Description
Technical field
It the utility model is related to electric wire field, and in particular to a kind of mineral insulation aluminium sheath flexible water 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.
Utility model content
In order to overcome the deficiencies in the prior art, there is provided one kind has tensile strength high, and elasticity and elongation percentage are big, glues
Knot property, water-resistance and the good mineral insulation aluminium sheath flexible water cable of against weather.
To achieve the above object, the utility model provides a kind of mineral insulation aluminium sheath flexible water cable, including cable core,
Described cable core is twisted by more insulated wire cores, in the gap factice for filling of cable core；Wrapped polyurethane is prevented outside cable core
Water film, the second mineral insulation is extruded outside waterproofing membrane, inner sheath is externally provided with, outside inner sheath in the second mineral insulation
Provided with outer ethylene propylene diene rubber waterproof layer, the wrapped polyisobutene waterproofing membrane outside outer ethylene propylene diene rubber waterproof layer；Poly- different
Aluminium-plastic tape waterproof layer is extruded outside butylene waterproofing membrane, aluminium alloy armored band is woven in aluminium-plastic tape waterproof layer, finally exists
Aluminium sheath is extruded outside aluminium alloy armored band, is scribbled outside aluminium sheath after water-repellent paint further around bag polyurethane water-proof film.
Preferably, described insulated wire cores are by aluminium alloy conductor, the first mineral insulation being extruded in outside aluminum alloy copper conductor
Layer, overlapping wrapped interior ethylene propylene diene rubber waterproof layer outside the first mineral insulation and it is extruded in interior ethylene propylene diene rubber and prevents
Ceramic silicon rubber band outside water layer is formed.
Preferably, the first described mineral insulation is formed for magnesium oxide insulated material.
Preferably, the second described mineral insulation is formed for magnesium oxide insulated material.
Compared with prior art, the beneficial effects of the utility model are：
1st, the utility model is simple in construction, by metallic sheath using corrugated aluminum pipe etc., not only simplifies technique and improves effect
Rate, and product cost is declined to a great extent.
2nd, the utility model employs multilayer material water-proof material so that cable has very strong water stop function, will not be because of water
Sub-dip enters to cause the oxidation of conductor, corrosion, so as to influence the electrical property of cable, or even abnormal broken line accident occurs.
3rd, filling uses ointment so that cable has good caking property, plasticity, water-resistance, anti-corrosive properties and durability.
4th, the inside and outside wrapped polyurethane water-proof film of cable so that cable has tensile strength high, and elasticity and elongation percentage are big,
The features such as caking property, water-resistance and against weather are good, can be with colod-application, and 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 structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after the utility model has been read, art technology
Modification of the personnel to the various equivalent form of values of the present utility model falls within the application appended claims limited range.
As shown in figure 1, the utility model provides a kind of mineral insulation aluminium sheath flexible water cable, including cable core, it is described
Cable core formed by a pair of insulated wire cores pair twists, described insulated wire cores by aluminium alloy conductor 1, be extruded in outside aluminum alloy copper conductor
The first mineral insulation 2, overlapping wrapped interior ethylene propylene diene rubber waterproof layer 3 outside the first mineral insulation and be extruded in
Ceramic silicon rubber band 4 outside interior ethylene propylene diene rubber waterproof layer is formed.Then, in the gap factice for filling 5 of cable core；In cable
Wrapped polyurethane water-proof film 6 outside core, extrudes the second mineral insulation 7 outside waterproofing membrane, in the second mineral insulation peripheral hardware
There is inner sheath 8, be externally provided with outer ethylene propylene diene rubber waterproof layer 9 in inner sheath, it is wrapped poly- outside outer ethylene propylene diene rubber waterproof layer
