Abstract
The utility model discloses an anti-moisture corrosion-resistant insulated cable for tunnels, which is composed of conductors, an insulating layer, a shielding layer and an outer sheath. The shielding layer and the insulating layer are squeezed outside the conductors. The conductors form a cable core together through a PVC plastic connecting rod. Four ground line cores are arranged at the gaps between the cable core and the insulating layer. The outer sheath, a stainless steel wire braided armored anti-corrosion protective layer and an aluminum-plastic composite belt are successively squeezed outside the shielding layer from outside to inside. In summary, the anti-moisture corrosion-resistant insulated cable for the tunnels has advantages of: high insulating performance, high anti-oxidation performance, high water resistance, high conductivity and high magnetic interference resistance. The anti-moisture corrosion-resistant insulated cable can be widely applied for the fields of ship, tunnel, etc.
Description
Technical field
The utility model relates to field of cables, relates in particular to a kind of moistureproof corrosion-resistant tunnel insulated cable.
Background technology
At present, along with socioeconomic development, electric wire consumption increases rapidly, the quality requirement of electric wire is also constantly improved, such as at boats and ships, the electric wire of the use fields such as tunnel in, to the anti-oxidation water resistance of electric wire, conductance, the requirement of diamagnetic jamming performance aspect is all high especially.If the incomplete words that electric wire possesses, can affect work and benefit and safety in these fields.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of moistureproof corrosion-resistant tunnel insulated cable.
The utility model takes following technical scheme to realize: a kind of moistureproof corrosion-resistant tunnel insulated cable, and it is to be made up of conductor, insulating barrier, screen and oversheath, described conductor is outward to be extruded and formed by screen and insulating barrier; Between described conductor, jointly form cable core by PVC plastics connecting rod; The gap location of described cable core and insulating barrier arranges four ground wire cores; Described screen ecto-entad is that oversheath, stainless steel wire braiding armour and aluminium-plastic tape jointly extrude and form; Described conductor is to form by multiply silver-gilt copper wire is stranded; Described insulating barrier is that low smoke halogen-free flame-retardant polyolefin insulating material or cross-linking polyethylene materials are made; The count of described stainless steel wire braiding armour is not less than 88%.
[0005]the utlity model has in sum following beneficial effect: this electric wire has good insulation property, anti-oxidation water resistance, and conductance is high, and diamagnetic jamming performance is excellent, is widely used in the field such as boats and ships, tunnel.
