Abstract
The utility model discloses a high-temperature and high-pressure resistant flexible cable used for oceanographic engineering. The cable comprises cable cores. The cable cores are conductors formed through intertwisting the plurality of nickel plating soft copper wires along a same direction. Peripheries of the conductors are extruded with insulation cores which are formed by insulating layers. The plurality of insulation cores are distributed on a compression resistance layer through plastic extruding molding so as to form the cable cores. A loop of steel wire braiding netting skeleton is arranged in the compression resistance layer. Peripheries of the cable cores are extruded with an integrated waterproof layer, a tin plating steel tape armor layer and a semiconductive water blocking buffer strip layer. A periphery of the semiconductive water blocking buffer strip layer is extruded with an outer sheath. According to the utility model, through arranging the insulation cores in the compression resistance layer, high pressure resistant performance of the cable is increased; simultaneously a water blocking rope, the integrated waterproof layer and the water blocking buffer strip layer are filled so that a high temperature working environment requirement of an offshore oil and gas engineering cable can be satisfied; good waterproof penetration performance is possessed; the cable is widely suitable for the various kinds of oceanographic engineering.
Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of ocean engineering high temperature high voltage resistant flexible cable.
Background technology
Exploitation along with the offshore oil and gas energy; the oil gas engineering is more and more with cable; performance requirement is more and more higher; especially insulation and the metal armouring as cable weight main composition part need to be reduced to greatest extent, needs simultaneously to meet mechanical protection, cable to cable and possesses that the many moisture of the oil gas of adaptation engineering-environment corrodes infiltration and cable can the requirement in useful life of safe operation about 25 years.In prior art, in order to alleviate cable weight, almost all adopt without the inner sleeve cable or adopt the zinc-coated wire braiding to be insulation and sheath as armouring, cross-linking radiation polyolefin, but nonetheless with regard to the supporting angle of integrated engineering, the weight that cable alleviates also is no more than 10%.Prior art adopts the cross-linking radiation polyolefin as insulation, and its thermal endurance class is up to 150 ℃, far can not meet the crosslinked demand of sheath, and the anti-water permeation performance of irradiation crosslinked polyolefin insulating and sheath is very poor, can't meet the Long Term Contact with moisture.For meeting offshore oil and gas engineering cable high-temperature operation environmental requirement, Chinese patent CN201210462773.2 discloses a kind of offshore oil and gas engineering heat-resisting soft power cable and manufacture method thereof, the periphery of zinc-plated annealing twisted copper conductors is extruded with the chemical crosslinking polyolefin insulation layer and forms the power cable insulation core, the edge cores that thoroughly do away with are twisted into cable core more, the cable core periphery is extruded with inner sheath, the inner sheath periphery is coated with copper alloy silk braiding armour, copper alloy silk braiding armour periphery is surrounded with the waterproof band, and waterproof band periphery is extruded with oversheath.The insulating barrier material component is as follows: 12 parts of ethylene/vinyl acetate copolymer; 6 parts of high density polyethylene (HDPE)s; 2 parts of ethylene-methacrylic acid copolymers; Crosslink agent DCP: 0.5～1 part; Antioxidant 1076: 0.4～0.9 part; Antioxidant DNP:0.2～0.4 part; Lubricant stearic acid: 0.2～1 part; Fire retardant aluminium hydroxide: 25～30 parts; Fire retardant red phosphorus: 0.6～1 part; Ultraviolet absorbent uv-326: 0.05～0.1 part.The advantage of this technical scheme is that insulating barrier is high temperature resistant, ageing-resistant performance is excellent, long service life.But it only improves from insulating barrier formula aspect, does not relate to concrete structure, so high temperature high voltage resistant effect not obvious in practical application can not be widely used in all kinds of ocean engineering use, especially block-water performance is not ideal enough, and the scope of application is narrower.
The utility model content
The purpose of this utility model is to provide a kind of ocean engineering high temperature high voltage resistant flexible cable of new construction, it not only can meet offshore oil and gas engineering cable high-temperature operation environmental requirement, and have anti-water permeation performance preferably, can extensively be suitable for the use of all kinds of ocean engineerings.
for realizing this purpose, the technical solution of the utility model is: a kind of ocean engineering high temperature high voltage resistant flexible cable, comprise cable core, described cable core center is by the stranded in the same way conductor that forms of multiply nickel plating soft copper silk, described conductor periphery is extruded with insulating barrier and forms insulated wire cores, a plurality of insulated wire cores are distributed in the resistance to compression layer and form cable core through extrusion moulding, in the resistance to compression layer, also be provided with the webbed skeleton of a circle braided steel wire, the periphery of described cable core is extruded with the Comprehensive Preventing water layer, the periphery of described Comprehensive Preventing water layer is coated with zinc-plated steel band armour, the periphery of described zinc-plated steel band armour is surrounded with the semiconductive buffering belt that blocks water, described semiconductive block water the buffering belt periphery be extruded with oversheath.
As preferably, described cable core also comprises the filler that is filled between each insulated wire cores.
As preferably, described filler consists of the many gasket for packings that block water.
As preferably, described Comprehensive Preventing water layer consists of aluminum plastic composite belt longitudinal covering and polyolefin jacket layer.
With respect to prior art, the utility model gasket for packing that blocks water is a kind of rope shape materials that is composited by polyester fiber, adhesive and rapid expanding water-absorbing resin, meets water and expands rapidly, can stop the further infiltration of water.Wrapped multilayer semiconductive waterstop simultaneously, meeting water can expand rapidly, and entering of blocks moisture effectively extends cable useful life.Adopt simultaneously because aluminium plastic composite material and polyolefine material can waterproof, corrosion-resistant, also have good toughness and insulating properties, so the Comprehensive Preventing water layer is except can by the water resistance gear externally, also having the performance of good anti-electromagnetic interference and anti-mechanical stretching.
