Abstract
The invention relates to the technical field of cables, and provides a cable for a computer. The cable is characterized in that a center reinforced steel wire (1) and four conductors (2) are included, each conductor (2) is wrapped by an insulation layer (3), the insulation layers (3) are wrapped by a shielding layer (4), the shielding layer (4) is wrapped by an inner sheath layer (5), the inner sheath layer is wrapped by an asphalt layer (6), pull reinforcement (7) is arranged in the asphalt layer (6), an outer sheath layer (8) is arranged outside the asphalt layer (6), a filler (9) is arranged between the insulation layers (3) and the shielding layer, the shielding layer (4) comprises a copper foil layer, the two sides of the copper foil layer is plated with aluminum foil layers, and through holes penetrating through the copper foil layer and the aluminum foil layers are further formed.
Description
Technical field
The present invention relates to field of cable technology, provide a kind of computer cable.
Background technology
Along with the proposition of the strategy of " accelerate ocean exploration exploitation, realize marine oil and gas fast development ", the construction of offshore oil platform also enters gold period.Because offshore oil platform is to the particularity of cable needs, cable for petroleum flat is all generally from the U.S., the national import such as Korea S, along with the raising of offshore oil platform production domesticization level, domestic urgent to marine computer cable needs, a kind of new product that super soft high-tensile control cables used for oil platform is developed for the Environment Design of oil platform, cable needs on oil platform is soft, tension, oil resistant, high temperature resistant, low temperature resistant, rub resistance etc., high to the environmental performance demand of cable, used for oil platform common cable in the past, tensile resistance 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, quality is light, and a kind of computer cable being applied to oil platform of the screen that can not there is bulge problem.
The present invention is to achieve these goals by the following technical solutions:
A kind of computer cable, it comprises center and strengthens steel wire, four conductors, every root 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, be provided with steel wire in bitumen layer, bitumen layer is outside equipped with external sheath layer, is provided with inserts between described insulating barrier and screen.Described screen comprises copper foil layer, and copper foil layer two sides is all coated with aluminium foil layer, is also provided with the through hole running through copper foil layer and aluminium foil layer.The screen of the application comprises copper foil layer, Copper Foil two sides is all coated with aluminium foil, under identical thickness, the list adopting this structural rate traditional adopts layers of copper structure more saving copper material, has saved cost, on the other hand, aluminium foil quality is lighter, thus also reducing the weight of screen, screen is evenly equipped with through hole, this configuration avoids the problem occurring exoperidium bulge or bundle threading core when using tinsel establishment cable shield.
In technique scheme, a kind of computer cable, is characterized in that: copper foil layer thickness is 1-2 micron, and aluminium foil layer thickness is 8-10 micron.
In technique scheme, the diameter of described through hole is 400-500 micron.
In technique scheme, screen comprises Copper Foil, Copper Foil two sides is provided with aluminium foil, and under identical thickness, the list adopting this structural rate traditional adopts layers of copper structure more saving copper material, save cost, on the other hand, aluminium foil quality is comparatively light, thus also reduces the weight of screen, screen is evenly equipped with through hole, this configuration avoids the problem occurring exoperidium bulge or bundle threading core when 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 fiberglass gridding braid respectively, is bonded with the film be made up of water-proofing powder outside fiberglass gridding braid.This structure has organically combined the mica layer with fire-proof function, makes it possess waterproof and fire prevention two kinds of functions.
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 considerably increases the tensile resistance of cable, and the setting of bitumen layer can reach etch-proof object.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of computer cable, it comprises center and strengthens steel wire, four conductors, every root 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, be provided with steel wire in bitumen layer, bitumen layer is outside equipped with external sheath layer, is provided with inserts between described insulating barrier and screen.Described screen comprises copper foil layer, and copper foil layer two sides is all coated with aluminium foil layer, is also provided with the through hole running through copper foil layer and aluminium foil layer.The screen of the application comprises copper foil layer, Copper Foil two sides is all coated with aluminium foil, under identical thickness, the list adopting this structural rate traditional adopts layers of copper structure more saving copper material, has saved cost, on the other hand, aluminium foil quality is lighter, thus also reducing the weight of screen, screen is evenly equipped with through hole, this configuration avoids the problem occurring exoperidium bulge or bundle threading core when using tinsel establishment cable shield.
In technique scheme, screen comprises Copper Foil, Copper Foil two sides is provided with aluminium foil, and under identical thickness, the list adopting this structural rate traditional adopts layers of copper structure more saving copper material, save cost, on the other hand, aluminium foil quality is comparatively light, thus also reduces the weight of screen, screen is evenly equipped with through hole, this configuration avoids the problem occurring exoperidium bulge or bundle threading core when 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 fiberglass gridding braid respectively, is bonded with the film be made up of water-proofing powder outside fiberglass gridding braid.Water-proofing powder can produce the expansion being 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 waterproof and fire prevention two kinds of functions.
In technique scheme, described insulating barrier is polyethylene or polyolefin.
