Abstract
The invention relates to the technical field of a cable, and discloses a tension shielding cable for a petroleum platform, for the purpose of providing a cable which is tensile and has a good electromagnetic shielding capability. The cable comprises a conductor. The conductor is externally wrapped by an insulation layer, the insulation layer is externally wrapped by an inner shielding layer, the inner shielding layer is externally wrapped by an asphalt layer, the asphalt layer is internally provided with a steel wire layer, the asphalt layer is externally wrapped by a fireproof layer, the fireproof layer is externally wrapped by an oversheath layer, the steel wire layer is encircled by a plurality of steel wires so as to be arranged to be of an enclosed circular shape, and a filling material is arranged between the inner shielding layer and the asphalt layer.
Description
Technical field
The present invention relates to cable technology field, a kind of tension shielding 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 screen of the cable that former used for oil platform is common adopts tinsel establishment more, easily there is exoperidium bulge or the problem of pricking threading core in cable shield.
Summary of the invention
The object of the present invention is to provide a kind of stretch-proof, the cable that electromagnetic shielding ability is good.
The present invention is by the following technical solutions to achieve these goals:
A kind of tension shielding cable for oil platform, it comprises conductor, conductor is wrapped with insulating barrier, insulating barrier is wrapped with internal shield, and internal shield is wrapped with bitumen layer, is provided with steel wire floor in bitumen layer, bitumen layer is wrapped with flame retardant coating, flame retardant coating is wrapped with external sheath layer, and described steel wire floor is arranged to the garden type of sealing by some steel wire encirclings, and the gap between described internal shield and bitumen layer is provided with filler.
In technique scheme, described filler is waterstop, and waterstop comprises bonding successively copper mesh, nonwoven fabrics and glass fibre.
In technique scheme, described flame retardant coating comprises mica layer and basalt braid, and basalt braid is wrapped in outside mica layer, and described mica layer thickness is 0.3-0.8mm, and the filament diameter of described basalt braid is 0.3-0.8mm.Basalt braid can be good at, by mica parcel, making mica not separated when being heated.
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:
The present invention adopts steel wire encircling distribute to form closed circular electro-magnetic screen layer, and steel wire can increase the resistance to tension of cable, and steel wire floor is arranged in bitumen layer, has effectively increased the antiseptic power of cable.
Accompanying drawing explanation
Fig. 1 is mechanism map of the present invention.
