Abstract
The utility model discloses a special optoelectrical composite cable in underground with basalt combined material protective layer, including wire, optic fibre and cladding layer, cladding layer is the four -layer structure, is pitch layer, basalt combined material layer, polytetrafluoroethylene layer from inside to outside in proper order, basalt combined material layer comprises basalt non -woven fabrics layer that is located both sides and the mica powder filling layer that is located the centre, the cover is equipped with electromagnetic shield layer on the optic fibre. The compound cable in mainly used underground.
Description
Technical field
The utility model belongs to cable field, is specifically related to a kind of underground special photoelectric composite cable with basalt composite material protective layer.
Background technology
Along with popularizing of information technology, in a lot of outdoor local demand having energising to lead to net.Such as in park, need installing cables and optical cable, because cable and optical cable belong to different division managements respectively, be all independent wiring, which adds workload, but also easily impact each other.How cable and optical cable can be united two into one, just to can solve this problem.The utility model devises a kind of photoelectric integral type underground client cables for this problem just.
Basalt fibre, be basalt building stones after 1450 DEG C ~ 1500 DEG C meltings, by the continuous fiber of platinum-rhodium alloy bushing high speed pulling.Be similar to glass fibre, its performance is between high strength S glass fibre and alkali-free E glass fibre, and the color of pure natural basalt fibre is generally brown, and some is like golden.Basalt fibre is a kind of emerging novel inorganic environment-friendly and green high performance fibre material, the basalt building stones that it is made up of oxides such as silicon dioxide, aluminium oxide, calcium oxide, iron oxide and titanium dioxide after high-temperature fusion, by bushing Defect.Basalt continuous fiber is good stability not only, but also has electrical insulating property, anticorrosive, flame resistant, the multiple excellent properties such as high temperature resistant.In addition, the discarded object that the production technology of basalt fibre produces is few, and environmental pollution is little, can directly proceed in biological environment after product abandonment, without any harm, because of but a kind of genuine green, environment-friendly materials.China is classified as basalt fibre as one of four large fibers (basalt fibre, carbon fiber, aramid fiber, superhigh molecular weight polyethylene fibers) that China gives priority to, substantially achieves suitability for industrialized production in China.Basalt continuous fiber is widely used in many aspects such as fibre reinforced composites, friction material, shipbuilding materials, heat-barrier material, automobile industry, high temperature filtration fabric and protection fields.
Utility model content
The utility model object is to provide a kind of underground special photoelectric composite cable with basalt composite material protective layer, and solving existing cable and optical cable needs independent wiring and the poor problem of water-tight corrosion-proof ability.
The technical solution of the utility model is: a kind of underground special photoelectric composite cable with basalt composite material protective layer; comprise wire, optical fiber and external coating; external coating is four-layer structure; be followed successively by bitumen layer, basalt composite material layer, polytetrafluoroethylene floor from inside to outside; described basalt composite material layer is made up of with the mica powder packed layer being positioned at centre the basalt nonwoven layer being positioned at both sides, and described optical fiber is arranged with electro-magnetic screen layer.
Further, described wire is three, and form by heart yearn and insulation sheath, wherein the heart yearn of two wires is copper cash, and the heart yearn of an other wire is steel wire, and described steel wire surface-coated has graphene layer,
Further, in mica powder packed layer, the particle diameter of mica powder is 1-10 micron.
The utility model compared with prior art tool has the following advantages:
Optical fiber and wire are effectively combined by the utility model, only need once to connect up just to complete the setting of optical fiber and cable.Design especially for underground environment, can increase the service life.
In the utility model, external coating is four-layer structure, has waterproof, anticorrosion, fireproof effect, can improve the useful life of cable under the complex environment of underground.
In the utility model; three wires adopt two copper cash and a root table face to be coated with the steel wire of Graphene; steel wire uses as ground wire; because ground wire does not need to work long hours; therefore steel wire just can meet actual needs; thus can be cost-saving; steel wire surface-coated Graphene; due to high conductivity and the decay resistance of Graphene; not only can improve the conductivity of steel wire, etch-proof effect can also be played, even if when the outer layer protection of cable is ineffective; also can well protect heart yearn not to be corroded, thus increase the service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, Reference numeral is: 1-copper cash, 2-steel wire, 3-optical fiber, 4-electro-magnetic screen layer, 5-bitumen layer, 6-basalt composite material layer, 7-external protection.
