Existing cable is simple in structure, and mostly shielding properties is poor, cannot meet diamagnetic, anti-radio frequency, and anlistatig requirement, and present much cables do not merge optical cable, and existing cable is easily received the infringement of animal in the wild when laying.
From 1836, produce in the world Article 1 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 approximately 5000 of the state-owned and above enterprises of scale of China's wires and cables industry, 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 the requirement of the each main industry of national economy to electric wire performance, 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, have a kind of optoelectronic composite cable of cable and properties of optical fiber cable, and its screen quality is light and handy, and copper consumption is few, has pest-resistant harmful ability.
The utility model is to achieve these goals by the following technical solutions:
A kind of high-performance optical photoelectric compound cable with insect protected function, its spy is, comprise sub-thread cable, sub-thread cable comprises 3 root conductors 1 at least, the outer all wrap insulate layers 2 of conductor, at least 2 sub-thread cable conductively-closed layers 4 are wrapped to form sub-thread shielded type cable, filler 3 is filled in gap between screen 4 and sub-thread cable, described screen 4 outer wrapping inner restrictive coatings 5, in inner restrictive coating 5, be provided with at least 3 optical fiber 6, optical fiber 6 is wrapped with nonwoven fabrics 7, inner restrictive coating 5 is wrapped with flame-retardant layer 8, flame-retardant layer 8 is wrapped with watertight composition 9, watertight composition 9 is enclosed with external sheath layer 10, the interior uniform cavity 11 that is provided with of external sheath layer 10, 11 of cavitys are provided with electrical heating elements 12 between two.
Flame-retardant layer 6 comprises the basalt fibre braid of mica layer and parcel mica layer, and described mica layer thickness is 0.2-0.9mm, and flame-retardant layer 6 is enclosed with watertight composition 9;
Watertight composition 9 comprises bonding successively reinforced layer, basic unit, water blocking layer and cover layer, and reinforced layer is copper mesh, and basic unit and cover layer are nonwoven fabrics, and water blocking layer is mica tape or glass fibre;
Described screen 4 is three-decker, comprises Copper Foil, and Copper Foil two sides is equipped with aluminium foil.
Described filling filler 3 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 3 is glass fibre.
Electrical heating elements is that ultra-thin Nb-Al alloy steel band is made euthermic chip, ultra-thin chromium aluminium or chrome-nickel steel band.
Because the utility model adopts above technical scheme, so possess following beneficial effect:
The utility model watertight composition is not easy to expand, thereby avoided watertight composition, expanded by water, pushes optical fiber, thereby affects the problem of Optical Fiber Transmission efficiency.
