Description
Technical field
The present invention relates to electric wire field, and in particular to a kind of double sheath flexible water electric power electricity of ceramic insulation double shield
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 one kind has tensile strength high, and elasticity and elongation percentage are big, glues
Knot property, water-resistance and the good double sheath flexible water power cables of ceramic insulation double shield of against weather.
To achieve the above object, the present invention provides a kind of ceramic insulation double shield double sheath flexible water power cables, bag
Cable core is included, described cable core is twisted by more ceramic insulation cores and with the same number of steel core of ceramic insulation core,
Cable core gap is provided with water blocking yarn, the wrapped waterstop outside cable core, and the polyethylene bonding of aluminium one is extruded outside waterstop and is blocked water interior shield
Set, blocked water in the polyethylene bonding of aluminium one and extrude the second ceramic insulating layer outside inner sheath, polyisobutene is bonded outside ceramic insulating layer
Waterproofing membrane, steel band screen layer is first woven outside polyisobutene waterproofing membrane, then weaves aluminium strip screen layer, steel band screen layer with
Aluminium strip screen layer is externally provided with separation layer, and the oversheath that blocks water is extruded outside aluminium strip screen layer；The intermediate layer of the described oversheath that blocks water
For polyethylene outer sheath, polyurethane water-proof film is bonded with the one side of polyethylene outer sheath, another side is bonded with polyisobutene
Waterproofing membrane.
Preferably, described ceramic insulation core is exhausted by aluminium alloy conductor, the first mineral being extruded in outside aluminium alloy conductor
Edge layer, overlapping wrapped double-deck waterstop outside the first mineral insulation and the ceramic SiClx rubber being extruded in outside double-deck waterstop
Adhesive tape is formed.
Preferably, the first described ceramic insulating layer is Ceramic silicon rubber insulating barrier.
Preferably, the second described ceramic insulating layer is Ceramic silicon rubber insulating barrier.
Compared with prior art, the beneficial effects of the present invention are：
1st, more carrying steel cores are provided with cable core so that the not easily broken core of cable, be not easily broken；
2nd, present invention employs multilayer stop water, including, water blocking yarn, waterstop, the polyethylene bonding of aluminium one block water inner sheath etc.,
So that cable has very strong water stop function, the oxidation for causing conductor, corrosion will not be immersed because of moisture, so as to influence cable
Electrical property, or even abnormal broken line accident occurs.
3rd, filling uses water blocking yarn, and water stop function is when meeting water using water blocking yarn fibrous body, can to expand to form body rapidly
(water absorption, such as can be by about 0.5mm in first minute interior diameter for meeting water up to the decades of times of own vol for the very big jelly of product
It is expanded to about 5.0mm rapidly), and the water holding capacity of the jelly is quite strong, the growth of water tree can be effectively prevented, so as to hinder
Sealing point continues to penetrate into and spread, and reaches the purpose to block water.
4th, polyisobutene waterproofing membrane is bonded outside ceramic insulating layer so that cable has high tensile strength, elasticity and prolonged
The features such as stretching big rate, caking property, water-resistance and good weatherability, can be with colod-application, and service life is longer.
5th, provided with double-level-metal screen layer, strengthen effect of the limitation electric field in insulating barrier, make direction of an electric field and insulation half
Footpath direction is consistent（I.e. radially）, metallic shield is with ground, and electric field is terminated on metal tape, and metal tape is outer, and there is no electric field.Prevent
Axial surface discharges, and cable is in the environment of no good earth, because semi-conductive layer has certain resistance coefficient, in cable axle
To that may cause, Potential distribution is uneven, causes cable creeping discharge.In addition, capacitance current is flowed through under normal circumstances, when short-circuit
Metal tape can improve metal screen layer capacitance current and short circuit current transmittability and anti-electricity as the loop of short-circuit current
Magnetic disturbance, the ability for being homogenized electric field.
6th, the inside and outside of the oversheath of cable all plates waterproofing membrane so that the block-water performance of cable greatly improves, and blocking water will
Ask and improve hundred times than prior art water preventing ability.
7th, 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.
Fig. 2 is the structural representation of oversheath of blocking water.
