Abstract
The utility model relates to a cable, in particular to a metal sheath type cable for an oil platform. The metal sheath type cable for the oil platform comprises a cable core, wherein a sealed metal sheath (9) is longitudinally wrapped outside the cable core, and an outer sheath (10) is wrapped outside the metal sheath (9) in squeezing mode. The metal sheath type cable has the advantages of being capable of effectively reducing sea water corrosion on conductors by adopting the conductor made of tin-plating copper, enabling the bending radius required by cables to be smaller by adopting cabling pitches greatly lower than standard requirements, and being capable of greatly improving compression resisting performance and waterproof performance by adopting seamlessly-welded aluminum sheathes, copper sheathes, stainless steel sheaths or lead sheathes wrapped in squeezing mode as the metal sheath.

The utility model content
The technique effect of the utility model can overcome above-mentioned defective; A kind of metallic sheath type oil platform cable is provided; It is satisfying on the basis of production platform environment to the cable requirement, adopt metallic sheath as the shield layer of platform cable improved greatly cable mechanical strength, waterproof ability, improved the short circuit current maximum and the antijamming capability that allow
For realizing above-mentioned purpose, the utility model adopts following technical scheme: it comprises cable core, the metallic sheath of the vertical outward bag sealing of cable core, and metallic sheath extrudes oversheath outward.
Be provided with inner sheath between cable core and the metallic sheath.
Cable core adopts power cable or control cable or instrument cable or telecommunication cable or communications optical cable or its combination.
Cable core is provided with one at least.Water blocking layer is filled in gap between the cable core, is provided with the stranding lapping layer between water blocking layer and the inner sheath.
In the technical scheme of the utility model; Conductor in the cable core is a copper conductor; Copper conductor comprises two kinds of bare copper conductor and tin-coated copper conductors; Insulating layer material is crosslinked polyethylene (XLPE) or ethylene-propylene rubber (EPR), and conductor screen and insulation shielding material are the corresponding semiconductive material of this electric pressure, and the phase-splitting metallic shield is forms such as the wrapped or copper wire braiding of copper strips; Inner sheath and jacket material can be polyvinyl chloride (PVC), polyethylene (PE), halogen-free and low-smoke flame-retardant polyolefin (PO), chlorosulfonated polyethylene (CSM) etc., and said metallic sheath can be aluminium sheath, copper sheath, the stainless steel sheath of seamless welding or the lead sheath that extrudes; Said conductor is a copper conductor in control and the instrument cable; Copper conductor is divided into two kinds of bare copper conductor and tin-coated copper conductors; Said insulating layer material is crosslinked polyethylene (XLPE); Set of shield can be copper wire braid shielded, copper strips shielding and the shielding of plastic-aluminum band with total shielding in said minute; Said inner sheath and jacket material can be polyvinyl chloride (PVC), polyethylene (PE), halogen-free and low-smoke flame-retardant polyolefin (PO), and said metallic sheath can be aluminium sheath, copper sheath, the stainless steel sheath of seamless welding or the lead sheath that extrudes.
The beneficial effect of the utility model patent is: adopt the tin-coated copper conductor can effectively reduce the corrosion of seawater to conductor; It is littler that employing is lower than the bending radius that behind the more laying up pitch of standard-required cable is allowed; The lead sheath that adopts aluminium sheath, copper sheath, the stainless steel sheath of no seam welding or extrude can improve anti-pressure ability, the water resistance of cable to a great extent as the metallic sheath of cable, and the metal sheath layer of power cable and ground connection core are connected to the ability that can improve cable carrying short circuit current behind the equipment to a large extent; The metal sheath layer of control and instrument cable can make the shield effectiveness of cable better after being connected to equipment with branch set of shield and total shielding.
