Description
Technical field
The utility model design communication technical field, provides the corrosion resistant photoelectric compound cable of a kind of fire-proof and damp-proof.
Background technology
(letter out thread 22 years) March in 1897, China's first underground power cable knocks down use in Shanghai, and the light conduits of the most edge sheath sheath of those the 2700 meters of long rubbers used then is imported product.Until after 42 years (nineteen thirty-nine) just produce the domestic cable of root of informing against in Kunming (cable factory).Before 1949, wires and cables industry only has worker more than 2000 people, production equipment about 500, year the highest copper consumption only 6500 tons.Wherein Kunming, Shanghai, Tianjin, four, Shenyang Electric Wire Factory share copper 5700 tons, and output accounts for 87.7% of the whole nation, wires and cables industry slower development.Until after New China was founded in l949, the wires and cables industry of China just obtains develop rapidly.
Electric wire is the conveying energy, the indispensable basic equipment of transmission of information, and from the today in social informatization, electrified fast development, electric wire has become one of most important basic product in economic construction.Wires and cables industry is again supporting industry, and product must meet each main industry of national economy to the requirement of electric wire performance, and national economy thinks that most industry is all relevant to electric wire, and its industrial status is very important.China's wires and cables industry is still in developing stage at present, and as the important guide's industry of the development of the national economy, the growth of electric wire production and marketing index is generally higher than total value of production in national economy outline.
Traditional cable and optical fiber mostly are split, optoelectronic composite cable structure is less, photoelectricity composite demand softness, tension, oil resistant, high temperature resistant, low temperature resistant, rub resistance etc., high to the environmental performance demand of cable, screen many employings tinsel establishment of used for oil platform common cable in the past, easily there is exoperidium bulge or pricks the problem of threading core in cable shield.
To specific as hot environment, the fire prevention of cable, optical cable seems particularly important, but present cable, optical cable many employings mica bring fire prevention, and its fire protecting performance is poor, can not meet certain Production requirement.
And for specific wet environment, moistureproof, anticorrosion seems particularly important to cable, optical fiber, and traditional cable, optical cable are after oversheath is damaged, there is oxide etch problem to inner screen etc.
Utility model content
The purpose of this utility model is to provide a kind of fire-proof and damp-proof corrosion resistant photoelectric compound cable.
The utility model is by the following technical solutions to achieve these goals:
The corrosion resistant photoelectric compound cable of a kind of fire-proof and damp-proof, is characterized in that, comprise the optical fiber 2 set gradually from the inside to the outside, optical fiber ointment 2, steel armour restrictive coating 3, Filled Dielectrics layer 4, anti-corrosion asphalt layer 5, flame retardant coating 7, external sheath layer 8, is enclosed with screen 6 in described anti-corrosion asphalt layer 5, screen 6 comprises internal layer compound copper-plastics band, outer magnalium braid over braid, Filled Dielectrics layer 4 comprise micropore is set have fabric strip, flame-retardant layer, watertight composition, flame-retardant layer, fabric strip, watertight composition bond successively.
Technique scheme, described flame-retardant layer is comprise the copper mesh, expanded granular layer, the mica layer that set gradually, and described mica layer thickness is 0.3-0.8mm, and the filament diameter of described copper mesh is 0.3-0.8mm.When expanded granular layer is by the time of tide, volumetric expansion, thus form extruding between particle, form waterproof shield.
Technique scheme, watertight composition comprises reinforced layer bonding successively, basic unit, water blocking layer and cover layer, and described reinforced layer is copper mesh, and basic unit and cover layer are nonwoven fabrics, and water blocking layer is mica tape or glass fibre.
Because the utility model adopts above technical scheme, therefore possess following beneficial effect:
One, the utility model adopts pitch to be wrapped up by screen, can reach certain waterproof effect, can prevent again the oxidized corrosion of screen.
Two, when expanded granular layer is by the time of tide, volumetric expansion, thus form extruding between particle, form waterproof shield, water resistance is good.
Three, the utility model anticorrosion on the whole, waterproof, fire protecting performance are good, and overall structure is uncomplicated, lighter weight.
Four, the setting of bitumen layer solves bulge problem to a certain extent.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
