Detailed Description

As shown in fig. 1, a wear-resisting anticorrosive tensile flexible cable of silicon rubber insulation, including many conductors 1 and a stranded soft wire rope 2 the outside of conductor 1 and soft wire rope 2 all crowded package has silicon rubber insulating layer 3, put central point with a soft wire rope 2 and put conductor 1 all around respectively, and placed aramid fiber silk 4 between two adjacent conductors 1, with soft wire rope 2, conductor 1 and aramid fiber silk 4 transposition for the cable core, it has high temperature resistant filling rope 5 still to clad in proper order in the cable core outside, polyester area around covering 6, tinned copper wire woven shield 7 and silicon rubber oversheath 8.

The conductor 1 is a tinned copper core soft conductor, and an aramid fiber wire II 9 is arranged in the tinned copper core soft conductor.

The high-temperature filling rope 5 is a polypropylene filling rope.

The utility model discloses a soft conductor of tinned copper core stranded transposition makes the cable have better electric conductive property, also possesses good pliability, and a aramid fiber silk has been placed to the conductor when the bundle hank inside, ensures that every conductor all has tensile strength. When the cable is formed, a soft steel wire rope formed by twisting a plurality of strands of thin steel wires is arranged at the center, and the twisted thin soft steel wire rope has good flexibility and excellent tensile property. The outer part of the steel wire rope is coated with a layer of silicon rubber insulating layer, so that the steel wire rope can not damage the surrounding insulating wire cores in the process of winding the cable. And an aramid fiber yarn is placed in the filling position between every two conductors, so that the overall tensile property of the cable is improved. The cable core is wrapped by the polyester tape, the tinned copper wire shielding layer is woven, the tinned copper wire improves the oxidation resistance of the copper wire, current is prevented from leaking along the radial direction, the use safety is ensured, and the anti-interference performance of the cable in severe environment is enhanced. The insulating layer and the sheath layer of the cable are both made of silicon rubber, the silicon rubber has excellent insulating property, good corona resistance and arc resistance, and high-temperature stability, and can still keep certain flexibility, rebound resilience and surface hardness under the high-temperature environment of more than 200 ℃, the mechanical property is not obviously changed, the low-temperature resistance is also good, and the cable can still work under the temperature of-55 ℃. And the silicone rubber also has good oil resistance and chemical reagent property, and has better wear resistance and corrosion resistance. The cable has the advantages that the structural design of each layer fully considers the characteristics of wear resistance, corrosion resistance, tensile strength, flexibility and the like of the cable, the tensile strength design is superior to that of the traditional tensile cable, and the performance is improved to a certain extent.
