Abstract
A fire-proof and waterproof computer cable comprises a central reinforcement steel wire (1) and four conductors (2). Each conductor (2) is wrapped by an insulating layer (3), the insulating layers (3) are wrapped by a shielding layer (4), the shielding layer (4) is wrapped by a fire-proof and waterproof layer (5) which is wrapped by an asphalt layer (6), dead-drawn wires (7) are arranged in the asphalt layer (6), an outer sheath layer (8) is arranged outside the asphalt layer (6), and fillings (9) are arranged between the insulating layers (3) and the shielding layer. The fire-proof and waterproof layer (5) comprises a copper mesh, an expansion particle layer, a mica layer and a basalt braid layer in sequence, the thickness of each mica layer is 0.3-0.8 mm, and the monofilament diameter of each basalt braid layer is 0.3-0.8 mm.
Description
Technical field
The present invention relates to field of cable technology, provide a kind of fire-resistant computer cable blocked water.
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 the requirement of offshore oil platform private cable, 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, the soft a kind of fire-resistant computer cable blocked water.
The present invention is to achieve these goals by the following technical solutions:
A kind of fire-resistant computer cable blocked water, it is characterized in that: comprise center and strengthen steel wire, four conductors, every root conductor is all wrapped with insulating barrier outward, insulating barrier is wrapped with screen, screen is wrapped with fire-resistant water blocking layer, fire-resistant water blocking layer is wrapped with bitumen layer, be provided with in bitumen layer and draw by force, bitumen layer is outside equipped with external sheath layer, inserts is provided with between described insulating barrier and screen, fire-resistant water blocking layer comprises the copper mesh set gradually, expanded granular layer, mica layer is (with basalt braid, described mica layer thickness is 0.3-0.8mm, the filament diameter of described basalt braid is 0.3-0.8mm.Basalt braid of the present invention can be good at mica to wrap up, and mica is not separated when being heated, and expanded granular layer 2 expands by after water, and make it block water, copper wire layer can play anti-electromagnetic interference capability.
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 fire-resistant computer cable blocked water, it comprises center and strengthens steel wire, four conductors, every root conductor is all wrapped with insulating barrier outward, insulating barrier is wrapped with screen, screen is wrapped with fire-resistant water blocking layer, fire-resistant water blocking layer is wrapped with bitumen layer, be provided with in bitumen layer and draw by force, bitumen layer is outside equipped with external sheath layer, inserts is provided with between described insulating barrier and screen, fire-resistant water blocking layer comprises the copper mesh set gradually, expanded granular layer, mica layer is (with basalt braid, described mica layer thickness is 0.3-0.8mm, the filament diameter of described basalt braid is 0.3-0.8mm.Basalt braid of the present invention can be good at mica to wrap up, and mica is not separated when being heated, and expanded granular layer 2 expands by after water, and make it block water, copper wire layer can play anti-electromagnetic interference capability.
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.
