Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clear, embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

As shown in figure 1, the utility model provides a low-smoke halogen-free environment-friendly reel cable, which comprises a wrapping layer 4, a shielding layer 5 and an outer sheath layer 6 which are concentrically arranged from inside to outside, wherein three wire cores which are equidistantly distributed along the circumferential direction of the wrapping layer 4 are arranged in the wrapping layer 4, the wire cores all comprise wire core conductors 1, insulating layers 2 are extruded outside the wire core conductors 1, each insulating layer 2 is tangent to the wrapping layer 4, every two adjacent insulating layers 2 are tangent to each other, a steel wire bearing unit 3 is arranged between every two adjacent insulating layers 2 and the wrapping layer 4, the steel wire bearing units 3 are respectively tangent to the wrapping layer 4 and the insulating layers 2, specifically, the steel wire bearing units 3 are formed by twisting a plurality of soft steel wires, so that the flexibility of the reel cable is not influenced, the self weight of the reel cable can be borne by arranging the steel wire bearing units 3, and if the laying distance is far, the deformation degree of the reel cable under the action of traction force can be reduced by the steel wire bearing units 3, the service life of the reel cable is prolonged; in addition, a plurality of protruding structures 61 are arranged outside the outer sheath layer 6 and are distributed at equal intervals along the circumferential direction of the outer sheath layer 6, the protruding structures 61 are all arranged along the axial direction of the outer sheath layer 6 and are integrated with the outer sheath layer 6 into a whole, and specifically, the outer sheath layer 6 and the protruding structures 61 are made of low-smoke halogen-free flame-retardant polyolefin materials, so that the reel cable still has the performances of environmental protection and no pollution and has good flexibility; through set up the protruding structure 61 that a plurality of equidistance distributes in 6 circumference in outer sheath layer, lay the reel cable and with the frictional in-process in ground, will wear and tear protruding structure 61 at first, can prolong the life of outer sheath layer 6 like this to improve the life of reel cable.

Further, as shown in fig. 1, groove structures 62 have been all seted up along oversheath layer 6 axial on the oversheath layer 6 between per two adjacent protruding structures 61, and groove structures 62's cross-section is triangle-shaped, and is concrete, still need carry out the rolling with its winding on the reel after the reel cable uses, so can reduce the tangential stress that the reel cable received when winding is crooked on the reel through setting up groove structures 62, further improve the life of reel cable.
