Description
Technical field
The utility model relates to cable technology field, and a kind of reinforced high shielding properties optoelectronic composite cable is provided.
Background technology
Existing cable is simple in structure, shielding properties is poor mostly, cannot meet diamagnetic, anti-radio frequency, anlistatig requirement, and in existing cable, do not strengthen result, a little less than cable resistance to tension, and the watertight composition of the optical fiber of existing photoelectric compound cable is expanded by water easily, push optical fiber, affect the transmission efficiency of optical fiber.
From 1836, produce in the world article one lv power cable (the wrapped copper conductor of rubber belt) so far, electric wire has developed into a large product category of many uses, various in style.China's wires and cables industry, through the development of more than 70 years, has also been obtained larger progress.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.At present the state-owned and above enterprise of scale of China's wires and cables industry is approximately 5000, and wherein large enterprise has 19, and the gross output value accounts for 11% of whole market share.
Electric wire is to carry the 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 requirement to electric wire performance of national economy, and national economy thinks that most industries are 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.
Summary of the invention
The object of the present invention is to provide a kind of screening ability strong, stretch-proof, watertight composition is not easy to expand, and its screen quality is light and handy, a kind of reinforced high shielding properties optoelectronic composite cable that copper consumption is few.
A kind of reinforced high shielding properties optoelectronic composite cable, its spy is, comprise at least 3 conductors 4, the outer all wrap insulate layers 6 of conductor form sub-thread cable, at least 3 sub-thread cable conductively-closed layer 9 parcels, filler 7 is filled in the gap that screen 9 and insulating barrier are 6, described screen 9 outer wrapping inner restrictive coatings 8, in inner restrictive coating 8, be provided with at least 3 optical fiber 1, optical fiber 1 is wrapped with water blocking layer 2, and inner restrictive coating 8 is wrapped with external sheath layer 5,5 uniform metal wire layers 3 of inner restrictive coating 8 and external sheath layer, screen 9 comprises Copper Foil, and Copper Foil two sides is provided with aluminium foil.Copper Foil two sides is equipped with aluminium foil, and shielding layer structure is novel, and the use of aluminium foil has reduced the consumption of copper, economical and light.
Described water blocking layer 2 comprises bonding successively reinforced layer, 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.Water blocking layer 2 is subject to not allow to produce deformation after water, thereby can not expand and extruding optical fiber because of water blocking layer 2, causes Optical Fiber Transmission rate to decline.
Described filling filler 7 is fireproof water-resisting tape, and it comprises mica layer, and mica layer two sides is adhering glass fiber mesh respectively, and the film that bonding one deck consists of water-proofing powder on fiberglass gridding forms water blocking layer.
Described filling filler 7 is glass fibre.
Beneficial effect:
Stretch-proof, watertight composition is not easy to expand, and its screen quality is light and handy, and copper consumption is few.
Accompanying drawing explanation
Fig. 1 is structure chart of the present utility model.
