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 will all show shallow water cable huge demand.Due to the particular surroundings of bottom of shallow sea application, cable is needed to have
Have different conductive sections, different mechanical strengths, anti-seawater leakage with corrosion etc. architectural characteristics, 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, providing one kind has tensile strength high, and elasticity and elongation percentage are big, viscous
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 utility model provides a kind of double sheath flexible water electric power electricity of ceramic insulation double shield
Cable, including cable core, the cable core it is twisted by more ceramic insulation cores and with the same number of steel core of ceramic insulation core and
At in cable core gap equipped with water blocking yarn, the wrapped waterstop outside cable core extrudes one polyethylene bonding of aluminium outside waterstop and blocks water
Inner sheath blocks water in one polyethylene bonding of aluminium and extrudes the second ceramic insulating layer outside inner sheath, is bonded outside ceramic insulating layer poly- different
Butylene waterproofing membrane first weaves steel band shielded layer outside polyisobutene waterproofing membrane, then weaves aluminium strip shielded layer, is shielded in steel band
Layer is externally provided with separation layer with aluminium strip shielded layer, and the oversheath that blocks water is extruded outside aluminium strip shielded layer；In the oversheath that blocks water
Interbed is polyethylene outer sheath, is bonded with polyurethane water-proof film on one side in polyethylene outer sheath, another side is bonded with poly- different
Butylene waterproofing membrane.
Preferably, the ceramic insulation core is exhausted by aluminium alloy conductor, the first ceramics being extruded in outside aluminium alloy conductor
Edge layer, the ceramic SiClx rubber for being overlapped the double-deck waterstop outside the first ceramic insulating layer and being extruded in outside the double-deck waterstop
Adhesive tape is constituted.
Preferably, first ceramic insulating layer is Ceramic silicon rubber insulating layer.
Preferably, second ceramic insulating layer is Ceramic silicon rubber insulating layer.
Compared with prior art, the beneficial effects of the utility model are：
1, more carrying steel cores are equipped in cable core so that the not easily broken core of cable is not easily broken；
2, the utility model uses multilayer stop water, including water blocking yarn, waterstop, one polyethylene bonding of aluminium block water
Inner sheath etc. so that cable has very strong water stop function, and the oxidation for causing conductor, corrosion will not be immersed because of moisture, to
The electrical property of cable is influenced, or even is abnormal line-outage contingency.
3, it is that when meeting water using water blocking yarn fibrous body, can expand to form body rapidly that filling, which uses water blocking yarn, water stop function,
The prodigious jelly of product (water absorption up to own vol decades of times, such as first minute interior diameter of chance water can be by about 0.5mm
It is expanded to about 5.0mm rapidly), and the water holding capacity of the jelly is quite strong, can effectively stop the growth of water tree, to hinder
Sealing point continues to penetrate into and spread, and achievees the purpose that block water.
4, polyisobutene waterproofing membrane is bonded outside ceramic insulating layer so that cable has high tensile strength, elasticity and prolongs
The features such as stretching big rate, caking property, water-resistance and good weatherability, can be colod-application, and service life is longer.
5, it is equipped with double-level-metal shielded layer, reinforces effect of the limitation electric field in insulating layer, makes direction of an electric field and insulation half
Diameter direction is consistent（It is i.e. radial）, metallic shield is with ground, and electric field terminates on metal tape, and metal tape is outer, and there is no electric fields.It prevents
Axial surface discharges, and cable is in the environment of not good earth, since semi-conductive layer has certain resistance coefficient, in cable axis
To Potential distribution may be caused uneven, cable creeping discharge is caused.In addition, capacitance current is flowed through under normal circumstances, when short-circuit
Metal tape can be used as the circuit of short-circuit current, improve metal screen layer capacitance current and short circuit current transmittability and anti-electricity
Magnetic disturbance, the ability for being homogenized electric field.
