Description
Technical field
The invention belongs to field of cable technology, be specifically related to a kind of high strength intrinsically-safe instrument cable.
Background technology
Along with the transfer of global energy exploitation to ocean, marine oil and gas engineering is in the ascendant.Owing to being full of inflammable and explosive greasy dirt and gas in marine oil and gas engineering, for guaranteeing the fail safe of electric signal transmission in equipment, need special intrinsically-safe instrument cable supporting with it.Because the topmost performance of ocean engineering essential safety instrument cable is low electric capacity and low inductance, and electric capacity is multifactor relevant with conductor material, insulating material, insulation thickness, twisting pitch etc. with inductance.Design must consider the interference of interference and outer bound pair cable mutually between each pair twist group of cable.The high risk sexual of oil gas of ocean engineering injection simultaneously requires cable low-smoke non-halogen flame-retardant, and especially intrinsically-safe instrument cable must meet even fire-retardant higher than category-A bunchy regulation especially.Meanwhile, the intensity of most of intrinsically-safe instrument cable is poor, easily breaks down.
Summary of the invention
The object of the present invention is to provide a kind of high strength intrinsically-safe instrument cable of new construction, it has low electric capacity and low inductance and high shielding properties and high strength, with applicable field of ocean engineering to cabling requirements.
For realizing this purpose, technical scheme of the present invention is: a kind of high strength intrinsically-safe instrument cable, comprise into cable core, the wrapped laminated polyester film of described one-tenth cable core, the outer wrapped aluminum foil polyester composite strip of described polyester film, the grounding lead streamline that a tinned copper wire is stranded is accompanied in described aluminum foil polyester composite strip, drainage thread contacts with the aluminium lamination of aluminum foil polyester composite strip, inner covering is provided with outside described aluminum foil polyester composite strip, tincopper fuse wire braided armor is provided with outside described inner covering, composite jacket is provided with outside described woven shield, described composite jacket wall thickness middle position is provided with two and is parallel to each other and the high-tensile steel wires arranged along cable longitudinal direction.
As preferably, in described one-tenth cable core, four groups of conductors are that star is uniform, often group conductor is twisted again by multiply tinned copper wire and forms, it extrudes low-density crosslinked polyetylene insulated, wrapped laminated polyester film, the outer wrapped aluminum foil polyester composite strip of described laminated polyester film, accompany the grounding lead streamline that a tinned copper wire is stranded in described aluminum foil polyester composite strip, drainage thread contacts with the aluminium lamination of aluminum foil polyester composite strip.
As preferably, containing fibre bundle strengthening core in the conductor of described power wire core.
As preferably, described composite jacket is made up of the wrinkle composite steel-plastic belt moisture-proof layer and black polyethylene sheath indulging bag overlap joint.
As preferably, inside described composite jacket, be also provided with a circle braided steel wire webbed skeleton resistance to compression layer.
Relative to prior art, the present invention weaves dual composite barrier structure by aluminum foil polyester composite strip and tinned wird, greatly can improve the shielding properties of cable, reach the effect of getting twice the result with half the effort.Oversheath is made up of the wrinkle composite steel-plastic belt moisture-proof layer and black polyethylene sheath indulging bag overlap joint, thereafter low temperature resistantly-40 DEG C are reached, and possess wear-resisting, anti-tear, the performance such as oil resistant, resistance to ozone, resistance to greasy filth, high flame retardant, the requirement of the many corrosion of offshore engineering equipment environment can be met.In addition, arrange in the wall thickness central authorities of composite jacket and form tension member by the high-tensile steel wires of two parallel placements, contribute to promoting cable strength, can play a protective role to cable when cable bears larger pulling force.Meanwhile, inside sheath, be provided with a circle braided steel wire webbed skeleton resistance to compression layer, improve the tensile and compressive property of cable further.
