Abstract
The invention discloses a cable for a petroleum platform, which relates to the technical field of cables, provides a cable for a petroleum platform, and aims at providing a cable for a petroleum platform, which is good in tension resistance and soft. The cable comprises a central reinforcing steel wire (1) and four conductors (2), wherein an insulation layer (3) wraps outside each of the conductors (2); a shielding layer (4) wraps outside the insulation layer (3); an inner sheath layer (4) wraps outside the shielding layer (4); an asphalt layer (6) wraps outside the inner sheath layer; a tensioner (7) is arranged in the asphalt layer (6); an outer sheath layer (8) is arranged outside the asphalt layer (6); a filling material (9) is arranged between the insulation layer (3) and the shielding layer.
Description
Technical field
The present invention relates to cable technology field, a kind of cable for oil platform is provided.
Background technology
Along with the strategic proposition of " accelerate ocean exploration exploitation, realize marine oil and gas fast development ", the construction of offshore oil platform has also entered gold period.Due to the particularity of offshore oil platform to cable requirement, the general Dou Shicong of the cable for petroleum flat U.S., the national import such as Korea S, raising along with offshore oil platform production domesticization level, domestic urgent to the requirement of offshore oil platform private cable, the super soft high-tensile control cables of used for oil platform is for a kind of new product of the Environment Design exploitation of oil platform, cable on oil platform requires soft, tension, oil resistant, high temperature resistant, low temperature resistant, rub resistance etc., to the environmental performance of cable, require high, the common cable of used for oil platform in the past, stretch-proof ability is low, useful life is shorter.
Summary of the invention
The object of the present invention is to provide a kind of resistance to tension good, soft a kind of cable for oil platform.
The present invention is to achieve these goals by the following technical solutions:
A kind of cable for oil platform, it comprises center reinforcement steel wire, four conductors, every conductor is all wrapped with insulating barrier outward, and insulating barrier is wrapped with screen, and screen is wrapped with inner restrictive coating, inner restrictive coating is wrapped with bitumen layer, in bitumen layer, be provided with steel wire, bitumen layer is outside equipped with external sheath layer, between described insulating barrier and screen, is provided with inserts.
In technique scheme, screen comprises Copper Foil, Copper Foil two sides is provided with aluminium foil, under identical thickness, adopts this structure than traditional single more saving copper material of copper layer structure that adopts, saved cost, on the other hand, aluminium foil quality is lighter, thereby has also reduced the weight of screen, screen is evenly equipped with through hole, and exoperidium bulge or the problem of pricking threading core appear in this structure while having avoided using tinsel establishment cable shield.
In technique scheme, described filler is fireproof water-resisting tape, and fireproof water-resisting tape comprises mica layer, and mica layer two sides is bonded with respectively fiberglass gridding braid, and fiberglass gridding braid is bonded with the film consisting of water-proofing powder outward.This structure has organically combined the mica layer with fire-proof function, makes it possess two kinds of functions of waterproof and fire prevention.
In technique scheme, described insulating barrier is polyethylene or polyolefin.
In technique scheme, for external sheath layer adopts thermoplastic elastomer (TPE) TPU material.
Because the present invention adopts above technical scheme, so possess following beneficial effect:
Center of the present invention is provided with reinforcement steel wire, is also provided with steel wire in bitumen layer, and this structure has increased the stretch-proof ability of cable greatly, and the setting of bitumen layer can reach etch-proof object.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The invention discloses a kind of cable for oil platform, it comprises center reinforcement steel wire, four conductors, every conductor is all wrapped with insulating barrier outward, and insulating barrier is wrapped with screen, and screen is wrapped with inner restrictive coating, inner restrictive coating is wrapped with bitumen layer, in bitumen layer, be provided with steel wire, bitumen layer is outside equipped with external sheath layer, between described insulating barrier and screen, is provided with inserts.
In technique scheme, screen comprises Copper Foil, Copper Foil two sides is provided with aluminium foil, under identical thickness, adopts this structure than traditional single more saving copper material of copper layer structure that adopts, saved cost, on the other hand, aluminium foil quality is lighter, thereby has also reduced the weight of screen, screen is evenly equipped with through hole, and exoperidium bulge or the problem of pricking threading core appear in this structure while having avoided using tinsel establishment cable shield.
In technique scheme, described filler is fireproof water-resisting tape, and fireproof water-resisting tape comprises mica layer, and mica layer two sides is bonded with respectively fiberglass gridding braid, and fiberglass gridding braid is bonded with the film consisting of water-proofing powder outward.Water-proofing powder can produce the expansion that is several times as much as original volume after meeting water, causes its intermediate gap of shutoff to prevent the infiltration of water.
This structure has organically combined the mica layer with fire-proof function, makes it possess two kinds of functions of waterproof and fire prevention.
In technique scheme, described insulating barrier is polyethylene or polyolefin.
