Abstract
The invention relates to the technical field of cable manufacturing, in particular to an oil-sludge-resistant and high-flame-retardant intrinsic safety computer cable for a petroleum platform. The cable comprises four cable cores, wherein a warping cabling layer, a main shield layer, an inner sheath, an armor layer and an outer protection layer are sequentially arranged on the outer sides of the four cable cores; fillers are arranged between the four cable cores and the warping cabling layer; each cable core comprises two pairwise twisted insulating wire cores; warping tape layers and subitem shield layers are sequentially arranged on the outer sides of the pairwise twisted insulating wire cores; each insulating wire core comprises a conductor; and insulating layers are wrapped on the outer sides of the conductors. The cable is reasonable and novel in structure, and scientific and particular in material, has the characteristics of low capacity, low inductance, difficult electric spark generation and intrinsic safety, and has excellent flame retardance, interference resistance, wear resistance, oil sludge resistance, oil resistance, ozone resistance and the like.
Description
Technical field
The present invention relates to cables manufacturing technical field, particularly a kind of used for oil platform oil resistant mud high flame retardant intrinsic safety computer cable.
Background technology
Be accompanied by global energy exploitation to the transfer of ocean, marine oil and gas engineering is in the ascendant.The explored petroleum-in-place of South China Sea is 23,000,000,000 tons, is called as the Chinese Persian Gulf, but marine site, this area is darker, and deep water platform is manufactured core technology and abroad monopolized again, has seriously restricted the oil development utilization at China South Sea.In recent years, along with China's autonomous Design and research and development the 6th generation deep water platform lower water, the technology that indicates domestic construction large-sized deep water platform is ripe, and supporting with it used for oil platform computer cable has also been proposed to very high specification requirement.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 oil resistant mud high flame retardant intrinsic safety computer cable supporting with it.Therefore, research and development oil resistant mud high flame retardant intrinsic safety computer cable, imperative.
Summary of the invention
The object of the present invention is to provide that a kind of cable shield is effective, the used for oil platform oil resistant mud high flame retardant intrinsic safety computer cable of oil resistant, resistance to mud.
The present invention includes four groups of cable cores, in described four groups of cable cores outside, set gradually wrapped stranding layer, total screen, inner sheath, armour and outer jacket; Between described four groups of cable cores and wrapped stranding layer, filling is set; Described every group of cable core comprises respectively the insulated wire cores of two pair twists, in the insulated wire cores outside of described pair twist, sets gradually belting layer and subitem screen; Described every insulated wire cores comprises respectively conductor, wrap insulate layer outside described conductor.
Conductor of the present invention adopts the stranded bunchy of several tinned copper wires to form, and cross-sectional area of conductor amasss as 0.75-2.5mm
2; Insulating material is crosslinked polyethylene, and separated-shielding adopts the overlapping wrapped mode of aluminium-plastic tape, and total shielding is wrapped aluminum foil polyester composite strip outside cable core; In screen, place one by the stranded drainage thread of multiply tinned copper wire, drainage thread need contact with the aluminium lamination of aluminium-plastic tape; Inner sheath, oversheath adopt oil resistant mud cross-linking low-smoke halogen-free polyolefin to extrude formation.Armour adopts tinned copper wire braiding to form, and count is not less than 90%.The present invention's novelty rational in infrastructure, materials science is particular about, and has low electric capacity, low inductance, is difficult for producing electric spark, essential safety characteristic; There is the premium properties such as fire-retardant, anti-interference, wear-resisting, oil resistant mud, oil resistant, resistance to ozone simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes four groups of cable cores 1, in described four groups of cable core 1 outsides, set gradually wrapped stranding layer 2, total screen 3, inner sheath 4, armour 5 and outer jacket 6; Between described four groups of cable cores 1 and wrapped stranding layer 2, arrange and fill 7; Described every group of cable core 1 comprises respectively the insulated wire cores 8 of two pair twists, sets gradually belting layer 9 and subitem screen 10 in insulated wire cores 8 outsides of described pair twist; Described every insulated wire cores 8 comprises respectively conductor 11, at described conductor 11 outside wrap insulate layers 12.
