Description
Technical field
The utility model belongs to electric wire field, relates in particular to a kind of cross-linked polyethylene insulated cable.
Background technology
China's coastline total length surpasses 1.8 ten thousand km, more than 5000, island, from world wide, the length in coastline and quantity more greatly, more.Exhaustion and the increase of the mankind to electricity needs along with global fossil energy, human production activity moves towards ocean gradually, as exploitation of offshore wind turbine generating, ocean tidal power, ocean natural gas and oil etc., and the approach that obtains the energy only has one, and that is exactly submarine cable.China's cables manufacturing scale in 2012 surpasses the U.S. becomes global the first cables manufacturing state, but quite a few high-end product is as XLPE insulation 500kv ultrahigh voltage power cable, the most of dependence on import of seabed, superhigh pressure heavy in section AC/DC power cable.Held Chinese wires and cables industry conference in September, 2012 in Shanghai, can going up the materials such as DOW Chemical, Borealis, French Bo Diya, German Treister and equipment supplier, to mention maximum words be exactly " submarine cable ".
Existing nearly 170 years history is researched and developed, produced, lays to submarine cable, between Britain in 1850 and France, laid article one submarine cable in human history; Article one submarine cable of China is to complete in 1888, has two, the one, and between river, Foochow stone island and Shanghai, Taiwan tail, the flat Penghu that leads to of another Tiao Youtai Nanan, organizes and lays by Taiwan governor of a province Liu Mingchuan at that time.The dividing and have by class of insulation of submarine cable: dipping paper bag insulated cable, oil-filled cable, squash type cable (XLPE--is crosslinked polyetylene insulated ethylene propylene rubber insulated with EPR--), the insulation of dipping paper bag and oil-filled cable are subject to the depth of water and lay drop to limit, now substantially superseded.What use was extensive, the most maximum at present is XLPE insulated cable.
Abroad submarine cable is researched and developed, produces, lays and is safeguarded and formed standardized work, and submarine cable key technology is external shield and the extruding of insulation zero defect in the cable of big-length sea, combines stranding, connecting hose and fiber unit structural research (composite sea cable).In recent years, China greatly develops offshore wind farm and oil gas project, need a large amount of submarine cable transferring electric powers and communicate by letter, this has injected potion good recipe just to weak Chinese line cable industry, the <2012 South China Sea deep water hydrocarbon drilling and extracting equipment and the technical seminar > that in Beijing, hold in November, 2012 have transmitted an information, and China's exploitation marine resources are extremely urgent.
Domestic submarine cable industry is scarcely out of swaddling-clothes at present, that structural design or technique manufacture all have a lot of defects, at present conventional submarine cable structure is a kind of crosslinked polyetylene insulated multicore submarine cable as Chinese patent 201320365348.1 discloses, comprise by three stranded cable cores that form of insulated wire cores, the gap of cable core is provided with packed layer, at cable core, wrap up successively copper braided fiber band, lead sheath, inner covering, armour outward, at cable outermost layer, extrude outer jacket; In armour, place and there are centrosymmetric four fiber units.Described insulated wire cores consists of conductor and the insulating barrier, the insulation screen that are extruded in outside conductor.Described fiber unit is to consist of optical fiber and the optical fiber armoured layer that is coated on outside optical fiber.If the cable of this structure is arranged on shallow sea, performance index problem is little, but is mounted in deep-sea, because the pressure of seawater and the impulse force of seawater all can increase a lot, requirement for cable is also just higher, and the cable of current this structure is difficult to guarantee normally to work at deep-sea.
Summary of the invention
The utility model provides a kind of cross-linked polyethylene insulated cable, to solve the problem that cannot normally work at deep-sea proposing in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions: the utility model provides a kind of cross-linked polyethylene insulated cable, it is characterized in that: comprise the inner sheath of socket successively, inner armor layer, armoured layer, oversheath, in described inner sheath, be provided with optical fiber component, described inner sheath inside is provided with the copper conductor that blocks water, the described copper conductor outside that blocks water is overlapped and is had internal layer semiconductor water blocking layer successively, crosslinked polyetylene insulated layer, outer semiconductor water blocking layer, swellable tape, copper strip shielding layer, plumbous watertight composition processed, conductor shield, bitumen layer, conductor sheath, between described inner sheath and described conductor sheath, be provided with inorfil filler, the outer surface cover of described oversheath has bearing, described bearing comprises internal axle sleeve, outer shaft, be arranged at described internal axle sleeve, interlayer cover between outer shaft, described interlayer cover lateral wall is provided with elongated slot, in described elongated slot, be provided with ball.
The quantity of described elongated slot is 8, and is symmetrical arranged.
The quantity of described elongated slot is 4, and is symmetrical arranged.
The beneficial effects of the utility model are: the utility model arranges bearing in the outside of oversheath, can resist the pressure of deep sea water, cable internal structure is not damaged, in bearing inside, spin is set, the rotation that can misplace of outer shaft and interlayer cover, under sea washes, outer shaft is stressed to be rotated, the impulse force of seawater is weakened, avoided cable directly stressed, it is produced and is damaged, at interlayer, put elongated slot is set, ball is arranged in elongated slot, can reduce the quantity of ball, both reached the object of outer shaft rotation, can reduce costs again, in arranging, outer double armo(u)ring layer, can strengthen the hardness of cable, the internal structure of protection cable, by two-layer semiconductor water blocking layer is set, can strengthen the waterproof effect of the inside of cable, screen adopts copper strips, can extend screen useful life, due to seabed easy-maintaining not, although cost is higher, but maintenance cost can be much lower, swellable tape is to put overlong time owing to soaking in seawater, the material of cable all can have some water absorptions to expand, thereby deform, the effect of swellable tape is mainly the change in volume that guarantees cable, thereby guarantee the normal use of cable.
