Abstract
The utility model discloses an oil-sludge-resisting signal cable for oil platforms, and the oil-sludge-resisting signal cable belongs to the technical field of cable. The oil-sludge-resisting signal cable comprises a cable core and an outer sheath arranged outside the cable core, and is characterized in that the cable core is formed by twisting two small cables, each small cable is formed by a conductor, a mica tape wrapped on the conductor and an insulating layer extruded on the mica tape, the cable is sequentially provided with a CV belt layer, a copper belt layer, a wrapping belt layer, an inner lining layer and a composite material armor layer which is formed by mixing and weaving Dupont filaments and tinned copper wires, and an outer sheath is blended by EPDM rubber, nitrile rubber and ethylene-viny lacetate resin and is extruded on the composite material armor layer. The oil-sludge-resisting signal cable has the advantages of excellent oil base resistance, water base resistance, low temperature resistance, corrosion resistance, mechanical external force resistance, signal transmission performance and the like.
Description
Technical field
The utility model relates to a kind of structure of cable, and especially a kind of structure of used for oil platform oil resistant mud signal cable belongs to the cable technology field.
Background technology
In recent years, the offshore oil exploitation technical development is rapid, and oil platform quantity also constantly increases, these platforms are seated on the ocean, far apart from land, except being transported some necessitys by cargo ship and helicopter, also need the cable of a large amount of different purposes to support the family, activity in production.Because the special operation environment on the oil platform, life is very harsh with operating condition: solar day photograph ray, sea wind, seawater salt and acid and alkali corrosion, high low temperature, the fire-proof specific (special) requirements on the independent platform and the toxicity of pernicious gas etc.For the used for oil platform cable, oil resistant mud is the difficult problem of cable industry research always.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, thereby provides a kind of oil resistant mud, have the used for oil platform oil resistant mud signal cable of high flame retardant concurrently.
The purpose of this utility model is achieved through the following technical solutions: used for oil platform oil resistant mud signal cable, comprise cable core and be arranged on the outer oversheath of cable core, it is characterized in that, described cable core is formed by two little cable pair twists, little cable is by conductor, wrapped mica tape on conductor, the insulating barrier that is extruded on the mica tape consists of, be provided with successively the CV belt on the described cable core, the copper strips layer, belting layer, inner covering, sheath, the composite material armour, described oversheath is by ethylene propylene diene rubber, acrylonitrile-butadiene rubber, the ethylene-vinyl acetate resin blend is extruded on the composite material armour.
Described composite material armour is made of Du Pont's filament, tinned copper wire mixed weaving.
Described CV belt is provided with drainage thread.
Oversheath of the present utility model can satisfy oil resistant mud and fire resistance, is to have the used for oil platform oil resistant mud signal cable that certain external force resistance impacts.The utility model with the fire retardant (organic and inorganic nucleocapsid structure complex intumescent flame retardant) prepared in conjunction with the compatible modification technology in silane coupler interface, when guaranteeing that oil resistant mud jacket material possesses good oil resistance, have high flame retardant concurrently, to satisfy oil resistant mud and the fire resistance of cable.The composite material armour adopts Du Pont's filament and tinned copper wire mixed weaving armouring, and Du Pont's filament has guaranteed that cable has the effect of certain anti-mechanical external force on the one hand, and tinned copper wire has satisfied again the shielding properties of cable on the other hand.
The utility model is used for offshore platform and carries out the signal transmission, therefore except the screen that must have the normal signal cable (such as copper strips phase-splitting shielding and tinned copper wire braiding armouring), also to consider to be subject to when platform uses the effect of certain mechanical external force at sea, although and common tinned copper wire braiding armouring has certain mechanical strength, the mechanical external force that needs bear when not satisfying cable platform use at sea far away.The oversheath that the utility model adopts is elastomeric material, and the flexibility of elastomeric material is well-known, and the cable of therefore using as platform at sea must be considered reinforced layer.The reinforced layer of rubber cable normally adopts fibrage in the middle of sheath, so as to tearing toughness and other mechanical external force effect that strengthens sheath, if but this cable adopts the fibrage reinforced layer to increase on the one hand the whole cable external diameter, has also increased on the other hand the cables manufacturing operation.Therefore the utility model employing is mixed into the reinforcing fibre silk in the tinned copper wire and weaves together, and the shielding properties that so neither affects cable has increased again the mechanical strength of cable.
Oversheath is in the selection of material, the internal material of this cable and universal cable are as good as, namely adopt the ethylene propylene rubber insulation material of electrical property excellence, but jacket material there is special requirement, as because platform operating environment heavy wool is dirty, contain the flammable explosive gas material, therefore the jacket material of this cable need to possess oil resistant and high flame resistance, and on the other hand cable for a long time in the oil platform operation on the sea, can touch the objects such as seawater, mud, so the jacket material of this cable also must have oil resistant mud performance.The utility model at first prepares ternary polar rubber (ethylene propylene diene rubber, acrylonitrile-butadiene rubber, ethylene-vinyl acetate resin), use the rubber plastic blend technology, the exploitation cable sheath material is developed cable product on this basis, makes product satisfy simultaneously the requirement of oil resistant base, water-fast base, high flexibility; Then adopt aluminium hydroxide, magnesium hydroxide, sulfo-phosphono dihalo-, diphenols organic fire-retardant to prepare organic and inorganic nucleocapsid structure complex intumescent flame retardant, and in conjunction with the compatible modification technology in silane coupler interface, when guaranteeing that oil resistant mud jacket material possesses good oil resistance, have high flame retardant concurrently; And adopt the antioxidant complex technique, and cooperate basis material preferred, make material satisfy simultaneously high low temperature instructions for use.The utlity model has the characteristics such as excellent oil resistant base, water-fast base, low temperature resistant, corrosion resistance, anti-mechanical external force, signal transmission.
