurethane water-proof film,
Ceramic insulating layer is externally provided with outer conductor layer, wrapped water blocking yarn outside outer conductor layer, and polyisobutene waterproofing membrane is extruded outside waterstop,
Polyisobutene waterproofing membrane is externally provided with steel wire screen layer, is externally provided with aluminium sheath in steel wire screen layer, aluminium sheath outer surface is pasted poly-
Isobutene waterproofing membrane.
Preferably, described inner conductor layer is used the frame mode of " 1+6 " by a copper conductor and six roots of sensation aluminium alloy conductor
It is twisted.
Preferably, described outer conductor layer is spaced by quantity identical copper conductor and aluminium alloy conductor and is twisted.
Preferably, described copper conductor is identical with the diameter of aluminium alloy conductor.
The beneficial effects of the present invention are：
1st, oversheath of the present invention is made of metallic aluminium, will not be burnt, and any harmful gas will not be also produced under flame condition
Body.
2nd, cable of the present invention is integrally full symmetrical configuration, and inner and outer conductor is in concentric position, and electromagnetic energy is confined to interior
Media between outer conductor, thus it is small with decaying, and shielding properties is high.
3rd, using water blocking yarn, water stop function is when meeting water using water blocking yarn fibrous body, can to expand to form volume very rapidly
(water absorption, such as can be rapid by about 0.5mm in first minute interior diameter for meeting water up to the decades of times of own vol for big jelly
It is expanded to about 5.0mm), and the water holding capacity of the jelly is quite strong, the growth of water tree can be effectively prevented, so as to prevent water
Divide and continue to penetrate into and spread, reach the purpose to block water.
4th, polyisobutene waterproofing membrane is bonded outside aluminium sheath so that cable has high tensile strength, elasticity and elongation percentage
Greatly, can be with colod-application the features such as caking property, water-resistance and good weatherability, service life is longer.
5th, cable combination of inner and outside design multilayer flashing layer so that the water resistance of cable is water-proof cable in the prior art
Hundred times, there is superpower water resistance, do not reach the water proofing property of this cable nearly all in the market.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is furture elucidated, it should be understood that these embodiments are merely to illustrate
The present invention rather than limitation the scope of the present invention, after the present invention has been read, those skilled in the art are each to the present invention's
The modification of the kind equivalent form of value falls within the application appended claims limited range.
As shown in figure 1, the present invention provides a kind of seabed insulative water-proof coaxial cable, including led in cable bosom
Body layer, the described inner conductor layer it is twisted using the frame mode of " 1+6 " by a copper conductor 1 and six roots of sensation aluminium alloy conductor 2 and
Into；Polyurethane water-proof film 3 is extruded outside inner conductor layer, ceramic insulating layer 4, ceramic insulation are externally provided with polyurethane water-proof film
Layer is externally provided with outer conductor layer, and the outer conductor layer is spaced and is twisted by quantity identical copper conductor 1 and aluminium alloy conductor 2；
Wrapped water blocking yarn 5 outside outer conductor layer, waterstop extrude polyisobutene waterproofing membrane 6 outside, are externally provided with polyisobutene waterproofing membrane
Steel wire screen layer 7, aluminium sheath 8 is externally provided with steel wire screen layer, polyisobutene waterproofing membrane 9, the electricity are pasted in aluminium sheath outer surface
The cable combination of inner and outside designs multilayer flashing layer so that the water resistance of cable is the hundred times of water-proof cable in the prior art, is had
Superpower water resistance, the water proofing property of this cable is not reached nearly all in the market.
The cable is integrally full symmetrical configuration, and inner and outer conductor is in concentric position, and electromagnetic energy is confined to internal and external conductor
Between media, therefore small with decaying, shielding properties is high.
Described above is only the preferred embodiment of the present invention, it is noted that is come for one of ordinary skill in the art
Say, under the premise without departing from the principles of the invention, some variations and modifications can also be made, these also should be regarded as belonging to the present invention
Protection domain.
