Abstract
The invention discloses a fireproof control and instrument cable for an offshore oil platform. Conductors are formed by bundling and intertwisting tinned soft copper wires, each conductor is wrapped by two layers of alloy mica tapes to form a fireproof layer, and a polyolefin insulating layer is extruded on the fireproof layer and irradiation crosslinking is performed so as to form an insulated wire core; two insulated wire cores are twisted in pair and wrapped by a polyester belt layer and an aluminum plastic composite belt sub-shielding layer to form a shielding core, a plurality of shielding cores form a cable core, and the cable core is internally filled with flame0retardant filling ropes; and the cable core is provided with a second fireproof layer, an inner sheath layer, an armor layer, an outer sheath layer and a sheath layer from inside to outside. According to the fireproof control and instrument cable for the offshore oil platform, maintenance of excellent insulating performance of the cable under a circumstance of high-temperature combustion is improved, so that the cable can operate normally for hours at 1000 DEG C, and can satisfy requirements for fire protection and of extremely severe environment.
Description
technical field
The present invention relates to a kind of cable, particularly offshore oil platform is controlled and instrument cable with fire prevention, belongs to technical field of electric wires and cables.
Background technology
Along with scientific and technical development, to requiring also more and more higher with the cable of marine equipment.Conventionally flame retardant cable used is substantially all to adopt flame retardant insulation material, fire-retardant band, flame-retardant filler, flame-retardant sheath material.Its deficiency is: in the time of breaking out of fire, cable stops the performance of propagation of flame not strong, and flame easily spreads to insulating barrier.Boats and ships and personnel's safety is caused to very large hidden danger.The heaviness loss that fire brings to human society is serious.This just requires fire-resisting cable in flame combustion situation, still can keep maintaining operation in certain hour, so that circuit is unimpeded, and alarm, traffic light system guiding, evacuates the masses, and makes Fire lift, water pump and the fume extractor can continuous service in the state of accident.
Summary of the invention
The object of the invention is to provide the fire prevention of a kind of offshore oil platform to control and instrument cable, can in high-temp combustion situation, still can keep good insulation property, can operation continuously in thermal-flame.
The solution of the present invention is as follows: a kind of offshore oil platform is controlled and instrument cable with fire prevention, conductor adopts the soft tow strand of tin-coated copper, on described conductor, wrapped two-layer alloy mica tape composition fireprotection layer, adopts cross-linking radiation to extrude polyolefin insulation layer and forms insulated wire cores on described fireprotection layer; After two pairs of insulated wire cores pair twists, wrapped polyester belt and aluminium-plastic tape sub-shield form shielding core, and the stranded formation cable core of multipair shielding core is filled fire-retardant gasket for packing in described cable core; The second fireprotection layer, inner restrictive coating, armour, external sheath layer, restrictive coating are set respectively on described cable core from inside to outside.
The second described fireprotection layer is made up of two laminated phlogopite.
Described inner restrictive coating and jacket layer all adopt the low cigarette polyolefin of irradiation crosslinking halogen-free to extrude moulding.
Described restrictive coating adopts thermoplasticity fire prevention polyolefine material to extrude moulding.
Beneficial effect of the present invention:
1, the present invention has aluminium-plastic tape separated-shielding and the total shielding construction of proof copper-wire braided, and count is greater than 90%, and separated-shielding and always shielding, be to have adopted two kinds of different shielding materials, plays certain complementation on electromagnetic wave shielding, and shield effectiveness will be better.
2, the present invention extrudes one deck thermoplastic halogen-free fire prevention polyolefin jacket material in oversheath outside, can effectively prevent the burning of flame, improves fireproofing of cable performance.
3, conductor of the present invention and cable core wrapped double-layer alloy mica tape respectively, improves fireproofing of cable performance, extends cable useful life.
4, after cable fire of the present invention, mica is fully sintered on copper cash, forms a layer insulating, has certain mechanical strength and water-fast, can keep like this cable normal operation a few hours in the time of 1000 DEG C, can meet the requirement of fire-fighting and extreme severe rugged environment.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Wherein: 1 conductor, 2 fireprotection layers, 3 insulating barriers, 4 polyester belts, 5 screens cover, 6 fire-retardant gasket for packings, 7 second fireprotection layers, 8 inner restrictive coatings, 9 armours, 10 external sheath layers, 11 restrictive coatings.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
One offshore oil platform is controlled and instrument cable with fire prevention, and its tinned copper conductor 1 adopts restraints the structure that tangles, the fireprotection layer 2 of wrapped two-layer alloy mica tape composition on conductor 1, and polyolefin insulation layer 3 is extruded on fireprotection layer 2, and adopts cross-linking radiation; Two pairs of insulated wire cores pair twists, and wrapped polyester belt 4 and aluminium-plastic tape sub-shield 5, then the pair twist core of multipair separated-shielding twists together simultaneously that fire-retardant gasket for packing 6 is full of gap and wrapped two-layer alloy mica tape forms the second fireprotection layer 7; Inner restrictive coating 8 adopts the low cigarette polyolefin of irradiation crosslinking halogen-free to be extruded in moulding on the second fireprotection layer 7, the outer setting of inner restrictive coating 8 adopts metal knitted armour 9, external sheath layer 10 adopts the low cigarette polyolefin of irradiation crosslinking halogen-free to be extruded in moulding on armour 9, extrudes one deck thermoplasticity fire prevention polyolefin jacket layer 11 on external sheath layer 10.The present invention has improved cable and in high-temp combustion situation, has kept good insulation property, can keep like this cable normal operation a few hours in the time of 1000 DEG C, can meet the requirement of fire-fighting and extreme severe rugged environment.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection scope of the present invention.
