CN203276890U - Oil-sludge-resistant and high-flame-retardant intrinsic safe computer cable for oil platform - Google Patents

Abstract

The utility model relates to the cable manufacture technology field, and especially relates to an oil-sludge-resistant and high-flame-retardant intrinsic safe computer cable for an oil platform. The cable comprises four cable cores; a wrapping cabling layer, a main shielding layer, an inner sheath, an armor layer and an outer protection layer are sequentially arranged outside the four cable cores; filling is carried out between the four cable cores and the wrapping cabling layer; each of the four cable cores comprises two intertwisting insulating cores; a wrapping tape layer and a partial shielding layer are sequentially arranged outside the two intertwisting insulating cores; and each of the insulating cores comprises a conductor which is wrapped by an insulating layer. The oil-sludge-resistant and high-flame-retardant intrinsic safe computer cable for the oil platform has the characteristics of reasonable and novel structure, scientific and careful material adoption, low capacitance and inductance, little electric spark, and safety in essence, and also has such advantages as the flame retardation, anti-interference, wear resistance, oil sludge resistance, oil resistance, and ozone resistance.

Description

Used for oil platform oil resistant mud high flame retardant intrinsic safety computer cable

Technical field

The utility model relates to the 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 the global energy exploitation to the transfer of ocean, the marine oil and gas engineering is in the ascendant.The explored petroleum-in-place of South China Sea is 23,000,000,000 tons, be called as the Persian Gulf of China, but the marine site, this area is darker, and deep water platform is made 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 very high specification requirement.Owing to being full of inflammable and explosive greasy dirt and gas in the 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 purpose of this utility model 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, anti-mud.

The utility model comprises four groups of cable cores, sets gradually wrapped stranding layer, total screen, inner sheath, armour and outer jacket outside described four groups of cable cores; 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, sets gradually belting layer and subitem screen outside the insulated wire cores of described pair twist; Described every eradication edge core comprises respectively conductor, wrap insulate layer outside described conductor.

The utility model conductor adopts the stranded bunchy of several tinned copper wires to consist of, and cross-sectional area of conductor is long-pending is 0.75-2.5mm ²Insulating 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; Place one in screen by the stranded drainage thread of multiply tinned copper wire, drainage thread needs to 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 the tinned copper wire braiding to form, and count is not less than 90%.The utility model novelty rational in infrastructure, the materials science is particular about, and has low electric capacity, low inductance, is difficult for producing electric spark, essential safety characteristic; Have simultaneously the premium properties such as fire-retardant, anti-interference, wear-resisting, oil resistant mud, oil resistant, anti-ozone.
