SUMMERY OF THE UTILITY MODEL
The utility model discloses the purpose is: the utility model provides a cable with anticorrosive function to solve among the prior art power cable and easily appear structural damage and cause the problem of corroding after a large amount of bending.
The technical scheme of the utility model is that: a cable with corrosion resistance function comprises a plurality of conductors, a filling layer filled outside the conductors, a reinforcing braid layer, a heat-resistant layer, a waterproof layer, an anti-corrosion layer and a protective sleeve, wherein the reinforcing braid layer, the heat-resistant layer, the waterproof layer, the anti-corrosion layer and the protective sleeve are sequentially arranged outwards from the outside of the filling layer; the conductors are distributed in an annular shape, the middle part of the conductors surrounds an inner cavity, and a plurality of small-diameter reinforcing steel wires which are arranged opposite to the conductors are distributed in the middle part of the inner cavity in an annular shape; the conductor is composed of a plurality of stranded copper wires, an insulating layer is coated outside the conductor, and a rubber layer is arranged on the outer sides of the insulating layer and the small-diameter reinforcing steel wires which are arranged oppositely.
Preferably, the filling layer is internally provided with a positioning body which is formed by the middle of the filling layer in a manner of outwards dispersing and comprises a plurality of positioning pieces extending outwards, the conductors are respectively arranged between the adjacent positioning pieces, and the outer wall of the rubber layer is attached to the positioning pieces.
Preferably, the outer diameter of the small-diameter reinforcing steel wire is equal to 1/8-1/5 of the outer diameter of the conductor.
Preferably, the number of copper wires stranded in each conductor is 20-40.
Compared with the prior art, the utility model has the advantages that:
(1) after a large number of copper wires are twisted to form a conductor, the radius of the conductor is relatively large, at the moment, after a plurality of conductors are arranged around the tangent, an inner cavity formed in the middle is large, after the inner cavity is filled with fillers, a large number of bending of cables can damage the fillers, and after a long time, the fillers in the inner cavity are damaged to cause the whole structure to be loose, so that a series of problems such as corrosion easily occur at the moment; in addition, the rubber layer also enables the structure to have certain pressure resistance.
(2) Still be provided with the location body in the filling layer, further improve the inside steadiness of overall structure.
(3) The structure is suitable for the condition that the radius of the conductor is large, so that the number of copper wires stranded in the conductor is 20-40 in the design process.
