Embodiment 1

[0025] Such as figure 1 As shown, a torsion-resistant drum cable structure includes a flexible core strip 1, an insulated core 2, an isolation layer 3, and a sheath layer 4. There are four insulated wire cores 2, which are evenly distributed around the flexible core strip 1, twisted into one strand to surround the flexible core strip 1, and the isolation layer 3 uses a gap wrapping method to surround all the insulated core strips 2 to protect The jacket 4 is squeezed out of the isolation layer 3.

[0026] The flexible core strip 1 is composed of a carbon fiber rope 11 and a flexible adhesive layer 12 wrapped around the carbon fiber rope 11. The material of the flexible adhesion layer 72 is silicone rubber.

[0027] The insulated core 2 includes a conductor 21, a temperature insulating layer 22 wrapped outside the conductor 21, and an insulating layer 23 wrapped outside the temperature insulating layer 22. The conductor 21 is formed by twisting a plurality of annealed annealed c...

Embodiment 2

[0030] The difference between this embodiment and embodiment 1 is that the material formula of the sheath layer 4 is as follows: 100 parts of chlorinated polyethylene rubber, 15 parts of ethylene-butene copolymer, 3 parts of ethylene-vinyl acetate rubber EVA, and magnesium oxide 10 parts, calcium and zinc stabilizer 3 parts, antioxidant 2 parts, stearic acid 0.8 parts, antimony trioxide 9 parts, semi-refined paraffin 2.5 parts, pigment carbon black 18 parts, precipitation method white carbon black 30 parts, active nano 50 parts of kaolin, 18 parts of flame retardant, 19 parts of talc, 21 parts of dioctyl sebacate DOS, 6 parts of auxiliary crosslinking agent, 5 parts of peroxide crosslinking agent.

[0031] The antioxidant includes 1.0 part of antioxidant RD and 1.0 part of antioxidant MB.

[0032] The beneficial effects of this formula are as follows: During the refining process, chlorinated polyethylene rubber, ethylene-butene copolymer and ethylene-vinyl acetate rubber EVA are ad...

Abstract

The invention relates to an anti-torsion reel cable structure comprising a sheath layer, a flexible core strip, insulated wire cores, and an isolation layer. No less than three insulated wire cores are arranged and are distributed around the flexible core strip to form one strand based on twisting, and thus the flexible core strip is encircled. The isolation layer encircles all insulated wire cores in a gap lapping mode; and the sheath layer is extruded outside the isolation layer. According to the invention, the anti-torsion reel cable structure has the following advantages: the isolation layer employs the gap lapping way and thus the insulated wire cores and the sheath layer are in an adhering state; the flexible core strip adheres to the insulated wire cores to form an integrated structure of the cable. Deformation of the appearance and internal structure of the cable and conductor cracking can be avoided when the cable is in anti-torsion high-stress frequent coiling, backing off, and dragging state and after tensile force is eliminated. The stress of the sheath layer due to frequent bending and large external forces can be effectively reduced.

Description

Technical field [0001] The invention relates to a cable structure, in particular to a torsion resistant drum cable structure. Background technique [0002] The reel cable used for heavy mobile equipment is often in a state of frequent reciprocating motion, so its tensile, torsion and fatigue resistance properties are high. The existing reel cable is derived from the general rubber sheathed flexible cable. The usual improvement plan is to adopt a softer conductor structure to improve the non-electrical performance of the sheath or insulation layer, but the overall structure is not improved. Ignore the compactness and stability of the overall structure of the reel cable, and these two characteristics play a decisive role in the service life of the reel cable. [0003] The structure of the existing reel cable is like figure 2 As shown, it includes a cable core, an isolation layer 5 wrapped around the cable core, and a sheath layer 6 wrapped around the isolation layer 5. The cable co...
