Abstract
A water-repellent oil-resistance cable used for an oil platform essence security system includes a cable core and an outer jacket; a plurality of lead groups are arranged in the cable core; the outside of each lead group is in turn coated with an individually shielded isolating layer and an individually shielded layer to form a signal transmission unit; a collectively shielded isolating layer, a collectively shielded layer, an inner inflaming retarding protective layer, a reinforcing layer and a water-proof layer are coated in turn between the cable core and the outer jacket; the water-repellent oil-resistance cable of the utility model has the advantages of small attenuation for transmitting signals, excellent shielding property, high intensity, high inflaming retarding property and good water-proof oil-resistance effect.
Description
Technical field
The utility model relates to a kind of signal-transmitting cable, especially the signal cable used of oil platform intrinsic safety system.
Background technology
Existing offshore oil platform is bigger with the signal cable transmission attenuation, and shield effectiveness is relatively poor, and the oil resistance that blocks water is low, and insufficient strength is difficult to adapt in the environment of operation at sea and uses.
Summary of the invention
It is little that the purpose of this utility model provides a kind of transmission attenuation, and shield effectiveness is good, and the high oil platform intrinsic safety system of intensity is with the oil resistant cable that blocks water.
The oil platform intrinsic safety system that the utility model provides comprises cable core and oversheath with the oil resistant cable that blocks water, in cable core, have several lead groups, each lead group coats outward successively divides shielding separator, sub-shield to constitute signal transmission unit, coats total shielding separator, total screen, reinforced layer, water blocking layer between cable core and oversheath successively.
In order to strengthen fire resistance of the present utility model, between total screen and reinforced layer, be provided with fire-retardant sheath.
The beneficial effects of the utility model are: the transmission signals decay is little, and shielding properties is excellent, the intensity height, and fire resistance is strong, and the oil resistant that blocks water is effective.
Description of drawings
Fig. 1 is a cross sectional representation of the present utility model.
In Fig. 1,1, conductor, 2, insulating barrier, 3, divide the shielding separator, 4, sub-shield, 5, the sub-shield drainage thread, 6, total screen drainage thread, 7, always shield separator, 8, total screen, 9, fire-retardant sheath, 10, reinforced layer, 11, water blocking layer, 12, oversheath, 13, lead group, 14, signal transmission unit, 15, cable core.
Embodiment
With reference to Fig. 1, make signal transmission unit 14 earlier, adopt the stranded poly-second polyolefin insulation layer 2 of lead 1 back outsourcing of making of multiply tinned copper wire, with per three leads is a lead group 13, outsourcing sub polyethylene shielding separator 3 and aluminium-plastic tape sub-shield 4 also is provided with sub-shield drainage thread 5 formation signal transmission units 14, then several signal transmission units 14 are twisted into cable core 15, coating polyethylene outside cable core 15 successively always shields separator 7 and the total screen 8 of aluminium-plastic tape and total screen drainage thread 6 is set, coat polyethylene anti-flaming sheath 9 more successively, reinforced layer 10 with braided steel wire, the water blocking layer 11 that waterstop constitutes, with the oversheath 12 that the LSOH anti-flaming protective cover material is made, promptly make the utility model.
Claims (2)
1, a kind of oil platform intrinsic safety system is with the oil resistant cable that blocks water, comprise cable core and oversheath, it is characterized in that in cable core, having several lead groups, each lead group coats outward successively divides shielding separator, sub-shield to constitute signal transmission unit, coats total shielding separator, total screen, reinforced layer, water blocking layer between cable core and oversheath successively.
2, by the described oil platform intrinsic safety system of claim 1 with the oil resistant cable that blocks water, it is characterized in that between total screen and reinforced layer, being provided with fire-retardant sheath.
