Abstract
The invention discloses a kind of cable used in offshore oil engineering, including cable core and sheath, described cable core is formed by some insulated wire cores are stranded, cable core periphery wrapped fire resisting isolation strip, fire resisting isolation strip periphery arranges rubber strap lapping layer, rubberized tape lapping layer periphery arranges inner sheath, and inner sheath is externally provided with zinc-coated wire double braid armor, arranges chlorosulfonated polyethylene oversheath outside zinc-coated wire double braid armor.Present configuration is simple, shielding is good, soft, fire resisting, resistance to mud.
Description
Technical field
The present invention relates to a kind of cable is and in particular to a kind of cable used in offshore oil engineering.
Background technology
The cable that existing offshore engineering equipment is used, because being related to the many mud in ocean water bottom, heavy wool, high and low difference variation etc. adverse circumstances, the cable using in the present context is needed with high- and low-temperature resistance, waterproof, fire-retardant, fire prevention, weather-resistant, flexibility is good, easy to use, the features such as safe and reliable；And the cable that existing offshore engineering equipment is used is still traditional common cable, therefore it is serious to there is cable corrosion, service life is short, bring frequently maintenance, maintenance task to the just engineering equipment in operation, cause production plan cannot be timely completed, cause huge economic loss, hinder the development of defence engineering construction.
Accordingly, it would be desirable to a kind of new cable used in offshore oil engineering.
Content of the invention
It is an object of the invention to provide a kind of cable used in offshore oil engineering, structure is simple, shielding is good, soft, fire resisting, resistance to mud.
The purpose of the present invention is achieved through the following technical solutions, a kind of cable used in offshore oil engineering, including cable core and sheath, described cable core is formed by some insulated wire cores are stranded, cable core periphery wrapped fire resisting isolation strip, fire resisting isolation strip periphery arranges rubber strap lapping layer, and rubberized tape lapping layer periphery arranges inner sheath, inner sheath is externally provided with zinc-coated wire double braid armor, arranges chlorosulfonated polyethylene oversheath outside zinc-coated wire double braid armor.
Preferably, the gap filling between described insulated wire cores has the dimity.
Preferably, described inner sheath is oxygen barrier Halogen inner sheath.
Preferably, described oxygen barrier Halogen inner sheath selects halogen-free polyolefin material.
Preferably, described fire resisting isolation strip is mica tape.
Compared with prior art, the invention has the advantages that：
First, inner/outer sheath structure makes cable oil resistant, breakage resistant luer, heat-resisting, low temperature resistant, corrosion-resistant, light shine, moisture-proof, especially resistance to mud；The inner/outer sheath preferably cross-linked polyolefin of resistance to mud rubber, makes the resistance to mud of cable, fire-retardant, low smoke and zero halogen and low toxicity, oil resistant, breakage resistant luer, heat-resisting, low temperature resistant, corrosion-resistant, light shine, moisture-proof further；
Second, fire resisting isolation strip, on the premise of insulated conductor and insulating barrier, effectively improves fire resistance；Its preferred mica tape improves anti-flammability further；
3rd, the present invention has the advantages that structure is simple, shielding is good, soft, fire resisting, resistance to mud.
Brief description
Fig. 1 is the overall structure diagram of cable used in offshore oil engineering of the present invention；
In figure：1 insulated wire cores, 2 fire resisting isolation strip, 3 rubber strap lapping layers, 4 inner sheaths, 5 zinc-coated wire double braid armors, 6 chlorosulfonated polyethylene oversheaths.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and detailed description:
As shown in Figure 1, a kind of cable used in offshore oil engineering, including cable core and sheath, described cable core is formed by some insulated wire cores 1 are stranded, cable core periphery wrapped fire resisting isolation strip 2, fire resisting isolation strip periphery arranges rubber strap lapping layer 3, and rubberized tape lapping layer periphery arranges inner sheath 4, inner sheath is externally provided with zinc-coated wire double braid armor 5, arranges chlorosulfonated polyethylene oversheath 6 outside zinc-coated wire double braid armor.
Preferably, the gap filling between described insulated wire cores has the dimity.
Preferably, described inner sheath is oxygen barrier Halogen inner sheath.
Preferably, described oxygen barrier Halogen inner sheath selects halogen-free polyolefin material.
Preferably, described fire resisting isolation strip is mica tape.
Inner/outer sheath structure of the present invention makes cable oil resistant, breakage resistant luer, heat-resisting, low temperature resistant, corrosion-resistant, light shine, moisture-proof, especially resistance to mud；The inner/outer sheath preferably cross-linked polyolefin of resistance to mud rubber, makes the resistance to mud of cable, fire-retardant, low smoke and zero halogen and low toxicity, oil resistant, breakage resistant luer, heat-resisting, low temperature resistant, corrosion-resistant, light shine, moisture-proof further；
Fire resisting isolation strip of the present invention, on the premise of insulated conductor and insulating barrier, effectively improves fire resistance；Its preferred mica tape improves anti-flammability further；
The present invention has the advantages that structure is simple, shielding is good, soft, fire resisting, resistance to mud.
