Abstract

The utility model discloses a special optoelectrical composite cable in underground based on basalt combined material is waterproof anticorrosive, including wire, optic fibre and cladding layer, the wire is three, evenly distributed outside optic fibre, the cover is equipped with electromagnetic shield layer on the optic fibre, and cladding layer is the four -layer structure, is pitch layer, basalt combined material layer, external coating from inside to outside in proper order, basalt combined material layer comprises basalt non -woven fabrics layer that is located both sides and the cream filling layer that blocks water that is located the centre. Mainly used underground optoelectrical composite cable.

Description

A kind of underground special photoelectric composite cable based on basalt composite material water-tight corrosion-proof
Technical field
The utility model belongs to cable field, is specifically related to a kind of underground special photoelectric composite cable based on basalt composite material water-tight corrosion-proof.
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.
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 based on basalt composite material water-tight corrosion-proof, solves the problem that existing cable and optical cable need independent wiring and water-tight corrosion-proof.
The technical solution of the utility model is: a kind of underground special photoelectric composite cable based on basalt composite material water-tight corrosion-proof; comprise wire, optical fiber and external coating; described wire is three; be evenly distributed on outside optical fiber; described optical fiber is arranged with electro-magnetic screen layer; external coating is four-layer structure; be followed successively by bitumen layer, basalt composite material layer, external protection from inside to outside, described basalt composite material layer is made up of with the waterproof paste packed layer being positioned at centre the basalt nonwoven layer being positioned at both sides.
Further, wire is formed by heart yearn and PVC crust, and wherein the heart yearn of two wires is copper cash, and the heart yearn of an other wire is silver-plated steel wire.
Further, electro-magnetic screen layer is aluminium foil.
Further, described external protection adopts thermoplastic elastic material.
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, adopt the external coating of four-layer structure, anticorrosion, waterproof, fire-retardant effect can be played.
In the utility model, three wires adopt two copper cores and a silver-plated steel wire, and silver-plated steel wire uses as ground wire, and because ground wire does not need to work long hours, therefore silver-plated steel wire just can meet actual needs, thus can be cost-saving.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, Reference numeral is: 1-copper cash, the silver-plated steel wire of 2-, 3-optical fiber, 4-electro-magnetic screen layer, 5-bitumen layer, 6-basalt composite material layer, 7-external protection.
